Cookie policy

We use only what the site needs to work: staying signed in, keeping your cart, and remembering a few preferences. We don’t use advertising, analytics or tracking cookies, so there is nothing to opt out of.

• Sign-in (Clerk). Keeps you signed in securely and protects your account. Set when you sign in; removed when you sign out or the session expires.
• Payments (Razorpay, PayPal). Their checkout windows set their own cookies to process payment and prevent fraud, only while you pay.

Some things are kept in your browser’s own storage and are never sent to us until you act on them:

• Your cart, so it survives a page reload before you sign in.
• A coupon code you entered, for the current visit only, and your detected currency, for up to an hour.
• Questions you marked for review during a test, and your layout preference in the test player.
• Code drafts in the online compilers.

You can clear cookies and site data in your browser settings at any time. If you block sign-in cookies, you won’t be able to sign in. See our privacy policy for how we handle personal data.
