## FAQ

### Who is this collection for?

It is for students, freelancers, households, and anyone who wants a quick browser-based tool to make a small planning or money decision.

### Why group these tools together?

They often appear in the same real-world flow: estimate the number, draft the output, then move to the next planning step without losing context.

### Do these tools save my numbers?

No. Each tool calculates locally in your browser and keeps nothing after you close the tab. Your salary, invoice details, grades, and net-worth figures are never uploaded or stored on a server.

### Are the results precise enough to rely on?

They are good for quick, informed decisions, and most tools show the assumptions behind the figure so you can adjust them. For tax filing, formal financial planning, or construction, treat the output as a starting estimate and confirm with the appropriate professional tool.
