Why so little?
Because the model costs almost nothing to run. It is a static page that does its arithmetic in your browser, so a visitor costs bytes and nothing else.
What happens to my e-mail address?
It signs you in and it tells you when the model has new figures in it. Nothing else, and never to anyone else.
Can I cancel?
There is nothing to cancel yet. When there is, it will be one button and it takes effect at the end of the month you paid for.
Is this investment advice?
No. It is a spreadsheet with a nice front end. Every number in it is an assumption, including the ones I chose.
