Yes, completely. The difference logic runs entirely inside your browser's local sandbox using JavaScript. No text is sent to our servers or stored databases, ensuring full confidentiality.

When enabled, the tool ignores tabs, spaces, or indentation alterations. It focuses solely on text and semantic content modifications, which is helpful to ignore formatting changes in source code.
