Privacy Policy

Effective date: February 22, 2026

1. Introduction

This Privacy Policy describes how Compass (the "App"), collects, uses, and shares information when you use the App. By using Compass, you agree to the practices described in this policy.

2. Information We Collect

a) Sensor Data (on-device only)

The App accesses the following device sensors to provide compass and level functionality:

All sensor data is processed entirely on-device and is never transmitted, stored, or shared.

b) Approximate Location (on-device only)

The App may request approximate location permission (ACCESS_COARSE_LOCATION) to calculate True North (magnetic declination correction) and determine sun position. This permission is optional — the App works without it using magnetic north instead.

c) Precise Location (on-device only)

The App may request precise location permission (ACCESS_FINE_LOCATION) to display your altitude in meters and feet. This permission is entirely optional and is only requested when you choose to enable altitude display. The App continues to work fully without it.

All location data (both approximate and precise) is processed entirely on-device and is never transmitted or shared by the App.

d) Data Collected by Third-Party SDKs

The App integrates the following third-party services that may collect data automatically:

e) Locally Stored Preferences

The App stores a single preference (keep_screen_on) on your device using SharedPreferences. This value is never transmitted off the device.

3. How We Use Information

4. Third-Party Services

The third-party services integrated into the App have their own privacy policies governing the data they collect. We encourage you to review them:

5. GDPR — Users in the EEA

If you are located in the European Economic Area (EEA), the following applies:

6. Children's Privacy

The App is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us so we can take appropriate action.

7. Data Retention & Security

The App itself does not transmit or store personal data on any server. Data collected by third-party SDKs (Firebase Analytics, Crashlytics, AdMob) is retained according to Google's data retention policies. We rely on Google's infrastructure security measures to protect data collected by these services.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated effective date. We encourage you to review this policy periodically.
