The calculator runs entirely on your own device. Your balances, interest rates, payments, and the plan it builds for you are never transmitted to me, to Google, or to anyone else. Nothing is stored on a server, and closing the tab erases it. If you want to keep your plan, print it or save it as a PDF.
Google Analytics. I use it to see how many people visit and which parts of the calculator they actually use. It records the pages you view, roughly where in the world you are, what browser and device you are on, and how long you stay. It does not record anything you type into the calculator. Analytics sets a cookie to tell one visit from another. I have turned off Google's data sharing options and turned off site search tracking.
Google AdSense. The ads on this site come from Google. Third party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website 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/or other sites on the Internet. You may opt out of personalized advertising by visiting Ads Settings. You can also opt out of a third party vendor's use of cookies for personalized advertising at aboutads.info.
If you are in the European Economic Area, the United Kingdom, or Switzerland, you will see a consent message the first time you visit, and you can decline.
The feedback form. If you send me feedback, I get your message, and your email address if you chose to include one. It goes to my inbox and nowhere else. I do not add you to a list, and I do not share it.
