Is BlockSite safe?
BlockSite sends per-navigation browsing history and a persistent device identifier to its servers when the user enables analytics.
When analytics is opted in, the extension captures the current URL, previous URL, a timestamp, and a persistent GUID on every completed navigation, encodes the payload, and transmits it to adult.yourblocksite.com. The extension also stores the account lock password as reversible base64 in local storage, and when account protection is enabled it writes that password alongside all extension settings into a cookie that is transmitted to blocksite.co during the uninstall flow.
Part of this rating comes from analysis signals we haven't published as detailed findings yet.

What this publisher told the store about itself, and the other listings that told it the same thing.
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.

Where it sends data
Destinations our analysis observed BlockSite 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.
