ZenGrid Privacy Policy

In short

ZenGrid works offline and has no accounts. Your puzzle progress stays on your device. The only data leaving your device is what Google AdMob uses to show ads.

What stays on your device

ZenGrid saves your progress locally, on your phone only: solved puzzles, stars, hints, XP and level, daily streak, achievements, weekly quest progress, chosen board skin and sound setting. We (the developer) never receive this data. It is deleted when you uninstall the app or clear its data.

ZenGrid has no sign-in, does not ask for your name, email, contacts, photos, location or microphone, and does not include any analytics service of its own.

Advertising (Google AdMob)

ZenGrid is free and shows ads through Google AdMob: a full-screen ad occasionally between levels, and optional video ads you choose to watch for hints or extra hearts. To serve and measure ads, Google may collect and process:

• your device's advertising ID and other device identifiers,
• IP address and approximate location derived from it,
• device and app information (model, OS version, language),
• ad interactions (views, clicks) and diagnostic data about ad delivery.

Google acts under its own privacy policy: policies.google.com/privacy, and explains its use of data in partner apps at policies.google.com/technologies/partner-sites.

Your choices

• Consent: where the law requires it (for example in the EEA, the UK and some US states), ZenGrid asks for your consent through Google's consent form before personalized ads are shown. You can change your choice anytime with the privacy button on the main screen.
• Advertising ID: you can reset or delete it in your Android settings (Settings → Privacy → Ads). Ads will then no longer be personalized.
• Optional ads: video ads for hints or hearts are only shown when you tap to watch them.

Children

ZenGrid is not directed at children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided personal information through the app, contact us and we will help.

Your rights

Depending on where you live (for example under the GDPR or California's CCPA/CPRA), you may have rights to access, delete or object to the processing of your data. Because the developer does not store personal data about you, requests about advertising data are best handled through your consent settings above and Google's tools at myaccount.google.com. You can always contact us for help.

Security and changes

Data sent by the AdMob SDK is encrypted in transit. If this policy changes, the new version will be posted on this page with a new effective date.
