This policy explains what information Right Triangle Calculators ("we", "us") handles when you use righttrianglecalculators.com (the "site"), and why.
Calculations stay on your device
All calculations happen in your web browser. The values you type into a calculator are not sent to us or to anyone else, and we don't store them.
After you solve a triangle, the page adds your input values, units, and angle mode to the address bar so that the link reopens the same triangle. This link stays in your browser history like any other URL. If you share it, anyone who opens it will see those values. The Copy shareable link button copies it to your clipboard only when you click it.
No accounts, no tracking cookies
The site has no user accounts or sign-up forms. We don't use advertising or analytics cookies, tracking pixels, or any other way to follow you across websites.
If you choose light or dark mode with the theme toggle, your browser saves that choice in local storage on your device so the site remembers it on your next visit. The value never leaves your browser. You can remove it by clearing your browser's site data.
Server logs
Like almost every website, the site is served by a hosting provider whose servers automatically record basic technical information about each request. This includes your IP address, browser type, the page requested, the referring page, and the time of the request. These logs are used only to deliver the site, keep it secure, and diagnose problems. We don't use them to identify individual visitors, and the provider keeps them only for a limited time.
When you email us
If you contact us, we receive your email address and whatever you include in your message. We use this only to reply and to fix any problem you report. We don't add you to a mailing list, and we don't sell or share your details.
Third-party services
Fonts and all other site files are served from our own domain, so opening a page doesn't send requests to third-party services. Links to other websites are governed by those sites' own privacy policies.
Children's privacy
The site is suitable for students of all ages. It doesn't knowingly collect personal information from anyone, including children under 13. If you believe a child has sent us personal information by email, contact us and we will delete it.
Your rights
Depending on where you live, laws such as the GDPR (EU/UK) or the CCPA (California) may give you the right to access, correct, or delete personal information we hold about you, or to object to how we use it. The only personal information we could hold is email correspondence. To make a request, email us and we will respond within the time the law requires. We don't sell personal information.
Changes to this policy
If our practices change, for example if we add analytics or advertising, we will update this page and the "last updated" date above before the change takes effect.
