Short version: there is no tracking pixel, no advertising network and no mailing list you did not ask for. Buying leaves an email address with Stripe so I can send you the file.
Page visits are counted, and that is all. This site uses Vercel Web Analytics, which records the page you landed on, the country it was served to, the kind of device and where the link came from. It sets no cookies, it does not follow you between sites, and it does not build a profile. Nothing it stores can be traced back to you as a person.
Nothing else runs on these pages. There is no Meta pixel, no Google Analytics, no advertising tag, no session recorder, no chat widget.
Stripe takes the payment and holds the record. Checkout happens on Stripe's own pages, not on this site, so your card details never touch this server and I never see them. Stripe collects your email address, your country, and whatever the card network needs to settle the payment. Stripe is the merchant of record for the sale, which means it also handles any VAT or sales tax due where you live.
Your email address is used to send you the file, and to send you updates to it. The delivery email goes out through Resend. Your address is passed to Resend for that message and for later update emails, which the terms commit me to sending.
I do not run a database. Stripe's own customer list is the only buyer list, which means there is one place your details live rather than several.
Vercel hosts the site and provides the analytics described above. Stripe processes the payment and stores the purchase record. Resend delivers the email carrying your download link. All three are United States companies and each publishes its own privacy notice. No one else receives anything, and nothing is ever sold or shared for advertising.
Your purchase record stays with Stripe for as long as the law requires it to be kept for tax and accounting, which is several years in most countries. Analytics data is aggregate and is not tied to you. Download links expire 30 days after purchase; the files themselves are yours permanently once they are on your computer.
Email coursemaxerr@gmail.com and ask. You can ask for a copy of what is held about you, ask for it to be corrected, or ask for it to be deleted. I read these myself and will act on them.
One honest limit: deleting your record removes you from update emails and means a lost download link can no longer be matched to a purchase, so I would not be able to send the file again by hand. And a completed sale has to stay on the books for tax purposes even after you are removed from everything else. Say which you want and I will do as much as I lawfully can.
If you are in the UK or EU and think something here is wrong, you can complain to your national data protection authority. I would rather you emailed me first.
