Privacy Policy — Kairo Focus Timer

Last updated: February 2026

The Short Version

Kairo collects zero data. No personal information, no usage analytics, no crash reports, no telemetry. Everything stays on your device. There is no server. There is no cloud. There is nothing to breach because we have nothing to store.

Data Collection

Kairo does not collect, store, transmit, or process any personal data. Specifically:

No personal information is collected (name, email, phone number, etc.)
No usage data or analytics are collected
No crash reports are sent
No device identifiers are tracked
No location data is accessed or stored
No third-party SDKs or analytics frameworks are included
No advertising networks are integrated
No data is shared with any third party

Device Permissions

Kairo requests the following permissions, all of which are optional:

Motion & Fitness

Used solely to detect phone pickups during active focus sessions (the Focus Shield feature). Motion data is processed in real-time on your device and never stored or transmitted. If you deny this permission, the Focus Shield feature will use app lifecycle events instead of motion detection.

Calendar

Optional. If granted, allows you to schedule focus sessions on your iOS Calendar. Calendar data is read/written locally through the system Calendar framework. No calendar data leaves your device.

Notifications

Optional. Used for session reminders, completion alerts, and streak notifications. All notifications are generated locally on-device.

Data Storage

All app data — focus sessions, scores, streaks, settings, and preferences — is stored locally on your device using Core Data and UserDefaults. This data is:

Stored only on your device
Protected by iOS data protection
Included in your encrypted iCloud/iTunes backups (if you have those enabled)
Permanently deleted when you uninstall the app

No Server Component

Kairo has no backend server. The app makes no network requests. There is no API, no database, no cloud storage. The app functions entirely offline.

In-App Purchases

Kairo offers an optional Pro upgrade via Apple's In-App Purchase system. All purchase processing is handled entirely by Apple through StoreKit. Apex Digital does not receive, store, or have access to any payment information.

Children's Privacy

Kairo does not knowingly collect any data from anyone, including children under 13. Since no data is collected at all, COPPA compliance is inherent in our design.

Changes to This Policy

If we ever change this privacy policy, we will update this page. However, our commitment to zero data collection is fundamental to Kairo's design and is unlikely to change.
