Is Link Shortener safe?

Clean risk

Link Shortener sends the active tab URL to T.LY's shortening API when its popup opens.

When auto-shorten on click is enabled by default, opening the toolbar popup reads the current tab's URL and posts it as long_url to api.t.ly with provider settings and the extension version. If the user configures Rebrandly instead, the same shortening flow can send the destination URL to api.rebrandly.com. The code path is triggered by the extension popup, not by arbitrary webpages.

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.
