Privacy Policy

Last updated: October 14, 2026

This English translation is provided for convenience; if it differs from the Chinese version, the Chinese version prevails.

This policy explains how gugu (the "App") collects, uses, and protects your personal information. By using the App, you agree to this policy.

1. Information we collect

• Account information: When you sign in with email or a Google account, we collect your email address and (when you sign in with Google) your basic Google profile (name, avatar).
• Usage data: The sessions, messages, and related content you create while using the App, used to provide and improve the service.
• Technical information: Information necessary to keep your account secure, such as device type and sign-in time.

2. How we use information

• To verify your identity and provide sign-in and core features
• To save and sync your sessions and settings
• To keep your account and the service secure and to troubleshoot issues

3. Storage and security

Your data is stored in the backend service we use (based on Supabase), and all transmission is encrypted with HTTPS. We take reasonable technical and administrative measures to protect your data.

4. Third-party services

When you sign in with Google, authentication is provided by Google and is subject to Google's privacy policy. We obtain only the basic profile described above and do not access sensitive data such as your Gmail or Google Drive.

5. What we will not do

We will not sell your personal information, nor use it for purposes unrelated to the App.

When models are called through gugu, we do not store the content you send to the model or the model's responses; we record only the number of calls, token counts, and duration needed for billing. We do not sell or transfer any of your data.

6. Your rights

You may access, correct, or delete your account and data at any time. To delete your account or if you have any questions, contact yiheyang1@gmail.com.

7. Policy updates

This policy may be updated from time to time; material changes will be published on this page.
