Calculator Data
The numbers you enter into our calculators — marks, grades, dates and similar values — are processed entirely in your browser to produce a result. They are not transmitted to or stored on our servers.
Contact Form
If you use the contact form, the name, email address and message you enter are sent directly via your own email client to our contact email address. We only use this information to respond to your message.
Cookies & Advertising
This site is designed to support advertising, such as Google AdSense, in the future. Advertising partners may use cookies or similar technologies to serve ads and measure their performance. You can control cookies through your browser settings, and can learn more about how Google uses data at Google's Partner Sites policy.
Analytics
We may use standard web analytics tools to understand overall site traffic and improve our calculators. These tools typically collect anonymized, aggregate usage data rather than personally identifiable information.
