Is Privacy Guardrail safe?

Medium risk

Privacy Guardrail can send stored original text back to supported AI chat pages through its clipboard restore flow.

On ChatGPT, Claude, and Gemini pages, the extension intercepts clipboard writes and keeps mappings between placeholders and original values. If a page triggers the restore flow and the user clicks the toast, the content script posts the de-anonymized text back to the page, where scripts on that AI site can read it.
