1. Data we store on our server

When you sign in with Google Play Games, the game sends the following to a server we operate ourselves:

DataPurpose
Your Google Play Games player ID and display nameTo identify your profile and show your name on leaderboards
Game progress: level, coins, owned and equipped items, character appearance, equipped petTo save your progress across devices
Scores with date and timeAll-time and monthly leaderboards
Monthly challenge results (rank, badge, pet won)To award monthly prizes

Your display name, scores and character appearance are public: they are shown to other players on the leaderboards and in PvP ghost battles. We do not sell this data or share it with anyone else.

2. Data stored only on your device

Settings such as music on/off, remaining lives and the number of ads watched today are stored locally on your device and never leave it.

3. Advertising (Google AdMob)

The game contains one optional rewarded video ad, which you can choose to watch for extra lives. Ads are provided by Google AdMob and, through AdMob mediation, by its ad partners (such as Meta Audience Network and Liftoff). These services may collect your device's advertising ID, IP address, device information and how you interact with ads, to show and measure ads.

If you are in the EEA, the UK or Switzerland, the game asks for your consent before personalised ads are shown. You can change your choice at any time with the Privacy button in the main menu. If you do not consent, you may still see non-personalised ads.

See How Google uses information from apps that use its services and the Google Privacy Policy.

4. Google Play Games Services

Sign-in and your player identity are provided by Google Play Games Services, under the Google Privacy Policy.

5. Legal basis (GDPR)

6. How long we keep data

Profiles, scores and awards are kept for as long as the game is offered, so leaderboards and past monthly results stay available. We delete your data sooner if you ask us to.

7. Your rights

You can ask us for a copy of your data, to correct it, or to delete it, by emailing kajusvoncarstein@gmail.com from any address and telling us your in-game name. You also have the right to complain to a data protection authority.

8. Children

Monster Stack is not directed at children under 13, and we do not knowingly collect data from them.

9. Changes

If we change this policy, we will update this page and the date above.
