Directive 2002/58/EC ("ePrivacy"), art. 5 (3), and art. 4 of the Luxembourg law of 30 May 2005.
This site sets no cookies and uses no analytics tool, no pixel and no third-party font service: the fonts are hosted with the site. That is why it shows no consent banner: there is nothing to consent to.
The only exception is the payment page, hosted by Stripe on its own domain: there Stripe sets the cookies strictly necessary for payment security and fraud prevention, which are exempt from consent. They are listed in Stripe's cookie policy.
The PDF Mirror software sets nothing either: its settings are saved in your Windows profile (%APPDATA%\PDFMirror), readable in plain text, and removed with it if you ask for that when uninstalling.
