English
1. Overview
Zen Stargazer (“the App”) is a mixed-reality stargazing experience for Meta Quest. This Privacy Policy explains what information the App processes, how it is used, and how you can request deletion. We do not sell personal information.
2. Information we process
| Type | What | Where it stays |
|---|
| App preferences | Language choice, constellation display options, and similar settings | Stored only on your device |
| Observer site | City / place name and coordinates you select to compute the sky | Stored only on your device |
| Captured images (optional) | Sky images / photos you choose to save may go to the device photo library | On your device; we do not upload them to our servers |
| Passthrough / camera | Used so you can see your room with the sky overlay | Processed on-device; we do not receive or store room video on our servers |
| Hand / controller tracking | Used for pointing and UI | Processed on-device |
We do not require an account. We do not operate our own analytics, advertising, or cloud login for this App. We do not intentionally collect names, email addresses, phone numbers, or payment card data inside the App.
Meta / platform data: Meta may process device, store, and usage information under Meta’s own policies when you use Meta Quest and the Meta Horizon Store. That processing is controlled by Meta, not by this Privacy Policy.
3. How we use information
On-device settings and observer location are used only to remember preferences, show a sky for the place and time you choose, and improve usability. Optional saved images are for your personal keeping or sharing by you.
4. Sharing
We do not sell or rent your personal information. We do not share App preference or observer-site data with third-party advertisers. Platform features operate under Meta’s and the device OS terms.
5. Retention
Local preferences and observer-site data remain until you change them, clear app data, or uninstall. Photos you save remain until you delete them from your gallery.
6. Children’s privacy
The App is a general-audience educational / lifestyle experience. We do not knowingly collect personal information from children. Contact us if you believe a child provided personal information via our website, and we will delete it where applicable.
7. Your choices and deletion
- Change or clear language / location settings in the App
- Delete saved photos from your device gallery
- Clear App storage or uninstall the App to remove local App data
To request deletion of any personal information you believe we hold outside the device (for example a message you sent us), contact the developer below. We will respond within a reasonable time.
8. International users
The App stores the data described above locally on your device. Correspondence via website or email may be processed where we operate (including Taiwan).
9. Changes
We may update this Privacy Policy from time to time. The “Last updated” date will change when we do. Continued use after an update means you accept the revised policy.
