Is my text sent to a server?

No. All processing runs in your browser. Your text never leaves your device.

Can I use capture groups in regex mode?

Yes. Use standard JavaScript regex syntax — e.g. find: (\w+), replace: [$1] to wrap each word in brackets.

Why is Whole Word greyed out in regex mode?

In regex mode you control the full pattern, so you can add \b word boundaries yourself. Whole Word only applies in plain-text mode.
