Is Wappalyzer safe?
Wappalyzer collects visited hostnames and detected technologies and transmits them in batches to its own servers.
On each page visit, Wappalyzer reads response headers, cookies, and page scripts to identify the technology stack in use. Batches of up to 25 hostnames — each carrying detected technology names, versions, and hit counts — are periodically POSTed to ping.wappalyzer.com. On Chrome, this telemetry is sent without explicit user consent; Firefox users are shown a terms acceptance page before data is transmitted.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 2 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.

What it can do
Permissions this extension asks for, as declared in version 6.12.8. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.

Where it sends data
Destinations our analysis observed Wappalyzer 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.
