This Privacy Policy explains what information Geometry Formulas (https://geometry-formulas.net/) collects when you use the site and how it is used. We keep it simple: we collect as little as possible.
Information we collect
- Things you type into our tools. Numbers you enter into our calculators are worked out in your browser. We do not store them.
- Emails you send us. If you email us, we receive your email address and message and use them only to reply.
- Basic server logs. Like every website, our hosting provider automatically records technical data such as IP address, browser type and the pages requested. These logs are used for security and to keep the site running, and are kept for a limited time.
- Comments. If comments are open and you leave one, we store your name, email and comment. Your email is never shown publicly. WordPress may check your email against Gravatar to show a profile picture.
Cookies
We do not use advertising or tracking cookies. WordPress may set technical cookies if you leave a comment or log in. Our caching software may set a cookie needed for the site to work correctly.
Third-party services
- Google Fonts: fonts are loaded from Google servers, which receive your IP address to deliver them. See Google’s privacy policy.
- Hosting: the site is hosted by a web hosting company that processes server logs on our behalf.
If we add analytics or advertising in the future (for example Google Analytics or Google AdSense), we will update this page before they go live, explain what they collect and how to opt out.
Children
The site is educational and suitable for students. We do not knowingly collect personal information from children under 13. If you believe a child has sent us personal information, contact us and we will delete it.
Your rights
You can ask us what personal information we hold about you, and ask us to correct or delete it. Email hello@geometry-formulas.net. Depending on where you live (for example the EU, UK or California), you may have further rights under laws such as the GDPR or CCPA.
Changes to this policy
We may update this policy from time to time. The date at the top shows when it last changed.
