Privacy

We collect as little as we can.

Payments

Stripe processes your payment. We never see or store your card number. Stripe shares your email address with us so we can match your purchase to your exam.

Exam data

We store your exam's questions, your answers, and your score so your results stay available at your link. We keep a one-way hash of your email address, not the address itself, so later exams can favor questions you haven't seen. We may publish combined, anonymous statistics such as "the most-missed topics this year."

Analytics

We use Cloudflare Web Analytics, which does not use cookies or track you across sites. We don't run any advertising scripts on this site.

Ads

If you arrive by clicking one of our Google ads, Google adds a click ID to the link. We keep that ID in your browser for up to 90 days and, if you buy an exam, pass it to Stripe with your order. We then report to Google that the click led to a purchase, with the time and amount only. We don't share your name, email address or exam results with Google.
