Privacy

Who we are: RedPen Maths is run by DefyScale (contact: hello@redpenmaths.com). We are the data controller for this site.
What we collect: your email address and, if you choose, your role (parent or student) and exam board, when you join the waitlist; and, when you buy, your email and exam board. Payment details go to Paddle, which is the merchant of record and processes them under its own privacy policy. We never see your card details.
The live demo: what you write on the demo page is sent to our AI provider (Anthropic) to be marked, then discarded. We do not store it. Spoken feedback is generated by OpenAI from the tutor's text only. We keep only anonymous daily counts, such as how many checks ran.
Security and abuse prevention: we use Cloudflare Turnstile to block bots, and we keep a one-way scrambled version of your IP address for 48 hours to limit demo use.
Why (lawful basis): your consent for waitlist emails; contract for purchases; legitimate interests for abuse prevention.
Retention: waitlist data until you unsubscribe or ask us to delete it; order records as long as tax law requires.
Your rights: access, correction, deletion, objection, and complaint to the ICO (ico.org.uk). Email us to exercise them.
Cookies: one strictly necessary session cookie for the demo. No advertising or tracking cookies. Analytics are cookie-free.
