+You may participate in a public group and receive content from a public channel (Group). In case you send messages or comments to the Group, you grant a license:
+- to all recipients:
+  - to share your messages with the new Group members and outside of the group, e.g. via quoting (replying), forwarding and copy-pasting your message. When your message is deleted or marked as deleted, the copies of your message will not be deleted.
+  - to retain a copy of your messages according to the Group settings (e.g., the Group may allow irreversible message deletion from the recipient devices for a limited period of time, or it may only allow to edit and mark messages as deleted on recipient devices). Deleting message from the recipient devices or marking message as deleted revokes the license to share the message.
+- to Group owners: to share your messages with the new Group members as history of the Group. Currently, the Group history shared with the new members is limited to 100 messages.
+
+Group owners may use chat relays or automated bots (Chat Relays) to re-broadcast member messages to all members, for efficiency. The Chat Relays may be operated by the group owners, by preset operators or by 3rd parties. The Chat Relays have access to and will retain messages in line with Group settings, for technical functioning of the Group. Neither you nor group owners grant any content license to Chat Relay operators.

 1. Automatic message queue rotation and redundancy. Currently the queues created between two users are used until the queue is manually changed by the user or contact is deleted. We are planning to add automatic queue rotation to make these identifiers temporary and rotate based on some schedule TBC (e.g., every X messages, or every X hours/days).
 2. Message "mixing" - adding latency to message delivery, to protect against traffic correlation by message time.
