Privacy Policy

Last updated June 5, 2026

Short version: this is a free calculator site. We don’t want your personal data and we don’t collect it.

Your calculations stay in your browser

Every calculator on this site runs entirely in your web browser. The numbers you type are used to do the math on your own device — they are never sent to us, never saved, and never shared. Close the tab and they’re gone.

What third parties might see

• Fonts: we load typefaces from Google Fonts, which may log standard request data such as your IP address under Google’s privacy policy.
• Traffic measurement: we may use a privacy-friendly, cookie-free analytics tool (such as Cloudflare Web Analytics) to see how many people visit. It does not use cookies and does not collect personal information.
• Advertising: this site does not currently show ads. If that changes, third-party ad vendors (such as Google) may use cookies to serve ads; you can opt out at google.com/settings/ads, and this page will be updated to say so.

Affiliate links

Some outbound “where to buy” links may be affiliate links. If we earn a commission it comes at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. Any such relationship is disclosed on the page where the link appears.

Your rights (CCPA / GDPR)

We do not sell personal information, and because the calculators run locally we hold essentially none. If you have a privacy question, email privacy@renoprojectcalc.com.
