 <p>Adding push notifications for iOS required SimpleX Messaging Protocol changes. We managed not just to keep the same level of meta-data privacy from passive observers, but to improve it - now all message meta-data that is passed from the server to the recipient is included into the same encrypted envelope as the message itself - as before, there is no identifiers or ciphertext in common inside TLS traffic between received and sent traffic of the server, and now there is no message timestamp inside TLS as well.</p>
 <p>We also improved the protocol flow for establishing bidirectional connection between two users - it is substantially faster now, consuming much less network traffic and battery. It improves the time it takes to connect to your contacts and to start delivering images and files.</p>
-<p>All these changes did not affect backward compatibility - if your contact has the previous version of the client, or you are connecting to a previous version of the server, the previous version of the protocol will be used - SimpleX has independent version negotiation in 4 protocol layers <a href="https://simplex.chat/blog/20220112-simplex-chat-v1-released.html">since v1</a>, allowing us to evolve the protocols without any disruption to the users.</p>

 <p>For additional security of your messages you also have the option to remove the passphrase from the device. In this case you will need to enter the passphrase every time you start the app. The notifications will continue to work only while the app is in the background. For iOS it means that periodic and local notifications will work, but instant notifications will only show that there is a message available, but not message content or who it is from - you will need to open the app and enter the passphrase to see the messages. In this case, if you lose the passphrase, you will not be able to open the app or decrypt the database - so make sure you store it safely.</p>

 &lt;p&gt;One major initiative we will kick-off this year is the support for large, fully decentralized and private communities and groups not hosted on any servers – something that no Internet platform achieved so far in as private and efficient way as we plan to build it.&lt;/p&gt;
 &lt;p&gt;To accelerate product development and growth we will be raising a seed funding this year, both from the VCs and angel investors, and we also might offer our users an opportunity to participate in the crowd funding round on the same terms as other investors, allowing to both support the project and to benefit from its future growth. &lt;a href=&quot;https://simplex.chat/#join-simplex&quot;&gt;Subscribe to our updates&lt;/a&gt; not to miss it, connect to the team in SimpleX Chat and &lt;a href=&quot;https://github.com/simplex-chat/simplex-chat#join-user-groups&quot;&gt;join users&#39; groups&lt;/a&gt;.&lt;/p&gt;

 &lt;p&gt;With the new XFTP protocol that allows sending files up to 1gb it is now possible to increase the message size - we decided to limit it at 5 min, increasing their quality 2x (the bitrate is increased from 16 to 32kbps). We also added a slider to control the playback.&lt;/p&gt;

 &lt;p&gt;You&#39;ve found the workaround for it of course - it&#39;s enough to simply edit the message to hide the original content.

 &lt;p&gt;Most messaging apps add two ticks to sent messages – the first one to show that the message is accepted by the server, and the second – that it is delivered to the recipient&#39;s device. It confirms that the network is functioning, and that the message is not lost or delayed. SimpleX Chat now has this feature too!&lt;/p&gt;
 &lt;p&gt;In some cases it may compromise recipients&#39; privacy, as they show that the recipient is online, so we made sending delivery receipts optional – it can be disabled separately for each chat profile or contact. For the new chat profiles this feature is enabled by default.&lt;/p&gt;

 &lt;p&gt;Previously, a growing number of users had the issue when after restoring the chat database from backup, messages from some contacts failed to decrypt and were showing an error in the app.&lt;/p&gt;
-&lt;p&gt;This happens due to double ratchet protocol protecting the integrity of end-to-end encryption after the compromise - &lt;a href=&quot;https://simplex.chat/docs/glossary.html&quot;&gt;post-compromise security&lt;/a&gt;. The protocol logic does not allow to use the old version of the database to decrypt the message.&lt;/p&gt;
-&lt;p&gt;v5.2 added the extension to the messaging protocol allowing to negotiate the new ratchet keys in such cases - both with the contacts and the group members. This requires a user action, and it resets the security code verification status for this contact or member – you need to verify it again to have the additional protection from &lt;a href=&quot;https://simplex.chat/docs/glossary.html&quot;&gt;man-in-the-middle attacks&lt;/a&gt;.&lt;/p&gt;

 &lt;p&gt;The negotiation of the new ratchet keys still happens via the end-to-end encrypted messages, as the protocol has two layers of end-to-end encryption, so it cannot be compromised by the messaging relays.&lt;/p&gt;
 &lt;p&gt;You may still lose connection if you or your contact changed the receiving address after you made the backup, so make sure to make a new backup after any receiving address changes.&lt;/p&gt;

