Clever Cat Games ("we," "us," or "our") developed Hanadoku (the "App"). This Privacy Policy explains what information the App collects and how it is used. By using Hanadoku, you agree to the practices described in this policy.
We do not collect, store, or transmit any personal information ourselves. The App is fully playable offline, and we do not require you to create an account or provide any personal details to play. Our advertising partner, Google AdMob, does collect some information in order to serve ads — see the Advertising section below.
Any data generated while you play, such as puzzle progress and settings, is stored locally on your device and is not sent to us or any third party.
Hanadoku displays advertisements served by Google AdMob to support continued development of the App. To serve, measure, and (where permitted) personalize these ads, AdMob may collect information such as your device's advertising identifier, IP address, general location, device information, and how you interact with ads. Some of this information may be considered personal data under applicable law.
You can control ad personalization through your device's settings (for example, Android's "Opt out of Ads Personalization" option) or through Google's Ads Settings at https://adssettings.google.com . You can review Google's advertising practices at https://policies.google.com/technologies/ads and their privacy policy at https://policies.google.com/privacy .
Hanadoku is intended for a general audience and is not directed at children under the age of 13. We do not knowingly collect personal information from children, and ad requests made by the App are not configured to treat users as children.
We do not collect, retain, sell, or share personal information ourselves. The only data collection that occurs is by Google AdMob, as described in the Advertising section above, and is subject to Google's own retention and privacy practices.
We may update this Privacy Policy from time to time, for example if we add new features such as advertising, analytics, or cloud saves. Any changes will be posted on this page with an updated "Last updated" date.
