Is LYH DOI Tools safe?

Clean risk

LYH DOI Tools stores URLs and discovered DOI strings from visited web pages in Chrome sync storage.

It runs content scripts on HTTP and HTTPS pages, scans page text and links for DOI-like identifiers, and records matches. When it finds DOIs, it stores the current page URL as the key and the DOI list as the value in chrome.storage.sync for reuse by the extension.

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.
