The extension

The extension bundles no third-party code. Everything that runs in your browser, including the video muxer that writes the MP4 files, the device frame geometry and the accessibility audits, was written for Viewport and ships as plain JavaScript with no build step and no dependencies.

This is why the extension package is small and why it can be read end to end. It also means there is no third-party code in it that could be doing something this policy does not describe.

Icons and artwork

The icon set is drawn for Viewport on a 24 pixel grid in the style established by Feather, which is itself MIT licensed. The device frames are drawn from measurements rather than traced from images, so no manufacturer artwork is redistributed.
