Privacy Policy

Last updated: October 2026

Your privacy matters to us. This policy explains what information 1RMCalculator.net handles when you use the website.

Calculator data

Everything you enter into the calculators (weight, reps, units and selected formula) is processed in your own browser. We do not send it to our servers and we do not store it.

Information you send us

If you contact us through the contact form or by email, we receive your name, email address and message. We use this only to reply to you and do not share it with anyone else.

Log data and analytics

Like most websites, our hosting provider records technical data such as IP address, browser type and the pages requested. We may also use Google Analytics to understand how visitors use the site, for example which pages are popular. This helps us improve speed and content.

Cookies and advertising

We may display advertisements from Google AdSense. Google and its partners may use cookies to show ads based on your visits to this and other websites. You can manage or turn off personalised ads in Google Ads Settings (adssettings.google.com) or at aboutads.info. You can also block or delete cookies in your browser settings. Where required by law, we will ask for your consent before using non-essential cookies.

Third-party services

This site loads fonts from Google Fonts, so your IP address is sent to Google when the page loads. Our pages may also link to other websites. We are not responsible for their content or privacy practices.

Your rights

Depending on where you live (for example under GDPR or CCPA), you may have the right to access, correct or delete the personal data we hold about you. To make a request, email us at the address below.

Children

This website is not directed at children under 13, and we do not knowingly collect personal data from them.

Changes to this policy

We may update this policy from time to time. The date at the top shows when it was last changed.
