TeleBrief ("we", "our", or "the app") is a Telegram channel and group summarization tool that helps you digest your Telegram conversations quickly. This Privacy Policy explains what data we access, how it is used, and your rights as a user.
TeleBrief uses Telegram's official TDLib library to let you sign in with your Telegram account (phone number and verification code, or QR code login). This authentication happens directly between your device and Telegram's own servers over Telegram's encrypted MTProto protocol.
When a summary is generated — either manually or via the twice-daily scheduled brief — the relevant channel/group messages are sent to:
Free-trial and standard server-plan usage may be served using Google's free-tier API, for which Google's terms permit use of prompt/response data to improve their products. Paid subscription plans and BYOK with your own paid-tier key are served through Google's paid tier, which Google does not use to train its models. We do not control how Google processes data once received, and recommend reviewing its policies directly. Message content is sent only at the moment of summarization and is not stored by us after the request completes.
Because channels and groups include messages from people other than you, please only add channels/groups where you're a legitimate participant and be mindful of the expectations of other members — they have not individually consented to AI processing of their messages.
We use the following Firebase services (operated by Google LLC) to improve app stability and understand usage patterns:
These services are subject to Google's Privacy Policy.
TeleBrief uses Supabase for backend services — account/device management, routing AI summarization requests through our server-side key pool, and subscription status. Supabase is subject to its own Privacy Policy. We do not store your Telegram message content on Supabase beyond the brief moment a summarization request is in transit.
If you choose to subscribe to a paid plan, payment is processed by Razorpay. We store your plan type and subscription status; we do not store your card or payment instrument details — those are handled entirely by Razorpay, subject to its own Privacy Policy.
Messages, summaries, and preferences are stored locally on your device and remain under your control. You can clear all app data at any time via Android Settings → Apps → TeleBrief → Clear Data, or remove individual channels/groups from within the app. Logging out of Telegram inside the app clears your local TDLib session. Every scheduled digest run also automatically deletes messages older than 10 days from your device, whether or not they were summarized — summaries themselves are kept until you delete them or clear app data. We do not retain your message content on our servers beyond the duration of a single summarization request.
TeleBrief is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can delete it.
Your Telegram session is managed by TDLib over Telegram's own encrypted MTProto protocol. API keys are stored using Android's encrypted DataStore. Messages and summaries are stored in a SQLCipher-encrypted local database. We apply reasonable technical measures to protect your data, though no method of transmission over the internet is 100% secure.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy.
