(#wt5j2xq) @deebs Yup saw this the other day here The most interesting part for me was these two tid-bits: **Signal:** - *No message content. - *Date and time a user registered. - *Last date of a user’s connectivity to the service. **Telegram:** - *No message content. - *No contact information provided for law enforcement to pursue a court order. As per Telegram’s privacy statement, for confirmed terrorist investigations, Telegram may disclose IP and phone number to relevant authorities.

(#wt5j2xq) I am not familiar with the functionality of Telegram or Signal, but things I have heard about both make me skeptical of their entries in this document. Signal requires a phone number to sign up, and I believe that you can connect it to your contact list on your phone to find other people using Signal. If this is the case, wouldn't they have to store at least a hash of your phone number? Hashed information is listed elsewhere in the document.

(#wt5j2xq) From what I've heard about Telegram, you have to explicitly enable end-to-end encryption with another person and you can't do that in group chats. Shouldn't that be listed in the document? It's very likely that I'm wrong in all this, can anyone familiar with Signal or Telegram confirm?
