Privacy Policy

Last updated: August 2026

What we collect

Account details (name, email), your learner profile (goals, experience, preferences), the courses you create, your lesson progress, quiz answers, mastery scores, and tutor conversations.

How we use it

To generate and personalise your courses, grade your work, track your progress, and operate the service. Course generation and tutoring are powered by Anthropic's Claude API — your prompts and lesson context are sent to Anthropic to generate responses, subject to their data-use commitments. We do not sell your personal data.

Payments

Payments are processed by Stripe. We never see or store your card details.

Safety records

Every course request is safety-classified (see the Course-Creation Policy). We keep a minimal security and audit record of each decision: the decision, policy category, a short truncated excerpt of the request, and the timestamp. These records exist to enforce the policy, review appeals, and detect repeat misuse, and are retained only as permitted by this policy and applicable law.

Retention and deletion

Your learning data is retained while your account is active. You can delete your account at any time from the Account page — this permanently deletes your profile, courses, progress, mastery data, and tutor conversations. Minimal safety and payment records may be retained where we are required or permitted to do so.

Cookies

We use a single session cookie to keep you signed in. No advertising trackers.
