Is Unofficial reMarkable safe?

Clean risk

Unofficial reMarkable converts the selected page and uploads the document to reMarkable cloud storage when you click it.

When you use the extension popup on the active tab, it injects a converter, captures the page document or current PDF/image, and sends the converted file to reMarkable cloud storage. The upload includes the document content, page title as the file name, and the stored reMarkable account token needed for the request.
