Privacy Policy

Last updated: 5-August-2026

ConcreteBlocksCalculator (“we”, “us”, “our”) operates www.concreteblockscalculator.com. This policy explains what information we collect, why, and what control you have over it.

The short version

Our calculators do not collect anything. Every calculation runs inside your own browser. The dimensions, block sizes, and quantities you enter are never sent to us or to anyone else, and we never see them.

We do collect limited information through website analytics and our contact form. Those are covered below.

Information our calculators collect: None

All of our estimating tools — the Concrete Block Calculator, Retaining Wall Calculator, Block Weight Calculator, Fire Pit & Planter Calculator, and Concrete Slab Calculator — run entirely in your browser using JavaScript.

This means:

  • Your project dimensions are never transmitted to our servers
  • No calculation results are stored, logged, or saved
  • No account or sign-up is required
  • The calculators set no cookies and use no browser storage
  • Closing or refreshing the page clears everything you entered

Three optional features involve your own device or software, and are worth explaining:

  • Copy Results places your estimate on your device’s clipboard. This is handled by your browser and does not pass through us.
  • Print / Save PDF uses your browser’s own print function. No copy is sent to us.
  • Share Link (Concrete Block Calculator only) builds a web address containing the values you entered, so the calculator reopens with the same inputs. This link is created in your browser. We do not generate, store, or receive it. If you share that link, anyone with it can see the dimensions it contains, so treat it as you would any other link you send.

Information we do collect

Analytics. We use Google Analytics to understand how visitors find and use the site — which pages are viewed, how long people stay, and roughly where in the world traffic comes from. Google Analytics uses cookies and collects technical information including your IP address, browser type, device type, and referring page. This is used in aggregate to improve the site. We do not use it to identify individual visitors.

You can opt out using the Google Analytics Opt-out Browser Add-on, or by blocking cookies in your browser settings. Google’s own privacy policy is at policies.google.com/privacy.

Contact form. If you contact us, we collect the name, email address, and message you submit, so we can reply. We use this only to respond to your enquiry. We do not add you to a mailing list or sell your details.

Server logs. Like most websites, our hosting provider automatically records standard access logs, including IP addresses and request times. These are used for security and troubleshooting.

Cookies

The calculators themselves set no cookies. Cookies on this site come from Google Analytics, and your hosting or security provider may set essential cookies for the site to function.

You can block or delete cookies through your browser settings. Doing so will not affect the calculators, which work fully without them.

Sharing your information

We do not sell, rent, or trade personal information.

We share data only with the service providers that make the site work — currently our hosting provider and Google Analytics — and where we are legally required to do so.

How long we keep information

Contact form messages are kept only as long as needed to handle your enquiry and any follow-up. Analytics data is retained according to Google Analytics settings. Server logs are retained by our hosting provider under their own schedule.

Your rights

You may request a copy of any personal information we hold about you, ask us to correct or delete it, or ask us to stop using it. Contact us at [EMAIL] and we will respond within a reasonable period.

Because the calculators collect nothing, there is no calculator data to request or delete.

Children’s privacy

This site is intended for a general and professional audience. We do not knowingly collect information from children.

External links

Our pages may link to standards bodies, or reference material. We are not responsible for the privacy practices of other websites, and we encourage you to read their policies.

Changes to this policy

We may update this policy as the site changes. The revision date at the top will always show when it was last changed.
