In-depth safety analysis
This extension asks only for the "storage" permission, which lets it save a small amount of data locally in your browser, such as settings or preferences. It cannot read or modify the websites you visit. For a general browser extension, this is a very limited and safe permission scope that does not expose your browsing activity.
General browser extensions can vary widely in purpose, and even simple utilities can become targets for developers who change an extension's behavior later through automatic updates. A careful user should understand that maintaining good ratings and a clean permission set now does not guarantee the extension will remain safe forever, especially if ownership changes or the developer abandons it.
Looking at the fact sheet, the strongest dimension is Data & Privacy, reflecting the developer's declared privacy practices and minimal required permissions. The weakest dimension is Maintenance & Ownership, which suggests some uncertainty about how actively the extension is managed or who exactly is behind it despite the recent update date.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.

Who's Behind Flow3?
- Publisher Flow 3
Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
