Is one sec | Website Blocker, Focus, Screen Time safe?

Low risk

one sec exposes its encoded extension runtime ID to every visited page.

The extension runs a content script on all websites at document start. That script adds a page-readable attribute containing the base64-encoded browser extension runtime ID to the document element.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 5 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.
