Is Quiet Reader — Reader Mode Safe? — Extension Safety Profile

By requesting activeTab, scripting, and host permission for <all_urls>, this extension can read and modify any web page you are on once you activate it, and it can store your preferences locally with storage. That scope is fairly standard for a reader mode tool, as it needs to extract and restyle article text from any website. The use of Manifest V3 keeps the extension aligned with current browser security practices.

Reader mode extensions generally pose a moderate privacy consideration: they have the ability to see all visible text on every page where you use them. While many use that access solely for reformatting, a user should be comfortable that the publisher will not collect or inject additional content. In this case, the developer has self-declared that data is not sold or used for unrelated purposes, which provides some transparency under Chrome’s privacy disclosures.

The fact sheet points to two contrasting risk signals. A perfect Maintenance & Ownership score (100%) means the extension is actively maintained and recently updated, reducing the chance of drifting into an insecure or broken state. On the other hand, the lowest dimension is Publisher & Identity (60%), indicating limited public verification of who stands behind “Chrome Reader Mode.” If you are cautious about granting broad page-reading access, it is sensible to check whether the publisher has a clear website or support channel before installing.
