What this site collects. The short answer is: nothing.
This site does not collect personal data. There is no account, no login, no contact form, no analytics script, no advertising pixel and no third-party tracker on the page.
The register writes nothing to your device. It does not use cookies, localStorage, sessionStorage or IndexedDB. Which asset you have selected and the drifting signal values in the integrity panel are held in page memory only and are gone the moment you close or reload the tab.
This is a deliberate engineering position as well as a privacy one: browser-local storage is device-locked and silently cleared by cache clears, private windows, browser updates and new devices. Anything that matters belongs on a backend, and anything that does not matter does not need to be written to your machine at all.
Statuses are computed locally by the engine script the page loads. The register does not send your reads, selections or interactions anywhere for processing.
Typefaces are loaded from Google Fonts, which means your browser makes a request to fonts.googleapis.com and fonts.gstatic.com. Those requests are subject to Google's own privacy terms and are the only third-party requests the page makes. Self-hosting the fonts to remove them is a tracked change.
The static host serving these files may retain standard request logs (IP address, user agent, requested path, timestamp) for operational and security purposes. BEDROCK does not use those logs to build profiles and does not join them to any other data.
Questions about this notice can be raised through the same channel as evidence disputes, which is published alongside the dispute procedure when that phase ships. It is listed as not started in the state-of-build section.
