Aqua Tank is a 3D ecosystem aquarium that runs inside your browser. Rendering and interaction happen on your device. We (the developers) operate no first-party business server that collects tank data, and we do not upload your layout.
1. What we process on your device
- Tank layout and species placement (stored in
chrome.storage.local) - Preferences: UI language, float toggle, ambient sound, night mode, and similar settings
- Optional unlock-status cache (Pro)
- Procedural audio synthesized on-device — no external audio downloads
2. What we do not collect
- Account registration (you can use the extension without signing in)
- Cloud sync, telemetry, advertising identifiers, or crash reporting
- Sending tank state or page content to a developer server (we have none)
3. Permissions
| Permission | Why |
|---|---|
storage | Save layout, preferences, and unlock cache (all local only) |
| Host matches (http/https content script) | Inject an optional top-right float entry on ordinary pages; the float never reads or uploads page content |
4. Network
- Core aquarium rendering and care work offline
- If a third-party payment unlock is connected later, it is only contacted when you start a purchase; see the extension release notes
- No analytics, ads, or unrelated CDN fetches
5. Storage and your rights
All related data stays on your device. Delete it by clearing extension data or uninstalling Aqua Tank. Screenshots saved to disk are yours to keep.
6. Children’s privacy
This extension is not directed to children under 13. We do not knowingly collect personal information from children.
7. Changes
We may update this policy from time to time. Significant changes will be noted with extension releases. Please review this page periodically.
8. Contact and consent
For privacy questions, email yugakhans@gmail.com or contact the publisher listed on the Chrome Web Store item page. By installing and using Aqua Tank, you agree to this privacy policy. If you do not agree, please do not use the extension.