 &lt;h4 id=&quot;why-not-hosted-groups-with-mls&quot; tabindex=&quot;-1&quot;&gt;Why not hosted groups with MLS?&lt;/h4&gt;
 &lt;p&gt;Initially, we considered the design with the dedicated servers, potentially self-hosted, that host groups. This design would require adopting MLS (or similar) protocol for group-wide key agreement. Unfortunately, this design is not sufficiently resilient and easier to censor than decentralized design. Also, MLS protocol is very complex to implement, requires a centralized component, and reduces forward secrecy. So we decided against this approach.&lt;/p&gt;
 &lt;h4 id=&quot;why-not-fully-decentralized-groups&quot; tabindex=&quot;-1&quot;&gt;Why not fully decentralized groups?&lt;/h4&gt;
-&lt;p&gt;We also &lt;a href=&quot;https://github.com/simplex-chat/simplex-chat/blob/stable/simplex-chat/docs/rfcs/2023-05-02-groups.md&quot;&gt;considered&lt;/a&gt; rumour-mongering protocol, where all members are equal and participate in message dissemination. The problem with this approach is that it adds a lot of traffic for all members, even those who mostly read messages. Also, it still requires establishing a fully connected graph, and with large groups it becomes prohibitively expensive and unreliable, given that many members join public groups for a limited time.&lt;/p&gt;
+&lt;p&gt;We also &lt;a href=&quot;https://simplex.chat/blog/https%3A//github.com/simplex-chat/simplex-chat/blob/stable/simplex-chat/docs/rfcs/2023-05-02-groups.md&quot;&gt;considered&lt;/a&gt; rumour-mongering protocol, where all members are equal and participate in message dissemination.

 &lt;h4 id=&quot;members-host-the-groups&quot; tabindex=&quot;-1&quot;&gt;Members host the groups&lt;/h4&gt;
 &lt;p&gt;We are now considering a middle-ground - the design where the owners and admins host the group, synchronising the state between them, receiving and re-broadcasting the messages between all members. This puts a higher burden on these members, but these clients can be hosted in the cloud, and also group owners have a larger incentive to maintain group integrity. At the same time, this design is better for the rest of the group members, as they don&#39;t need to establish connections with all other members, only with a limited number of &amp;quot;hosting&amp;quot; members, and it also better protects their privacy, due to the lack of direct connections between most members.&lt;/p&gt;
 &lt;p&gt;This approach avoids the need for a group-wide key agreement protocol, as hosting members are expected to have access to all content anyway, so pair-wise ratchets are sufficient. At the same time the content remains end-to-end encrypted, and protected from the outsiders.&lt;/p&gt;
 &lt;p&gt;This approach also simplifies moderation - the message that needs to be removed simply won&#39;t reach the members before it is moderated (in case of automatic or policy-based moderation).&lt;/p&gt;
-&lt;p&gt;Discovery and content search in such groups will be provided via a dedicated discovery server that will participate in the group, provide an always-online client, and also automatic content moderation functionality - a possible approach to moderation is &lt;a href=&quot;https://github.com/simplex-chat/simplex-chat/blob/stable/simplex-chat/docs/rfcs/2023-05-22-groups-moderation.md&quot;&gt;described here&lt;/a&gt;.&lt;/p&gt;

 &lt;p&gt;If it is an Android app, you can move the app to background, but iOS app has to remain open. In both cases, while you are using mobile profiles from desktop, you won&#39;t be able to use mobile app.&lt;/p&gt;
 &lt;p&gt;The subsequent connections happen much faster - by default, the desktop app broadcasts its session address to the network, in encrypted form, and mobile app connects to it once you choose &lt;em&gt;Use from desktop&lt;/em&gt; in mobile app settings.&lt;/p&gt;

 &lt;p&gt;This solution is similar to WhatsApp and WeChat. But unlike these apps, no server is involved in the connection between mobile and desktop. The connection itself uses a new SimpleX Remote Control Protocol (XRCP) based on secure TLS 1.3 and additional quantum-resistant encryption inside TLS. You can read XRCP protocol specification and threat model in &lt;a href=&quot;https://github.com/simplex-chat/simplexmq/blob/master/rfcs/2023-10-25-remote-control.md&quot;&gt;this document&lt;/a&gt;.

 &lt;p&gt;The downside of this approach is that mobile device has to be connected to the same local network as desktop. But the upside is that the connection is secure, and you do not need to have a copy of all your data on desktop, which usually has lower security than mobile.&lt;/p&gt;
 &lt;p&gt;Please note, that the files you send, save or play from desktop app, and also images you view are automatically saved on your desktop device (encrypted by default except videos). To remove all these files you can unlink the paired mobile device from the desktop app settings – there will be an option soon allowing to remove the files without unlinking the mobile.&lt;/p&gt;

 &lt;h2 id=&quot;why-do-we-need-end-to-end-encryption&quot; tabindex=&quot;-1&quot;&gt;Why do we need end-to-end encryption?&lt;/h2&gt;
 &lt;p&gt;The objective of end-to-end encryption is to make any potential attackers, such as traffic observers or communication providers who pass the messages between senders and recipients, unable to recover &lt;em&gt;any&lt;/em&gt; message content or meaningful information about the messages, even if these attackers possess very advanced computing and mathematical capabilities.&lt;/p&gt;

