Cookies we use

This page explains the cookies (and similar storage) that may be set when you use Kvantfin.

Essential

These are required to make the app work (for example: keeping you signed in, protecting the app, and remembering your settings).

  • kvantfin_cookie_consent (1 year) stores your analytics cookie preference.
  • Authentication cookies may be set when you sign in (via NextAuth.js) to keep your session active.
  • kvantfin_dev_user (development only) may be set when using the dev auth bypass.

Analytics (optional)

If you accept analytics cookies, we use PostHog to understand how the product is used and to improve it. PostHog typically stores a pseudonymous identifier and session information.

  • ph_<project>_posthog (cookie/localStorage) stores PostHog analytics state like a distinct ID and session-related properties.
  • __ph_opt_in_out_<project> (localStorage or cookie) may store your PostHog opt-in/out state.

Cookie names can vary based on PostHog configuration and project key.
