Question 1

Are LF Tools free to use?

Accepted Answer

Yes. The published utilities are free to use and do not require an account.

Question 2

Do local tools send my content to a server?

Accepted Answer

No. Browser-based tools such as JSON formatting, password generation, text analysis, encoding, QR generation and unit conversion process the entered content locally.

Question 3

What happens when a tool uses live data?

Accepted Answer

For live results, the required lookup input is sent directly from the browser to the named provider. The tool shows a notice before the request is made.

Question 4

Why can live results occasionally fail?

Accepted Answer

Live results rely on independent data providers and the visitor's connection. The interface uses timeouts and clear errors instead of retrying indefinitely.
