Hardened allocator designed for modern systems. It has integration into Android's Bionic libc and can be used externally with musl and glibc as a dynamic library for use on other Linux-based platforms. It will gain more portability/integration over time.

Privacy and security enhanced releases of Chromium for GrapheneOS. Vanadium provides the WebView and standard user-facing browser on GrapheneOS. It depends on hardening in other GrapheneOS repositories and doesn't include patches not relevant to the build targets used on GrapheneOS.

Modern camera app focused on privacy and security with QR & barcode scanning.

Simple Android PDF viewer based on pdf.js and content providers. The app doesn't require any permissions. The PDF stream is fed into the sandboxed WebView without giving it access to content or files. CSP is used to enforce that the JavaScript and styling properties within the WebView are entirely static.

Remove the fear of Android app compatibility on de-Googled devices.

Hardware-based attestation and intrusion detection app for Android. It provides both local verification with another Android device via QR codes and optional scheduled server-based verification with support for alert emails. It uses hardware-backed keys and attestation support as the foundation and chains trust to the app for software checks.

Report and track banking app compatibility with GrapheneOS, including which workarounds may be required.

GrapheneOS rooted and served via its own OTA server on GitHub pages

attestation.app remote attestation server. Server code for use with the Auditor app: https://github.com/GrapheneOS/Auditor. It provides two services: submission of attestation data samples and a remote attestation implementation with email alerts to go along with the local implementation based on QR code scanning in the app.

Hardened Android standard C library. Some of the past hardening has not yet been ported from Marshmallow, Nougat and Oreo to this Android Pie repository. Most is available via archived tags in https://github.com/AndroidHardeningArchive/platform_bionic (check both the most recent Oreo and Nougat tags).

A resource for users intent on optimizing their usage of this highly secure and privacy focused mobile operating system.
