You don't have to do anything when you first install the blockerDNS extension. It's running automatically. To temporarily turn it off, just click the red stop sign icon in your extensions and click the switch.
Do you collect any of my data?
No. The only information we have is that which is provided to us by the Google Chrome or Microsoft Edge store (i.e., number of extension installs/uninstalls, etc.). We collect absolutely no information while the extension is being used. All of the filtering/ad bocking is done locally. In other words, the extension does not "phone home" with your data or send any requests back to us. We don't even collect the kind of legitimate information lots of other developers do that lets them see how you use their product so they can figure out where things need improving.
That said, the extension does occasionally talk to the blockerDNS servers for one sole purpose, though, and that is to check if there is an updated version of the ad and tracker block list. When you first install the extension it comes with a built-in list, and we originally planned on putting out a new version of the extension through the Chrome and Edge web stores with a fresh built-in list each time we updated it. But both the Chrome and Edge store review processes for new extension versions take a few days. And since we prefer users to have the latest block lists as soon as possible, we added the ability for the extension to check for updated lists. The request it makes to our server does not include any user information whatsoever. No authentication, no id number, nothing.
What about blocking ads and online trackers on my phone or other devices?
Yes! We have ad and tracker blocking through encrypted DNS over TLS (best way for Android phones - no app needed!), DNS over HTTPS (great for older Android phones running Android 8 or older, also great for Firefox on any device with their built-in support) and standard DNS (virtually any device - desktop computers, WiFi routers, anything).
