Privacy
Last updated 2 October 2026
Marble Sort is a tube-sorting 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, coins, boosters, the racers you have found, your daily streak, settings and any purchases 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 extra coins, an undo, a hint or an extra tube. 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.
Purchases
Purchases such as Remove Ads and the Starter Pack go through Google Play. We never see your payment details. RevenueCat checks the receipt and remembers what you own, using an anonymous ID created by the app, so a purchase comes back on a new phone. See RevenueCat's privacy policy.
Google Play Games
If you use Google Play Games, the app can post your level, stars and daily streak to its leaderboards and unlock achievements. Your Play Games name and scores are then visible to other players, under Google's privacy policy. You can play without it.
Children
Marble Sort 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.
