Welcome to Online TI-84 (onlineti84.com). This Privacy Policy explains what information we collect when you use our website, and what we do with it. We keep this simple on purpose: our calculator is a free tool, and it does not need your personal information to work.
1. Information We Do Not Collect
Our calculator runs entirely in your browser. You do not need to create an account, sign in, or provide your name, email address, or phone number to use it. The functions and expressions you type into the calculator are processed on your own device, and we do not store, record, or transmit them to our servers.
2. Information Collected Automatically
Like most websites, our hosting provider may automatically record basic technical information when you visit, such as your IP address, browser type, device type, pages visited, and the time of your visit. This information is used only to keep the website running, secure, and fast. It is not used to identify you personally.
3. Cookies
Our website may use cookies, which are small files stored on your device. Essential cookies help the website load and function properly. In the future, if we display advertisements (for example through Google AdSense), advertising partners may use cookies to show relevant ads and measure their performance. You can block or delete cookies at any time through your browser settings, though some parts of the website may not work as smoothly without them.
4. How We Use Information
Any technical information collected is used only to operate, maintain, and improve the website, protect it against abuse, and understand in general terms how visitors use it (for example, which pages are popular). We do not sell, rent, or trade your information to anyone.
5. Third-Party Services
Our website may link to third-party websites or display third-party advertisements. Those third parties have their own privacy policies, and we are not responsible for their practices. We encourage you to read the privacy policy of any website you visit through a link on our site.
6. Children’s Privacy
Our calculator is used by students for learning, and we do not knowingly collect personal information from children under the age of 13. Because the calculator requires no account and no personal information, children can use it without sharing anything about themselves. If you believe a child has shared personal information with us through our contact page, please contact us and we will remove it promptly.
7. Data Security
We take reasonable steps to protect the website and any technical information associated with it. However, no method of transmission over the internet is completely secure, and we cannot guarantee absolute security.
8. Your Choices
You can use our calculator without providing any personal information. You can disable cookies in your browser settings at any time. If you contact us by email, we will use your message only to respond to you and will not share it with others.
9. Changes to This Policy
We may update this Privacy Policy from time to time, for example if we add new features or advertising services. The “Effective Date” at the top of this page will be updated when changes are made. We encourage you to review this page occasionally.
