Hey, thanks a lot for the feedback! It's not harsh, direct feedback is by far the most useful. You are right, it is not super clear how the simulation is done, I'll add that to the page. Currently, you enter a volatility rate, and then the simulation randomly draws from a normal distribution according to the volatility. Doing this around 1000 times gives the range of possible scenarios. In the future I'm planning to add simulations based on historical data. The code is not open source, however you also don't have to connect any banking to it, it can be used as-is. I am taking privacy pretty seriously, that is why there is a legally binding privacy policy on the bottom of the page. But yes, I could put more emphasis on it, and explain how the page is keeping data secure.
