Cookie Policy

QualCanvas uses a small number of cookies plus browser local-storage. This page lists each one.

Strictly necessary

These can't be disabled without breaking core functionality.

Optional analytics & conversion measurement

Google Analytics, Google Ads conversion measurement and Meta conversion measurement remain disabled until you accept the banner. Cookieless Plausible analytics loads on public marketing pages and does not use an advertising identifier.

NamePurposeLifetime
_ga / _ga_*Google Analytics 4 — aggregate page views, retention.2 years
_gcl_*Google Ads — consented conversion attribution.Up to 90 days
_fbp / _fbcMeta — consented conversion attribution.Up to 90 days

Operational observability

Sentry may use a short-lived sentry-trace value to connect frontend and backend errors. We use this for service reliability, not advertising, and QualCanvas does not enable Sentry Session Replay because research content can be sensitive.

Boundaries

  • No optional analytics or advertising measurement is loaded before you accept.
  • No third-party social-button cookies on logged-out pages.
  • No fingerprinting beyond what Cloudflare / Sentry use for security & error attribution.

Managing cookies

  • In-app: open the consent banner via the footer "Cookie settings" link to turn optional measurement on or off. Withdrawing consent stops the measurement container and clears known first-party analytics cookies.
  • In your browser: standard browser settings let you delete or block any of these. Deleting the jwt cookie will log you out.
  • Opt-out across sites: consider a tool like uBlock Origin or your browser's built-in tracking-protection toggle.
