popunderads.io sets no cookies, runs no analytics and loads no third-party scripts. A visit leaves only the standard server log that a web host keeps, and nothing about you is sold or shared with the networks in the popunder ad networks comparison.
What the server logs
Serving a page creates a log line with the IP address, time, requested URL, browser user-agent and referrer. The hosting provider keeps these for security and error diagnosis for a limited period. They are not combined with any other data.
Fonts and images
Typefaces, styles and images load from popunderads.io itself. Rendering a page sends no request to Google Fonts or any other font service.
Links you choose to follow
Outbound links to networks, standards bodies and review sites hand you to those parties, each with its own privacy policy. The AdsCompass sign-up buttons carry UTM tags naming the button you used, and the advertising disclosure explains them. This site passes nothing about you beyond the referrer header your browser sends.
Email you send
Messages to the addresses on the contact page stay in a mailbox. Their only uses are replying to you and, for corrections, checking the source you sent; no mailing list is ever built from them.
Your rights
The GDPR and similar laws let you request a copy of your personal data, have it corrected or deleted, and complain to a supervisory authority. The site keeps no visitor profile, so a request usually concerns email only. Write to [email protected].
Children
The subject is advertising technology for people who work in it. The site is not aimed at children and collects nothing from them on purpose.
Changes
If analytics or a cookie is ever added, this page changes first and the date above moves with it. The terms of use cover how the content may be used, the about page who runs the site, the methodology how figures are checked, and Christoph Trappe's page who writes them.
