Terms of Service & Privacy Policy

Making math gooder since [Year]!

1. Terms of Service

Welcome to MathGooder.com (the "Website"). By using our calculator, you agree to these terms:

1.1 Use of the Calculator

  • This is a basic browser-based calculator for general arithmetic. It's not designed for complex computations, financial decisions, or academic testing.
  • You must be at least 13 years old to use this Website.
  • Please don't use our calculator for:
    • Launching rockets 🚀
    • Calculating lottery odds 🎰
    • Doing your taxes 💸

1.2 Disclaimer

The Website is provided "as is." While we try to make math gooder, we don't guarantee 100% calculation accuracy (especially if you divide by zero).

1.3 Intellectual Property

All content (including the calculator design and functionality) is owned by MathGooder.com. Unauthorized commercial use is prohibited.

1.4 Changes to Terms

We may update these Terms. Your continued use means you accept the changes.

2. Privacy Policy

We take your privacy as seriously as we take the order of operations (PEMDAS, baby!):

2.1 Data Collection

  • No Personal Data: We don't require accounts, emails, or your mother's maiden name.
  • Calculation Data: Your math inputs are processed locally in your browser and never sent to our servers.
  • Analytics: We use basic tools (like Google Analytics) to see which buttons people press most (hint: it's probably "=").

2.2 How We Use Data

  • To improve the calculator's functionality (e.g., adding a % button if enough people miss it).
  • To count how many times someone tries to divide by zero (just kidding... maybe).
  • We do not sell or share your data - that would make us math badder.

2.3 Cookies

We use minimal cookies (not the chocolate chip kind) to:

  • Remember if you prefer light/dark mode
  • Track basic site usage (anonymously)

2.4 Third-Party Services

We might use:

  • Google Analytics: To see if people actually use the memory functions
  • Hosting Services: Like Carrd or Netlify to keep the calculator running

2.5 Children's Privacy

This Website complies with COPPA. We don't knowingly collect data from children under 13 (but we do encourage them to practice their times tables!).
