Is Steam tags for Humble Bundle safe?

Clean risk

Steam tags for Humble Bundle sends Steam library, wishlist, ignored, and recommended app IDs to its developer API.

When you use it on Humble Bundle pages, the extension reads Steam's dynamic store data for your owned, wishlisted, ignored, and recommended apps. It posts those app IDs, and any configured Steam profile library data, to humble-steam-sync.haaxor1689.dev so the page can match Humble Bundle items to Steam tags.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 1 hostname

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.
