Frequently Asked Questions

Our Story

CoreCulator was created in 2024 by a team of developers frustrated with calculator websites that required accounts, collected personal data, or buried simple tools under layers of advertisements.

We believe that useful tools should be:

• Accessible: Available to everyone, regardless of device or location
• Private: Your financial and health data is yours alone
• Reliable: Accurate calculations you can trust
• Fast: Instant results without loading screens

Today, CoreCulator serves thousands of users daily across the globe, from students checking their GPA to families calculating mortgage payments.

1. Information We Don't Collect

CoreCulator is designed with privacy as the default. We do NOT collect:

• Personal identification information (name, email, address, phone)
• Financial data entered into calculators
• Health information or biometric data
• IP addresses or location data
• Browser type or device information
• Usage patterns or calculator inputs
• Cookies or local storage data

2. How Our Calculators Work

All CoreCulator calculators operate using client-side JavaScript. This means:

• When you enter numbers into a calculator, the processing happens on your device
• No data is sent to our servers (we don't even have servers for calculations)
• Your inputs exist only in your browser's temporary memory
• When you close the page, all data is automatically erased
• We cannot see, access, or retrieve anything you calculate

This architecture ensures complete privacy - even if our website were compromised, there would be no user data to steal because we never have it.

3. Third-Party Services

CoreCulator does not use:

• Google Analytics or similar tracking tools
• Social media sharing buttons that track you
• Advertising networks that profile users
• CDN services that could log your IP
• Font services that could track usage

The only external connection made is when you initially load the page from our web host. After that, everything works offline.

4. Contact Form Data

If you choose to use our contact form (on the Contact page):

• Your message is stored temporarily in your browser

5. Children's Privacy

CoreCulator is safe for users of all ages. Since we don't collect any personal information, children can safely use our educational calculators (GPA, math, science) without parental consent requirements under COPPA.

If we ever change this privacy policy (for example, if we add user accounts in the future), we will:

• Update the "Last updated" date at the top of this page
• Post a prominent notice on our homepage
• Never retroactively apply new data collection to past users

However, our commitment to privacy is fundamental to CoreCulator's mission. We have no plans to ever collect user data.
