Privacy Policy

Semteo ("the site") respects your privacy. Effective 2026-10-25.

1. Information we collect

There are no accounts. Values you enter into calculators are processed in your browser only and are never sent to or stored on our servers. Share buttons share the page address only, never your inputs.

2. Cookies and advertising

To cover running costs the site may show ads from third parties such as Google AdSense. Ad providers may use cookies to show ads based on your previous visits to this and other websites.

• You can turn off personalized ads in Google Ads Settings.
• How Google uses data: policies.google.com/technologies/partner-sites

You can block cookies in your browser; the calculators still work.

3. Server logs

Our hosting provider (Cloudflare) may automatically log IP addresses and browser details for security and operations.
