Orders and your library

Stripe hosts payment checkout. We do not store full card numbers. We use your purchase email, payment reference, paid and refunded amounts, and order status to fulfill and support the purchase. Clerk verifies your account email and manages sign-in. Convex stores orders, course ownership, lesson progress, and delivery records. Private Vercel Blob storage holds the course files. Resend delivers order and course-release emails; replies go to berny@webshinobi.com.

We match a paid order only to a verified email belonging to the signed-in user. An order confirmation URL does not grant course access. Service providers process the data needed to operate their parts of the service.

Necessary service data

Vercel hosts this website and may process technical request information to deliver and protect it. Clerk uses necessary authentication cookies. We use a checkout reference cookie to check your payment status after returning from Stripe. If you arrive from an ad link, your browser tab remembers its campaign label until you close it, so the label is not lost if you read the terms before ordering; it is saved with an order only if you allow advertising measurement. Fonts are served from this website. We retain order records needed for fulfillment, refunds, accounting, and resolving disputes; request help or deletion through the support address below.

Optional advertising measurement

When Meta measurement is enabled, we ask before loading advertising cookies or reporting events. If you allow it, we may report checkout starts and verified purchases to Meta using event identifiers, amount, currency, campaign labels, browser advertising identifiers, and a hashed purchase email. Hashing helps matching; it does not make the information anonymous. Test payments are excluded.

You can decline and still buy and use the course. Use “Privacy choices” when shown to withdraw consent for future browser measurement. Withdrawal does not recall events already transmitted. Contact us if you also want pending measurement records removed.

Your choices and support

Contact berny@webshinobi.com to ask about your information, correct a purchase email, request deletion, or discuss privacy. We do not publish customer details in business reports.

If you email us asking to hear when preorders open, we use your address for that one message only.
