2025-09-15 00:00:00 Ad And Stuff DNS Filter uses the VPN on the device to filter URLs, much like a hosts file. It supports optionally blocking ads and porn. It works by routing DNS calls only through the VPN. The VPN replies with Unknown if the requested host is in the app's internal database. Otherwise, it passes the request to the DNS provider selected for the VPN, which defaults to OpenDNS and can be changed. The only external calls explicitly made by the app are to the DNS provider - the app does not call home or anywhere else and does not collect any data, personal or otherwise. The app is not ad supported and does not feed you ads. Any ads, or porn, received are from whoever your web browser or other app is calling since that traffic does not go through the VPN. If you are filtering ads and/or porn, and you see ads and/or porn, then please let us know. Some ads are not be possible to block with this app. For instance, you will still get ads in YouTube videos because those ads come from youtube.com. So the only way to block those ads is to block youtube.com and get nothing from there.
