Marble Logic (the "Game") respects and protects your privacy. The developer is Yuchen Chang.
The Game does not collect, store, or transmit any personal or device data. There are no user accounts, no analytics, no advertising, and no third-party tracking SDKs. The Game makes no network connections at all.
The only data the Game creates is your game progress and purchase status, stored locally on your device (the files progress.json and purchase.cfg). These files never leave your device, are never uploaded, and the developer cannot access them. Deleting the app deletes this data.
The Game offers one non-consumable in-app purchase, "Unlock All Levels". The transaction is handled entirely by the Apple App Store. Neither the Game nor the developer handles, receives, or stores any payment information.
The Game collects no data of any kind, including data from children.
Any changes to this policy will be posted on this page with a new effective date.
