We built TI84Calc with privacy first. Here is exactly what we do and do not do with your data.
TI84Calc does not collect, store, or share any personal data. Your calculations run entirely in your browser. We do not use tracking cookies, advertising networks, or analytics that identify you personally. This is a calculator, not a data business.
TI84Calc ("we", "us", "our") operates the website at yourdomain.com. We provide a free, browser-based graphing calculator modeled after the TI-84 Plus CE for educational use.
If you have any questions about this Privacy Policy, you can reach us through our Contact page.
We do not collect personal information. We do not ask for your name, email address, phone number, or any other personally identifiable information to use our calculator.
All calculations you perform are processed entirely within your browser using JavaScript. Nothing you type into the calculator is sent to our servers. When you close the browser tab, your session data is gone permanently.
If you choose to submit a message via our Contact page, we collect only the information you voluntarily provide: your name, email address, and message. This information is used solely to respond to your inquiry and is not stored in a database or shared with third parties.
Like any website, our hosting server automatically records standard access logs when you visit a page. These logs may include your IP address, browser type, operating system, referring URL, and the pages you visited. This data is used only for diagnosing technical problems and monitoring server health. It is not linked to any personal identity and is deleted on a rolling basis.
TI84Calc does not use tracking cookies, advertising cookies, or third-party analytics cookies. We do not use Google Analytics, Facebook Pixel, or any other behavioral tracking service.
Your browser may store a session cookie that keeps the page functional during your visit. This cookie contains no personal information, is not used for tracking, and expires when you close your browser.
We do not embed third-party advertising, social media widgets, or tracking scripts on our calculator pages. We do not share your data with any third party for marketing or analytics purposes.
Our website is hosted on standard web infrastructure. Our hosting provider may process server logs as described above under their own privacy policy.
TI84Calc is an educational tool intended for users of all ages, including students under 13. Because we do not collect personal information from any users, we are compliant with the Children's Online Privacy Protection Act (COPPA). We do not knowingly collect any personal data from children.
Since we do not collect or store your personal data, there is no data to protect from a breach. Your calculation inputs never leave your device. For contact form submissions, messages are transmitted over HTTPS (encrypted connection) and handled with care.
Since we do not collect or store personal data, there is generally nothing to access, correct, or delete. If you submitted a contact form message and would like it removed, please contact us and we will delete it promptly.
Depending on your location, you may have additional rights under GDPR (EU), CCPA (California), or other applicable laws. We comply with all applicable privacy regulations.
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this page periodically. Continued use of the site after any changes constitutes your acceptance of the updated policy.
If you have any questions, concerns, or requests regarding this Privacy Policy, please use our Contact page. We aim to respond within 2 business days.
