Hey, buddy! You seriously need to see how easy it is to delete your Telegram account on your phone! I know, I know, it sounds like a chore, but trust me, it's a breeze. Just a few taps, and you're free from all the group chats and notifications!
So, from the moment you open the app, you'll want to head to the Settings menu. It's usually found in the bottom right corner, and it looks like a little cogwheel. From there, you can scroll down to Privacy and Security, and then Delete Account. Easy peasy!