 &lt;p&gt;The only effective mitigation to these attacks is to pad all messages to a fixed size. Using space-efficient schemes like Padme, or padding to encryption block size is ineffective for mitigating these attacks, as they still allow differentiating message sizes.&lt;/p&gt;
 &lt;p&gt;To the best of our knowledge, the only messengers other than SimpleX Chat that pad all messages to a fixed packet size are Cwtch and no longer developed &lt;a href=&quot;https://github.com/agl/pond&quot;&gt;Pond&lt;/a&gt; - SimpleX design can be seen as an evolution of Pond design.&lt;/p&gt;

-&lt;p&gt;Many users are very interested in having ability to irreversibly delete sent messages from the recipients devices. But not only would this ability violate data sovereignty of device owners, it is also completely ineffective, as the recipients could simply put the device offline or use a modified client app to ignore message deletion requests. While SimpleX Chat provides such features as &lt;a href=&quot;https://simplex.chat/blog/20230103-simplex-chat-v4.4-disappearing-messages.html&quot;&gt;disappearing messages&lt;/a&gt; and the ability to &lt;a href=&quot;https://simplex.chat/blog/20221206-simplex-chat-v4.3-voice-messages.html&quot;&gt;irreversibly delete sent messages&lt;/a&gt; provided both parties agree to that, these are convenience features, and they cannot be considered security measures.&lt;/p&gt;

 &lt;p&gt;The solution to that is well known to cryptographers - it is the quality of the encryption algorithms called &amp;quot;repudiation&amp;quot;, sometimes also called &amp;quot;deniability&amp;quot;. This is the ability of the senders to plausibly deny having sent any messages, because cryptographic algorithms used to encrypt allow recipients forging these messages on their devices, so while the encryption proves authenticity of the message to the recipient, it cannot be used as a proof to any third party.&lt;/p&gt;
 &lt;p&gt;Putting it all in a simpler language - a sender can claim that the recipient forged messages on their device, and deny ever having sent them. The recipient will not be able to provide any cryptographic proof. This quality makes digital conversation having the same qualities as private off-the-record conversation - that&#39;s why the family of algorithms that provide these qualities are called off-the-record (OTR) encryption.&lt;/p&gt;
 &lt;p&gt;Repudiation is still a rather new concept - the first off-the-record algorithms were proposed in 2004 and were only offered to a wide range of users in Signal messenger. This concept is still quite badly understood by users and society, and yet to have been used as the defense in any public court cases, as legal systems evolve much slower than technology. In high profile cases repudiation can be used as an effective evidence for the defense.&lt;/p&gt;

 &lt;p&gt;Since we added the audio and video calls in 2022 a lot of work was done to improve the stability of calls. One of the usability downsides until this release was that it was impossible to use the app during the call.&lt;/p&gt;
 &lt;p&gt;This version solved this problem - now you can return back to the app without interrupting the call and use any of the app functions - for example, you can send the messages or files to the person you are in the call with.

 &lt;p&gt;This is called &lt;a href=&quot;https://en.wikipedia.org/wiki/Metadata&quot;&gt;metadata&lt;/a&gt;. It reveals a wealth of information about you and your connections, and in the hands of a centralized monopoly, this can and does get misused in incredibly dangerous ways. Once such metadata is logged, it can create very detailed profiles about who you are, everywhere you’ve been, and everyone you’ve ever spoken to. In settling for apps that normalize this while giving you the illusion of privacy in their marketing, we are doing ourselves a disservice by accepting this as the default. Collectively, we aren’t doing enough to protect ourselves and our social graph from this invasive overreach.&lt;/p&gt;

 &lt;p&gt;This is one of the many reasons why we need to resist giving out our phone numbers just to access an app, especially to do something as personal and intimate as private messaging. Even though users can sometimes mask their numbers with a username, their identity on the app is still fundamentally tied to their phone number. App operators have access to this, as well as user contacts. Additionally, with a simple modification to the app&#39;s source code, the contacts may also gain access in some cases. This should raise more concerns about privacy, and it makes the need for anonymity difficult to achieve.&lt;/p&gt;
 &lt;p&gt;Everyone has a different threat model (and if you don’t yet, now is a good time to &lt;a href=&quot;https://www.privacyguides.org/en/basics/threat-modeling/#creating-your-threat-model&quot;&gt;create one&lt;/a&gt;). For many users today, WhatsApp and other apps may be sufficient for their specific needs, especially in connecting with families and friends who are already on the app and unlikely to migrate elsewhere. If that suits your life and needs, and if you’re aware and consciously accept the risks, great.&lt;/p&gt;

