Mirror Duo (かがみあわせ, "the app") is developed by materialchain ("we"). This policy explains what information the app handles and how.
If you are signed in to Game Center, your total stars and achievements are sent to Apple's Game Center and shown on leaderboards. Apple's privacy policy applies to them.
The app shows Google AdMob ads between stages. To deliver and measure ads, AdMob may collect information such as advertising identifiers and information about your device and usage. In regions that require consent, such as the EEA, the UK and Switzerland, you can choose through Google's consent form and change your choice at any time from the app's Settings. See Google's privacy policy for details.
The app does not knowingly collect personal information from children.
We may update this policy. The latest version is always available on this page.
