CYRONIX OS.
BUILT ON ANDROID.
Cyronix OS is explicitly an Android operating system based on the Android Open Source Project (AOSP) and LineageOS. We do not invent an unverified kernel or alien application runtime—we take the world's most versatile open-source mobile foundation and reconstruct its security, privacy, and user ownership model from the inside out.
System Stack
The Complete Android-to-Cyronix Stack
To understand Cyronix OS, you must understand how its layers interlock. Every component has a defined origin and responsibility.
The base operating system code comes directly from the Android Open Source Project. This includes the Android Runtime (ART), core Java/Kotlin runtime libraries, standard Android APIs, the Dalvik executable format interpreter, and the core IPC binder infrastructure.
The Linux kernel forms the bridge between physical hardware and userspace. Cyronix OS integrates custom kernel hardening: Yama LSM ptrace restrictions, software Privileged Access Never (ARM64_SW_TTBR0_PAN), list-corruption debugging, panic-on-oops, and disabled diagnostic crash dump modes.

Vendor board support package for Qualcomm MSM8996pro Snapdragon 821. Interfaces the Adreno 530 GPU, audio DAC, modem baseband, camera ISP (Sony IMX298), and FPC1020 biometric scanner via standard HIDL interfaces.
PackageManager, ActivityManager, WindowManager, and NotificationManager. Cyronix OS injects framework overlays: 1.6.0 Design System tokens, squircle icon masks, 20dp dialog corner radii, and notification content privacy by default.

Dedicated system applications developed specifically by Cyronix Dev & Security: Security Center 2.0 (real-time posture audit), Diagnostics (telemetry monitor), System Update (resumable OTA daemon), Wallpapers (6 procedural AMOLED artworks), and LatinIME custom keyboard themes.

Modifications Breakdown
Exact Architectural Changes
We clearly distinguish between Android-native capabilities, device-specific vendor code, third-party libraries, and Cyronix-developed features.
1. CYRONIX System & Core
• Stripped Google Play Services, Analytics, and Advertising frameworks.
• Locked down runtime sysctls: kptr_restrict=2, dmesg_restrict=1, perf_event_paranoid=3, suid_dumpable=0.
• Enforced protected symlinks, hardlinks, and TCP SYN cookies in the network stack.
2. CYRONIX UI & Design System
• Complete 1.6.0 Design System with OLED background #0B0F14 and surface #121820.
• Inter 4.1 UI typography, Space Grotesk tabular data/clock typography, JetBrains Mono technical text.
• 167 per-locale overlays replacing legacy branding across all 50+ system languages.
3. CYRONIX Security & Hardening
• Kernel USB restricted mode: locked phone rejects BadUSB and extraction tools.
• Auto-erase after 10 consecutive failed passcode unlock attempts (opt-in).
• Cryptographic 4096-bit RSA release signing; test-key builds strictly isolated to dev channel.
4. CYRONIX Recovery & OTA
• CYRONIX Recovery OS with touch navigation, ADB sideload, and signature enforcement.
• Resumable byte-range OTA server (HTTP 206) with zero client logging.
• "Keep my recovery" toggle prevents OTA updates from overwriting custom recovery.
