Questions
My company blocks downloaded programs. Will this work?
It is not a program. It is a web page saved as a file, and it runs inside your browser with the same limits as any web page. If your company blocks HTML files as well, use the tools on this site instead; they are the same.
Which browsers?
We tested it in Chrome and in Edge. It uses standard browser features, so current versions of Firefox and Safari should work; we have not tested them.
Does it count how often I use it?
No. The file cannot send anything. This page counts how many times the download button is pressed, and nothing else.
What does it cost?
Nothing. Simon G., the platform that runs the same calculations every night with approvals and a record of decisions, is a paid product.
