In-depth safety analysis
This extension requests permission to read and change data on all websites you visit, plus storage and context menu access. That host permission is unusually broad for an e-book reader, which typically only needs to open local files or fetch books from specific sources. The storage permission allows saving settings or book data locally, and context menus let it add right-click options.
For any e-book or EPUB reader, a careful user should know that broad host access means the extension could technically see sensitive information like login details or banking pages, even if it only intends to display book files. Always review what an extension can access, and consider whether a simpler reader that doesn’t require all-website access might meet your needs.
In our assessment, the extension’s strongest dimension is Maintenance & Ownership, indicating it is actively maintained and the codebase is likely up to date. The weakest is Publisher & Identity, meaning there is limited public information about the developer, which can make it harder to evaluate long-term trustworthiness.
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 Sevina
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.
