What data it declares

The developer declares that it collects these kinds of data:

• Personally identifiable information such as name, address, email address or age
• Personal communications such as emails, texts or chat messages
• Website content such as text, images or links on the pages you open

The developer also certifies that your data is not sold to third parties outside approved uses, not used for purposes unrelated to the extension's core function, and not used to decide creditworthiness or lending.

The listing links to a privacy policy.

This is the developer's own declaration in the Chrome Web Store. We cannot check it against what the extension does.

What Chrome asks you to allow

When you add it, Chrome asks you to allow it to:

• Read and change your data on a number of websites

Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.

What it can reach

Specific sites only: 9 match patterns.

• https://chatgpt.com/* only chatgpt.com
• https://chat.openai.com/* only chat.openai.com
• https://claude.ai/* only claude.ai
• https://gemini.google.com/* only gemini.google.com
• https://grok.com/* only grok.com
• https://chat.deepseek.com/* only chat.deepseek.com
• https://copilot.cloud.microsoft/* only copilot.cloud.microsoft
• https://m365.cloud.microsoft/* only m365.cloud.microsoft
• https://docs.google.com/spreadsheets/* only docs.google.com

Worth knowing

• Run its own code on the pages it can access scripting

Routine for an extension

• Run work in a hidden page offscreen
• Open a panel beside the page sidePanel
• Store data in your browser storage

Pages it runs its code on

It runs its own code on specific pages only: 10 site patterns.

• https://chatgpt.com/* only chatgpt.com
• https://chat.openai.com/* only chat.openai.com
• https://copilot.cloud.microsoft/* only copilot.cloud.microsoft

A content script is code the extension injects into pages matching these patterns. On those pages it can read and change what you see, whether or not a host permission is listed above.

What it may ask for later

Not granted when you add it: Chrome asks you the moment the extension requests one of these, and you can refuse.

• http://127.0.0.1/* only 127.0.0.1
• http://localhost/* only localhost
• http://[::1]/* only [:

Has it asked for more over time?
