Practical safety guide
Set up Telegram more safely
2. Privacy
Limit visibility of the phone number, last seen, profile photos and forwarded messages. Restrict who can add the account to groups and call it.
3. Public content
Explain that usernames, public groups and bots can expose young users to strangers. Block and report harmful accounts and channels.
Final check: confirm privacy, communication, account protection, content, purchases and reporting tools. Review settings again after major app or game updates.
