Are you planning to add a self-hosted option? My one thing about all these finance SaaS is that I'm sure part of their business model is selling your data, even if anonymised. I'd be happy to pay a one-off fee and self-host it or something.
Selling data is not part of mine. In fact, once the page loads you should be able to turn off your internet connection and have all the planning/simulation features still work. Everything stays client-side by default, the only way plan data is ever transmitted anywhere is if you upgrade to Premium and then choose to enable cloud synchronization (which is one of 3 different data persistence methods).
