What we collect
The Square Footage Calculator runs entirely in your browser. The dimensions you enter, the shapes you select, and the results that are calculated never leave your device. Nothing about your project is transmitted to our servers or any third party.
Standard server logs may record your IP address, browser user agent, and the page you visited. These logs are kept for up to 30 days and are used only to diagnose technical problems. They are not used for advertising or profiling.
Cookies
This site sets cookies for two things: measurement and advertising. Google Analytics 4 sets cookies (_ga and _ga_*) that count visits and record which pages get opened. Google AdSense and its partners set their own to serve and measure ads. Neither carries anything you type into a calculator. You can block both in your browser and the calculators work exactly the same without them. You can also change your choice at any time with the Cookie settings link in the footer.
Third-party services
Web fonts are served from this site's own domain, so loading a page opens no connection to an outside font provider. The third-party code that does load is Google Analytics and Google AdSense.
We embed no social-media share trackers, chat widgets or remarketing pixels.
What happens to the numbers you type
Nothing leaves your browser. Every calculator on this site runs entirely in the page: the dimensions, waste percentages and costs you enter are held in the browser's memory while you use the tool and are gone when you close the tab. They are never transmitted to us, never written to a database, and never stored on your device. The site is a set of static files with no server-side application behind it, so there is nowhere for that data to go even if we wanted it.
There is no account system, no login and no form on this site that stores what you type. If you contact us by email, we hold that email in the mailbox it was sent to for as long as we need to answer it, and nowhere else.
Advertising and how to limit it
This site carries advertising through Google AdSense, which is what keeps the calculators free to use. Google and its partners may set cookies to serve and measure those ads, and may personalise them based on your prior browsing. We do not receive or store the data those cookies collect.
You can limit this. Google's Ads Settings let you turn off ad personalisation across Google services, and most browsers allow you to block or delete third-party cookies entirely. Doing either will not affect the calculators — they run in the page and need no cookies to work.
We use Google Analytics 4 to count visits and see which calculators get used. It records the page you opened, an approximate location derived from your IP address, and your device and browser type. It does not receive the dimensions, waste percentages or costs you enter, because those never leave the page. You can opt out with Google's Analytics Opt-out Browser Add-on or by blocking cookies. Our host also keeps standard server request logs, as any web host does, and we do not use them to build any profile of visitors.
Your rights
Because we do not store personal data, there is generally no information for us to access, correct, or delete on your behalf. If you have a specific question about data this site might hold about you, contact us through the contact page.
Changes to this policy
If we change how the site collects or uses data, we will update this page and revise the "last updated" date at the top.
