Privacy Policy
Last updated: October 2026
SiteCals (“we,” “our,” “us”) respects your privacy. This policy explains what information we collect when you use sitecals.com, how we use it, and the choices you have. We keep it simple: this is a free calculator site with no user accounts, and we collect as little as possible.
Information We Collect
Information you provide directly
- Contact form submissions: when you message us, we receive whatever you include — typically your name, email address, and message text — so we can respond.
- Calculator inputs: values you type into calculators are processed in your browser to produce results. We do not store, transmit, or log your calculator inputs on our servers.
Information collected automatically
- Cookies and similar technologies: we use cookies for basic site functions (such as remembering your unit preferences) and, where enabled, for analytics and advertising. See “Cookies” below.
- Analytics: Google Analytics — we may use privacy-conscious analytics to understand aggregate usage (for example, which calculators are most visited) so we can improve the site. This data is aggregated and does not identify you personally.
- Log data: our hosting provider may automatically log standard technical information such as IP addresses, browser type, and pages visited, for security and operational purposes.
How We Use Information
We use the information we collect to:
- Operate and maintain the site and its calculators.
- Respond to messages you send through the contact form.
- Understand aggregate usage patterns and improve our tools and content.
- Display advertising that keeps the site free (Google AdSense — see “Advertising” below).
- Detect and prevent abuse, spam, or security threats.
We do not sell your personal information. We do not use your contact-form messages for marketing.
Advertising
SiteCals is free to use and supported by advertising. Google AdSense — Our advertising partners may use cookies to serve ads based on your prior visits to this and other websites. You can learn how Google uses data in advertising at Google’s Privacy & Terms page, and you may opt out of personalized advertising through Google’s Ads Settings.
Cookies
Cookies are small text files stored on your device. We use:
- Essential cookies — required for basic site features such as unit preferences. The site cannot function properly without these.
- Analytics cookies — help us understand aggregate site usage (Google Analytics).
- Advertising cookies — set by our ad partners to serve relevant ads (Google AdSense).
You can control or delete cookies through your browser settings. Note that disabling essential cookies may affect calculator functionality such as unit switching.
Third Parties
We share information only as needed to run the site:
- Hosting and security providers — technical data necessary to serve and protect the site.
- Analytics providers — aggregated usage data (Google Analytics).
- Advertising partners — cookie-based ad delivery (Google AdSense).
- Legal compliance — if required by law or to protect our rights and the safety of our users.
Your Rights
Depending on where you live, you may have the right to request access to, correction of, or deletion of personal information we hold about you (for example, a contact-form message). To make such a request, contact us through the Contact page and we will respond within a reasonable timeframe.
Children’s Privacy
SiteCals is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has submitted personal information through our contact form, please let us know and we will delete it.
Changes to This Policy
We may update this policy from time to time. When we do, we will revise the “Last updated” date above. Continued use of the site after changes take effect constitutes acceptance of the updated policy.
