Pop Chain does not collect personal information, browsing history, website content, location data, or advertising identifiers. The game runs locally within the extension popup and does not use advertising, analytics, or tracking services. No data is sent to a server, sold, or shared with third parties.


The extension stores language, sound, and reduced-motion preferences, as well as the best score, longest chain, and whether the tutorial has been viewed. This information is used only to preserve the user's preferences and game progress.


The storage permission is used only to save game settings and records after the extension popup is closed. It does not provide access to browsing history, website content, or personal files, and it is not used to transmit information over the internet.


The donation link opens an external website only when selected by the user. The privacy policy of that website applies after the user leaves the extension.
