• Make automated decisions that affect your rights or interests

3 Cookies and Tracking Technologies

USCalculators.com uses cookies and similar technologies. Here is a breakdown of what we use and why:

• Essential cookies — required for the site to function correctly (e.g., security cookies, session management). These cannot be disabled.
• Analytics cookies — we use Google Analytics to understand aggregate traffic patterns. These cookies collect anonymous usage data.
• Advertising cookies — if advertising is enabled on the site, our ad partners (such as Google AdSense) may place cookies to serve relevant ads based on your browsing history.
• Preference cookies — we may store your calculator preferences (such as unit settings) in your browser’s local storage. This data stays on your device.

You can control or delete cookies through your browser settings. Note that disabling certain cookies may affect site functionality. For more information about cookies and how to manage them, visit allaboutcookies.org.

4 Third-Party Services

We use the following third-party services that may collect data according to their own privacy policies:

• Google Analytics — website traffic analysis. Google Privacy Policy
• Google AdSense — advertising delivery. Google Ads Privacy
• Cloudflare — CDN, security, and performance. Cloudflare Privacy Policy

5 Advertising and Analytics

USCalculators.com may display advertisements served by Google AdSense and similar networks. These ad networks may use cookies and web beacons to collect information about your visits to this and other websites in order to provide targeted advertisements.

You may opt out of personalized advertising by visiting:

We use Google Analytics with IP anonymization enabled. This means Google Analytics truncates your IP address before storing it, preventing us from identifying you individually from analytics data.

We implement industry-standard security measures to protect the limited data we collect:

• HTTPS encryption — all data transmitted between your browser and our site is encrypted using TLS
