Is X-notifier Neo safe?

Clean risk

X-notifier Neo reads unread email metadata from multiple webmail providers to show mail notifications.

The extension fetches webmail provider endpoints using the browser's signed-in cookies, then parses unread counts and message details such as sender names, sender email addresses, subjects, snippets, message IDs, timestamps, folder counts, and account identifiers. It stores the parsed mail data in local extension storage and uses it to display notifications.

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.
