Privacy & analytics
Updated 9 September 2026
Optional usage analytics
With your consent, Google Analytics helps TK Lab understand which projects, test categories, metrics, photos and videos readers find useful. We measure page views, selected filters, opened evidence previews, video progress, visible sections and active reading time.
We do not send typed search text, original filenames, local or NAS paths, login tokens, private evidence or account identities. Search analytics contains only query length and result count. Google may process pseudonymous device identifiers and technical request data. Advertising storage and personalization remain disabled.
GA4 event-level data is configured for 14 months of retention. Pseudonymous user-data retention is also 14 months and may reset with new activity; aggregated reports may be retained longer. Browser consent and analytics cookies use a separate 180-day period.
Your choice
Analytics does not load before you agree. Declining does not restrict reading or media playback. Your choice is saved on this browser for 180 days; you can change it using Analytics preferences below. Global Privacy Control or Do Not Track signals are respected. Blocking analytics means your visit may not appear in reports.
