Privacy and site analytics.
Fit answers stay inside the browser. On the production FPSU domains, this site may send limited, aggregate website analytics to PostHog Cloud EU: page paths without query strings or fragments, page-leave timing, referrer origin, basic browser/device display metadata and explicit CTA identifiers. We measure scroll thresholds and numeric Web Vitals to understand page performance. We also count waitlist submission attempts, processed requests, fixed error categories and explicit questionnaire skips, without sending email addresses, answers or signup identifiers to PostHog. A processed request does not establish that a new unique contact was created. Input content, account identity, person profiles, session replay, autocapture, feature flags, surveys and console error collection are not used. Limited error tracking counts unhandled browser errors by fixed category, without messages, stack traces, error causes or input values. Requests pass through our website to PostHog; signup cookies and authorization headers are not forwarded by this analytics proxy.
Analytics runs in PostHog's cookieless mode with in-memory browser state and no FPSU analytics cookies or local/session-storage identifiers. PostHog may receive an IP address as part of the network request; the project is configured to discard IP data, and PostHog describes cookieless measurement as using a privacy-preserving server-side hash. Network metadata can still be processed as part of delivering and measuring the site.
Analytics is disabled on local previews and when the browser signals Do Not Track or Global Privacy Control. No transactional service can open until its exact privacy policy is connected.
Public source, medium and campaign labels may be measured without URL query strings. Separately, a new waitlist signup can retain its first-entry public labels or a known referring site category in our private database, unless either of those privacy signals is present. We do not join PostHog visitors to contacts or send contact identities to PostHog. See Waitlist privacy for retention and deletion.