 &lt;p&gt;One of the main considerations often ignored in security and privacy comparisons between messaging applications is multi-device access. For example, in Signal’s case, the Sesame protocol used to support multi-device access has the vulnerability that is &lt;a href=&quot;https://eprint.iacr.org/2021/626.pdf&quot;&gt;explained in detail here&lt;/a&gt;:&lt;/p&gt;
 &lt;p&gt;&lt;em&gt;&amp;quot;We present an attack on the post-compromise security of the Signal messenger that allows to stealthily register a new device via the Sesame protocol. [...] This new device can send and receive messages without raising any ‘Bad encrypted message’ errors. Our attack thus shows that the Signal messenger does not guarantee post-compromise security at all in the multi-device setting&amp;quot;&lt;/em&gt;.&lt;/p&gt;
 &lt;img src=&quot;https://simplex.chat/blog/images/20231125-mobile2.png&quot; width=&quot;170&quot; class=&quot;float-right&quot; /&gt;
-&lt;p&gt;Solutions are possible, and even the quoted paper proposes improvements, but they are not implemented in any existing communication solutions. Unfortunately this results in most communication systems, even those in the privacy space, having compromised security in multi-device settings due to these limitations. That&#39;s the reason we are not rushing a full multi-device support, and currently only provide &lt;a href=&quot;https://simplex.chat/blog/20231125-simplex-chat-v5-4-link-mobile-desktop-quantum-resistant-better-groups.html&quot;&gt;the ability to use mobile app profiles via the desktop app&lt;/a&gt;, while they are on the same network.&lt;/p&gt;

 &lt;p&gt;Another choice that compromises privacy for convenience and usability is 3rd party push notifications. At SimpleX, we take a slow path of optimizing the network and battery consumption in the app, rather than simply hiding inefficiencies behind the quick fix solution of 3rd party push notifications that &lt;a href=&quot;https://www.wired.com/story/apple-google-push-notification-surveillance/&quot;&gt;increases vulnerability&lt;/a&gt;, a path Signal and others chose. Like other choices, it has usability and optimization trade offs, but ultimately it’s the right thing to continue progressing towards a better solution as we explain &lt;a href=&quot;https://simplex.chat/blog/20220404-simplex-chat-instant-notifications.html&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;
 &lt;p&gt;Whenever possible, we strive to achieve significantly higher levels of privacy and security. For example, unlike most, if not all, applications (including Signal), &lt;a href=&quot;https://simplex.chat/blog/20230925-simplex-chat-v5-3-desktop-app-local-file-encryption-directory-service.html#encrypted-local-files-and-media-with-forward-secrecy&quot;&gt;we encrypt application files with per-file unique key&lt;/a&gt;. Consequently, once a message is deleted, there&#39;s no means to open a file that someone may have stolen in hopes of acquiring the key later. Similarly, apps like Session have done away with forward secrecy, a decision which caused them &lt;a href=&quot;https://www.privacyguides.org/en/real-time-communication/#additional-options&quot;&gt;not to be recommended&lt;/a&gt; for &amp;quot;long-term or sensitive communications&amp;quot;. And &lt;a href=&quot;https://simplifiedprivacy.com/spain-has-banned-telegram-defending-session/&quot;&gt;misinformation&lt;/a&gt; around this makes it dangerous and irresponsible to recommend without such necessary disclosures for people’s awareness.&lt;/p&gt;
-&lt;p&gt;Session’s decision was based on &lt;a href=&quot;https://getsession.org/blog/session-protocol-explained&quot;&gt;the incorrect statements&lt;/a&gt; about double ratchet being impossible in decentralized networks, and underplayed importance of forward secrecy, break-in recovery and deniability - the absence of these crucial qualities makes Session a much weaker choice for private messaging. For transparency, this was something that was debated with their team &lt;a href=&quot;https://twitter.com/SimpleXChat/status/1755216356159414602&quot;&gt;here&lt;/a&gt;.

 &lt;p&gt;It&#39;s important to recognize that a model of decentralization where all servers are openly known and accessible to all clients, that some users ask for, actually results in a less decentralized network, and as the network grows it often requires an introduction of a central authority to protect from bad actors with malicious intent. Therefore, we&#39;ve deliberately opted for a slower path towards achieving a higher degree of decentralization where there is no central server registry or network authority. For example, p2p designs may offer higher initial decentralization but often compromise on privacy and eventual decentralization. In essence, our approach prioritizes a balance between initial decentralization, privacy, and higher degree of decentralization down the line.&lt;/p&gt;

