Enrollment is closed while the publisher details and release checks are finalized.
Who handles your data
The course publisher is responsible for account and course delivery data. Paddle separately handles payment data under its own privacy notice. Publisher contact information is shown below; sales remain closed until it is complete.
Data and purposes
We use account email and authentication information to secure your account; order, transaction and entitlement records to deliver and support purchases; compact lesson checkpoints to restore bookmarks across devices; and operational error and usage records to maintain the service and control costs.
Providers
Vercel hosts the website; Supabase handles authentication and database records; Paddle handles checkout, tax and payment receipts; Resend sends transactional emails; Sentry reports operational errors; and Vercel Analytics measures aggregate website use. AI requests send the selected chat context to Nebius only when you use the AI feature. Provider processing terms, transfer arrangements and retention must be reviewed before enrollment opens.
Browser storage
Authentication uses session cookies. Language and theme preferences and local exercise drafts use browser storage. Exercise drafts, charts and evidence remain on your device; only compact lesson checkpoints sync to your account. Importing signed-out progress into an account requires your action. Clearing browser storage can remove local drafts.
Retention and your rights
We keep account and course records as needed to deliver the purchase, resolve support requests and meet applicable legal obligations. Specific statutory retention periods are confirmed by the publisher before sales open. You may request access, correction, export or deletion via course support, subject to required record retention. You may also contact the relevant supervisory authority.
Diagnostics and marketing
Session replay is disabled. Error reporting uses sampled traces and avoids default personal-information collection. The course purchase and terms checkbox do not subscribe you to marketing emails.
