Signal still have access to your contact list at first, they simply not store it anywhere. Which is good for me

I understand, but if you are new to this conversation app, right after installing it would be good to know which of your contacts your are able to talk to there. I don’t see asking one by one and adding them manually a good solution, maybe there is another one I don’t see

What is the problem in asking for pulling your contact list? Isn’t it to check which of your contacts also have telegram?
