This policy explains what happens to your information when you play Cardculate ("the Game"), a free daily number puzzle available at this website.
Cardculate stores the following directly in your browser's local storage. This information is never transmitted to us or to any server we control:
Clearing your browser's site data or local storage will erase this information permanently. We have no way to recover it, because we never had a copy of it.
Cardculate does not require an account, a login, or any personal information (name, email, phone number) to play. We do not knowingly collect information that identifies you personally.
Cardculate may display advertising served by third-party ad networks (for example, Google AdSense/AdMob). These networks may use cookies, device identifiers, or similar technologies to serve ads, including personalized ads based on your prior visits to this or other websites. This processing is carried out by the ad network, not by us directly, and is governed by that network's own privacy policy. Where required by applicable law, you may be shown a consent prompt to choose whether personalized advertising is used.

Cardculate uses Google Analytics (GA4) to understand how the Game is used — for example, how many people visit, which pages they view, and general usage patterns. Google Analytics uses cookies and may collect information such as your IP address, device type, and browser. When you first visit, you'll be asked to accept or decline analytics cookies; if you decline, Google Analytics is not loaded and no analytics cookies are set. You can learn more about how Google handles this data at policies.google.com/technologies/partner-sites.
Cardculate is a general-audience puzzle game and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us using the details below and we will address it.
We may update this policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
