Privacy

This site is built so you can use it without telling us who you are. This page explains what that means in practice.

What we ask for

We don’t ask for your name, your email address or an account. There is nothing to sign up for.

Our tools

The test finder and the free testosterone calculator run in your browser. The answers and values you enter stay on your device. They are not sent to us, we don’t store them, and they are not put in the page address. We treat them as confidential, because we never receive them.

Counting visits

We use Google Analytics 4 to see which pages people read and which test links they click. It records pages viewed, clicks on test links, your general location, your device and how you reached the site, and it sets cookies to do this. Google receives this data, including the address of each page you view, and those addresses can show which topic you were reading about.

We have turned off Google’s advertising features for this site, and we don’t send your finder answers or calculator values. If your browser sends a Global Privacy Control signal, we don’t load Google Analytics at all. You can also use Google’s opt-out add-on.

When you follow a link to a seller

Buy links go through an address on this site and then to the seller, by way of an affiliate network (CJ Affiliate). Once you leave this site, the seller and the network handle your information under their own privacy policies. They may set cookies to record that you came from us, so we can be credited for a purchase. Your order, payment and lab results are handled by the seller and its lab, not by us. See the affiliate disclosure.

Technical logs

Like most websites, the service that hosts this site may record technical details such as your IP address, browser type and the pages requested. These logs are used to run and secure the site.

Changes

If we change what the site collects, we will update this page and its date.
