Privacy policy
HarperSEO Ltd (company number 08841895) is the controller of personal data collected through this website.
What we collect
- Payments. Stripe processes payments. Stripe collects your card details and email address. We receive confirmation of payment, your Stripe session reference and your email address, not your card number. We use your email only to send your access link, now and if you ask for it again. We do not add it to a mailing list. The email is sent through Resend.
- Your results. Your results, your answers and your access token are stored in your own browser (local storage) so the site can show your progress and keep you unlocked. We do not keep your answers on our servers, and we do not ask you to create an account.
- Analytics. Only if you accept analytics cookies, we use Google Analytics to measure page views and test activity. If you decline, no analytics cookies are set.
- Technical logs. Our hosting provider, Cloudflare, processes IP addresses and request data to deliver and secure the site.
- Emails to us. If you contact us we keep the correspondence so we can help you.
Young people
Many people who use this site are under 18. The free sample needs no sign-up, no account and no personal details. Payment should be made by a parent, guardian or other adult. We do not knowingly collect personal data from under-18s other than an email address supplied at payment by whoever pays.
Why and how long
We use payment data to provide and support your purchase and to meet accounting rules (kept for the legally required period). Analytics data is used to improve the site. Contact emails and feedback messages (including an email address, if you give one) are kept while needed to resolve your query.
Your rights
You can ask to see, correct or delete your personal data, object to processing, or complain to the Information Commissioner's Office (ico.org.uk). Email us using the details on the contact page.
Who we share with
Stripe (payments), Resend (access emails), Cloudflare (hosting) and, if you accept analytics, Google (analytics). We do not sell your data.