 &lt;p&gt;Where it stands today, users have the freedom to select their preferred servers within the SimpleX network by configuring the app, with thousands of self-hosted servers in operation. Moreover, numerous third-party applications rely on our code for their in-app communications, operating independently of our servers, many of which we may not even be aware of.&lt;/p&gt;
 &lt;p&gt;Decentralization is an ongoing journey, and we strive to proceed at a measured pace to ensure its proper implementation. While the immediate results may not always appear ideal, prioritizing a careful approach ensures that in the long run, the decisions made in this area align with our ultimate objectives of a private, efficient, reliable and fully decentralized network.&lt;/p&gt;
 &lt;h2 id=&quot;funding-and-profitability&quot; tabindex=&quot;-1&quot;&gt;Funding and profitability&lt;/h2&gt;
-&lt;p&gt;We explain our rationale for funding &lt;a href=&quot;https://simplex.chat/faq/index.html&quot;&gt;here&lt;/a&gt;. Funding sources is always one of the most difficult choices to make, and it’s important to underline that VC models don’t necessarily translate to a quest for control, interference of any kind, or overall influence on product roadmap and strategy. The vast majority of investors seek profitability. Irrespective of the organization type profitability is essential for a sustainable operation, and it can and should be done while adhering to the highest possible standards for privacy. For-profit vs. nonprofit is also not an accurate metric to measure a commitment towards privacy and open standards, which is further explained &lt;a href=&quot;https://simplex.chat/blog/20240404-why-i-joined-simplex-chat-esraa-al-shafei.html&quot;&gt;here&lt;/a&gt;.&lt;/p&gt;

 &lt;p&gt;To make a profit, satisfying customers is the key. Unlike the many companies that profit from selling customer data, we put user privacy first. Doing this at scale requires investments. If the investors don’t own or control a company, their participation becomes merely about profit for them, and not about how this profit is obtained. With the investors we have, we are completely aligned on this - they are betting on the future where privacy is the norm. They do not dictate on anything related to our model. We build SimpleX chat, protocols and network the way Internet should have been built if we as developers always put the privacy and empowerment of users first.&lt;/p&gt;

 <p>One of the main considerations often ignored in security and privacy comparisons between messaging applications is multi-device access. For example, in Signal’s case, the Sesame protocol used to support multi-device access has the vulnerability that is <a href="https://eprint.iacr.org/2021/626.pdf">explained in detail here</a>:</p>
 <p><em>"We present an attack on the post-compromise security of the Signal messenger that allows to stealthily register a new device via the Sesame protocol. [...] This new device can send and receive messages without raising any ‘Bad encrypted message’ errors. Our attack thus shows that the Signal messenger does not guarantee post-compromise security at all in the multi-device setting"</em>.</p>

 <p>Another choice that compromises privacy for convenience and usability is 3rd party push notifications. At SimpleX, we take a slow path of optimizing the network and battery consumption in the app, rather than simply hiding inefficiencies behind the quick fix solution of 3rd party push notifications that <a href="https://www.wired.com/story/apple-google-push-notification-surveillance/">increases vulnerability</a>, a path Signal and others chose. Like other choices, it has usability and optimization trade offs, but ultimately it’s the right thing to continue progressing towards a better solution as we explain <a href="https://simplex.chat/blog/20220404-simplex-chat-instant-notifications.html">here</a>.</p>
 <p>Whenever possible, we strive to achieve significantly higher levels of privacy and security. For example, unlike most, if not all, applications (including Signal), <a href="https://simplex.chat/blog/20230925-simplex-chat-v5-3-desktop-app-local-file-encryption-directory-service.html#encrypted-local-files-and-media-with-forward-secrecy">we encrypt application files with per-file unique key</a>. Consequently, once a message is deleted, there's no means to open a file that someone may have stolen in hopes of acquiring the key later. Similarly, apps like Session have done away with forward secrecy, a decision which caused them <a href="https://www.privacyguides.org/en/real-time-communication/#additional-options">not to be recommended</a> for "long-term or sensitive communications". And <a href="https://simplifiedprivacy.com/spain-has-banned-telegram-defending-session/">misinformation</a> around this makes it dangerous and irresponsible to recommend without such necessary disclosures for people’s awareness.</p>
-<p>Session’s decision was based on <a href="https://getsession.org/blog/session-protocol-explained">the incorrect statements</a> about double ratchet being impossible in decentralized networks, and underplayed importance of forward secrecy, break-in recovery and deniability - the absence of these crucial qualities makes Session a much weaker choice for private messaging.

