Provisional version — legal review pending (#622)

This page is not yet a legally reviewed privacy policy. Until it is, opt-ins collected on this site (e.g. the checkout marketing checkbox) are not treated as legally valid consent.

Privacy Policy

What this app technically stores

We would measure pseudonymised page and PWA usage. Your IP address and browser signature are not stored in the process. Your choice is optional.

When you agree to the marketing opt-in at checkout, we store: your consent state (opted in or withdrawn), the timestamp, the surface where you decided (e.g. course checkout), and the version of this notice. Withdrawing via the unsubscribe link or account settings ends the active consent; the history is kept as an audit trail and is not deleted.
