Are Maestrodia's finance tools really free?
Yes, all the tools in the Finance category (compound interest, currency converter, discount calculator) are free, require no sign-up, and have no usage limit.
Is my financial data sent to a server?
No. Calculations run directly in your browser; no data you enter (amounts, rates, duration) is transmitted or stored on our servers.
What's the difference between the compound interest calculator and the currency converter?
The compound interest calculator simulates how savings grow over time (contributions, rate, duration), while the currency converter gives an instant exchange rate between two currencies.
Can I use these tools to make an investment decision?
These tools give useful estimates for comparing scenarios, but they are not personalized investment advice; for a decision with real stakes, consult a professional.
