In-depth safety analysis
This extension requests only two permissions: downloads (to save subtitle files to your device) and storage (to keep local settings). It does not ask for access to any website content, which is notably restrained for a tool that works with YouTube. For a subtitle download helper, this permission scope is minimal and well-aligned with its stated purpose.
General-purpose browser extensions that interact with media platforms can sometimes request broad host permissions, but this one avoids that. A careful user should still be aware that any extension capable of downloading files could be repurposed through an update to fetch content from other sources, though Manifest V3 limits some background behaviors. The developer’s privacy declarations state that data is not sold or used for unrelated purposes, which is a positive signal, but these are self-reported and not independently verified.
The strongest dimension in the safety assessment is Permissions & Access (90%), reflecting the extension’s limited and appropriate API use. The weakest is Publisher & Identity (60%), which indicates the developer is an individual with little publicly established reputation. This is common for niche utilities
