Privacy Policy

Local-Only Health Data

Migraine Tracker stores all of your personal health data locally on your device using SQLite. We do not collect, transmit, or store your health information on our servers. Health data you log may include migraine attacks, symptoms, pain locations, triggers, medications, sleep hours, stress levels, and menstrual cycle information.

No Health Analytics or Advertising

We do not use analytics tools, advertising identifiers, or third-party trackers to monitor your health data or behavior. Your health data stays on your device and under your control.

Third-Party Services

We use the following services that may process limited, non-health data:

• RevenueCat — Handles Pro subscription purchases. RevenueCat receives transaction and purchase identifiers, not your health data.
• Firebase Crashlytics — Collects crash reports and basic device information to help us fix bugs. Crashlytics does not access your health logs.
• Weather data provider — If you grant permission, your approximate location is used once to fetch local weather data. Location data is not stored or shared beyond this request.

Data Security

Your data is stored locally on your device. You can optionally enable biometric or device PIN lock in the app settings for an additional layer of protection.

Data Retention

Your health data is retained only on your device until you choose to delete it from within the app or uninstall the app. We do not retain copies on our servers.

Your Rights

You can export or delete your data at any time from within the app. If you delete the app, all locally stored data is removed from your device.

Children's Privacy

This app is not intended for children under the age of 13. We do not knowingly collect personal data from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
