For any privacy question, email hello@glintside.com.

2 What the app does

Migraine Tally is a private migraine and headache diary. You can log attacks, pain, medicines, symptoms, triggers, notes, doctor visits and your own custom trackers. You can also make a PDF report to take to your doctor.

3 We don't collect your data

• There is no account and no sign-in.
• There are no Glintside servers. The app has no internet permission.
• There are no ads, no analytics, no crash reporting and no tracking.
• Glintside never receives, sees or stores any of your diary data.

4 Where your data is kept

Your diary is kept only on your own phone and watch, in the app's private storage. Uninstalling the app deletes it.

You can edit or delete any entry or attack at any time.

5 Your phone and watch

Your phone and watch exchange diary entries directly, over the Wear OS connection between your own devices (Bluetooth or local Wi-Fi). The app does not store anything in Google's cloud to do this.

6 Health Connect (optional, Pro)

If you choose to connect Health Connect, the app reads your sleep and menstrual cycle data only to show patterns on screen.

• Access is read-only. The app reads this data when you open the Patterns screen.
• This data is never copied into your diary, written back to Health Connect, shared or sent anywhere.
• You can revoke access at any time in Health Connect settings.

The use of information received from Health Connect will adhere to the Health Connect Permissions policy, including the Limited Use requirements.

7 Barometer (optional, Pro)

If your phone has a pressure sensor and you turn this feature on, the app records air pressure on your device to show a "pressure drop" pattern. It does not use your location.

8 Purchases

Pro is a one-time in-app purchase, handled entirely by Google Play. Glintside receives no payment or card details.

Google's processing for Google Play is covered by the Google Privacy Policy. Google Play's billing library may send its own diagnostic data to Google.

9 Sharing is always your choice

• PDF reports, CSV exports and backup files are created only when you ask for them, and go only where you send or save them.
• Backup files are encrypted with a passphrase you choose. Glintside never knows your passphrase.
• Android's automatic cloud backup is off by default. It only turns on if you opt in.

10 Permissions and why the app uses them

• Notifications: for optional reminders, which are off by default.
• Biometric (fingerprint or face): for the optional app lock. Android handles this, and the app never sees your fingerprint or face data.
• Vibration: so the app can vibrate your phone or watch.
• Background work: to deliver your reminders.

The app does not ask for location, contacts, camera, microphone or file storage permissions.

11 Not medical advice

Migraine Tally is a diary. It does not diagnose or treat any condition.

12 Children

The app is not directed at children under 13.

13 Changes to this policy

If we update this policy, we will post the new version on this page with a new effective date.
