Privacy: what this site collects.

zero21.ai is a static site. It has no accounts, no forms that send data to a server, and no advertising. This page lists what is measured and how to opt out.

Analytics

Three tools run on every page. Vercel Web Analytics counts page views without cookies and stores nothing on your device. Vercel Speed Insights records page load timings (Core Web Vitals) for each visit, also without cookies. Google Analytics 4 sets first-party cookies to tell returning visits apart and reports aggregate usage. None of them is used for advertising, and visitor data is never sold or shared.

Error reports

If the page fails to load or a script throws, the browser sends a short technical description (the error message and file name, never anything you typed) to the same two tools so the fault can be fixed.

Booking and email

The Book a call button opens cal.com in a new tab. Anything you enter there is governed by the cal.com privacy policy. Email sent to partnerships@zero21.ai is read by Egemen Eres and kept only as long as the conversation needs.

Your choices

Block cookies in your browser and Google Analytics stops recognising return visits. Vercel Web Analytics never set any. To ask what is held about you, or to have it deleted, email partnerships@zero21.ai.
