Privacy Policy
This Privacy Policy explains how DIY Material Math ("we", "us") handles information when you visit diymaterialmath.com (the "Site").
Information we collect
Calculator inputs. Calculations run entirely in your browser. The measurements you type into a calculator are not sent to us or stored by us.
Information you send us. If you email us, we receive your email address and the contents of your message, which we use only to reply.
Automatically collected information. Like most websites, our hosting provider and the third-party services described below may collect standard technical data such as IP address, browser type, device type, pages visited, referring page and the date and time of your visit.
Cookies and similar technologies
We and our partners may use cookies, web beacons and similar technologies to measure traffic, remember preferences and serve and measure advertising. You can block or delete cookies in your browser settings; the calculators will still work.
Advertising
We may use Google AdSense and other third-party advertising vendors to show ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this Site or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this Site and/or other sites on the Internet.
You may opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info/choices. For more on how Google uses data, see How Google uses information from sites or apps that use its services.
Analytics
We may use Google Analytics to understand how visitors use the Site. Google Analytics collects information such as pages visited and time spent on the Site. You can prevent Google Analytics from collecting your data by installing the Google Analytics opt-out browser add-on.
Affiliate links
Some pages contain affiliate links. If you click one, the retailer may set a cookie to attribute any purchase to us. See our affiliate disclosure.
How we use information
- To operate, maintain and improve the Site
- To respond to messages
- To measure traffic and display advertising
- To detect and prevent abuse or security problems
We do not sell personal information for money. Advertising cookies set by our partners may be considered a "sale" or "sharing" of personal information under some US state privacy laws.
Your privacy rights
Depending on where you live, including California, Colorado, Connecticut, Virginia and other US states, you may have the right to know what personal information is collected about you, to request deletion or correction, and to opt out of the sale or sharing of personal information and of targeted advertising. Because we hold very little information directly, most requests are best handled through the opt-out tools above. You can also contact us at contact@diymaterialmath.com. We honor Global Privacy Control signals where required by law. If you are in the European Economic Area, the UK or Switzerland, a consent message will ask for your choices before personalized ads are shown.
Children's privacy
The Site is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children.
Changes to this policy
We may update this policy from time to time. The effective date at the top of the page shows when it was last changed.
