Net Data Protector: Ad Blocker

🛡️ Net Data Protector — Your Personal App Firewall & Ad Blocker


Ever had an app show you an unexpected ad—even when you weren't using it?


Some Android apps continue connecting to the Internet in the background to load ads, sync data, send analytics, and communicate with tracking services. This can consume mobile data and create unwanted background activity.


Net Data Protector gives you control over those connections.


Block Internet access for any app using Mobile Data, Wi-Fi, or both. By cutting off an app's network access, you can prevent it from fetching new online ads and sending unwanted network traffic.
