This Privacy Policy explains how BuildCalcWorld ("we", "us", "the site") collects, uses, and protects information when you use our construction calculators, plugins and 3D models at buildcalcworld.com. By using the site you agree to the practices described below.

1. Information we collect

BuildCalcWorld is primarily a free set of online tools. Most calculators run entirely in your browser and we do not require you to create an account to use them. We may collect: (a) non-personal usage data such as pages visited, browser type, device and approximate location, gathered through analytics; (b) information you voluntarily provide, such as your email address if you subscribe to our newsletter or contact us; and (c) data stored locally in your browser (localStorage) to remember your calculator inputs and preferences.

2. Cookies and similar technologies

We use cookies and similar technologies to operate the site, remember your preferences, measure traffic, and serve advertising. Cookies are small text files stored on your device. You can disable cookies in your browser settings, but some features may stop working. You can also manage your consent at any time through the cookie banner.

3. Google AdSense and advertising

We use Google AdSense to display ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies (including the DoubleClick cookie) enables it and its partners to serve ads to you based on your visits to our site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings (google.com/settings/ads) or aboutads.info. For users in the European Economic Area, ads are served according to your consent choices.

4. Google Analytics

We use Google Analytics to understand how visitors use the site. Analytics cookies collect information such as how often you visit, which pages you view, and what other sites you came from. This information is used only to improve the site. You can opt out using the Google Analytics Opt-out Browser Add-on.

5. How we use information

We use collected information to: provide and improve our calculators and tools; respond to your enquiries; send the newsletter if you subscribed; analyze and improve site performance; and display relevant advertising. We do not sell your personal information.

6. Data retention and security

We retain personal data only as long as necessary for the purposes described here or as required by law. We apply reasonable technical and organizational measures to protect your information, although no method of transmission over the Internet is 100% secure.

7. Your rights

Depending on your location, you may have the right to access, correct, or delete your personal data, restrict or object to its processing, and withdraw consent. To exercise these rights, contact us at support@buildcalcworld.com.

8. Children's privacy

BuildCalcWorld is intended for general and professional audiences and is not directed at children under 13. We do not knowingly collect personal data from children.
