Privacy Policy
Short version: the calculators run entirely in your browser, this site does not ask you to create an account, and the only third party involved is the advertising network.
What the calculators do with your numbers
Nothing leaves your device. Every calculator on this site is JavaScript that runs in your browser. Your weight, height, age, training numbers and results are never sent to a server, never stored, and never seen by anyone including me. Close the tab and they are gone.
What we collect
This site has no accounts, no login, no newsletter sign-up form, and no comment system. We do not ask for your name, your email address, or any other personal detail.
Standard web server logs may record the usual technical information — IP address, browser type, pages requested, timestamp — for the purpose of keeping the site running and secure.
Advertising
This site is supported by advertising. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and other sites on the internet.
- You can opt out of personalised advertising by visiting Google Ads Settings.
- You can opt out of a third-party vendor's use of cookies for personalised advertising by visiting aboutads.info.
If you are in the European Economic Area, the United Kingdom or Switzerland, you will be asked for consent before personalised advertising cookies are set, and you can change or withdraw that consent at any time.
Analytics
If site analytics are used, they are configured to measure aggregate traffic only — which pages are read, roughly where visitors come from — and not to identify individuals.
Children
This site is intended for adults. It is not directed at children under 13 and we do not knowingly collect information from them.
Your choices
You can block or delete cookies in your browser settings. The calculators will continue to work normally with cookies disabled, because they do not use them.
Changes
If this policy changes, the date at the top of this page changes with it.
