This page carries advertising served by AdServerAI. When an ad is requested, AdServerAI records the placement, your approximate country and city, your browser's user-agent string, the referring page, and two irreversible hashes derived from your IP address and browser. These hashes are used to count unique views and to detect automated traffic. Your IP address itself is not stored, and the request is made without cookies.
Ads link through AdServerAI so the click can be counted, then forward to the advertiser's own site. Once you leave 21auth.com, the destination's privacy policy applies, not this one.
If you send an enquiry about this domain, the address and message you submit are stored so we can reply to you. That information is used for no other purpose, is not sold, and is not shared with advertisers.
