The short version: your images never reach us, because there is nowhere for them to go.
Photos you open in the checker are decoded, measured and repaired inside your browser tab. They are not uploaded, not copied to a server, and not stored anywhere. The page has no upload endpoint. If you open the browser's network panel while using it, you will see no request carrying your file.
One thing: your licence key, in the browser's localStorage, so you do not have to paste it every visit. Clearing site data removes it. Nothing else is written, and no analytics, advertising or fingerprinting script is loaded.
If you order, we receive the email address you write from and whatever order details you include. That is used to send the licence and to answer questions. It is not sold, and not added to a mailing list. There is no newsletter.
Payments are processed by a third-party payment provider. Card details go to them and never touch this site. Their privacy terms apply to the payment itself.
The pages are static files served by a CDN. Like every web server, it sees the IP address and user agent that requested a page. No cookies are set by this site, and none are needed.
There is almost nothing to remove. To clear the licence key, use your browser's "clear site data". To have an order email deleted, write to the address below and it will be removed.
