Activity Trace

Ever see something on your phone and then struggle to find it again? ActivityTrace creates a private, searchable memory of your Android activity. Search notifications, captured screen content, and indexed files from one place. No Internet permission. No cloud. No account. No telemetry. Your data stays encrypted on your device. • Find what you saw — one searchable timeline of notifications, screen content and files • Search naturally — type "yesterday", "last week" or plain keywords • Filter precisely — by app (in:signal) or content type (type:notification), with prefix matching, ranked results and highlighting • You control retention — choose how long data is kept and block individual apps • See when and where — statistics about captured activity over time • Encrypted at rest — SQLCipher AES-256-CBC + Android Keystore • Theme support — system default, light, dark, or OLED black • Demo mode — try ActivityTrace with fictional data, fully separate from your real activity Privacy isn't a promise — it's an architecture. ActivityTrace has no Internet permission, so there is no hidden analytics endpoint, no cloud sync, and no telemetry waiting to be disabled. Your data cannot leave your device. Free and open source software (GPL-3.0-only). Distributed via F-Droid: no Google Play Services, no proprietary dependencies, no AI or ML components.
