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.

signal used to send a handy message to your contacts saying "x is on signal now, say hi!", but I think that's stopped now.

@ligniform That was why I installed telegram on a blank tablet. It was sad that I had to confirm a phone number, but, Ok, that's the same with almost every messenger now exept Matrix/Elements, but they got other issues.

@ligniform It's a clear breach of European data protection laws and should be prosecuted. I am angry.

We use it with non-nerd groups, and it works perfect. Even some people 60+ have no problems at all. Still people think, that it is not working, cause 15 years ago it was a pain in the ass to use. But this times are over.

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 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...

@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 ... :-/
