This Badger Calculator is a Western Lands Preservation branded version of our 15-feature easy-to-use basic calculator that's on our home page.  The difference is this has no ads, no frame, and makes no network calls, even for images.  So it's fast, does not spy on you, and does just what you request.  Can be used locally on a secure device.  You also get to personalize it with your name or short phrase.

10% of your calculator purchase goes to Western Lands Preservation to assist their efforts in preserving Western Lands in their natural state for present and future generations.

This Badger Calculator remembers its calculations when closed, so when opened again, the calculator is just where the user left off, even if that was in the middle of a calculation.  Nice :-)

Calculator is delivered as a single HTML file (~70KB), and can be used on any device that has a browser, such as touchscreen devices, desktop PCs, laptops, iPads, smartphones, etc.  Perfect for use in meetings, classes, presentations, at home, and it is designed for frequent all-day use.
