Privacy Policy

Last updated: October 29, 2026

Your manuscript and cover images never leave your browser. We store only what a payment needs, and we don’t sell data.

Files you check, fix or turn into a cover

PDFs and images are read, checked, fixed and exported entirely in your browser. They are not uploaded to our servers or to anyone else. When you buy, we store a SHA-256 fingerprint of the PDF (a 64-character code that can’t be turned back into the file) so your purchase unlocks that book, plus its file name and page count.

Payments

Payments are processed by Stripe. We receive the order amount, status, payment reference and the email address you give Stripe, and keep them for accounting and refunds. We never see your card number. See Stripe’s privacy policy.

Your browser

After a purchase, an unlock code for that book is saved in your browser’s local storage for 30 days so the downloads unlock again for the same PDF. Clearing site data removes it.

Analytics

We use Google Analytics 4 to count visits and anonymous events such as “check completed” or “purchase” (with the amount). These events contain no file contents. Campaign parameters (utm_*) and the referring site are stored with an order to see which channels work.

Hosting and logs

The site runs on Cloudflare. Cloudflare processes request data (such as IP addresses) to deliver and protect the site.
