What are cookies?
Cookies are small text files stored on your device when you visit a website. They help us remember your preferences and improve your experience on EPSO Genius.
How we use cookies
We use cookies for the following purposes:
- Authentication — to keep you logged in to your account.
- Preferences — to remember your test mode and settings.
- Analytics — to understand how visitors use the site and improve it (only with your consent).
- Payments — Stripe uses cookies to securely process payments.
Types of cookies we use
Essential cookies
Required for the site to function. Cannot be disabled. Includes session cookies for authentication (Supabase).
Functional cookies
Remember your preferences (e.g., selected test type or mode). Stored locally in your browser.
Analytics cookies (consent required)
PostHog (EU-hosted) and Vercel Analytics collect anonymised usage data to help us improve the platform. These cookies are only set after you give consent via our cookie banner. PostHog tracks page views, feature usage, and test completion patterns. Vercel Analytics collects basic page performance metrics.
Third-party cookies
Stripe may set cookies during payment processing. These are governed by Stripe's own privacy policy.
Your consent
When you first visit EPSO Genius, a cookie banner asks for your consent before any non-essential cookies are set. You can change your choice at any time by clearing your browser cookies — the banner will reappear on your next visit. Essential cookies do not require consent as they are strictly necessary for the service to function.
Managing cookies
You can also control cookies through your browser settings. Note that disabling essential cookies will prevent you from logging in or using the platform. Most browsers allow you to:
- View what cookies are stored
- Delete cookies individually or all at once
- Block cookies from specific or all websites
