Privacy Policy

What we collect

The calculators run entirely in your browser. The values you type — dimensions, prices, cut lists — are not sent to our servers; if you enable auto-save they're stored locally on your own device using your browser's localStorage, and you can clear them at any time. We do not ask for or store your name, email, or payment details unless you choose to email us.

Cookies and analytics

We use Google Analytics to understand which pages are useful, in aggregate. It sets cookies that collect anonymized usage data such as pages visited, approximate region, and device type. This helps us improve the guides; it does not identify you personally.

Google AdSense and advertising

This site displays ads served by Google AdSense. 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 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 aboutads.info. For more on how Google uses data when you use our partners' sites or apps, see Google's policy. Google's full data practices are described in the Google Privacy Policy.

Consent in the EEA, UK, and similar regions

Where required by law, ads and analytics that use cookies will only run after you provide consent through the consent prompt shown on your first visit. You can change or withdraw consent at any time.

Children's privacy

This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Your rights

Depending on where you live, you may have the right to access, correct, or delete personal data, or to object to certain processing. Because we hold almost no personal data, most requests relate to the third-party services above; we'll help you direct them appropriately.

Changes and contact

We may update this policy as the site or applicable law changes; the "last updated" date will reflect any revision. Questions? Reach us through the contact page. See also our terms of use and disclaimer.
