What information we collect
DIY Project Calc does not collect personal information from visitors. There is no login, no account creation, and no contact forms that store data on our servers. The numbers you enter into a calculator are processed in your browser and are never transmitted to us.
Use of cookies
Our advertising and affiliate partners — primarily Google AdSense and Amazon Associates — may set cookies on your device to measure ad performance and personalize advertising. We do not set our own tracking cookies. You can review Google's cookie practices in their privacy policy.
Third party advertising
This site is monetized through Google AdSense and the Amazon Associates program. These services may collect anonymous browsing data — such as pages visited, device type, and approximate location — to serve relevant ads and track affiliate referrals. We do not receive personally identifiable information from these partners.
How to opt out
You can manage or disable personalized ads from Google at adssettings.google.com. Most browsers also allow you to block third-party cookies entirely through their privacy settings.
