Privacy: your numbers never leave your browser

RepayCompass was built so that using it requires trusting math, not trusting us with your data. Everything you type into the calculator is processed on your own device and vanishes when you close the tab.

Updated August 18, 2026

What happens to the numbers you type?

Nothing leaves your device. The calculator is JavaScript running in your browser: your loan balance, income, family details, and every result computed from them exist only in your browser's memory while the page is open. There is no server-side calculation and no database — the calculator sends none of it anywhere, and the pages themselves are static files. Close the tab and your inputs are gone.

What we don't have

Email — only if you ask for it

There's a form for rules-change notifications. If you use it we store your address and nothing else — not your income, not your balances, not your results, which never leave your browser in the first place. The form sends one field to us and cannot reach the calculator. We use the address to email you when the repayment rules change. Every rules-change email carries an unsubscribe link, and a reply saying “unsubscribe” works on any email we send. We don't sell or share it.

What IS stored on your device

One thing: your light/dark theme choice, kept in your browser's local storage so the site doesn't flash the wrong theme next visit. It contains the word dark or light and nothing else. Your financial inputs are never written to local storage or anywhere else.

What the web server sees

Like every website, the server that delivers these files sees a standard page request — your IP address and which page was fetched — and our hosting provider may keep routine server logs. What makes RepayCompass different is that your financial data is never part of any request: the page you download is identical for everyone, and your numbers stay on your side of the wire.

Links to other sites

We link heavily to official sources — StudentAid.gov, the Federal Register, the CFPB — and those sites have their own privacy practices. Links marked with their destination open in a new tab; nothing about your calculator inputs is passed along.

If you email us

The feedback address is ordinary email: we'll see whatever you choose to send and use it only to follow up. Please never include Social Security numbers, account numbers, or login credentials.

Who we are (and aren't)

RepayCompass is an independent educational tool. It is not affiliated with, endorsed by, or operated by the U.S. Department of Education or any loan servicer. For decisions about your loans, your servicer and StudentAid.gov are the final word.

Why this is possible: the whole product is client-side math — see how the math works — so there was never a reason to collect anything. Try it on the calculator.
