Privacy policy

Last updated: October 18, 2026.

Our calculators process the weights and repetition counts you enter in your browser. We do not ask you to create an account. If you choose to save a lift, the result is stored in your own browser's local storage, which you can clear through browser settings.

Hosting providers may collect routine technical server logs such as IP addresses, browser information and access times to maintain the site. We do not use this information to calculate your lift.

Analytics and advertising tools may be added later. This policy must be updated before those third-party scripts are activated, including details about cookies, data sharing, consent and privacy rights. This release ships with no analytics or advertising scripts configured.

Questions can be sent via our contact page.
