Maestro Scraper runs entirely locally. Your Telegram session is encrypted with your OS keychain; other app data is stored in plaintext on your computer.

​
Encrypted Storage

Your Telegram session is encrypted using your operating system’s native keychain:
  • macOS: Keychain
  • Windows: DPAPI (Data Protection API)
  • Linux: libsecret or kwallet
This means your Telegram session is protected by your OS login credentials. Other app data (channel preferences, address history, activity logs) is stored locally but not encrypted.

​
What Data Is Stored

  • Telegram session - An encrypted session token that keeps you logged in
  • API credentials - Only if “Remember credentials” is checked
  • Channel scraping preferences - Which channels you’re scraping and filter settings
  • Address history - Previously detected addresses (for duplicate detection)
  • Activity logs - A log of scraping events
  • App settings - Your preferences (duplicate filtering, bot selection, etc.)

​
What Data Is NOT Stored

  • Your Telegram password is never stored
  • Message content is not persisted (only processed in memory)
  • No data is sent to external servers except the Maestro bot, Telegram’s own API, and Sentry for error tracking

​
Bot Communication

When forwarding addresses to Maestro, the app sends a formatted message containing:
  • The detected address(es)
  • A link to the source message (if available)
