Is Gemini Storybook Exporter safe?

Exports Gemini Storybook content into PDF, text, and image files for sharing or archiving.

This extension turns Gemini Storybooks into polished exports such as PDFs, plain text files, and PNG/JPG image sets. PDF exports remove browser UI, can use a custom filename prefix, and support content in multiple languages. The description notes that most capture and export features work without sign-in, while cloud high-definition PDF rendering requires sign-in within the extension.