 <p>It's important to recognize that a model of decentralization where all servers are openly known and accessible to all clients, that some users ask for, actually results in a less decentralized network, and as the network grows it often requires an introduction of a central authority to protect from bad actors with malicious intent. Therefore, we've deliberately opted for a slower path towards achieving a higher degree of decentralization where there is no central server registry or network authority. For example, p2p designs may offer higher initial decentralization but often compromise on privacy and eventual decentralization. In essence, our approach prioritizes a balance between initial decentralization, privacy, and higher degree of decentralization down the line.</p>

 <p>Where it stands today, users have the freedom to select their preferred servers within the SimpleX network by configuring the app, with thousands of self-hosted servers in operation. Moreover, numerous third-party applications rely on our code for their in-app communications, operating independently of our servers, many of which we may not even be aware of.</p>
 <p>Decentralization is an ongoing journey, and we strive to proceed at a measured pace to ensure its proper implementation. While the immediate results may not always appear ideal, prioritizing a careful approach ensures that in the long run, the decisions made in this area align with our ultimate objectives of a private, efficient, reliable and fully decentralized network.</p>

Funding sources is always one of the most difficult choices to make, and it’s important to underline that VC models don’t necessarily translate to a quest for control, interference of any kind, or overall influence on product roadmap and strategy. The vast majority of investors seek profitability. Irrespective of the organization type profitability is essential for a sustainable operation, and it can and should be done while adhering to the highest possible standards for privacy.

 <p>To make a profit, satisfying customers is the key. Unlike the many companies that profit from selling customer data, we put user privacy first. Doing this at scale requires investments. If the investors don’t own or control a company, their participation becomes merely about profit for them, and not about how this profit is obtained. With the investors we have, we are completely aligned on this - they are betting on the future where privacy is the norm. They do not dictate on anything related to our model. We build SimpleX chat, protocols and network the way Internet should have been built if we as developers always put the privacy and empowerment of users first.</p>

 <p>This is called <a href="https://en.wikipedia.org/wiki/Metadata">metadata</a>. It reveals a wealth of information about you and your connections, and in the hands of a centralized monopoly, this can and does get misused in incredibly dangerous ways. Once such metadata is logged, it can create very detailed profiles about who you are, everywhere you’ve been, and everyone you’ve ever spoken to. In settling for apps that normalize this while giving you the illusion of privacy in their marketing, we are doing ourselves a disservice by accepting this as the default. Collectively, we aren’t doing enough to protect ourselves and our social graph from this invasive overreach.</p>
-<p>When stored, aggregated and analyzed, this metadata provides ample information that could potentially incriminate someone or be submitted to authorities.

 <p>This is one of the many reasons why we need to resist giving out our phone numbers just to access an app, especially to do something as personal and intimate as private messaging. Even though users can sometimes mask their numbers with a username, their identity on the app is still fundamentally tied to their phone number. App operators have access to this, as well as user contacts. Additionally, with a simple modification to the app's source code, the contacts may also gain access in some cases. This should raise more concerns about privacy, and it makes the need for anonymity difficult to achieve.</p>
 <p>Everyone has a different threat model (and if you don’t yet, now is a good time to <a href="https://www.privacyguides.org/en/basics/threat-modeling/#creating-your-threat-model">create one</a>). For many users today, WhatsApp and other apps may be sufficient for their specific needs, especially in connecting with families and friends who are already on the app and unlikely to migrate elsewhere. If that suits your life and needs, and if you’re aware and consciously accept the risks, great.</p>

 <p>This version solved this problem - now you can return back to the app without interrupting the call and use any of the app functions - for example, you can send the messages or files to the person you are in the call with.

 <h2 id="why-do-we-need-end-to-end-encryption" tabindex="-1">Why do we need end-to-end encryption?</h2>
 <p>The objective of end-to-end encryption is to make any potential attackers, such as traffic observers or communication providers who pass the messages between senders and recipients, unable to recover <em>any</em> message content or meaningful information about the messages, even if these attackers possess very advanced computing and mathematical capabilities.</p>
@@ -490,7 +490,7 @@
 <p>The only effective mitigation to these attacks is to pad all messages to a fixed size. Using space-efficient schemes like Padme, or padding to encryption block size is ineffective for mitigating these attacks, as they still allow differentiating message sizes.</p>
 <p>To the best of our knowledge, the only messengers other than SimpleX Chat that pad all messages to a fixed packet size are Cwtch and no longer developed <a href="https://github.com/agl/pond">Pond</a> - SimpleX design can be seen as an evolution of Pond design.</p>

 <p>The solution to that is well known to cryptographers - it is the quality of the encryption algorithms called "repudiation", sometimes also called "deniability". This is the ability of the senders to plausibly deny having sent any messages, because cryptographic algorithms used to encrypt allow recipients forging these messages on their devices, so while the encryption proves authenticity of the message to the recipient, it cannot be used as a proof to any third party.</p>
 <p>Putting it all in a simpler language - a sender can claim that the recipient forged messages on their device, and deny ever having sent them. The recipient will not be able to provide any cryptographic proof. This quality makes digital conversation having the same qualities as private off-the-record conversation - that's why the family of algorithms that provide these qualities are called off-the-record (OTR) encryption.</p>
 <p>Repudiation is still a rather new concept - the first off-the-record algorithms were proposed in 2004 and were only offered to a wide range of users in Signal messenger. This concept is still quite badly understood by users and society, and yet to have been used as the defense in any public court cases, as legal systems evolve much slower than technology. In high profile cases repudiation can be used as an effective evidence for the defense.</p>

