Account Activity and Settings Data
Posted: Thu May 29, 2025 6:17 am
Purpose: Provides the highest level of privacy and security, as the data never touches Telegram's servers in an unencrypted or decryptable form.
Metadata:
Telegram collects some metadata necessary for the service to function, such as sender/recipient IDs, timestamps of messages, and IP addresses.
While Telegram generally aims to minimize metadata collection, the exact extent and retention policies for various types of metadata are less transparent than the content encryption.
Beyond messages, a Telegram data account also includes information about how the user interacts with the service and their chosen configurations:
Contact List (Optional): If a user grants permission, Telegram can sync their phone's contact list to help them find friends on Telegram and suggest new contacts. This data is stored on Telegram's servers.
Privacy Settings: The user's chosen configurations for who can see their phone number, last seen status, profile picture, who can add them to groups, and who can call them. These settings are stored server-side.
Security Settings: Information related to Two-Step Verification (cloud password), active sessions telegram data (logged-in devices), and account auto-deletion settings.
Bot Subscriptions & Interactions: Data related to which bots a user has started chats with and the data exchanged with those bots.
Channel and Group Memberships: A list of channels and groups the user is subscribed to or a member of. For private channels/groups, this data is kept internal. For public ones, it's inherently discoverable.
Customization Data: Theme settings, chat backgrounds, notification preferences.
