Description
Droynis checks the security and privacy settings of the phone it runs on, explains every finding in plain words, shows the raw evidence and opens the Settings screen that fixes it. It never changes anything itself.
Droynis is not an antivirus or malware scanner: it audits how the phone is set up, not whether an app is malicious.
What it checks
• Device integrity: security patch age, vendor and kernel patches, encryption, bootloader lock, root, SELinux, WebView updates, time since restart
• Access control: screen lock and its strength, biometric unlock strength, lock delay, remote lock and erase, USB and wireless debugging and their authorization timeout, Smart Lock, SIM PIN
• Apps and permissions: accessibility services, device admins, notification access, SMS and call log access, location all the time, autofill and assistant apps, sideloaded and debuggable apps, special app access, apps that skip battery optimization or record the screen without asking, Google Play services
• Network and radios: Private DNS, VPN, Wi-Fi security and MAC randomization, open Wi-Fi networks that join automatically, HTTP proxies, user and added system certificates, 2G, mobile network encryption, Bluetooth, NFC and Secure NFC, location
Four tiers
Most checks need no setup. Two read-only adb grants, Shizuku or root unlock the rest; privileged tiers run only a fixed list of read-only commands.
Honest results
A check passes only on a value it actually read. When Android won't say, the result is Unknown, never Passed. A score from 0 to 100 sums it up; checks you can't fix can be muted.
Private by design
No internet permission, no Google Play Services, no analytics. Reports (Markdown or JSON) leave out IP addresses, DNS and proxy servers and trusted computers by default.
