Privacy Policy
Last updated: September 7, 2026
Overview
Kendoku Master is a logic-puzzle game by Marvio Studio. The game is designed to work offline and does not require an account. The free version may display banner advertisements provided through Google Mobile Ads / AdMob.
Information stored on your device
Game progress, puzzle statistics, achievements, Daily Puzzle completion, hints, and appearance preferences are stored locally on your device. This information is not sent to Marvio Studio.
Advertising and Google AdMob
To provide and measure advertisements, the Google Mobile Ads / AdMob SDK and its advertising partners may process technical and device information. Depending on your device, region, consent choices, and the ad request, this can include IP address, device or advertising identifiers, approximate location, diagnostic information, and advertising interaction data. Google and its partners use this information to deliver ads, measure their performance, prevent fraud, and, where permitted and consented to, personalize advertising.
Your privacy choices
In the European Economic Area, the United Kingdom, and Switzerland, we present a consent message where required before requesting ads. You can accept, decline, or manage your advertising choices. Where available, you can revisit these choices at any time from the app’s Settings screen under Privacy Choices. Declining consent may limit the availability or relevance of advertisements.
No account required
Kendoku Master does not require you to create an account. We do not sell your game progress or use it to identify you.
Children’s privacy
Kendoku Master does not knowingly request personal information directly from children. If you believe that a child has provided personal information to us directly, please contact us so that we can address the request.
Third-party policies
Advertising data is handled by Google and its advertising partners under their respective privacy policies. You can review Google’s privacy policy at policies.google.com/privacy.
