Migralog

Privacy Policy

Effective date: 20 August 2026

The short version: Migralog does not collect your data. Everything you log stays on your iPhone. There are no accounts, no analytics, no third-party SDKs, and the app requests no permissions. Your migraine and headache data never leaves your device unless you choose to export and share it.

Who we are

Migralog ("the app") is published by App Harbour ApS ("we", "us"). This policy explains how the app handles information. If you have any questions, contact us at info@appharbour.com.

Data we collect

None. Migralog does not collect, transmit, or store your personal information on our servers. We operate no servers that receive your data because there are none to receive it.

Data you create in the app

When you log an attack, the details you enter — start time, intensity, duration, triggers, symptoms, medication, and notes — are stored locally on your device only. This information:

No account required

Migralog has no sign-up, no login, and no user accounts. We do not ask for your name, email, or any identifier to use the app.

No analytics or third-party SDKs

The app contains no analytics tools, no advertising networks, no crash-reporting services, and no third-party software development kits that would collect or transmit information about you or your usage.

Permissions

Migralog requests no device permissions. It does not access your camera, microphone, contacts, location, photos, or health databases.

Exporting and sharing reports

Premium lets you generate a doctor-ready PDF of your logs. This PDF is created on your device. When you use the iOS share sheet to send it (for example by email or message), the data goes only where you direct it. Once shared, the recipient and any service you send it through handle the file under their own terms — please share thoughtfully.

Subscriptions and the App Store

Purchases and subscriptions are processed by Apple through the App Store using your Apple ID. We never see or receive your payment details. Apple's handling of that information is governed by Apple's Privacy Policy.

Children's privacy

Because Migralog collects no data at all, it does not knowingly collect information from children or anyone else.

Not medical advice

Migralog is a self-tracking tool and is not a medical device. It does not provide medical advice, diagnosis, or treatment. Consult a qualified healthcare professional about your health.

Changes to this policy

If we update this policy, we will revise the effective date above and post the new version on this page.
