What you enter
Your measurements stay in your browser. The calculators run on your device. What you enter is not sent to us or anyone else, not saved, and is gone when you close or reload the page.
Visits
Page views are counted with Umami, an open-source analytics tool we host ourselves on our own server: its script loads from analytics.answermend.com, the only address outside this site that the pages contact unless you accept Google Analytics (below). It records the page, the referring site, browser, device type and country. It sets no cookies and does not store your IP address. It never sees what you enter.
Hosting
The site is hosted by Hostinger, whose servers keep standard access logs (IP address, time, page requested) for security and running the service. The pages use your device’s own fonts; nothing is loaded from a font service.
Saved in your browser
Two small settings are saved in your own browser (local storage), never sent to us: your light/dark choice (ss-theme) and your cookie choice (ss-consent, below). They are not cookies; clearing the site data in your browser removes them. Your measurements are never saved.
Google Analytics (only if you accept)
To see how many people visit and how they find us, we’d also like to use Google Analytics 4, run by Google. The banner asks first. Before you choose, and if you press Decline, your browser doesn’t load it: nothing is sent to Google and no Google cookie is set.
If you press Accept, your browser loads Google’s tag from googletagmanager.com and sends Google Analytics, for each page you open:
- the page address and the address of the page that linked you here, both without any query string or
#part, - the page title, your screen size and browser language, and your browser, operating system and device type,
- nothing else.
Your measurements are never part of it. Google works out an approximate location (country, region and city) from your IP address. For visitors in the EU, the UK and Switzerland, Google says it drops the IP address after that lookup and doesn’t store it (Google’s note, read on November 11, 2026).
Google Analytics then sets two first-party cookies on this site: _ga, a random ID that tells repeat visits apart, and _ga_T7LYPJ0K86, which keeps one visit together. Both last 2 years (Google’s cookie list, read on November 11, 2026).
We set it up with Google signals and ad personalization off and ad storage denied (we don’t run ads), and Google keeps the data for 14 months. In our Google Analytics account settings, sharing with other Google products is off; sharing for Google’s technical support, its account specialists and anonymous benchmarking is on. Google handles the data as described in the Google Privacy Policy.
Cookies and your choice
SportSizing itself sets no cookies, and Umami sets none. The only cookies are Google Analytics’ two, and only after you press Accept in the banner. If you press Decline, or never choose, Google Analytics doesn’t load. To change your choice, use Cookie settings at the bottom of any page: Decline deletes the _ga cookies, turns Google Analytics off and, if it was running, reloads the page so nothing more is sent. Your choice is kept in your browser’s local storage (ss-consent), not in a cookie.
