EDS NG is capable of functioning without network access. You can block its network access using the firewall app. Network access is only necessary in the following cases:
1. Accessing cloud storage or local network storage.
2. Streaming encrypted media files to the external mediaplayer application, which you can disable in the settings.
3. Making in-app purchases, which can be done by sending an email request.
4. Activating automatic features, which can be manually activated by sending an email request or using a web browser.
