Objectives

In descending order of significance (i.e. most important objective first):

1. ungoogled-chromium is Google Chromium, sans dependency on Google web services.
2. ungoogled-chromium retains the default Chromium experience as closely as possible. Unlike other Chromium forks that have their own visions of a web browser, ungoogled-chromium is essentially a drop-in replacement for Chromium.
3. ungoogled-chromium features tweaks to enhance privacy, control, and transparency. However, almost all of these features must be manually activated or enabled. For more details, see Feature Overview.

Differences from ungoogled-chromium

These are the differences between a Linux build of ungoogled-chromium and ungoogled-chromium-android.

• Disable/Remove Android specific functionalities:
  • Contextual search
  • Lite mode
  • Offline indicator
  • Prefetch
  • Home page links
  • Unnecessary account permissions
• Android specific enhancements:
  • Add Startpage.com and Qwant.com as search engine options
  • Add new folder button in bookmark manager
  • Add back flags to enable deprecated TLS warnings
  • Add flag to enable update notifications (disabled by default and will only send a single GET request to my server periodically)
  • Add flags to always send save-data flag in header
  • Add flags to force tablet UI and desktop mode
  • Add flag to disable WebRTC. This flag is enabled by default.
• Borrowed from Bromite:
  • Always incognito mode
  • Bookmark import/export options
  • Clear open tabs between sessions
  • Disable DRM media preprovisioning which leaks connections
  • DNS-over-https by default
  • Exit menu item
  • Proxy configuration
  • WebGL flag
• Borrowed from Vanadium:
  • Disable seed-based field trials
  • Disable media router
  • Disable metrics
  • Enable user-agent freeze
  • Enable split cache, partitioning connections, strict site isolation
  • Various compiling time enhancements
• All Google play and Google service related blobs are removed. This includes Firebase, GCM (Google Cloud Messaging), GMS (Google Mobile Services) and bridge to Google Play.
• Releases are built for arm, arm64 and x86. There is no x86_64 build.

Limitations

The enhancements included in ungoogled-chromium are not to be considered useful for journalists, people living in countries with freedom limitations, and those who are facing government-level adversaries. Please look at tools specifically developed for these purposes, for example Tor Browser in such cases.

Platforms and Versions

Pre-built apks are named as {BUILD_TARGET}_{CPU_ARCH}.apk, where:

• {BUILD_TARGET} is one of ChromeModernPublic, Trichrome, SystemWebview.
  • ChromeModernPublic is for API >= 21 (Android 5.0) and only contains the browser.
  • Trichrome is for API >= 29 (Android 10) and only contains the browser. Note: Trichrome has two apks, you need to install both for ungoogled-chromium to work.
  • SystemWebview is for >= API 21 (Android 5.0) and only contains the webview.
• {CPU_ARCH} is one of x86, arm (armeabi-v7a), arm64 (arm64-v8a).
• Please also read this important note about Webview on Android N-P.
• The Bromite Wiki can also be helpful.
