Mobile ZG — Privacy Policy

Thank you for using Mobile ZG. We value your privacy. This policy explains what information we collect, how we use it, and how we protect it.

1. What We Collect

You do not need to create an account, and we do not collect your name, phone number, or email. We collect:

• Anonymous device ID — a random identifier generated on your device, used to link your comments, favorites, open events, and messages to this device. It cannot identify you personally.
• Content you create — comments (text or voice), favorites, and messages sent to the author.
• Usage statistics — app open time/count, for statistics only.
• Media — images, videos, and audio you upload.
• Microphone — used only when you record a voice comment; uploads only after you confirm.

2. How We Use It

To display diaries, save your comments/favorites/messages, and generate usage statistics. Content is stored on our cloud service (Supabase) for sync and display.

3. Storage & Third Parties

Data and media are stored on Supabase cloud, encrypted in transit (HTTPS). We do not run ads or sell your data. We may disclose information when required by law or for security.

4. Retention & Your Rights

Data is kept as needed to provide the service. Since there's no account, content is tied to your anonymous device ID. You can delete your own comments in the app, or contact the author to delete data related to your device.

5. Children

This app is for general users, not directed at children under 13, and does not knowingly collect children's information.

6. Security

We use reasonable technical and administrative measures (HTTPS, access control) to protect your data.

7. Policy Changes

This policy may be updated; significant changes will be announced in the app or on this page.

8. Contact
