This Privacy Policy describes how the mobile application MIgraine Companion ("the App") collects, uses, and protects your information. The App is owned and operated by Iuldashov Rustam Muhiddinovich ("we," "us," or "our").
By using the App, you agree to the collection and use of information in accordance with this Privacy Policy. We are committed to protecting your privacy and complying with all applicable laws, including App Store and Google Play requirements.
We only collect or access information that is necessary to provide and improve the App's functionality. All data is stored locally on your device and is not transmitted to our servers.
The types of information the App may access (with your explicit permission) include:
When you log in via Google or Apple, we receive basic profile information such as your name and email address. This is used for authentication and account identification purposes. We do not have access to your login passwords or any financial information.
You may input or record health-related information, including:
Migraine attacks
Symptoms and triggers
Medications
Related notes
This sensitive health data is stored on your device and used solely to help you track and manage your migraines.
If you choose to sync the App with wearable devices (such as a smartwatch or fitness tracker), the App may collect data from those devices (for example, heart rate or physical activity) to enrich your migraine tracking. Such data integration is done only with your consent and remains on your device.
With your permission, the App can access your device's location data. For instance, you might log the location of a migraine episode or allow the App to detect environmental factors (like weather or altitude) that could be migraine triggers. Location data is used only for providing these features to you and is not shared with us or third parties.
With your consent, the App may use your device's microphone to record voice notes about your symptoms. Any audio recorded stays on your device; we do not transmit or analyze your voice recordings on our servers.
The App may send you push notifications or alerts (for example, reminder notifications to log your daily condition or take medication). Notification preferences can be configured in the App or your device settings. We do not collect personal information through push notifications.
⚠️ Important: All the above data is stored only on your device. We do not upload or send your personal data, health records, or any logs to any server. This means that we, as the developers, cannot access your information.
We use the information available on your device solely to provide you with the App's core features and to improve your experience. Typical purposes include:
✅ Allowing you to log migraine attacks, symptoms, triggers, and notes so you can better understand your condition over time
✅ Generating visual summaries, charts, or patterns from your data to help you identify trends
✅ Personalizing reminders or notifications to support consistent tracking and medication adherence
✅ Integrating optional data from wearables (if you enable it) to enrich your personal analysis
✅ Providing therapeutic features like breathing exercises and relaxation games to help manage migraine symptoms
We do not use your data for advertising or marketing purposes. There are no third-party ads in the App, and we do not sell or disclose your data to advertising networks or data brokers.
In accordance with App Store guidelines and data privacy regulations, you have the right to delete your account and all associated personal data at any time.

You can also request account deletion by contacting us at:
📩 migrainecompanion.app@gmail.com
We will process your request within 7 business days.
We may retain anonymized and aggregated data that cannot be linked back to you for statistical purposes to improve our services.
All personal and health data used by the App is stored locally on your device. We do not operate a remote backend database that stores your migraine logs or health information.
Because of this design, you are in control of your data and can delete it at any time by:
Uninstalling the App
Using the in-app deletion tools
Because data is stored on your device, it is important that you secure your device (for example, with a passcode or biometric lock) to prevent unauthorized access. If your device is lost, stolen, or compromised, your data could be accessed by others.
If you use your device's backup features (iCloud or Google Drive), your App data may be included in those backups according to your device settings. This is managed by Apple or Google, not by us.
The App may interact with third-party services for the following purposes:
