Privacy Policy

Last updated: October 8, 2026

The short version

Gravel Order Calculator does not require an account and does not collect names, email addresses, or other personal information through its calculators. Calculations run entirely in your browser — the measurements you type never leave your device. We use Google Analytics to understand which features get used, and this page explains the cookies involved and the choices you have. If we begin displaying advertising, Google (and only Google, unless this policy is updated) may use advertising cookies as described below.

What we collect

Calculator inputs: nothing. Lengths, depths, materials, and prices you enter are processed locally in your browser and are not transmitted to us or stored.

Analytics data: We use Google Analytics 4 (measurement ID G-56RW1F3G1D) to count visits and feature use — for example, that a calculation was started or completed, which material was selected, or that a result was copied. These events describe what happened on the site, not who you are. Google Analytics sets cookies (such as _ga) to distinguish visits and sessions; Google may process IP addresses transiently as part of providing that service. We do not use analytics data to identify individual visitors, and we do not sell any data. Google's own handling of this data is described in the Google Privacy Policy.

Contact email: If you email us, we receive your email address and whatever you write, and use it only to respond.

Cookies we use

Analytics cookies (Google Analytics, described above). Advertising cookies apply only if and when this site displays ads; see the next section. This site sets no other cookies of its own. You can block or delete cookies in your browser settings at any time; the calculators work the same either way.

Advertising (Google AdSense)

We may display ads served by Google AdSense. If we do:

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to this site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info.

We do not currently use any third-party advertising vendor or ad network other than Google. If that changes, this policy will be updated to name the vendor or network, link to its site, and describe its opt-out options before its ads appear here.

Visitors in the EEA, UK, and Switzerland: Where consent is required for personalized advertising, ads will not be personalized for you without it. If this site serves personalized ads to visitors in those regions, it will first use a Google-certified consent management platform to request and record your choice.

Your choices

• Personalized ads: Google Ads Settings or aboutads.info.
• Analytics: block cookies in your browser, or install the Google Analytics Opt-out Browser Add-on.
• Everything: browser cookie controls apply to every cookie named above.

Changes to this policy

If we change what data is collected or which vendors are involved (for example, adding an ad network), we will update this page and its "Last updated" date before the change takes effect.
