After Delhi High Court ruling, Telegram discloses personal details of users
Don't use messengers that ask for your phone number and aren't end-to-end encrypted.Use services that store as little data as possible.If data is stored, it can be given away and I would assume that it will be given away.Telegram disguises itself as encrypted chat app, when it is actually just a regular centralized plaintext messenger that has an encryption feature that nobody uses.
