Migraine Log - Headache Diary · Last updated: July 11, 2026
Your privacy matters, especially when it comes to health information. Migraine Log is designed so that your data stays on your device and under your control. This policy explains what we do — and do not — collect.
We do not collect, transmit, sell, or share your personal data. The app has no account, no login, and no analytics or advertising trackers. Everything you log lives on your device.
None. Migraine Log does not require an account and does not ask for your name, email, or any personal identifier. The migraine and headache entries you create — including intensity, pain locations, symptoms, aura, triggers, medications, relief ratings, and notes — are stored only in a private database on your device.
Your entries are saved locally using Apple's on-device database. If you have iCloud or device backups enabled, your data may be included in your own encrypted backup under your Apple Account. We have no access to those backups.
Subscriptions and the one-time Lifetime purchase are processed by Apple through the App Store. We never see or store your payment information. Apple provides us only anonymous, aggregate sales and subscription statistics, which cannot identify you.
PDF reports are generated entirely on your device. A report leaves your device only if you choose to share it (for example, by emailing it to your doctor). We do not receive a copy.
The app does not integrate any third-party analytics, advertising, or tracking services. No data is sent to us or to anyone else.
The app is not directed at children under 13 and does not knowingly collect information from them.
You can delete any single entry, or erase all of your data at any time from Settings → Delete All Data inside the app. Deleting the app also removes its on-device data.
If this policy changes, we will update the date at the top of this page.
