Privacy Policy

1. Overview

This Privacy Policy explains how TI-84Calc.com ("we," "us," or "this site") handles information when you visit. We built our calculator tools to run entirely in your browser, so most of what you type never reaches us at all. This policy covers what we do collect, how third-party advertising works on this site, and what choices you have.

2. Information we do not collect

We do not require an account to use our calculators. Equations, calculations, and any input you type into a calculator tool on this site are processed in your browser and are not transmitted to or stored on our servers.

3. Information collected automatically

Like most websites, our hosting and infrastructure providers automatically log standard technical information when you visit, which may include your IP address, browser type, device type, referring page, and the pages you view. This is common web server log data and is used for security, troubleshooting, and understanding overall site usage, not to identify you personally.

4. Cookies

Cookies are small text files stored on your device. This site may use cookies for the following purposes:

• Functionality: to remember basic preferences as you browse.
• Fonts: we load web fonts from Google Fonts, which may involve a request to Google's servers when a page loads.
• Advertising: as described in the section below, once advertising is active on this site.

You can control or delete cookies through your browser settings. Blocking cookies may affect how some parts of the site function.

5. Google AdSense and advertising

If you are located in the European Economic Area, the United Kingdom, or another region with similar requirements, we will seek your consent before placing non-essential cookies, including advertising cookies, in accordance with applicable law.

6. Analytics

We may use analytics services, such as Google Analytics, to understand how visitors use this site in aggregate. These services may use cookies and collect information such as pages visited, time on site, and general location at a city or regional level. This data helps us improve the site and is not used to identify individual visitors.

7. Children's privacy

This site is intended for a general audience that includes students of various ages, but it is not specifically directed at children under 13, and we do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can address it.

8. Your privacy rights

Depending on where you live, you may have rights regarding personal information collected about you, which can include the right to access, correct, delete, or restrict certain data, and the right to opt out of the sale or sharing of personal information for advertising purposes. To exercise any applicable rights, contact us using the details below.

9. Data security

We take reasonable measures to protect the limited information described in this policy, but no method of transmission or storage over the internet is completely secure, and we cannot guarantee absolute security.

10. Third-party links

This site links to external resources, including Texas Instruments, the College Board, ACT, Desmos, and GeoGebra, for reference and comparison. We are not responsible for the privacy practices or content of any third-party site.

11. Changes to this policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. Significant changes will be reflected here.
