De-Googled. Hardened. Yours.

BlackOS serves as a hardened fork of the Android Open Source Project (AOSP). We have surgically removed all Google Play Services and proprietary binaries that phone home.

Technical Stack

• Custom Bootloader & Verified BootWe sign our own OS images. The bootloader is locked to our keys, preventing evil-maid attacks while maintaining your ownership.
• Proprietary Service ReplacementWe've replaced GMS with BlackOS Core Services—our own location provider, push notification gateway, and update system. No data leaves your device without your consent.
• Native App SuiteWe build our own essential apps: BlackDialer, BlackMessenger, and BlackMaps. Zero reliance on third-party data harvesting.
