Privacy Policy
Cards4.net is designed to collect as little personal information as possible. The site exists to let you play card games, not to build a detailed behavioral profile of your browsing habits. We keep the experience focused on gameplay, and any data handling is limited to what is needed to provide the service, keep the site secure, and make the application function reliably.
If you sign in, the account system uses magic links rather than passwords, which reduces the amount of sensitive information stored or transmitted. Session data is used to keep you signed in and to maintain a working game experience, but the overall philosophy remains minimal collection and minimal retention. We do not want unnecessary data, and we avoid features whose purpose is tracking rather than service delivery.
Operational logs and diagnostic signals may exist to help keep the site healthy, but they are intended for maintenance and error handling, not advertising or cross-site profiling. The privacy posture is simple: play the games, keep your data footprint small, and avoid surprise uses of your information. If this policy changes, the goal will always be to preserve that same privacy-first approach.
