Is BlockAds safe?
Yes. The app only filters DNS queries locally. No personal data is intercepted or transmitted.
Why does it need VPN permission?
For non-root devices, a local VPN tunnel intercepts DNS requests. If your device is rooted, you can use the Root Proxy Mode (iptables) instead.
Does it work with all apps?
Yes. BlockAds works system-wide. You can whitelist specific apps if needed.
Is it really free?
100% free, no ads in the app, no in-app purchases, and the source code is open.
