Your privacy matters to us. This Privacy Policy sets out the types of information collected, used and safeguarded by Grid Zen ("the App") when used on mobile iOS or Android devices.
1. Information We Collect Automatically
Grid Zen is a free-to-use spatial logic puzzle supported by third-party advertising and optional in-app purchases. To provide these services, we use standard industry software development kits (SDKs) which may collect certain device-level information:
Technical data: your device model, operating system version, and system language, used to serve contextual (non-personalised) advertising. The App does not request permission to track you across other companies' apps or websites, and does not use Apple's advertising identifier (IDFA).
App data: Your level progress and hint balance are stored solely and persistently on your own device using local storage - it is never uploaded to us or to any server.
2. Third-Party Services We Use
The App integrates the following third-party services, each with its own independent privacy policy:
Google AdMob We use the Google Mobile Ads SDK to display banner and interstitial adverts. The App does not request tracking permission, so adverts are contextual rather than personalised to you individually. You can change or revoke your ad consent choice any time from the in-app Shop ("Manage Ad Consent"). You can read Google's policy here: Google Privacy Policy.
App Store Billing In-app purchases ("Remove Ads", hint packs, and "Infinite Hints") are handled securely through Apple's App Store and Google Play Billing. We never collect, process or store your card details or payment credentials.
3. How We Use Collected Data
Any device data gathered automatically is used solely to:
Serve relevant banner and interstitial advertising.
Detect your regional locale, to display prices in the correct local currency (e.g. £, $, €, ¥).
Understand aggregate usage so we can improve the App's balance, features and design.
4. Your Rights & Choices (Opt-Out)
You can restrict advertising tracking, or opt out of personalised ads entirely, from your device settings:
On iOS: go to Settings > Privacy & Security > Tracking and disable "Allow Apps to Request to Track".
On Android: go to Settings > Privacy > Ads and select "Opt out of Ads Personalisation", or reset your Advertising ID.
5. Children's Privacy
Grid Zen does not knowingly collect any personally identifiable information from children. If you believe an advertising identifier has been processed incorrectly, please contact us straight away using the details below.
