Cookie Policy
Last updated: September 28, 2026
What are cookies?
Cookies are small files stored on your device. We also use similar technologies such as local storage. This policy explains what we use and how you control it.
Strictly necessary (always on)
These make the site work and cannot be switched off:
- sb-…-auth-token — keeps you logged in (Supabase), session length
- iq_attempt — links the test you just took to your browser, 60 days
- iq_analyzed — remembers that your results were analysed, 60 days
- NEXT_LOCALE — your language, 1 year
- cookie-consent (local storage) — your cookie choice
- __stripe_mid, __stripe_sid — Stripe fraud prevention during checkout, up to 1 year / 30 minutes
- Cloudflare Turnstile — our bot check runs in a separate Cloudflare frame and does not set cookies on our domain
- sentryReplaySession (session storage) — lets us understand an error if one happens, until you close the tab
Analytics (only if you accept)
If you click "Accept" we use:
- ph_…_posthog — PostHog product analytics, 1 year
- _ga, _ga_… — Google Analytics, 2 years
If you decline or don't choose, we measure visits without cookies: PostHog counts page views anonymously using a daily-changing, privacy-preserving identifier created on its servers, and nothing is stored on your device (apart from recording your choice).
Managing your choice
You can accept or decline analytics cookies in the banner. To change your choice later, clear this site's cookies and storage in your browser settings and the banner will appear again. Blocking strictly necessary cookies may stop login and checkout from working.
