Privacy Policy

Last updated: July 12, 2026

1. Information We Collect

ShiBei is designed with privacy-first principles. We do not collect any personal information. All data you create (cards, tags, notes) is stored locally on your device only.

2. How We Use Your Information

Since we do not collect any personal information, there is no data usage beyond what happens locally on your device. Your data stays on your device and is never transmitted to our servers.

3. AI Features

When you use AI-powered features (summarization, question generation), the content you provide is sent to a third-party AI API service. This data is processed temporarily and is not stored by us. We recommend not including sensitive personal information in the content you submit to AI features.

4. Third-Party Services

Our app uses the following third-party services:

• AI API Provider - Processes text content for AI summarization and question generation. Data is transmitted securely and not stored.
• Apple In-App Purchase - Processes membership payments. Apple handles all payment data according to their own privacy policy.

5. Data Security

Since all data is stored locally on your device, you are in full control. You can export, backup, or delete your data at any time through the app settings.

6. Your Rights

You have the right to:

• Access all your data (it's on your device)
• Export your data at any time
