Kairo help guide

Privacy and security

See what stays on your phone, when data can leave Kairo, how rotating Bluetooth presence works, and what encrypted backup deliberately excludes.

Private by default, not disconnected from reality

Kairo’s core experience works without internet, but it does not claim the app can never use a network. Internet may be used for update checks and optional features you explicitly enable, such as Google Drive backup. Opening a coordinate in Maps or sharing a poster also hands selected data to another app after your action.

Local-first core

Connections, moments, Timeline, Radar, notes, favorites, media links, and Memory Books are stored locally by default.

Rotating presence

Kairo emits short-lived presence identifiers rather than broadcasting your stable profile or name in every Bluetooth packet.

App lock

Require the device credential or biometric before opening Kairo. Android controls whether notification previews remain visible.

Intentional sharing

Data leaves through a feature you choose: backup, poster sharing, opening Maps, diagnostics, or opt-in Around visibility.

Bluetooth identity

Trusted connections exchange private presence material in person. The BLE advertisement contains a compact rotating token under Kairo’s fixed service identifier. A receiver computes expected tokens for its trusted connections and matches locally. Names, notes, memories, coordinates, and photos are not placed in the presence advertisement.

Backup boundaries

Backup archives are encrypted on the device and stored in Google Drive’s private app-data area. Portable history is separated from device trust: the archive can restore memories but cannot impersonate an already trusted phone. The recovery code controls decryption on a new installation.

Control and deletion

  • Pause a connection without deleting its Timeline.
  • Remove individual media attachments or a Memory Book background.
  • Delete individual backup generations or every Kairo Drive backup.
  • Disable Around visibility, location tagging, Flare requests, or automatic backup independently.
