Cookie Policy

11+ Mastermind uses only the cookies and similar storage that are strictly necessary to deliver the service. We do not use advertising, analytics, or tracking cookies.

Cookies we set

Authentication (Clerk)

Our sign-in provider, Clerk, sets a small number of essential cookies on your device to remember that you are signed in, prevent cross-site-request-forgery attacks, and keep your session secure. Without these, you would have to type your password on every page.

Payments (Stripe)

When you visit the Pricing or Checkout pages, Stripe may set essential cookies to detect fraud and protect your payment. These cookies are only set on Stripe-hosted pages.

Local storage

We store a single flag in your browser's localStorage to remember that you have dismissed this cookie notice, so we don't keep showing it.

What we do not do

• No advertising cookies.
• No third-party analytics (no Google Analytics, no Meta Pixel, no Hotjar).
• No behavioural profiling.
• No targeted-advertising data sales.

Managing cookies

Because all the cookies we set are strictly necessary, switching them off in your browser will prevent the app from working properly. You can clear cookies at any time from your browser settings.

Changes

If we ever add non-essential cookies (for example, opt-in analytics), we will ask for your consent first using a clear banner.
