Privacy Policy
This site is built to work without collecting personal data. Here's exactly what that means.
No personal data is collected. Every calculator on this site runs entirely in your browser, using plain JavaScript with no server round trip. Angles you type, results you view, and pages you visit are never transmitted to or stored on our servers, because there is no backend for them to be sent to in the first place.
No user accounts. The site has no login, no registration, and no user profiles of any kind. There is nothing to sign up for and nothing tied to your identity. Every visitor sees the same static pages, whether it's their first visit or their hundredth.
No cookies except required or performance cookies. We use Cloudflare's built-in analytics to understand aggregate traffic patterns: how many people visit, which pages are popular, which countries traffic comes from, all without tracking individuals or building personal profiles. This kind of analytics doesn't use tracking cookies or fingerprinting. It's aggregated at the network level before it ever reaches us. No advertising or cross-site tracking cookies are used anywhere on this site.
No third-party advertising. This site does not run ads and does not share data with ad networks, data brokers, or marketing platforms. There are no embedded trackers from social media platforms or ad exchanges on any page.
If you contact us through the contact page, the information you choose to include in that message, your name, email address, and message content, is used only to respond to you. That message is sent directly through your own email client rather than through a server we operate, so we only ever see what arrives in our inbox.
This site is entirely static: plain HTML, CSS, and JavaScript with no database and no user accounts. There is very little attack surface for a data breach to begin with. There's no password database to compromise and no personal information stored anywhere to expose.
If this policy changes, the update will be reflected on this page along with a new "last updated" date below. We don't expect it to change often, since the site's approach to data, collecting as little as possible, isn't likely to shift.
Questions about this policy, or about how any part of the site works, can be sent to contact@referenceangle-calculator.com.
