Privacy policy

Your records stay
with you.

Last updated: September 27, 2026

Migraine Tracker: Capture is designed to help you record a migraine with as little effort as possible. This policy explains what the current version of the app does with your information.

What data the app stores

The app can store migraine and headache records, timestamps, optional medication entries, severity, functional impact, symptoms, and notes that you choose to add. These records are health information and are treated as private.

Where your data is stored

The iOS app uses SwiftData for local-first storage on your device. Every entry is written to your iPhone first, and the app works fully without a network connection.

If you are signed in to iCloud, your records also sync through Apple’s CloudKit to the private database of your own iCloud account, so that your history survives a new phone or a reinstall. That sync is between your devices and Apple; the records are not sent to us, we operate no server, and we cannot read them. Apple’s handling of iCloud data is covered by Apple’s own privacy policy. If you are not signed in to iCloud, or you turn iCloud off for this app in iOS Settings, the app keeps working and your records simply stay on the device.

The app still does not require an account of any kind.

Sharing and exports

Health records leave the device only when you explicitly choose to share or export them using the system share sheet. Once shared, the information is handled by the service or person you choose.

Payments and the Lifetime purchase

The app offers one optional in-app purchase, Lifetime: a one-time purchase, not a subscription, that unlocks the longer-range summaries. Capturing, viewing, and exporting your records never require it.

Lifetime is sold and processed by Apple through the App Store’s in-app purchase system (StoreKit), under your Apple Account. Apple handles the payment; we never receive or store your card or other payment details. The app asks Apple, through StoreKit, whether Lifetime is owned on your Apple Account, and remembers the answer on your device so the unlock works offline. Restoring the purchase and refunds are handled by Apple, and Apple’s handling of purchase information is covered by Apple’s own privacy policy.

Third-party services

The app uses one third-party service, RevenueCat (RevenueCat, Inc.), to keep a record of in-app purchases. We use it to confirm purchases and to see purchase and revenue totals. It is not used for advertising, and the app does not rely on it to decide whether Lifetime is unlocked.

Whether or not you buy anything, the app connects to RevenueCat when it opens and sends: a random identifier created for this installation of the app; Apple’s identifier for vendor, a device identifier that is shared only by apps from the same developer and is not the advertising identifier; and basic technical information, such as the app version, iOS version, device model, preferred languages, and App Store country. As with any internet service, RevenueCat also receives the network (IP) address the connection comes from.

If you buy or restore Lifetime, RevenueCat also receives the App Store transaction information for this app, such as the product, price, currency, and purchase date, and later whether the purchase was refunded.

The app has no accounts, so none of this is tied to your name, email address, or Apple Account. RevenueCat does not receive your migraine or headache records, times, severity, symptoms, medications, notes, or anything else you record in the app; those stay on your device and in your own iCloud account as described above. RevenueCat’s handling of information is described in RevenueCat’s privacy policy.

The app does not use product analytics, crash reporting, HealthKit, or any other third-party health-data service.

Tracking and advertising

The app does not track you. It shows no ads, contains no advertising SDK, never reads the advertising identifier (IDFA), and never asks for tracking permission. Information from the app is not combined with data from other companies’ apps or websites for advertising, and it is not sold or shared with data brokers.

Deleting your data

You can delete records using the deletion controls in the app. When iCloud sync is on, a deletion also propagates to your other devices signed in to the same iCloud account. Deleting the app removes its local data according to your device’s normal app-deletion behavior; a copy may remain in your iCloud account until you erase the app’s data from within the app or remove it in iOS Settings under iCloud. Any copy you have explicitly shared must be deleted from the destination separately.

Deleting records or the app does not remove the anonymous purchase information held by RevenueCat or Apple. If you would like the RevenueCat record for your installation deleted, email us; if you bought Lifetime, the order ID on Apple’s purchase receipt helps us find it.

Children’s privacy

The app is not directed at children under 13. We do not knowingly collect personal information from children.

Medical information

Migraine Tracker: Capture is a record-keeping tool, not a medical device. It does not diagnose conditions, provide treatment advice, or replace a clinician’s care.

Policy updates

If the app’s data practices change, this policy will be updated before or when those changes take effect. The “Last updated” date above will also change.
