# Frequently Asked Questions

How BQ Calculator handles calculations, privacy, accuracy and browser features.

## Frequently asked questions

### Are BQ Calculator tools free to use?

Yes. The calculators in this release are available without an account or subscription.

### Do my calculator inputs leave the browser?

The calculator engines run in your browser and do not use an external calculation API. Optional recent history is stored locally in browser storage.

### Does BQ Calculator use third-party JavaScript?

No. The runtime is built with first-party HTML, CSS and vanilla JavaScript, with native Canvas used where a visualization is useful.

### Can I use a result as professional advice?

The calculators are informational tools. Finance and health results in particular include limitations and should not replace qualified professional advice when a decision requires it.

### Can I print or copy a calculation?

Yes. Every launch calculator includes copy and print controls, and print styles focus on the calculator assumptions and results.

### Need a tool?
