In-depth safety analysis

This extension requests only storage API permission and host access to Prime Video and Amazon domains. That means it can save settings, and on those sites it can read or modify page content, which is typically needed to adjust video playback speed. For this category, limited host access to the relevant streaming domains is generally expected, though access to multiple Amazon country domains is somewhat broader.

The developer-declared privacy practices include collection of personally identifiable information, authentication information, location, user activity, and website content. These declarations are not independently verified, but they are broad for a playback utility. General guidance for this category applies: extensions with host access to streaming pages can see visible page content while active, so a careful user should review the privacy policy and prefer clearly maintained extensions.

The strongest dimension is Permissions & Access, indicating a relatively small permission footprint. The weakest is Publisher & Identity, showing more limited evidence about the developer's public track record or identity.

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.
