## FAQ

### How does Shield protect my data?

It replaces client names and numbers with codes locally on your computer before the text is sent to the AI, and restores them only on your machine.

### Does Shield send my data to RAGbase?

No, Shield sends no usage statistics and nothing is sent to RAGbase.
