Privacy Policy
Nice and short, because a policy nobody reads protects nobody.
Last updated 24 August 2026
What we collect
Your name, email address and date of birth (we do not accept accounts under 13), and everything a lesson produces: the conversation with your tutor, the whiteboard notes, any work you upload for marking, your flashcards and study notes, and a record of your credits.
Who else touches it
Anthropic runs the tutor and OpenAI handles the speech, so your lesson conversation and anything you upload passes through them. Supabase stores your account and Vercel runs the site. All four act on our instructions and for nothing else.
How long we keep it
Your account and everything in it stays until you delete it — it is your lesson history, and putting a timer on that would delete the thing you signed up for. The AI provider's working copy of each lesson is deleted 7 days after the lesson ends.
Deleting your account
From the profile screen, whenever you like, without asking us. It is immediate and permanent, and it takes the AI provider's copy with it. We keep one scrambled trace of your email address so the free starter credits cannot be claimed twice — it cannot be turned back into an address. Sign up again any time; you would just start without the free credits.
What we do not do
We do not sell your data, share it with advertisers, or use your lessons or your uploaded work to train AI models.
Anything else
Questions about any of this, or about your own data, go to hello@curriculumcodex.com. If you are under 18, ask a parent or guardian to get in touch on your behalf.
