Privacy Policy — Aqua Haven
Effective date: 26 October 2026 · App: Aqua Haven / Vườn Nước: Nuôi Cá Thư Giãn (Android, com.mati.aquahaven)
In short: Aqua Haven has no accounts and never asks for your name, email, phone number, contacts or precise location. Your game progress is stored on your device. Some Google services built into the game (ads, purchases, usage statistics, crash reports, optional cloud save) process limited device and usage data as described below. We do not sell your data.
1. Who we are
Aqua Haven is developed and published by an individual developer under the brand Mati ("Mati Studios", "we", "us"), who is the controller of the data described in this policy. Contact: mati.game.vn@gmail.com.
2. Data stored only on your device
- Game progress: fish, ponds, decorations, coins and pearls, album, quests, events and settings (language, volume). Saved as files in the app's private storage.
- Birthday (optional): from your second day of play the game may ask once for your birthday, day and month only (no year), to give you an in-game gift on that day. You can skip it. It is not used to determine your age, stays on your device and is not sent to us or to any third party.
- In-game photos and GIFs: pictures you capture of your pond are saved in the app's private folder on your device.
- Purchase entitlements: a local record of items you bought (the receipt itself is held by Google Play).
Mati does not operate its own servers and does not receive this data.
3. Data processed by third-party services
| Service (provider) | Purpose | Data that may be processed | Policy |
|---|---|---|---|
| Google Play Billing (Google), via the Unity IAP library | In-app purchases and restoring purchases | Purchase history, order ID. Payments are processed by Google Play; receipts are verified on the device and are not sent to any intermediary server (no RevenueCat). We never see your card. | Google Privacy Policy |
| Google AdMob (Google) | Optional rewarded ads and interstitial ads | Advertising ID, IP address (approximate location), device and app information, ad interactions | How Google uses data from apps that use its services |
| Google Play Games Services — Saved Games (Google) | Optional cloud backup of your progress | A snapshot of your game progress (same content as the local save), save time and level, linked to your Play Games profile | Google Privacy Policy |
| Firebase Analytics (Google) | Understanding how the game is played (e.g. tutorial completion, returning on later days, pond unlocks, ads watched, purchases) to improve game balance | App instance ID, in-game events, device model, OS version, language, country / approximate location derived from IP | Privacy and Security in Firebase |
| Firebase Crashlytics (Google) | Finding and fixing crashes | Crash traces, device state at the time of the crash, installation ID | Privacy and Security in Firebase |
| Firebase Remote Config (Google) | Adjusting game settings (prices, timers) without an app update | Installation ID, app version, device language and country | Privacy and Security in Firebase |
We do not share data with anyone other than these providers, who process it to deliver their services. Data is encrypted in transit (HTTPS).
4. Ads and your choices
Rewarded ads are always optional. Where required by law (for example in the EEA, UK and Switzerland) the game asks for your consent through Google's consent tool before showing personalised ads, and you can change your choice later in the game's settings. You can reset or delete your Advertising ID, or opt out of personalised ads, in your device's Google settings. Buying "Remove Ads" turns off interstitial ads.
5. Notifications
The game can show local notifications (for example when an egg is about to hatch). They are scheduled on your device and send no data. You can turn them off in the game's settings or in Android settings.
6. Device permissions
Internet and network state (ads, purchases, statistics, cloud save), notifications (Android 13+, you can refuse), and Advertising ID. The game does not request camera, microphone, contacts, location or shared-storage permissions.
7. Retention and deletion
- On your device: kept until you use Settings → Delete data in the game (erases progress, birthday and other game files; keeps language/volume settings and purchase entitlements) or uninstall the app (erases everything, including photos).
- Cloud save: kept in your Google Play Games account until you delete it from the Play Games settings.
- Firebase Analytics: event-level data is deleted automatically after the retention period we set (14 months). Crashlytics: crash reports are kept for up to 90 days.
- AdMob and Google Play: retained according to Google's policies.
To ask us to delete statistics or crash data linked to your device, see Delete your data. We reply within 30 days.
8. Children
Aqua Haven is intended for users aged 13 and over and is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe a child has provided data, contact us and we will delete it.
9. Your rights
Depending on where you live (for example under the EU/UK GDPR or Vietnam's personal data protection law), you may have the right to access, correct or delete your data, to restrict or object to processing, to withdraw consent at any time, and to complain to a data protection authority. Email us to exercise these rights.
10. International transfers
Google's services may process data on servers outside your country, under the safeguards described in Google's policies.
11. Changes
We will post changes on this page and update the effective date above.
