Privacy Policy
Effective date: August 26, 2026
Cross Echo is developed by 2531194087@qq.com ("we", "us", or "our"). This Privacy Policy explains how information may be handled when you use the Cross Echo mobile application.
Information We Collect
Cross Echo does not require an account and does not ask you to provide your name, email address, location, contacts, photos, or other directly identifying information. Game progress and settings are stored locally on your device.
Advertising and Tracking
Cross Echo may show optional rewarded advertisements when you choose to request a hint. Advertising services may process device identifiers, IP address, approximate location, and interaction information to provide, measure, and prevent fraud in advertising. Before accessing the Identifier for Advertisers (IDFA) for tracking on iOS, the app requests your permission through Apple’s App Tracking Transparency prompt. You may decline permission; the game remains playable.
Advertising partners may use their own privacy policies and technologies. You can change the app’s tracking permission at any time in your iOS Settings.
How Information Is Used
Information processed by advertising services may be used to deliver and measure advertisements, limit fraud, and improve advertising performance. We do not sell personal information directly.
Data Sharing
We share information only as necessary with service providers that operate advertising or security functionality for the app, or when required by law. We do not knowingly collect personal information from children.
Data Retention and Security
Local game data remains on your device until you delete the app or clear its data. Third-party service providers retain data according to their own policies. We take reasonable measures to protect the app, but no method of electronic storage or transmission is completely secure.
Your Choices
You can reset or change tracking permissions in iOS Settings. You can stop local data collection by deleting the app. If you have questions or requests about privacy, contact us using the email below.
Changes to This Policy
We may update this Privacy Policy from time to time. The effective date above will be updated when changes are posted.
