Privacy Policy

Last updated: September 2025

Welcome to TI-84 Online. We respect your privacy and are committed to protecting it. This Privacy Policy explains how we collect, use, and safeguard your information when you visit our website.

1. Information We Collect

We do not require users to create an account or provide personal information to use the calculator. We may collect non-personal data such as browser type, operating system, and anonymous usage statistics to improve user experience.

2. Cookies and Local Storage

We use local storage strictly to save your calculator preferences, such as zoom level and color themes. These are stored locally on your device and are not transmitted to our servers.

3. Third-Party Services

We may use third-party services like Google Analytics and Google AdSense. These third parties may use cookies or web beacons to collect non-personal information about your visits to provide relevant advertisements and analyze traffic. You can opt out of personalized advertising by visiting Google's Ad Settings.

4. Data Security

Because the emulator runs client-side in your browser, your mathematical calculations and data are never sent to or stored on our servers. We maintain standard security measures to protect the hosting environment.

5. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
