Description

Search across notifications, accessibility and indexed files. Everything stays encrypted on-device with SQLCipher AES-256-CBC + Android Keystore. No AI, no cloud, no account, no internet permission.

  • Search notifications, accessibility and files
  • Prefix and wildcard matching
  • Search term highlighting in results
  • Statistics with timeline charts and breakdown by content type
  • System app blocking for unwanted sources
  • Full encryption at rest (SQLCipher + Android Keystore)
  • Zero network — no internet permission, no telemetry
  • Open source (GPL-3.0-only)

What’s new (0.9.0)
