What ZEUS collects
ZEUS is a static website. It sets no cookies, runs no analytics or advertising scripts and embeds no third-party trackers. The web server and the content-delivery network in front of it (Cloudflare) keep standard access logs (IP address, requested URL, user agent, time) for security and capacity purposes for a limited period.
Calculators
Every calculator runs entirely in your browser. The values you enter are not transmitted to ZEUS or to anyone else and are not stored after you leave the page.
If you write to [email protected], ZEUS keeps the correspondence for as long as needed to handle it and does not share it, except where required by law.
External links
Pages link to sources (regulators, press, retailers, datasets). Those sites have their own privacy practices.
Changes
