Privacy Policy

On-device game data. Your puzzle progress, elapsed time, hints used, and preferences (such as theme and conflict highlighting) are stored in your browser’s local storage. This stays on your device; we do not upload it.

Usage analytics. We use Google Analytics to understand how the Site is used (pages visited, approximate region, device and browser type, and in-game events). This is aggregate and not used to identify you personally.

Advertising data. We display ads through Google (AdSense / Ad Manager). Google and its partners may use cookies and similar identifiers to serve and measure ads, including, where permitted, personalized ads based on your prior activity.

We do not ask for, or knowingly collect, your name, email, or payment information.

The Site and our providers (Google Analytics and Google ads) use cookies, local storage, and similar technologies to remember preferences, measure usage, and serve ads. You can clear or block cookies in your browser settings; doing so may affect ad relevance but not your ability to play.

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. You can control personalized advertising:

• Google Ads settings: adssettings.google.com
• Opt out of many vendors: optout.aboutads.info and youronlinechoices.eu (EEA/UK)
• How Google uses data: policies.google.com/technologies/partner-sites

Where required (e.g. the EEA and UK), we present a consent prompt before non-essential cookies and personalized ads are used, and honor your choice.

Depending on where you live, you may have the right to access, correct, or delete personal data, and to opt out of the “sale” or sharing of personal information for targeted advertising. Because we do not hold account data, most requests are handled through the ad and cookie controls above. To make a request or ask a question, contact us at the address below.

The Site is not directed to children under 13, and we do not knowingly collect personal information from them. Ads are served in a manner intended to be appropriate for a general audience.

On-device data persists in your browser until you clear it. Analytics and ad data are retained by the respective providers per their policies. We use reputable providers (Google, AWS) but no method of transmission or storage is completely secure.

We may update this policy as the Site evolves. Material changes will be reflected by the “Last updated” date above.
