Netspark is a filtering app that provides comprehensive content filtering for smartphones and tablets. The app offers complete content filtering, even without an internet connection, and can filter locally stored or external content. The app features Always-On Protection (AOP), real-time sexting deterrence, partial clothing filtering, and automatic blocking of inappropriate content. Additionally, the app cannot be removed without a parent's permission. Other features include pre-defined filters by category, parental alerts, screen time limits, custom exceptions for approved apps and websites, and the ability to manage multiple accounts from the parent's device or remotely online. The app is available in both English and Hebrew.

The app uses various permissions to help users with behavioral disabilities set appropriate levels of access and monitoring of screen time, web content, and apps. The monitoring is private, and no third parties will be aware of it. The app also uses the Draw Over Other Apps permission to draw a block screen on top of apps that the user chooses to block. The Usage Access permission is used to detect which application is opened so that the app can have a suitable filtration in it. The app uses the Device Administrator permission to allow parents to enable uninstall protection and prevent their children from uninstalling the app without their knowledge and consent. The app also uses VPN service to securely pass relevant content through the filters in remote servers to determine whether or not the content is inappropriate and should be blocked.

The app's term of use and privacy policy are available on the Netspark website. For help and more information about the app's permissions, users can visit the Netspark website.
