What does Stopwatch do?

Stopwatch provides the function described in the intro directly in your browser — no installer.

Is data sent to a server?

No. Stopwatch processes the standard mode locally in your browser; Tentaco does not receive your input for that path.

Do I need an account?

No. Open Stopwatch and start immediately.

Does this replace professional advice?

No. Stopwatch is a technical helper and does not replace legal, tax or professional advice.
