# GrapheneOS/Vanadium

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.

## What it is
Vanadium is a privacy and security hardened variant of Chromium that serves as the standard browser and WebView provider on GrapheneOS. It relies on OS-level hardening in GrapheneOS rather than duplicating those fixes inside the browser itself.

## Use cases
- hardened chromium browser for android
- privacy-focused web browser for grapheneos
- secure webview for android apps
- browser with extra security hardening
- replace google chrome with a privacy browser
- open-source chromium fork for privacy

## When to choose
- you run GrapheneOS and want the default hardened browser and WebView
- you want Chromium compatibility with additional privacy and security hardening on Android
- you need a WebView implementation hardened against real-world attacks

## When to avoid
- you use a stock or non-GrapheneOS Android ROM, since many hardening features depend on the OS
- you need a cross-platform browser for desktop operating systems
- you want a browser with built-in extensions or heavy customization

## Facets
- artifact type: application
- maturity: active
- function: security, privacy, browser-extension
- domain: privacy, security, web-development, android-tools
