Hi,
communities are no longer discussing whether telegram is "secure". It
stores the communication on central servers that are under control of a
quite unknown entity. Because of this, telegram can offer features that
other messengers can't.
But it's not secure.
Please consider changing the package description to something like
"feature-rich messaging application". People who want to be secure are
better served with alternatives.
Thanks for your consideration.
Greetings
Marc
P.S.: That being said, telegram is my favorite messenger because I
appreciate the features. your mileage may vary.
