What we store
When you finish the test and enter your details we store: your first and last name, your email address, your answers to the test questions, the result calculated from them (level, score and breakdown), the interface language, and, if you buy the certificate, the payment status, the date of issue and the certificate ID.
We do not receive or store your card details. Payments are handled entirely by Stripe.
Why we store it
To calculate your result, to issue your certificate with your name, to send you the link to your certificate by email, to let anyone check a certificate by its ID, and to keep records of sales.
The public verification page only shows the name, level and date of issue of a valid certificate. It never shows your email address or your answers.
Service providers
Supabase (database), Stripe (payments), Resend (sending emails) and Vercel (hosting the website). They process data on our behalf to provide these services.
How long we keep it
We keep the data of a purchased certificate so that the link and the verification keep working. Tests that were never paid for may be deleted after some time.
Your rights
You can ask us to see, correct or delete your data at any time by writing to function(){throw Error("Attempted to call CONTACT_EMAIL() from the server but CONTACT_EMAIL is on the client. It's not possible to invoke a client function from the server, it can only be rendered as a Component or passed to props of a Client Component.")} from the email address you used. If you delete a purchased certificate, its link and verification will stop working.
