Is Free Android online emulator ApkOnline safe?

Medium risk

Free Android online emulator ApkOnline sends non-ApkOnline tab URLs with a persistent user ID to www.uptoplay.net.

When a tab activates or updates, the background script reads HTTP(S) tab URLs that are not Uptoplay or ApkOnline pages and sends an encoded URL, tab ID, and stored user identifier to www.uptoplay.net. If the server response contains 302, the same code can redirect the tab through an Uptoplay intro URL carrying the original URL and identifier.

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.
