Privacy Policy

Last updated: June 2025

This Privacy Policy applies to all iOS apps developed by erzuo studio, including but not limited to OOTD Diary. Please read carefully before use.

1. Information We Collect

We collect only the minimum information necessary to provide our services:

  • Photos you upload (used only during AI analysis and not permanently stored on our servers)
  • In-app content data (rating history, user preferences) stored locally on your device
  • Crash logs and anonymous usage statistics to improve app stability (no personally identifiable information)

2. How We Use Information

Information collected is used solely to provide AI analysis features, optimize app experience, and resolve technical issues. We do not sell, rent, or share your information with any third party for marketing purposes.

3. Photo Data

Photos you upload are transmitted via encrypted connection to third-party AI providers (such as OpenAI) for analysis. They are not retained on our servers after processing. Please avoid uploading images containing other people's faces or sensitive information.

4. Third-Party Services

We use the following third-party services, each with their own independent privacy policies:

  • OpenAI API — AI analysis capabilities
  • RevenueCat — Subscription management
  • Apple App Store — App distribution and payments

5. Data Security

All network transmissions use HTTPS encryption. Local data is stored in the secure sandbox environment provided by iOS. We do not store your payment information — all payments are processed by Apple App Store.

6. Your Rights

You can delete the app at any time to clear local data on your device. To request deletion of any data associated with you, please contact us using the details below.

7. Children's Privacy

Our apps are not directed at children under the age of 13, and we do not knowingly collect personal information from children.
