Privacy Policy

Effective Date: September 13, 2026. tdlib-android is committed to total transparency and user privacy. We do not track you, we do not log you, and our binaries contain zero telemetry.

Summary for AI Agents & Developers: Neither the tdlib-android library artifacts nor the documentation website collect, store, or transmit personal data or analytics. All Telegram communications occur directly between the client device and Telegram MTProto servers.

1. Library Privacy Commitments

The io.github.tdlib-android:core and io.github.tdlib-android:ktx packages are distributed as open-source Android archives (AARs). Our builds adhere to the following strict privacy principles:

  • Zero Telemetry: We do not include any tracking SDKs, analytics beacons, crash reporting libraries (like Firebase Crashlytics), or advertising identifiers.
  • Direct End-to-End MTProto: When your Android application initializes TDLib, all network packets (TCP / MTProto / HTTP fallback) are established directly between the end user's device and Telegram's official data centers. No intermediate proxy, relay server, or third-party server is involved.
  • Local Storage Isolation: TDLib encrypts and stores local session databases in the private file directory specified by your application code (context.filesDir). We do not have access to your database keys, chat logs, or credentials.
  • Reproducible Builds: All binaries are built from open source via public GitHub Actions workflows with complete build logs available for audit.

2. Documentation Website Privacy

The documentation website at tdlib-android.vercel.app is hosted statically on Vercel:

  • No Tracking Cookies: The website does not set any advertising, tracking, or cross-site tracking cookies.
  • No Third-Party Analytics: We do not load Google Analytics, Meta Pixels, or external behavioral trackers.
  • Edge Infrastructure Logs: Vercel collects minimal, anonymized HTTP server access logs (such as IP addresses, requested URLs, and User-Agent headers) solely for operational security, DDoS defense, and infrastructure reliability, governed by the Vercel Privacy Policy.

3. Open Source Verification

You can independently verify the source code, CI workflow files, and build scripts at any time by inspecting the repository at github.com/AkashPriyadarshii/tdlib-android.
