Is Who Deleted Me - Unfriend Finder safe?

Medium risk

Who Deleted Me can send full Facebook page responses to api.deleted.io when detailed error logging is enabled.

During sync, it fetches Facebook profile, settings, and friends pages and stores each requested URL, loaded URL, status, and full response body in its error-log buffer. If an error-log response from api.deleted.io includes an id and logDetails=true, it posts those buffered records to logs/error/details, which can include Facebook HTML content and URLs.

Shared hosts - 2 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.
