Migraine Journal ("the App") is designed and operated by Mohamed Hosam ("I," "me," or "the developer"). This policy explains how the App handles your information.

The short version: your migraine data stays on your device and in your private iCloud. I never see it, sell it, or share it. The App collects a small amount of anonymous usage data — never your health information — to help me understand how it's used and improve it. No ads, no tracking across apps or websites.

What the App stores

When you use Migraine Journal, the App stores the following information locally on your iPhone:

• Migraine entries (date, severity rating 0–10, pain locations, symptoms, possible triggers, sleep hours, stress level, notes you type)
• Daily check-ins (the calendar days you marked "All clear today")
• Medication logs (medication name you type, whether it helped)
• Custom symptoms and custom triggers you create
• Disability assessment answers and scores, if you take an in-app assessment
• App settings (your daily reminder time, onboarding completion status)

The App does not collect your name, email address, phone number, contacts, photos, browsing history, advertising identifier, or any other personal information beyond what you explicitly enter into the journal. Everything in the list above stays private to you (see "Where your data lives").

Separately, the App collects a small amount of anonymous usage data — described in "Anonymous usage data" below — which never includes any of your health information.

Where your data lives

On your device. All entries are stored locally using Apple's SwiftData framework. The data file lives in the App's sandboxed storage on your iPhone.

In your private iCloud, if you're signed into iCloud. The App uses Apple CloudKit's private database to sync your entries and check-ins across your own Apple devices (iPhone, iPad, Mac) that are signed into the same Apple ID. CloudKit's private database is encrypted and accessible only to you. I do not have access to it. Apple's CloudKit infrastructure is the only third party that touches this data, and only as a sync mechanism, not as a recipient.

If you are not signed into iCloud, the App works entirely offline and stores everything only on the device you're using.
