Privacy Policy

Overview

ConcreteBag ("we," "us") runs entirely in your browser. There is no user account system and no backend database — the calculators on this site read and process the numbers you enter locally on your device and do not transmit them to us.

Information we collect

We do not require or collect personal information to use the calculators. If you email us, we'll have whatever information you choose to include in that message. We may use privacy-focused analytics to understand aggregate traffic (e.g. which pages are visited), which does not identify you individually.

Cookies & advertising

This site may show ads served by Google AdSense. Google and its partners may use cookies, including the DoubleClick DART cookie, to serve ads based on your visits to this and other sites. You can opt out of personalized advertising by visiting Google Ads Settings or aboutads.info/choices. Third-party vendors, including Google, may also use cookies to serve ads based on your prior visits to this site or others.

Affiliate links

Material list links to Home Depot and Lowe's are, or may become, affiliate links. Retailers may set their own cookies once you click through to their site; we don't control those cookies and encourage you to review each retailer's privacy policy.

Your rights (GDPR/CCPA)

Depending on where you live, you may have the right to access, correct, or delete personal data we hold about you, and to opt out of the sale or sharing of personal information. Since we don't collect personal data through the calculators themselves, there is generally nothing tied to you to access or delete beyond anything you've emailed us directly.

Children's privacy

This site is not directed at children under 13, and we do not knowingly collect information from children.

Changes to this policy

We may update this policy from time to time. Changes take effect when posted on this page, with the "Last updated" date revised accordingly.
