By using our free TI-84 Plus CE online calculator, you agree to these terms.

1. Acceptance of Terms

By accessing or using the TI-84 Plus CE Online Calculator ("the Service") provided at this website, you agree to be bound by these Terms and Conditions. If you do not agree, please do not use the Service.

2. Description of Service

We provide a free, browser-based emulator of the Texas Instruments TI-84 Plus CE graphing calculator. This is an educational tool designed to help students with mathematics, statistics, algebra, calculus, and exam preparation (SAT, ACT, JEE, CBSE, AP, IB, etc.).

3. Free Forever Policy

The Service is and will always remain 100% free for all users. There are no premium plans, no paid features, no subscriptions, and no hidden charges — ever.

4. No Warranty & Educational Use Only

The TI-84 Plus CE Online Calculator is provided "as is" without any warranties. While we strive for 100% accuracy and match the official Texas Instruments OS (currently version 5.7.2.0016 as of November 2025), we do not guarantee identical results in every scenario. This tool is intended for educational and practice purposes only.

5. Exam & Testing Compliance

Our emulator is accepted by most testing authorities (College Board, ACT, IB, CBSE, JEE, etc.) because it is a faithful replica with no external solving capabilities. However:

It is your responsibility to confirm with your school, teacher, or testing center that online emulators are permitted.
We are not liable if a proctor or institution rejects the use of browser-based calculators.

6. Prohibited Activities

You agree not to:

Use the Service for cheating or academic dishonesty
Attempt to modify, hack, or reverse-engineer the emulator
Distribute malware or harmful code through shared programs
Use automated scripts or bots to overload the Service
Remove or hide the calculator interface for unauthorized use

7. Program Sharing & .8xp Files

You may download and upload TI-BASIC programs (.8xp files). You are solely responsible for the content of programs you create or share. We do not moderate uploaded files but reserve the right to remove any harmful or inappropriate content.

8. Privacy & Data

We collect zero personal data.
No email, no login, no cookies, no tracking, no analytics. Your calculations and programs stay only in your browser (or saved locally when you download them).

9. Intellectual Property

The TI-84 Plus CE is a trademark of Texas Instruments. This website is an independent educational project and is not affiliated with, endorsed by, or sponsored by Texas Instruments. The emulator is built using publicly available ROMs and open-source emulation technology for non-commercial, educational use.

10. Limitation of Liability

We are not responsible for:

Any academic consequences from using this tool
Loss of saved work due to browser crashes or clearing cache
Internet connectivity issues affecting performance
Any indirect or consequential damages

11. Changes to Service

We reserve the right to modify, suspend, or discontinue the Service at any time without notice. We will always try to keep it free and available, but we do not guarantee 100% uptime.

12. Updates to Terms

We may update these Terms from time to time. The updated version will be indicated by the “Last updated” date at the top. Continued use of the Service after changes means you accept the new terms.
