Deleting your account will permanently erase all your messages and contacts. Groups and channels you created will become ownerless (but admin rights remain), and your creator status will be removed.
If you want to delete your account immediately, follow these steps:
Account deletion is irreversible; if you register again, you'll appear as a new user and won't be able to recover your history, contacts, or groups;
We recommend using a non-mobile browser for this process.
