What we collect, who we share it with, and the choices you have. Last updated 24 June 2026.
Construction Calc HQ ("we", "us") operates the website at constructioncalchq.com. This policy explains what data is collected when you use the site and how it is used. The calculators themselves run entirely in your browser — the dimensions and values you type are processed on your device and are not sent to or stored on our servers.
To keep the site free, we use third-party analytics and advertising services and we participate in affiliate programs. These partners may collect data through cookies and similar technologies, as described below.
We do not ask you to create an account, and we do not intentionally collect names, email addresses, or payment details through the calculators. The information collected automatically by us and our partners includes:
Cookies are small text files stored by your browser. We and our partners use them to measure traffic, remember preferences, and serve and measure advertising. You can block or delete cookies in your browser settings, and where required by law you will see a consent banner that lets you accept or reject non-essential cookies before they are set. Blocking cookies will not stop the calculators from working.
We use Google Analytics, a web-analytics service provided by Google LLC, to understand how visitors use the site in aggregate (for example, which calculators are most popular). Google Analytics sets cookies and processes data such as your IP address and usage activity. We use this data only to improve the site; it does not identify you to us personally.
You can opt out of Google Analytics across all websites by installing the Google Analytics Opt-out Browser Add-on. Google's handling of this data is described in Google's Privacy Policy and How Google uses information from sites that use its services.
We display ads served by Google AdSense. Google is a third-party vendor that uses cookies — including the DoubleClick/Google advertising cookie — to serve ads based on your prior visits to this and other websites. Third-party vendors and ad networks may also use cookies to serve ads based on your browsing.
If you are in a region that requires consent (such as the EU, UK, or Switzerland), Google ads on this site operate under a consent management prompt; ads may be non-personalized if you decline. See how Google uses cookies in advertising.
We also display advertising through Adsterra, an advertising network. Adsterra and its advertising partners may use cookies, web beacons, device identifiers, and your IP address to deliver and measure advertising, including interest-based ads. Adsterra's data practices and opt-out options are described in the Adsterra Privacy Policy. You can further limit interest-based advertising using the industry opt-out tools listed in the AdSense section above.
Some links on this site — including links on our Free Tools page and within guides — are affiliate links. If you click an affiliate link and make a purchase or take an action, we may earn a commission at no additional cost to you. We only link to products and services we consider relevant to construction estimating, and a commission never changes the price you pay.
Affiliate programs and merchants may set their own cookies to attribute a referral to us and may collect data about the click in accordance with their own privacy policies. Affiliate relationships do not influence the formulas, cost data, or recommendations presented on the site.
As an affiliate, Construction Calc HQ may earn from qualifying purchases and referrals. Advertising and affiliate commissions help keep the calculators free to use.
We do not sell your personal information for money. Note that some advertising-related data sharing can be considered a "sale" or "sharing" under certain US state privacy laws — see your choices below.
This site links to external websites, including our network of free tools and affiliate merchants. We are not responsible for the content or privacy practices of those sites. We encourage you to review the privacy policy of any site you visit.
Depending on where you live, you may have rights over your personal data:

Some browsers send a "Do Not Track" signal. There is no industry-standard response to this signal, so we do not respond to it; however, we do honor recognized opt-out mechanisms such as Global Privacy Control where applicable.
We retain aggregate analytics data only as long as needed to understand site usage. Data held by Google, Adsterra, and affiliate partners is retained according to their own policies, linked above.
This site is intended for a general, professional and DIY audience and is not directed to children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided personal information, please contact us so we can remove it.
The site is operated from the United States and our service providers may process data in the US and other countries. By using the site you understand that your information may be processed outside your country of residence.
We may update this policy from time to time. Material changes will be reflected by updating the "Last updated" date at the top of this page.
