Privacy policy
Effective July 27, 2026. Review this document against the final operator and production domain before launch.
Data stored locally
Deck names, card information, settings, and results are stored in your browser's IndexedDB. The service operator cannot access them and they are not sent to a server.
You can remove saved projects through your browser's site-data controls.
Advertising and consent
When advertising is enabled, partners such as Google AdSense may use cookies or similar technologies. In applicable regions, choices and consent withdrawal are provided through a Google-certified consent management platform.
Analytics
The default analytics adapter sends no data. If anonymous analytics is added later, card names, deck names, tags, and complete share URLs will not be collected.
External services and contact
Technical logs from static hosting and advertising services may be processed under each provider's policy. The support link opens Buy Me a Coffee under its privacy policy and never includes deck data. Replace the placeholder contact address before launch.
