Is Turn Off the Lights safe?

Low risk

Turn Off the Lights accepts color theme commands from any website via an unvalidated custom URL scheme handler.

The extension's content script runs on all pages and listens for clicks on links using the turnoffthelights:// scheme. When a nighttheme action is triggered, it decodes a JSON payload from the link and writes color values directly to chrome.storage.sync — without checking which site caused the click. Any page can craft such a link to overwrite the user's saved night-mode color settings.

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.