 &lt;p&gt;If it is an Android app, you can move the app to background, but iOS app has to remain open. In both cases, while you are using mobile profiles from desktop, you won&#39;t be able to use mobile app.&lt;/p&gt;
 &lt;p&gt;The subsequent connections happen much faster - by default, the desktop app broadcasts its session address to the network, in encrypted form, and mobile app connects to it once you choose &lt;em&gt;Use from desktop&lt;/em&gt; in mobile app settings.&lt;/p&gt;

 &lt;p&gt;This solution is similar to WhatsApp and WeChat. But unlike these apps, no server is involved in the connection between mobile and desktop. The connection itself uses a new SimpleX Remote Control Protocol (XRCP) based on secure TLS 1.3 and additional quantum-resistant encryption inside TLS. You can read XRCP protocol specification and threat model in &lt;a href=&quot;https://github.com/simplex-chat/simplexmq/blob/master/rfcs/2023-10-25-remote-control.md&quot;&gt;this document&lt;/a&gt;.

 &lt;p&gt;The downside of this approach is that mobile device has to be connected to the same local network as desktop. But the upside is that the connection is secure, and you do not need to have a copy of all your data on desktop, which usually has lower security than mobile.&lt;/p&gt;
 &lt;p&gt;Please note, that the files you send, save or play from desktop app, and also images you view are automatically saved on your desktop device (encrypted by default except videos). To remove all these files you can unlink the paired mobile device from the desktop app settings – there will be an option soon allowing to remove the files without unlinking the mobile.&lt;/p&gt;

 &lt;p&gt;Most messaging apps add two ticks to sent messages – the first one to show that the message is accepted by the server, and the second – that it is delivered to the recipient&#39;s device. It confirms that the network is functioning, and that the message is not lost or delayed. SimpleX Chat now has this feature too!&lt;/p&gt;
 &lt;p&gt;In some cases it may compromise recipients&#39; privacy, as they show that the recipient is online, so we made sending delivery receipts optional – it can be disabled separately for each chat profile or contact. For the new chat profiles this feature is enabled by default.&lt;/p&gt;

 &lt;p&gt;Previously, a growing number of users had the issue when after restoring the chat database from backup, messages from some contacts failed to decrypt and were showing an error in the app.&lt;/p&gt;
-&lt;p&gt;This happens due to double ratchet protocol protecting the integrity of end-to-end encryption after the compromise - &lt;a href=&quot;https://simplex.chat/docs/glossary.html&quot;&gt;post-compromise security&lt;/a&gt;. The protocol logic does not allow to use the old version of the database to decrypt the message.&lt;/p&gt;
-&lt;p&gt;v5.2 added the extension to the messaging protocol allowing to negotiate the new ratchet keys in such cases - both with the contacts and the group members. This requires a user action, and it resets the security code verification status for this contact or member – you need to verify it again to have the additional protection from &lt;a href=&quot;https://simplex.chat/docs/glossary.html&quot;&gt;man-in-the-middle attacks&lt;/a&gt;.&lt;/p&gt;

 &lt;h4 id=&quot;why-not-hosted-groups-with-mls&quot; tabindex=&quot;-1&quot;&gt;Why not hosted groups with MLS?&lt;/h4&gt;
 &lt;p&gt;Initially, we considered the design with the dedicated servers, potentially self-hosted, that host groups. This design would require adopting MLS (or similar) protocol for group-wide key agreement. Unfortunately, this design is not sufficiently resilient and easier to censor than decentralized design. Also, MLS protocol is very complex to implement, requires a centralized component, and reduces forward secrecy. So we decided against this approach.&lt;/p&gt;

The problem with this approach is that it adds a lot of traffic for all members, even those who mostly read messages. Also, it still requires establishing a fully connected graph, and with large groups it becomes prohibitively expensive and unreliable, given that many members join public groups for a limited time.&lt;/p&gt;

 &lt;h4 id=&quot;members-host-the-groups&quot; tabindex=&quot;-1&quot;&gt;Members host the groups&lt;/h4&gt;
 &lt;p&gt;We are now considering a middle-ground - the design where the owners and admins host the group, synchronising the state between them, receiving and re-broadcasting the messages between all members. This puts a higher burden on these members, but these clients can be hosted in the cloud, and also group owners have a larger incentive to maintain group integrity. At the same time, this design is better for the rest of the group members, as they don&#39;t need to establish connections with all other members, only with a limited number of &amp;quot;hosting&amp;quot; members, and it also better protects their privacy, due to the lack of direct connections between most members.&lt;/p&gt;
 &lt;p&gt;This approach avoids the need for a group-wide key agreement protocol, as hosting members are expected to have access to all content anyway, so pair-wise ratchets are sufficient. At the same time the content remains end-to-end encrypted, and protected from the outsiders.&lt;/p&gt;

