Privacy Policy

MigraSense: Migraine Tracker — Last updated: March 20, 2026

Our commitment: MigraSense is designed with your privacy as a priority. Your health data stays on your device or in your personal iCloud account. We do not collect, sell, share, or transmit your data to any third parties.

1. Data We Collect

MigraSense collects only the data you provide directly within the app. We do not collect data automatically, nor do we use any third-party analytics, advertising, or tracking services.

a) Migraine & Health Data

Daily migraine logs (date, occurrence, and personal notes)
Trigger entries (e.g. stress, screen time, weather changes, and custom triggers you define)
Pain location data (anatomical regions such as forehead, temples, eyes, jaw, etc.)
Medication records (name, dosage, frequency, effectiveness, and pain quality before/after)
Reliever records (relief methods used, duration, and effectiveness scores)

b) Appointment Data

Doctor name, reason for visit, date/time, and reminder preferences
Local notification identifiers for appointment reminders

c) User Profile

Display name and email address (provided by you during account setup or Apple Sign-In)

d) Preferences & Settings

Appearance mode (light, dark, or automatic)
Language preference
iCloud sync preference
App lock and biometric authentication preferences

2. How Your Data Is Stored

a) On-Device Storage

All data is stored locally on your device using Apple's SwiftData framework. Your data benefits from iOS's built-in hardware encryption and device-level security protections.

b) iCloud Sync (Optional)

If you enable iCloud sync, your data is stored in your personal iCloud account via Apple's CloudKit. This data is encrypted in transit and at rest by Apple. Only you can access this data through devices signed into your Apple ID. You can disable iCloud sync at any time in the app's settings, and your data will remain on-device only.

c) Apple HealthKit (Optional)

If you enable HealthKit integration, MigraSense writes migraine headache records to the Apple Health app on your device. This data is governed by Apple's HealthKit privacy policies. MigraSense does not read data from HealthKit — it only writes migraine records with your explicit permission. You can revoke this access at any time in your device's Health settings.

3. Data We Do NOT Collect

MigraSense does not collect, access, or use:

Location or GPS data
Device identifiers or advertising IDs
Browsing history or app usage analytics
Contacts, photos, microphone, or camera data
Crash reports or diagnostics sent to third parties
Any data for advertising or marketing purposes

4. Third-Party Services

MigraSense uses only native Apple frameworks and services:

Apple StoreKit — to process in-app subscriptions and purchases. Payment information is handled entirely by Apple and is never accessible to us.
Apple CloudKit — for optional iCloud data sync, encrypted and managed by Apple.
Apple HealthKit — for optional health data integration, managed by Apple.
Apple Sign-In — for optional account authentication, managed by Apple.

We do not integrate any third-party analytics, advertising, crash reporting, or tracking SDKs.

5. Biometric Authentication

MigraSense offers an optional app lock feature using Face ID, Touch ID, or Optic ID. Biometric data is processed entirely on your device by Apple's Local Authentication framework. MigraSense never accesses, stores, or transmits your biometric data.

6. PDF Reports

MigraSense allows you to generate PDF reports summarising your migraine history. These reports are created locally on your device and are shared only when you explicitly choose to do so via the iOS share sheet. We do not have access to your exported reports.

7. Subscriptions & Payments

MigraSense offers optional subscription plans (monthly and yearly) for premium features. All payment processing is handled by Apple through the App Store. We do not collect, store, or have access to your credit card, bank account, or any payment information.

8. Data Retention & Deletion

Your data remains on your device (and optionally in your iCloud account) for as long as you use the app. To delete your data:

Delete the app — removes all locally stored data from your device.
iCloud data — can be removed via Settings > Apple ID > iCloud > Manage Storage on your device.
HealthKit data — can be deleted via the Apple Health app.

Since we do not store your data on any external servers, there is no server-side data to delete.

9. Children's Privacy

MigraSense is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided data through the app, please contact us so we can assist with its removal.

10. Security

We rely on Apple's platform-level security to protect your data, including:

iOS hardware encryption for on-device data
CloudKit encryption for iCloud-synced data
App Transport Security (ATS) for all network communications
Cryptographic transaction verification for in-app purchases
Optional biometric app lock for additional protection

11. 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 revision date. We encourage you to review this policy periodically.
