Privacy Policy — Water Reminder AI
Publisher: Minno Technology · Effective date: November 4, 2026
Water Reminder AI ("the app") helps you track how much water you drink and reminds you to drink. This policy explains what data the app handles, why, and the choices you have. The app works offline and does not require an account.
1. Data that stays on your device
Your water intake log, daily goal, reminder schedule, profile inputs you enter (such as weight or activity level, used only to suggest a goal), language, theme and consent choices are stored only on your device. We do not upload them to our servers, and we do not operate an account system. Uninstalling the app deletes this data. You can also reset it in the app's Settings.
Reminders are local notifications scheduled on your device; no notification server is involved.
2. Advertising (Google AdMob)
The free version shows ads served by Google AdMob. To deliver and measure ads and to prevent fraud, Google may collect:
- Device advertising identifier (Android Advertising ID / Apple IDFA, the latter only if you allow tracking),
- IP address, coarse location derived from it, device and app information,
- Ad interaction data (impressions, clicks) and diagnostics.
In the European Economic Area, the UK and Switzerland, and where otherwise required, the app asks for your consent with Google's User Messaging Platform before personalized ads are shown. On iOS, the app asks for permission via App Tracking Transparency only if you choose personalized ads; if you decline, you still receive non-personalized ads. You can change your choices any time in Settings → Privacy. See How Google uses information from apps that use its services.
You can also reset or delete your advertising ID in your device settings.
3. Purchases
An optional one-time "Premium" purchase removes ads. Payments are processed by Google Play or the Apple App Store; we never receive your card details. The app only receives a confirmation that the purchase is valid, so it can unlock Premium and restore it later.
4. Analytics
The app does not send usage analytics to us or to third-party analytics services. Basic diagnostics are kept on your device only.
5. Summary
| Data | Where | Purpose | Shared with |
|---|---|---|---|
| Water log, goals, reminders, settings | Your device only | App functionality | No one |
| Advertising ID, IP, device info, ad interactions | Collected by Google AdMob SDK | Advertising, analytics of ads, fraud prevention | |
| Purchase confirmation | Google Play / App Store | Unlock and restore Premium | Google / Apple |
6. Children
The app is not directed to children under 13 (or the minimum age in your country) and we do not knowingly collect personal data from children.
7. Your rights
Because your app data stays on your device, you control it directly: view, edit or delete it in the app, or uninstall the app. For data processed by Google for advertising, you can use the consent options in the app, your device's ad settings, and Google's own privacy tools. Depending on where you live (for example under the GDPR or CCPA), you may have additional rights; contact us and we will help.
8. Health information
The app is a general wellness tool and does not provide medical advice. Data you enter is not shared with anyone.
9. Changes
We may update this policy. The effective date above shows the latest version; significant changes will also be noted in the app's release notes.
