Google Analytics

We use Google Analytics 4, a service provided by Google, to see how many people visit and which pages are useful. Its script loads from www.googletagmanager.com on every page except the "page not found" page.

When you open a page, the script sends Google:

• the address and title of the page, and the page that referred you;
• your browser, device type, operating system, screen size and language;
• an approximate location that Google works out from your IP address (Google says Google Analytics 4 does not log or store IP addresses);
• a random identifier stored in a cookie, so repeat visits can be counted as one visitor;
• some interactions, such as scrolling, clicks on links to other sites, and the fact that you started using a form such as a calculator. The numbers you type into a calculator are not part of the page address and we do not send them.

We use these statistics only to understand readership. We do not use them for advertising, and we have not turned on Google signals or linked the property to Google Ads. Google may process the data in the United States and other countries. Google explains how it uses data from sites like this one at policies.google.com/technologies/partner-sites.

Cookies

Google Analytics sets two first-party cookies as soon as a page loads. There is no consent banner on this site.

• _ga holds the random identifier that tells visitors apart.
• _ga_XYVLBGS3CQ holds the state of your current visit.

Google sets both to last 2 years. Some browsers, including Chrome, keep cookies for at most 400 days.

How long Google keeps it

User-level and event-level data is kept for 14 months, counted from your last visit. Aggregated reports, such as visit totals, are not subject to that limit.

How to opt out

Install Google's opt-out browser add-on (desktop browsers only), or use a content blocker that blocks requests to www.googletagmanager.com and google-analytics.com. Blocking cookies alone is not enough: Google Analytics can then no longer recognise you between visits, but the page may still send visit statistics. You can delete cookies already set in your browser's settings.

What stays in your browser

The chest tracker saves your chest count in your browser's local storage so it is still there next time. We never receive it. Clear this site's data in your browser to remove it.

Hosting

The site is served by Cloudflare. Like any host, Cloudflare processes your IP address, the page requested and your browser type in order to deliver and protect the site.
