In-depth safety analysis
This extension requests only the "storage" permission, which lets it save data like reading position or user preferences locally inside your browser. That is a minimal, expected scope for an EPUB reader—it does not need access to your browsing history or open tabs. The developer’s declared privacy practices (data not sold, not used for unrelated purposes, not for creditworthiness) further match this limited data access.
E-book readers that open EPUB files can render HTML and JavaScript content, so any vulnerability in the underlying engine might expose you to risks if you open untrusted files. Generally, users should only open EPUBs from reliable sources and keep their browser up to date. Additionally, extensions in this category are sometimes cloned with malicious intent; verifying the publisher and checking user reviews helps avoid lookalikes.
In the fact sheet, the strongest dimension is Data & Privacy, scoring 100% and indicating transparent, minimal data handling claims. The weakest dimension is Maintenance & Ownership, at just 10%. This reflects a last update in October 2023 and a generic publisher domain, which can signal a lack of ongoing upkeep and potential security patching gaps over time.
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 ePub Reader?
- Publisher https://epub-reader.freeonlineapps.net/
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.
