Is Netflix Dual Subtitles - Subtitle Translator Safe? — Extension Safety Profile

This extension requests only the “storage” permission and host access to its own domain (*.netflix-dual-subtitles.com). That means it can save settings locally and fetch data from its own server, but it cannot read or modify any content on Netflix.com. For a subtitle tool that normally needs to overlay text on a streaming page, this is a notably limited permission set, which reduces the risk of the extension accessing your Netflix activity directly.

Subtitle and translation extensions for streaming sites often ask for broad host permissions to inject captions, which could potentially capture what you watch or interact with. While this extension avoids that by not requesting Netflix access, users should still be aware that the developer declares it collects personally identifiable information and communicates with its own server. As with any extension that handles personal data, it is wise to review the privacy policy and ensure you are comfortable with the data handling practices.

The strongest dimension in the safety assessment is Maintenance & Ownership, indicating the extension is actively updated and its ownership is clear, which supports ongoing security. The weakest is Publisher & Identity, suggesting the developer’s background may be less transparent. A careful user should verify that they are installing the official extension and not a look‑alike, as popular streaming tools are sometimes imitated by malicious clones.
