TSOSX Shield
VPN, DNS shield and device security checks in one Android app.
Overview
What it is
TSOSX Shield protects traffic on Android: a sing-box VPN tunnel, a DNS shield that blocks ad and tracker domains on the device, and checks of installed apps, APK files and phone security settings.
Problem
Why it exists
A VPN alone does not tell you what your phone is leaking: which trackers your apps talk to, whether a downloaded APK is known-malicious, or which security settings are switched off. And most privacy apps ask you to trust a logbook you cannot see.
Solution
How it works
Shield combines the tunnel, the DNS filter and the scanner in one app, and keeps the sensitive parts on the device: the DNS log lives in memory, the installed-app list never leaves the phone, and an APK is checked by its SHA-256 fingerprint rather than by uploading the file.
