Implication: Hiding profile photos from strangers prevents them from building a visual profile of you. You can also manually delete old profile photos.
Forwarded Messages:
Who can add a link to my account when forwarding my messages? When someone forwards a message you've sent, Telegram can optionally link back to your profile. Options: "Nobody," "My Contacts," "Everybody."
Implication: Setting this to "Nobody" prevents your account from being directly linked when your messages are forwarded, enhancing anonymity in public or group contexts. Your name will still appear, but without the direct clickable link.
Calls:
Controls who can initiate a voice or video call with you on Telegram. Options: "Nobody," "telegram data My Contacts," "Everybody."
Peer-to-Peer: This advanced setting affects call quality and IP address exposure.
Everybody / My Contacts: By default, P2P calls directly connect devices, potentially exposing your IP address to the other party.
Nobody: Routes calls through Telegram's servers, masking your IP address but potentially affecting call quality.
Implication: Setting "Who can call me" to "My Contacts" and "Peer-to-Peer" to "Nobody" significantly enhances call privacy.
Groups & Channels:
Who can add me to group chats? Prevents unwanted additions to spammy or irrelevant groups. Options: "Nobody," "My Contacts," "Everybody."
Implication: Setting this to "My Contacts" is generally recommended to avoid being added to random groups.
Voice Messages:
Who can send me voice messages? Available for Telegram Premium users. Options: "Nobody," "My Contacts," "Everybody."
Implication: Allows Premium users to filter out unwanted voice messages.
