Oh nice. For a test project I installed a #telegram app on a tablet with an empty #adressbook only to find out that it send out that information to obviously every Telegram user that had my number in their adressbook. How illegal...

And that happened BEFORE I could adjust any settings during the setup. I dont think I just missed that, but that is a big fail. It's been a while, but does #Signal do the same? I hate such practice.

@mfeilner No, Signal doesn’t do that. To establish contacts, the Signal client only sends an cryptographically obfuscated (hashed) version of the phone numbers in your address book to a Signal server (making extra sure that the server’s code has not been tampered with, by using a clever reversal of DRM technology). It does not send the cleartext of your address book. You can find background information on Signal’s technologies and algorithms on Signal’s blog at https://signal.org/blog/.

@ujay68 Does Telegram use a similar safe concept for that? And isnt the following true? Still the information is transfered in a "hey, this chap is now also here" way...

@mfeilner Don’t know about Telegram and won’t ever even think of touching it. 😉

@ujay68 Yeah, it's for a project, and I am feeling strongly that I know why I dont use it otherwise. And we haven't talked about the Russian impact here yet ... :-/
