Overview

CalcEngine respects your privacy. All calculations run entirely in your browser — the values you enter into any calculator are never transmitted to, stored on, or processed by our servers.

Information We Do Not Collect

We do not require accounts, logins, or personal information to use any calculator. We do not collect, store, or sell the numbers, dimensions, or financial figures you input. Your inputs stay on your device.

Analytics & Cookies

We use Google Analytics to understand aggregate, anonymized usage — such as which calculators are most popular and general traffic levels. This data does not identify individual users. If advertising is shown, third-party ad providers may use cookies in accordance with their own privacy policies. See our Ad Choices page for details and opt-out options.
