Core features

  • Quick capture of notes and tasks; everything lands in one connected life graph.
  • Ask: instant search plus an on-device AI assistant over your own memory, with voice input.
  • Timeline of your life with filters, albums, and day-to-year zoom.
  • Local reminders, calendar awareness, and gentle proactive cards that always explain “why”.

Privacy and policy

  • Local-first: your memory lives in an encrypted database on your device.
  • No account, no analytics, no advertising SDKs, no automatic crash uploads.
  • Voice recognition runs on-device by default; any vendor fallback asks first.
  • Optional device-to-device sync is end-to-end encrypted — the relay only ever sees ciphertext.

The privacy policy documents local storage, permissions, on-device AI, and the end-to-end encrypted sync design.

Own your data

  • Data inventory screen: see what is stored, every permission, and every access.
  • Export your whole graph as an archive; restore it on a new device.
  • Automatic local encrypted backup with a 12-word recovery phrase.
  • Full deletion with crypto-erase — gone means gone.

Support readiness

  • Use the Google Play listing for installation, updates, and the current support contact.
  • Include device model, Android version, and exact steps to reproduce the issue.

  • The in-app Diagnostics screen can export a privacy-scrubbed report bundle you control.