 &lt;p&gt;SimpleX Chat focus has always been on protecting messages in delivery, not when they are stored on the device. This release changes it - now all messages that you receive and send are stored on the device encrypted with &lt;a href=&quot;https://github.com/sqlcipher/sqlcipher&quot;&gt;SQLCipher&lt;/a&gt;.&lt;/p&gt;

 &lt;p&gt;For additional security of your messages you also have the option to remove the passphrase from the device. In this case you will need to enter the passphrase every time you start the app. The notifications will continue to work only while the app is in the background. For iOS it means that periodic and local notifications will work, but instant notifications will only show that there is a message available, but not message content or who it is from - you will need to open the app and enter the passphrase to see the messages. In this case, if you lose the passphrase, you will not be able to open the app or decrypt the database - so make sure you store it safely.&lt;/p&gt;

 &lt;p&gt;Secret groups made SimpleX Chat much more useful, but because SimpleX groups are completely decentralized and for them to work each member should connect to all other members, sometimes these connections fail and the group becomes fragmented - some members do not receive all messages. That was more common for larger groups, as the number of required member connections is O(n^2) of the group size.&lt;/p&gt;

-&lt;p&gt;To protect identities of users and their connections, instead of user identifiers visible to the servers and/or the network (that are used by all other messaging platforms), SimpleX Chat uses &lt;a href=&quot;https://csrc.nist.gov/glossary/term/Pairwise_Pseudonymous_Identifier&quot;&gt;pairwise identifiers&lt;/a&gt; of connections between the users – there are two queues in each connection, each queue having 2 different identifiers to send and to receive the messages. It increases the number of used identifiers to the square of the number of users, making it more difficult (or impossible) to determine who is talking to whom. I &lt;a href=&quot;https://simplex.chat/blog/20220711-simplex-chat-v3-released-ios-notifications-audio-video-calls-database-export-import-protocol-improvements.html&quot;&gt;wrote previously&lt;/a&gt; why it is bad for the users&#39; privacy to have any identifiers, even random numbers, associated with their profiles.&lt;/p&gt;

 &lt;p&gt;To deliver the notifications to iOS devices we use our notification server, as there is a single private key that Apple issues for the app. This server has minimal amount of information about your chat activity:&lt;/p&gt;

 &lt;li&gt;it does not have the addresses of messaging queues used to send and receive messages - there is an additional address used for notification server to receive notifications from the messaging servers.&lt;/li&gt;

 &lt;p&gt;Adding push notifications for iOS required SimpleX Messaging Protocol changes. We managed not just to keep the same level of meta-data privacy from passive observers, but to improve it - now all message meta-data that is passed from the server to the recipient is included into the same encrypted envelope as the message itself - as before, there is no identifiers or ciphertext in common inside TLS traffic between received and sent traffic of the server, and now there is no message timestamp inside TLS as well.&lt;/p&gt;
 &lt;p&gt;We also improved the protocol flow for establishing bidirectional connection between two users - it is substantially faster now, consuming much less network traffic and battery. It improves the time it takes to connect to your contacts and to start delivering images and files.&lt;/p&gt;
-&lt;p&gt;All these changes did not affect backward compatibility - if your contact has the previous version of the client, or you are connecting to a previous version of the server, the previous version of the protocol will be used - SimpleX has independent version negotiation in 4 protocol layers &lt;a href=&quot;https://simplex.chat/blog/20220112-simplex-chat-v1-released.html&quot;&gt;since v1&lt;/a&gt;, allowing us to evolve the protocols without any disruption to the users.&lt;/p&gt;

You can then invite contacts to the group by entering the &lt;code&gt;/a &amp;lt;group&amp;gt; &amp;lt;name&amp;gt;&lt;/code&gt; command. Your contact(s) will need to use the &lt;code&gt;/j accept&lt;/code&gt; command to accept the invitation to the group. To send messages to the group, simply enter &lt;code&gt;#&amp;lt;group&amp;gt; &amp;lt;message&amp;gt;&lt;/code&gt;.&lt;/p&gt;
 &lt;p&gt;&lt;strong&gt;Please note:&lt;/strong&gt; Groups are not stored on any server; they are maintained as a list of members in the app database. Sending a message to the group sends a message to each member of the group.&lt;/p&gt;

 &lt;p&gt;&lt;strong&gt;Please note:&lt;/strong&gt; SimpleX Chat is in early stage development: we are still iterating protocols, improving privacy and security, so if you have communication scenarios requiring high security, you should consider some other options for now.&lt;/p&gt;
