Brain Bank Privacy Policy

Introduction

Welcome to Brain Bank! This Privacy Policy explains how Brain Bank ("we", "our", or "us") collects, uses, and discloses information about you when you use our mobile application (the "App").

We are committed to protecting your privacy, especially given the educational nature of our App. We prioritize keeping your data on your device and minimizing any data collection.

Data Collection and Use

1. Personal Information

We do not collect, store, or share your personal information (such as your name, address, or phone number) on our servers.

• Sign In with Apple: If you choose to sign in using Apple, we may receive your name and email address to create your account. This information is processed in accordance with Apple's privacy policies and is used solely for authentication and account management.

2. Usage and Progress Data

Brain Bank is designed to be privacy-first.

• Local Storage: Your math practice history, quest progress, earned coins, and unlocked rewards are stored locally on your device using Apple's SwiftData technology.
• No Cloud Sync (Default): Unless explicitly enabled (e.g., via iCloud backups managed by Apple), your progress data does not leave your device.

3. Camera and Photos

If the App requests access to your Camera or Photo Library (e.g., for setting a profile picture or specific "Heirloom" features), this data remains on your device and is not uploaded to our servers.

4. Microphone

If the App requests access to your Microphone (e.g., for voice-enabled practice), audio data is processed locally.

Third-Party Services

We do not sell your data. We use the following third-party services solely to provide the App's functionality:

• Apple Services: For authentication, local storage, and image generation.

Children's Privacy

Brain Bank is an educational app suitable for users of all ages. We do not knowingly collect personal information from children under 13 without parental consent. Because our app primarily stores data locally, the risk to children's privacy is minimized.

Data Security

We implement reasonable security measures to protect your information. However, please be aware that no method of transmission over the internet or electronic storage is completely secure.

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 Privacy Policy on this page and updating the "Last Updated" date.
