Is JSONView safe?

Low risk

JSONView temporarily routes Chrome update checks through agency.pictureknow.com when its version probe fails.

JSONView checks api.pictureknow.com for version information and probes Chrome's update host. If the probe fails after it sees a newer version, it installs a PAC proxy for about one minute that sends Chrome update requests through agency.pictureknow.com, then requests an update check and clears the proxy.

Where it sends data

Destinations our analysis observed JSONView 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.
