The calculators are plain JavaScript on this page. Your weights, reps and RPE are not sent anywhere — the calculation happens locally and nothing is stored on the server.
Anonymous, aggregated usage statistics with Plausible Analytics, self-hosted by the site owner (no Google, no third-party ad networks, no cookies, no device fingerprinting). Plausible stores no IP addresses: it derives a rotating daily hash that cannot be reversed into an identifier, and it does not track you across other websites. Recorded: page views and anonymous events (tool opened, calculation run, save button clicked, pricing viewed).
No cookie banner needed because no cookies are set. No email addresses collected at this stage. No personal data sold or shared. No advertising trackers.
Your browser's tracking protection blocks the statistics script without affecting the tools. Questions or removal request: use the contact details of the site owner.
Strength Tools — free calculators. Not for sale at this stage.
