## What is Migraine Logger?

Migraine Logger is a simple, private way to track migraines.

I originally built it for my daughter. I wanted something easy enough for a kid to use, private enough to trust, and useful enough to bring to a doctor’s appointment. No account. No ads. No tracking. Just a clean log on your phone.

WHAT YOU CAN DO
• Log a migraine in seconds
Choose the time, select the severity — Mild, Bad, or Severe — add an optional note, and tap Log.

• See patterns over time
View your history in a calendar heatmap color-coded by severity. Filter by the last 7 days, month, 3 months, year, or all time.

• Get a simple daily check-in
Optionally turn on a 7 PM reminder that asks: “Did you have a migraine today?” You can answer Yes or No right from the notification.

• Back up to your own iCloud
Your data is encrypted on your device before it leaves it. The backup lives in your iCloud, not on my server.

• Personalize the app
Choose from 12 accent colors, switch between light and dark mode, or use a photo from your library as a wallpaper.

• Export your log
Unlock PDF and CSV export with a one-time purchase. Share a filtered report by date range for appointments, records, or personal tracking.

PRIVACY
• No account required
• No ads
• No analytics or tracking SDKs
• No network requests except optional iCloud backup
• Backup is AES-256 encrypted with a key stored only in your device’s Keychain
• Photo library access is used only for optional wallpaper images, which stay on your device
