The short version
- You don't need an account, and we never ask for your name, email, contacts, photos or location.
- Your game progress stays on your phone. We don't run any servers that receive it.
- The app shows ads through Google AdMob. Where the law requires it (for example in the EU, EEA, UK and Switzerland), we ask for your consent before ads use your data, and you can change your choice at any time.
- Purchases are handled entirely by Google Play. We never see your payment details.
- We don't sell your personal data.

2. What data is processed, why, and on what legal basis
| Data | Purpose | Where it goes | Legal basis (GDPR) |
|---|---|---|---|
| Game progress and settings (levels, stars, coins, boosters, sound and notification settings, purchased items) | To run the game and remember your progress | Stored only on your device | Performance of our contract with you (Art. 6(1)(b)) |
| Advertising ID, IP address, device and app information (model, Android version, language), ad interactions, approximate location derived from the IP address | To show ads, limit how often you see them, measure them and prevent fraud. If you agree, also to personalise ads. | Google AdMob and, if you agree, the ad partners listed in the consent form | Your consent (Art. 6(1)(a) and the ePrivacy rules on device storage). Where you decline, non-personalised or limited ads may still be shown, using data only as needed to deliver ads, count them and prevent fraud (legitimate interests, Art. 6(1)(f)). |
| Your consent choices | To remember what you agreed to | Stored on your device by Google's consent tool | Legal obligation (Art. 6(1)(c)) |
| Purchase details: product, time, order ID and purchase token (no payment details) | To deliver what you bought, restore it after a reinstall, and detect fake purchases | Google Play, plus a confirmation stored on your device | Performance of a contract (Art. 6(1)(b)) |
| Emails you send us | To answer you | Our email inbox | Legitimate interests in replying to you (Art. 6(1)(f)) |
3. Advertising and your consent
The app is free and funded by ads served by Google AdMob, provided for users in the EEA, UK and Switzerland by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, and elsewhere by Google LLC.
When you first open the app in a region where consent is required, Google's consent form explains the choices and lets you accept, decline or customise them. It follows the IAB Transparency & Consent Framework, and you can see which ad partners are involved. No ads are requested before this step is finished.
Changing your mind: open Settings › Privacy options in the app at any time. Withdrawing consent doesn't affect processing that already happened. You can also reset or delete your advertising ID in your phone's settings (Settings › Privacy › Ads; the exact path depends on your phone).
Watching rewarded videos is always optional.

4. Purchases and subscriptions
In-app purchases and the optional Tide Club subscription are processed by Google Play under Google's terms and privacy policy. Google handles your payment method and billing address; we only receive confirmation that a purchase happened, which the app checks on your device before delivering it. You can manage or cancel subscriptions in the Google Play Store under Payments & subscriptions.
5. Notifications
If you allow notifications, the app can remind you when your hearts are full, when your daily reward is ready, or after a few days away. These reminders are created on your phone and are not sent from any server. They respect quiet hours at night. You can turn them off in the app (Settings › Notifications) or in Android's settings.
6. Analytics and diagnostics
The app doesn't currently send analytics or crash reports to us or to any analytics provider. Gameplay events are only written to your device's local system log, which apps can't read from each other. If we ever add an analytics or crash-reporting service, we'll update this policy first and ask for consent where required.
7. Backups
If Android backup is turned on for your Google account, Android may include the app's game data in your device's encrypted backup to Google Drive, so your progress can be restored on a new phone. Google operates this backup for you and you control it in your phone's settings; we have no access to it.
8. Permissions the app uses
| Permission | Why |
|---|---|
| Internet and network state | To load ads and talk to Google Play |
| Advertising ID | Used by AdMob as described in section 3, according to your consent choices |
| Notifications (Android 13 and later) | To show the optional reminders in section 5. Asked only after you've played a few levels, and only with your permission. |
The app doesn't use your camera, microphone, contacts, photos, files or location.
9. Who receives data
- Google (AdMob and Google Play), as described above.
- If you consent to personalised ads, the advertising partners listed in Google's consent form.
- Authorities, only if we are legally required to disclose data.
We don't sell personal data and don't share it with anyone else.
10. Transfers outside the EU/EEA
Google may process data in the United States and other countries. Google LLC is certified under the EU–US Data Privacy Framework (and its UK and Swiss extensions), and Google also uses the European Commission's Standard Contractual Clauses for transfers. See policies.google.com/privacy/frameworks.
11. How long data is kept
- Game data on your device: until you reset your progress (Settings › Reset all progress), clear the app's storage, or uninstall the app.
- Data held by Google for ads and purchases: according to Google's retention policies (policies.google.com/technologies/retention). Purchase records may be kept as long as tax and accounting law requires.
- Emails to us: deleted once your request has been handled, at the latest 12 months later, unless the law requires us to keep them longer.
12. Your rights
Under the GDPR (and the UK GDPR) you have the right to:
- access the personal data we hold about you (Art. 15);
- have it corrected (Art. 16) or deleted (Art. 17);
- restrict processing (Art. 18) and receive your data in a portable format (Art. 20);
- object to processing based on legitimate interests (Art. 21);
- withdraw your consent at any time, with effect for the future (Art. 7(3)), via Settings › Privacy options;
- lodge a complaint with a data protection supervisory authority, in particular in the EU country where you live or work.
Because we don't run servers or accounts, we normally hold no data that could identify you. Most data lives on your device or with Google. Email us and we'll help with any request. For data held by Google, you can also use myaccount.google.com/data-and-privacy.
There is no automated decision-making with legal or similarly significant effects. Ad personalisation by Google is based only on your consent.
California and other US states
We don't sell personal information for money. Personalised advertising may count as "sharing" or "targeted advertising" under some US state laws. You can opt out in Settings › Privacy options (where shown) or by deleting your advertising ID in Android settings. We won't treat you differently for using your rights.
13. Children
The app is not directed at children under 13, and we don't knowingly collect personal data from them. In the EU/EEA, if you are under the age of digital consent in your country (between 13 and 16, depending on the country), please ask a parent or guardian before agreeing to personalised ads. If you believe a child has given us personal data, contact us and we'll delete it.
14. Security
The app stores its data in its private storage area on your device, which other apps can't access. Purchases are checked against Google Play's signature before anything is delivered. Communication with Google's services is encrypted.
15. Changes to this policy
If the app's data practices change (for example, new services are added), we'll update this page and the effective date above before the change takes effect. Where the law requires it, we'll ask for your consent again.
16. This website
This website has no cookies, no analytics and no advertising. When you visit it, the hosting provider GitHub Pages automatically processes technical data such as your IP address, the page requested, the time and your browser type. This is needed to deliver the page and keep it secure (legitimate interests, Art. 6(1)(f) GDPR). The provider keeps these logs only for a short time, under its own privacy policy.
