What we do
Apexa Pro is a small collection of focused calculators — percentages, dates, loans, health, construction and more — built to answer one specific question quickly, without clutter, sign-ups, or downloads.
Privacy by design
Every calculation runs directly in your browser using JavaScript. The numbers you type — a loan amount, a date of birth, a body weight — are never sent to our servers or stored anywhere. We have no database of user inputs, because we never built one. See our Privacy Policy for the full details on analytics and advertising.
Who it's for
Students checking homework, professionals running quick project numbers, and anyone who wants a trustworthy answer without an app install or an account. Every tool is designed to work well on a phone, since that's how most people search for a quick calculation.
How the site stays free
Apexa Pro is supported by advertising. We don't charge for any calculator, and we don't plan to.
