This Privacy Policy applies to the mobile game Castle Jump
(com.zackchi.markovianstairs) (the “App”), published on Google Play under the developer name
Xilencer. The App is provided by YU-SHU CHI (the “Developer”).
The App is designed to be played without creating an account. The Developer does not collect, store, or share personal information from your use of the App.
We do not collect any user data inside the App.
If you contact the Developer for support, the Developer will receive your email address and the contents of your message. This information is used only to respond to you and provide support.
The App is distributed through Google Play. Google may collect information independently as described in Google’s Privacy Policy. The Developer does not receive personal data from Google Play beyond what is shown in Play Console for app management (for example, aggregate install counts).
The Developer does not share user data with third parties because the Developer does not collect user data from the App.
The App does not collect user data, so there is no in-app user data to retain. If you email support, the Developer retains your message only as long as needed to respond and provide support, and may keep it for a reasonable period for troubleshooting or record-keeping.
The App is suitable for a general audience. The Developer does not knowingly collect personal information from children under 13. If you believe a child has contacted the Developer and provided personal information via email, please contact the Developer so it can be deleted.
The Developer takes reasonable measures to protect information received via support emails.
This Privacy Policy may be updated from time to time. Updates will be posted on this page with a new effective date.
