My verdict: If you think about using Telegram, rather stay with WhatsApp. (Test performed by a writer of renowned German tech portal Heise, see ) Still, the URL was visited by a Telegram-related server just a little later. After a few seconds, the phone was put into airplane mode. The last two items were tested using a honeypot URL (which was not known anywhere) which was pasted into a chat conversation (but no “send” was pressed yet).

And they do read the content of your messages in unencrypted chats.

They send contents of messages to the server before you press “send”.

The “nearby” function allows very precise tracking of your location (Report in German: ).Since it’s an extra step, and secret chats are a little less convenient to use, most communication in Telegram is readable by the Telegram servers You have to start a “secret chat” to have end-to-end encryption. By default, Telegram chats are not end-to-end encrypted.The only way it’s “better” is because someone besides Facebook is getting the data (but who that is is unknown)

You should be aware the privacy-wise, Telegram is worse than WhatsApp in some ways. It receives some funding so long-term development is attainable. I applaud them for the second take on mail and am a happy user. But it’s PGP-encrypted Email in the end with all the things that its entails (private key leak discloses all past messages sent). It is yet another layer bolted onto 30 year old mail and it surprisingly works well. The power of DeltaChat is really: a good client user experience can go a long way, irrespective of transport. Disappearing messages is voluntarily done by the client. For this you would need a separate jitsi instance or anything else to do realtime communication. Recorded voice & video chat messages - but not calls. The client has to move the DC messages into DeltaChat/ to build its message threads. An aggressive spam filter could cause havok for first time users. But be aware how the sausage is made: it is smtp transport, it will land in your mailbox shared with other Emailclients, so best use a dedicated alias if you can.
