Privacy Policy
In short
- The game asks for no account, no name and no email address.
- Your game is saved only on your phone.
- Ads are provided by Google AdMob, which processes some data with your consent.
- Gameplay statistics (with your consent in Europe) and crash reports help improve the game.
- Payments go through Google Play: the game never sees your payment details.
Who is responsible
Builder's Kingdom is a game developed by Alexis, an independent developer. For any question about your data: avdev78@gmail.com
Data stored by the game
Your progress (waves, buildings, upgrades, crowns, gems, sound and tutorial settings) is stored in your phone's memory. It is not sent to the developer. Uninstalling the game deletes it.
Ads (Google AdMob)
The game shows ads, some of which are optional and give a reward. They are provided by Google AdMob, which may process:
- your device's advertising ID;
- your IP address, which gives an approximate location;
- technical information about the device (model, Android version, language);
- your interactions with ads (views, clicks).
This data is used to show ads, measure their performance and prevent fraud. In the European Economic Area and the United Kingdom, your choice is requested at first launch through Google's consent form; you can change it at any time from the game menu ("Privacy"). You can also reset or delete your advertising ID in Android settings (Google › Ads).

Statistics and crash reports (Firebase)
To improve the game, it uses Google Firebase Analytics and Firebase Crashlytics:
- Gameplay statistics: game started or abandoned, wave completed, castle destroyed, revive, gem conversion, with technical information (device model, Android and game version, approximate country). They are linked to a random installation identifier, never to your name or email address. In the European Economic Area and the United Kingdom, they are only collected with your consent, given in the same form as for ads.
- Crash reports: if the game crashes, technical information (device, version, error trace) is sent so the problem can be fixed. It is kept for 90 days.
The developer only sees overall statistics and these technical reports. Learn more: Firebase and privacy.
In-app purchases (Google Play)
Gems and ad removal are bought through Google Play's payment system. The game only receives a purchase confirmation to credit you; it never has access to your payment method. These payments are governed by Google's privacy policy.
Google Play Games save (optional)
If you sign in to Google Play Games from the menu, your gem balance and, if you bought it with gems, ad removal are saved in your Google Play Games account so you can get them back after reinstalling or on another phone. No other data is sent.

Children

Your rights
You have the right to access, correct, delete and object to the processing of your data. Since the developer has no data that identifies you, these rights are mainly exercised with Google (ads, Google Play, Firebase). For any question, write to avdev78@gmail.com. To delete your data, follow these steps. You can also file a complaint with your data protection authority (in France, the CNIL).
Changes
This policy may change as the game evolves, for example if new services are added. The date at the top of the page shows the latest version.
