Privacy

Last updated November 10, 2026.

We keep this simple and collect as little as possible.

What we collect

Your email, which you give at checkout so Stripe can send your receipt and so we can help you if you contact support. Payment details are handled entirely by Stripe — we never see or store your card number. We may record the marketing source (UTM tags) of your visit so we know which ads work.

What we do not do

No accounts, no passwords, no selling your data. Your practice progress is stored only in your own browser (local storage), not on our servers.

Cookies

After purchase we set one signed cookie that proves you paid, so the question bank unlocks on your device. That is the only cookie we require.

Processors

Stripe (payments) and Cloudflare (hosting). Each has its own privacy policy.

Your choices
