Your loan data stays in this browser

We do not receive, store, log, or analyze the loan numbers you enter. The calculation page has no account system and no financial-data API.

Your inputs live temporarily in browser memory and disappear when you close or reload the page.

Cloudflare hosts and protects this site. When you visit, Cloudflare may process standard access information such as your IP address, requested URL, browser user agent, timestamps, and security or performance data to deliver and secure the site. Cloudflare may retain this information according to its policies and our service configuration. These records do not include your loan inputs or calculation results because those values are not sent in web requests.

The calculation page blocks connections to third-party origins with a Content Security Policy. You can verify the lack of calculation requests in your browser's Network panel.

An important limit: code you run yourself in DevTools, a malicious browser extension, a compromised browser, or malware on your device can read what is shown in your browser. No website can fully protect against those conditions.
