Privacy Policy
Last updated: October 18, 2026
What we collect
We do not ask for your name, phone number, email address, or any account information, and we do not collect, store, or sell anything you enter into the tools. The calculations run in your web browser. If you save a results page as a PDF or text file, it is created on your device.
Visit counts
We use Cloudflare Web Analytics to count visits and see which pages are used. It collects general information such as the page you visit, the site that sent you here, your type of browser, device, and operating system, your country, and how quickly the page loaded. It does not use cookies, and it does not collect what you enter into the tools.
Rate data
The rate estimator shows current market averages. To get them, your browser asks a small rate service that we run, and it does not receive what you enter. The averages come from Freddie Mac and the Federal Reserve through the St. Louis Fed’s FRED service, and the 10-year Treasury yield also comes from the U.S. Department of the Treasury.
Advertising
This site is supported by ads from Google AdSense, and may also show ads from other third-party advertising networks. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site or other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and other sites on the internet. These companies may also use web beacons and collect information such as your IP address, device and browser type, and the pages you visit. We do not control what they collect or how they use it.
You can opt out of personalized advertising by visiting Google’s Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalized advertising at www.aboutads.info. To learn more about how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services. Depending on where you live, you may also be able to limit personalized ads through your browser or device settings.
Information only
This site is for general information only. It is not a lender, does not make loan offers or give rate quotes, and nothing on it is financial advice. Ads are not endorsements of any company, product, or service.

This site is not directed to children under 13, and we do not knowingly collect information from them.
