Privacy Policy

Nook App  ·  Last updated: March 2026

Nook ("we", "our", or "us") is committed to protecting your privacy. This policy explains what information we collect, how we use it, and your rights.

1. Information We Collect

Nook is designed to collect as little data as possible.

• No account required. You do not need to register or provide personal information to use the app.
• Local storage only. Your revealed artifacts, favorites, and completed reveal mechanics are stored locally on your device using AsyncStorage. This data never leaves your device.
• Purchase information. If you purchase Nook Premium, the transaction is processed by Apple through the App Store. We use RevenueCat to manage subscription status. RevenueCat receives a randomly generated anonymous user ID and your purchase receipt from Apple — no name, email, or contact information is shared.

2. Information We Do Not Collect

• Name, email address, or any contact information
• Location data
• Device identifiers or advertising IDs
• Usage analytics or crash reports
• Any data from your camera, microphone, or photo library

3. Third-Party Services

Nook uses the following third-party services:

• RevenueCat – subscription and purchase management. See their privacy policy at revenuecat.com/privacy.
• Art Institute of Chicago API – public artwork data served through our backend. No user data is sent to this API.

4. Data Storage and Security

All personal preferences are stored locally on your device. Our backend server (used to fetch artwork content) does not store any user-identifiable information and does not use cookies or tracking.

5. Children's Privacy

Nook does not knowingly collect any information from children under the age of 13.

6. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by the "Last updated" date above. Continued use of the app after changes constitutes acceptance of the updated policy.
