Match & Defend
Privacy policy
This policy describes the Match & Defend app (also named 小小守城) and this support website, provided by AiStudioWorks. Effective date: September 18, 2026.
Local game data
The app saves scores, tutorial completion and preferences locally. It creates a random app-specific UUID and test-device marker in Apple Keychain to select test ads on development devices. This UUID is not sent to our server or passed to the advertising SDK by our app code. Keychain records may remain after uninstalling.
Advertising and consent
The app uses Google AdMob for app-open and optional rewarded ads, and Google UMP for privacy choices. Google's SDK may process IP address and approximate location, device or app-scoped identifiers, ad impressions and interactions, diagnostics and performance data for advertising, measurement and fraud prevention. Processing depends on SDK configuration, permissions and applicable consent. Our current app does not request ATT authorization to access IDFA.
This website
Firebase Hosting serves these pages. Google may process network information such as IP addresses and request metadata to deliver and secure the website. We have not added analytics, advertising scripts or tracking cookies to these pages.
Support requests
If you email us, we receive your email address and any information you choose to include. We use it to respond and troubleshoot, retaining it only as needed for support and applicable obligations. Please do not send passwords or sensitive data.
Your choices and retention
You can manage required ad privacy choices in the app menu when available, and review iOS privacy settings. Removing the app removes its local app data, subject to device backups; Keychain data may remain. Contact us about access, correction or deletion of support correspondence and other applicable privacy rights. Data handled by Google follows Google's policies and retention practices, and may be processed outside your country.
Children and changes
The app is not specifically directed at children. Contact us if you believe a child has provided personal information through support. We may update this policy and will revise the effective date on this page.
