Is Heyzine Flipbook to PDF Downloader safe?

Clean risk

This extension converts Heyzine flipbooks into downloadable PDF files.

Shared hosts - 4 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
