Privacy Policy

Last updated: November 7, 2026

This policy explains what information TI84CalcHub (“we”, “us”) collects when you use ti84calchub.com, how we use it, and the choices you have.

Information we collect

Information you give us

If you email us or use the contact form, we receive your name, email address and message. We use this only to reply to you and do not sell it or add you to a mailing list.

Calculator data in your browser

The calculator saves your lists, functions, matrices and settings in your browser’s local storage so your work is still there next time. This data stays on your device. It is not sent to our servers, and you can delete it at any time by clearing your browser’s site data.

Information collected automatically

Like most websites, our hosting provider and analytics tools may log basic technical data such as your browser type, device, pages visited and approximate location based on your IP address. We use this to keep the site working and to understand which pages are useful.

Cookies and advertising
