Privacy Policy

Last updated: 14 November 2026

The short version

RepMaxLab's calculators run entirely in your browser. There are no user accounts, and the numbers you type into a calculator are never sent to or stored on our servers. We cannot see your lifts.

Information we collect

Calculator inputs: none. All calculations happen locally on your device using JavaScript.

Server logs: like almost every website, our hosting server automatically records standard technical information when your browser requests a page — such as your IP address, browser type and the page requested. These logs are used only for security, abuse prevention and basic traffic statistics, and are not used to identify individual visitors or combined with calculator activity (which we do not receive at all).

Email: if you contact us by email, we receive your email address and the contents of your message, and use them only to reply to you.

Cookies and advertising

This site may display advertising served by Google AdSense. Google and its partners use cookies to serve ads based on your visits to this and other websites. You can opt out of personalised advertising by visiting Google Ads Settings, and learn how Google uses data from sites that use its services at policies.google.com/technologies/partner-sites.

If analytics tools are used, they are configured to measure aggregate page traffic only (for example, how many people visited a calculator), not to track individuals across the web.

You can disable cookies in your browser settings at any time; every calculator on this site will still work.

Third-party links

Pages on this site may link to external websites. We are not responsible for the privacy practices or content of those sites.

Children's privacy

This site is a general-audience tool site and is not directed at children under 13. We do not knowingly collect information from children.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new "last updated" date.
