Is Prompt Engine Pro safe?
Prompt Engine Pro stores its API token as a page-readable cookie on ChatGPT pages.
When you validate a token, the content script sends it to promptenginepro.com and then writes the returned token into document.cookie on chat.openai.com and chatgpt.com. That cookie is not HttpOnly, so scripts running on those ChatGPT pages can read the Prompt Engine Pro token while the extension uses it for categories, prompts, workspace, and history requests.

Where it sends data
