Privacy Policy

Last Updated: November 12, 2025

Thank you for using Habit Flint ("we," "us," or "our"). This Privacy Policy is designed to help you understand how we collect, use, and safeguard the information you provide to us when you use our mobile application (the "App").

1. Information We Collect

We believe in collecting only the data necessary to provide you with a great experience. All data is stored locally on your device.

  • Habit Data: This includes the information you provide directly, such as the names of your habits, goals, notes, and schedules. This data stays on your device and is not sent to our servers.
  • Biometric Data (Face ID): Our App uses Apple's Face ID for authentication. We do not collect, see, or store your Face ID data. The entire authentication process is handled securely by Apple's system on your device. Our App only receives a success or failure notification to grant or deny access.

We do not collect personal information that can directly identify you, such as your name, email address, or location.

2. How We Use Your Information

Your information is used solely for the following purposes:

  • To Provide and Maintain the App: To save your habits, track your progress, and deliver the core features of the App directly on your device.
  • To Secure Your Data: To use Face ID to protect your habit data within the App from unauthorized access.

3. Data Storage and Security

All your data is stored locally on your device. We do not use external servers to store your habit data. This means you have full control over your information. If you delete the app, your data will be removed as well (unless you have a device backup).

4. Data Sharing

We do not sell, trade, or otherwise transfer your personal information to any third parties. Because your data is stored locally on your device, we do not have access to it.

5. Children's Privacy

Our App is not intended for children under the age of 13, and we do not knowingly collect any personal information from them.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by updating this page. You are advised to review this Privacy Policy periodically for any changes.
