Protected note fields use application-layer encryption before local persistence and cloud sync.

Switch between Original, Graphite, Copper Glow, Blue Horizon, Evergreen, and Archive Sepia.

Rich text tools

Format notes with bold, italic, underline, lists, checklists, and color without leaving the editor flow.

Search, pin, and filter

App lock and biometrics

    Create the note, rough idea, or reminder without waiting on structure first.

    Use AI Powered assistance only when you want a stronger draft, summary, title, or reminder signal.

  3. 03

    Protect and organize

    Apply categories, reminders, app lock, and note protection without leaving the core note workflow.

  4. 04

    Read offline, sync when due

    Daily reading stays local first, including reader-mode PDF workflows, while sync timing runs in the background.

The trust layer is visible, specific, and easier to verify.

The public story now matches implementation more closely: optional controls are named, note protection is described with care, and permission-dependent behavior is explicit.

Data processing stays tied to product actions.

AI requests, reminders, billing, ads, and community links each map to a known product flow instead of hidden background collection.

Protected note fields are encrypted before sync.

Public messaging now points to application-layer protection, wrapped keys, and local security options without marketing exaggeration.

User control stays explicit.

Notifications, biometrics, AI assistance, and note deletion are described as user-enabled behaviors rather than default assumptions.

Permissions used in the current Android build Internet, network state, notifications, biometrics, exact alarms, wake lock, boot and foreground data sync support
Not requested in the current Android build Location, contacts, microphone, camera
Privacy policy status Rewritten for Google Play User Data clarity
