Privacy Policy
This page explains what information the apps made by Kuromu (the "Apps") handle, and how.
Information I collect
I do not collect personal information such as your name, email address, or home address. The Apps have no account sign-up.
Information stored on your device
Cleared stages, coins, settings (such as sound volume), and records of your purchases are stored only on your device. They are never sent to my servers. If you delete an App, this data is deleted too.
Ads (Google AdMob)
The Apps show ads through Google AdMob. To show ads and measure how they perform, Google may collect information such as:
- Device type, OS version, and approximate location (from your IP address)
- Whether an ad was shown or tapped
- Your advertising identifier (IDFA), only if you allow tracking when asked
If you don't allow tracking, you will see ads that are not personalized. You can change this at any time in Settings → Privacy & Security → Tracking. For how Google handles this information, see How Google uses information from sites or apps that use its services and the Google Privacy Policy.
In-app purchases
In-app purchases are paid through Apple. I never receive your card number or other payment details.
To verify purchases and restore them, the Apps use RevenueCat, a purchase management service. RevenueCat receives an anonymous identifier created in the App (it does not include your name) and your purchase history. See the RevenueCat Privacy Policy.
Children
I do not knowingly collect personal information from children under 13.
Changes to this policy
I may update this page when the Apps change. If there are major changes, I will announce them on this page.
