Privacy checklist for AI browser extensions

Permissions

AI assistants that read pages need access to websites. Check the permission list and whether the extension explains why it needs each one.

What is sent and when

Good extensions send page content only with your request, not in the background. Claude Duet sends a page only when you ask about it or when the agent works on it.

What is stored

Ask: where are my chats? Claude Duet stores chats, memory, calendar and automations in your browser; our server keeps only an install ID, counters and subscription records.

Who processes it

Check which AI providers receive your requests and whether the developer uses analytics or ads. We use no analytics or ad trackers.

Remote code

Extensions shouldn’t download and run code from the internet. Claude Duet runs no remote code.

Deleting your data

Look for a clear way to delete everything. In Claude Duet: Settings → Privacy → “Delete all my data”.
