Privacy

Last updated 17 October 2026

Marble Post Office is a 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 route progress and stars, your coins and Rush Hour best, your settings (sound, music and vibration), which tips you have seen and whether you bought Remove Ads 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. Some are ads you choose to watch for a reward, such as two extra stamps when you run out, a Tea break booster or double coins. A small banner ad shows below the game, and now and then a short ad plays between levels (neither for players who bought Remove Ads). 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

Remove Ads is bought 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.

Delete your Marble Post Office data

Marble Post Office by Daily Marble has no accounts, so most of your data never leaves your phone. To delete it:

1. Game progress on your phone (routes, stars, coins, settings): open your phone's Settings, then Apps, then Marble Post Office, then Storage, and tap Clear data. Uninstalling the app also deletes it. To stop a copy coming back from your Google backup, turn off backup for Marble Post Office in your phone's backup settings.
2. Ad data: in your phone's Settings, go to Google, then Ads, and tap Delete advertising ID (or Reset). This cuts the link between you and what AdMob collected.
3. Purchase records (Remove Ads): email rsoc.dev@gmail.com with the subject "Delete my Marble Post Office data" and your Google Play order number (it starts with GPA., and is in the receipt email from Google). We delete your anonymous RevenueCat customer record within 30 days and reply when it's done.

What is kept: Google keeps its own record of your Google Play orders, as required for tax and accounting, under Google's privacy policy. Once your RevenueCat record is deleted, Restore purchases can no longer bring Remove Ads back on a new phone. Nothing else about you is kept by us.

Children

Marble Post Office 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.
