Answers to the most common questions on using FiMo's mathematical tools.
1. Is FiMo completely free?
Yes. FiMo was built with the goal of serving the community, so all 30+ financial calculation tools on the platform are provided completely free for life. We do not display ads, do not sell premium plans, and do not use affiliate links. You can use all tools in a simple, transparent, and distraction-free way.
2. Is my financial data saved on your servers?
All calculations are performed on your device. We do not store any of your information on our servers unless you intentionally use our Save feature for easier access later.
3. How accurate are the calculations?
We integrate arbitrary-precision libraries like decimal.js and institutional methods like Monte Carlo simulations. However, all outputs are purely theoretical mathematical projections, not explicit financial advice.
