Last updated 4 July 2026. In short: the calculators run in your browser, we don't collect your personal data, and our ad partner may use cookies.
Every calculator on Forge Numbers runs entirely on your device using client-side code. The numbers you enter — loan amounts, balances, rates, incomes and so on — are processed right there in your browser to produce a result. They are not sent to us, and we do not store, log or transmit the figures you type into any tool.
The site owner does not ask for or collect personal information such as your name, email address or financial details in order to use the calculators. There are no accounts to create and no sign-up. If you choose to email us (for example at contact@forgenumbers.com), we will of course see the email address and message you send, and we use that only to reply to you.
