Privacy

Last updated 9 October 2026

Marbledoku is a logic puzzle game. You don't make an account, and we never ask for your name, email address or location. This page explains what the game keeps, what our partners see when you watch an ad or buy something, and how to reach us.

What the game keeps on your device

Your levels and stars, best times, hints, the racers you have met, your daily streak and your settings are saved on your phone, in the game's own storage. Android's backup can also copy them to your Google account, so a new phone gets them back; you can turn that off in your phone's backup settings. Uninstalling the app or clearing its data deletes them from the phone.

Ads

The app is free and shows ads from Google AdMob. Most are ads you choose to watch for a reward, such as an extra hint or another use of your racer's power. Now and then an ad also plays between levels. To choose and count ads, AdMob collects information about your device, including its advertising ID, its IP address and how you interact with ads. See how Google uses information from apps that use its services.

• Where the law requires it (for example in the EU and the UK), the app asks for your consent before it shows personalised ads.
• You can reset your advertising ID, or opt out of personalised ads, in your phone's settings under Google, then Ads.

Children

Marbledoku is made for players aged 13 and over. It is not directed at children under 13, and we do not knowingly collect information from them.
