Privacy Policy

Last updated: October 13, 2026

This policy explains what information Square Footage Calculator ("we", "us") collects when you visit calcsquarefootage.com, how we use it and the choices you have. The short version: we do not ask for your name, we do not sell personal information, and the numbers you enter into our calculators never leave your browser.

Information we collect

Calculator inputs

Our calculators run entirely in your browser. Measurements and results are not sent to us, saved on a server or stored in cookies.

Usage data from Google Analytics

We use Google Analytics 4 to understand which pages people use, so we can improve them. Google Analytics collects information such as the pages you view, how long you stay, the site that referred you, your approximate location (city or region), and your device, browser and operating system. We cannot identify you from this data.

Google says it does not log or store IP addresses from users in the EU, Switzerland or the UK and uses them only to estimate location before discarding them (Google Analytics privacy controls). Our Google Analytics data is kept for no longer than 14 months.

To learn how Google uses this data, see How Google uses information from sites or apps that use our services.

Hosting logs

The site is hosted on Firebase Hosting, a Google service. Like most web hosts, it receives the IP address of each request, which Google uses to detect abuse and report usage. Google states that Hosting keeps IP data for a few months (Firebase privacy information).

Emails you send us

If you email us, we receive your email address, your name if you include it and anything in your message. We use this only to reply and to fix what you report. We keep emails for as long as needed to deal with your message and then delete them on request.

Cookies

We do not set our own cookies. Google Analytics sets these first-party cookies:

Cookie Purpose Expires
_ga Distinguishes visitors 2 years
_ga_<ID> Keeps session state 2 years

Source: Google Analytics cookie usage. You can block or delete cookies in your browser settings, and the calculators will still work.

Some pages may link to products or retailers through affiliate programs. If you click one, the retailer or affiliate network may set its own cookies on its site to credit us for a sale. Those cookies are governed by that company's privacy policy, not ours. See our affiliate disclosure.

We link to sources such as government agencies and standards bodies. We are not responsible for their privacy practices, so please read their policies.

How we use information

  • To run, secure and improve the site and its calculators.
  • To see which pages and tools are useful.
  • To answer your emails.

We do not sell or rent personal information, and we do not use it to build advertising profiles.

Your choices

  • Install the Google Analytics Opt-out Browser Add-on to stop Google Analytics from collecting data about your visits.
  • Block or clear cookies in your browser.
  • Email us to ask what information we hold about you, or to have your emails corrected or deleted.

Depending on where you live, privacy laws such as Canada's PIPEDA, the EU and UK GDPR or US state laws like California's CCPA may give you rights to access, correct or delete your personal information, or to object to its use. To use any of these rights, email us. If you are in Canada and are not satisfied with our answer, you can contact the Office of the Privacy Commissioner of Canada.

Where data is processed

We operate from Canada. Google may process analytics and hosting data in the United States and other countries where it runs servers.

Children

This site is meant for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children. If you think a child has sent us personal information, email us and we will delete it.

Changes to this policy

If we change how we collect or use information, we will update this page and the date at the top.
