Is one sec | Website Blocker, Screen Time, Digital Detox, ADHD, Block Websites safe?

Low risk

one sec intercepts tab navigation to configured websites and displays a friction screen before the user can continue.

When a user attempts to open a website they have added to their block list, the extension detects the navigation in the background service worker and sends a message to the content script to display an interstitial (a breathing exercise or delay prompt). Block schedules and session data are stored locally in chrome.storage. For users who create an account, the extension can communicate with web.one-sec.app/api/v1 to sync settings and subscription status across devices.

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.

Where it sends data

Destinations our analysis observed one sec contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
