# personalDNSfilter (open-source privacy app)

> personalDNSfilter is a free, open-source privacy app for Android. DNS request based Host Blocker over local VPN using a Blocklist. It has 948 GitHub stars and is released under the GPL-2.0-only license, and you can install it from F-Droid.

personalDNSfilter is a DNS filter proxy written in Java. It hooks into the domain name (DNS) resolution and returns the loopback address for filtered hosts. It can be used for filtering ads and other unwished hosts based on a host list – thus it is a good AdBlock alternative. On Android 4.2 and newer it can be used as effective ad, malware and tracking server filter without root access! It works with any upstream DNS server - filtering is completely local - no phoning home or such things! You can run it locally on your device or centrally as DNS server in your network.
