A small, readable storage map.

Essential storage

bk-theme remembers dark or light mode. Language and interactive checklist preferences may also be stored locally when you use those controls.

bk-analytics-consent remembers whether you accepted anonymous analytics and experience replay. This prevents the same choice from being requested on every visit.

These items support requested site behavior and do not create an advertising profile.

Optional PostHog storage

After analytics consent, PostHog may use first-party cookies and local storage to distinguish pseudonymous sessions, measure repeat visits and connect events inside a journey.

After replay consent, the same service may associate a masked interaction reconstruction with that pseudonymous session.

Exact storage names and lifetimes can change when PostHog updates its software; the purpose remains limited to site analytics and usability diagnosis.

How to change your choice

Open Analytics preferences in the footer or custom context menu. Rejecting optional analytics stops future capture and resets the active PostHog identity on this site.

You can also clear site data using your browser settings. Doing so removes saved theme, checklist and consent preferences as well.
