Privacy Policy

Privacy Policy

Last updated: November 2025

🔒 Your Privacy Matters: All your migraine data stays on your device. We don't collect, store, or share any personal health information.

Overview

Migraine Diary ("the App") is committed to protecting your privacy. This policy explains how we handle your data when you use our app.

Data Storage

All migraine entries, pain levels, triggers, and medication logs are stored locally on your device using SQLite database. Your data is:

  • Never uploaded to external servers
  • Never shared with third parties
  • Never accessible to us or anyone else
  • Completely under your control

Analytics & Advertising

The free version of the App includes advertisements provided by Google AdMob and basic analytics through Firebase Analytics. These services may collect:

  • Device information (model, OS version, screen size)
  • App usage statistics (screens viewed, session duration)
  • Anonymous identifiers for advertising purposes

When you purchase the ad-free version, all advertising services are disabled.

Third-Party Services

The App uses the following third-party services:

Health Data

Migraine Diary stores health-related information including:

  • Pain levels (0-10 scale)
  • Migraine triggers
  • Medication usage
  • Timestamps of migraine episodes

This sensitive health data is stored exclusively on your device and is never transmitted to any server.

Data Retention

Since all data is stored locally on your device:

  • Data persists as long as you keep the app installed
  • Deleting the app removes all your data permanently
  • We have no ability to recover deleted data

Children's Privacy

The App does not knowingly collect any personal information from children under 13. Since all data is stored locally and we don't operate servers, there is no data collection infrastructure.

Your Rights

You have complete control over your data:

  • View, edit, or delete any migraine entry
  • Clear all data in Settings
  • Uninstall the app to permanently remove all data

Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
