PRIVACY POLICY

The short version

ProjectCalc is a calculator site. The calculators run entirely in your browser. Your inputs never leave the page and are never sent to any server, including ours.

We don't require an account, we don't collect email addresses, and we don't sell anything to anyone.

What we collect

Anonymous traffic statistics.Vercel Analytics records anonymized page views (which calculator pages were visited, from which country, and on what type of device) so we can see what's being used. No cookies, no personal identifiers, no tracking across other websites.

Server logs. Vercel automatically logs HTTP requests (IP address, user-agent, timestamp) for security and abuse prevention. These logs are retained for a short period and never combined with other data to identify individuals.

What we don't collect

We don't use Google Analytics, Facebook Pixel, fingerprinting scripts, or session recording. Apart from the advertising partners described below, no third-party analytics follows you across the web.

Advertising

ProjectCalc shows ads from third-party advertising partners to keep the calculators free. Our partners are Google AdSense and Journey by Mediavine (including its Grow script, which may set cookies for audience measurement and reader features).

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website 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 can opt out of personalized advertising by visiting Google Ads Settings and, for other vendors, at aboutads.info/choices.

Affiliate links

We may include affiliate links to retailers like Home Depot, Lowe's, or Amazon for products mentioned in calculator FAQs. Clicking these doesn't cost you anything extra; we may earn a small commission if you buy something. Affiliate clicks pass standard tracking parameters to those retailers — their privacy policies apply once you leave our site.

Your rights

Because we don't maintain user accounts or personal data, there isn't any data of yours for us to access, export, or delete. Local storage data is yours to manage in your browser.
