Questions
Do I need to install anything?
No. Each tool is a single file. Double-click it and it opens in Chrome, Edge, Safari or Firefox — whichever you already have. No account, no password, no software.
Does anything get uploaded?
No. Your numbers and files never leave your computer — the tools have no way to send them and no internet connection is needed to run them. You can switch your wi-fi off and they still work.
I'm not good with computers. Is this too hard?
The first thing every tool does is walk you through it in five short screens with pictures. Then there's a button that fills it with example numbers so you can watch it work before touching anything.
Will it work on my phone?
Yes. Email yourself the file and open the attachment, or drop the files in iCloud Drive, Dropbox or Google Drive and open them from there — then they're on every device you own.
