Will minification break variable names or scope?

No. Safe whitespace and comment stripping preserve variable identifiers and lexical scoping, ensuring execution integrity across production bundles.

Is my source code stored or sent to remote servers?

100% client-side. The parsing and compression algorithms execute in your browser’s volatile RAM with zero network telemetry or storage.
