Privacy Policy

This policy describes how ztable.co ("this site") handles information when you visit.

Information we collect

This site does not require accounts and does not ask for personal information. All calculators run entirely in your browser — the numbers you enter are never sent to any server. Like most websites, our hosting may automatically log standard technical data (IP address, browser type, pages visited) which is used only in aggregate to understand traffic.

Cookies, analytics and advertising

The site may use cookies through analytics tools (such as Google Analytics) to measure aggregate usage, and may display advertising served by third parties such as Google AdSense. Third-party vendors, including Google, may use cookies to serve ads based on prior visits to this or other websites; you can opt out of personalized advertising in Google’s Ads Settings. You can also disable cookies in your browser — the site remains fully functional without them.

Downloads

The PDF, CSV and PNG downloads are static files — downloading them requires no registration and transmits no personal data beyond the standard server log entry.

Third-party links

Any external links lead to sites with their own privacy practices; this policy covers only ztable.co.

Changes & contact

Updates to this policy will be posted on this page. Questions: contact@ztable.co (see also the About page).
