Ti84Calc (“we,” “our,” or “us”) operates the website ti84calc.net to provide a free, browser-based graphing calculator along with helpful learning resources. Your privacy matters to us, and this page explains exactly what data we collect, how we use it, and what rights you have as a visitor.
What We Never Collect
- You do not need to create an account to use our calculator.
- We do not save your calculations, formulas, graphs, or equations. What you enter stays on your screen and is never stored on our servers.
Information We May Collect
1. Standard Usage Data: We collect anonymous analytics such as pages visited, time spent on site, clicks, general region, and device type. This helps us understand how people use our tool and improve the experience.
2. Cookies: We use cookies to remember your calculator preferences — such as display mode and angle mode — so you don’t have to reset them on every visit. Cookies set during login checks do not contain personal or sensitive data and are automatically deleted when you close your browser.
Content You Upload
If you upload images or screenshots to our website, please make sure they do not contain location data (EXIF GPS). Other visitors may be able to download and extract that information from uploaded files.

We may work with third-party services including:
- Analytics providers to understand site usage
- Advertising networks to display relevant ads
These services may use cookies, web beacons, or similar technologies to collect information for their own purposes.
Google Advertising
Our site may display ads served by Google and its partners. Google may use cookies and similar technologies to show ads based on your browsing activity. You can opt out of personalized advertising at any time by visiting Google Ads Settings.
Data Retention
- Messages or support requests are retained only as long as needed for monitoring or support.
- Saved items are kept until you delete them yourself or they expire automatically.
