Privacy Policy

At ti84calc.net, your privacy comes first. Our Calculator Emulators run entirely in your browser, so your calculations and data never leave your device. We don’t store, track, or share your data, and we follow important privacy laws like the GDPR, CCPA, COPPA, and PIPEDA to protect you.

What We Do (and Don’t) Collect

We don’t ask for or keep any personal information like your name, email, address, or phone number. Our calculators work without registration or login. We collect only minimal, anonymous information to improve the site:

• Your browser type and device info
• Your country-level location
• Which calculator tools or features you use
• Performance data (like if something crashes)

This information helps us fix bugs and make our site better. None of it identifies you personally.
Legal Basis (GDPR): Our legal basis for collecting this anonymous usage data is our legitimate interest in maintaining and improving the functionality, performance, and reliability of the ti84calc.net website.

How We Collect That Basic Info

We collect usage data in two main ways:

• Automatically: When you visit the site, we log some basic info (like browser type, device, or IP address).
• Cookies & Local Storage: These are small files saved on your browser that:
  • Keep your settings during your session
  • Help us improve performance (not ads!)
  • Store temporary calculator data

You can turn off cookies in your browser, but some site features may not work as smoothly.
Third-Party Tools: We may use trusted partners like Cloudflare (for security) and privacy-respecting analytics tools (such as Plausible or a self-hosted alternative) to understand how people use our site. These partners follow strict data privacy standards and never receive personal information.

Children's Privacy (COPPA Compliance): We do not knowingly collect personal information from children under 13. If you're under 13, you can use the calculators freely without sign-ups or profiles. If we ever learn we've accidentally collected personal data from a child, we’ll delete it right away. Parents can contact us at info.ti84calc@gmail.com.

Sharing Info: We don’t sell your data. We may share limited, non-personal data (like IP addresses) with trusted service providers who help us run the site. If legally required (e.g., by a court), we’ll share only what’s necessary.

For Schools and Educational Use: No student data is collected or stored, making our tools safe for classrooms and exams.
How We Protect Your Data: We use HTTPS encryption, firewalls, and retain anonymous log data for up to 90 days before deleting it permanently.

Your Rights

You have rights under global privacy laws. Depending on where you live, you can:

• See what info we have (usually anonymous usage data)
• Request the deletion of any stored data
• Turn off cookies in your browser settings
• Ask for a copy of your data (if you’re in the EU - GDPR)
• Say no to sharing info (though we share very little)
• Request parental review (if you're under 13 or a parent)

Privacy Laws We Follow

• GDPR (EU): Transparency, data control, right to access, correction, deletion, and portability
• CCPA (California): Disclosure, right to opt-out or request deletion, no sale of data
• COPPA (U.S. Children): Parental consent for any personal data collection
• PIPEDA (Canada): Openness, limited data collection, user access rights
• Other U.S. Laws: Like the Privacy Act of 1974, ensuring minimal and secure data collection

International Users: We extend GDPR-level protections to all users, regardless of location.
