Fernwick Roasters is a demo store made by PrivacyFixed to test its WordPress plugin. No orders are taken and no account can be created.
To show how PrivacyFixed finds and holds trackers, this site loads the scripts a typical small shop has: Google Analytics, the Meta pixel and Hotjar on every page, and the TikTok pixel and Microsoft Advertising on checkout. Their account numbers are made up, but your browser still contacts those companies when they load. The cookie banner and PrivacyFixed Consent Guard decide when that happens.
The server keeps its standard access logs. Nothing else about visitors is stored by the shop.
