What we collect

Product analytics via PostHog (page views, tool and practice events, coarse geography, device type). No account is required to use the free features; your diagnostic answers and study-plan inputs are stored only in your browser's local storage until you choose to create an account.

Payments

If you buy Pro, payment is handled by Polar; we receive the order status and an email address to attach the entitlement. We never see card numbers.

Cookies

Analytics uses first-party storage. No advertising cookies.

Your rights
