What’s in /e/?

/e/ is an a mobile ecosystem (ROM + onlines services) that:

  • is open source
  • is pro-privacy
  • is compatible with most existing Android applications
  • cares about usability
  • already exists!

It’s the alternative to the Apple/Google duopoly on the smartphone.

It consists of:

  • an installable mobile operating system for smartphones, which is forked from Android and strongly “ungoogled”
  • a set of sorted and improved default open source applications
  • various online services that are linked to the mobile operating system, such as: a meta search engine for the web, drive (with synchronization), mail, calendar, notes, tasks.

/e/ is also available pre-installed on a range of /e/-smartphones.

1. Description of the /e/ ROM (installable mobile operating system)

The /e/ ROM is a fork of Android (and in particular the LineageOS flavor of Android). At the moment, two versions are supported: Android Nougat and Android Oreo. Android Pie will be supported in a near future.

DeGoogling / UnGoogling

The goal of “unGoogling” is to remove or disable any little or big feature that is sending any data to Google servers, and to offer non-Google default online services, including for search.

  • Google default search engine is removed everywhere and replaced by other services (see below in default apps and services)
  • Google Services are replaced by microG and alternative services (see below for more details)
  • all Google apps are removed and replaced by good alternative applications
  • Google servers are not used anymore to check connectivity
  • NTP servers are not Google NTP servers anymore
  • DNS default servers are not Google anymore, and their settings can be enforced by the user to a specific server
  • Geolocation is using Mozilla Location Services in addition to GPS
  • CalDAV/CardDAV management and synchronization application (DAVDroid) is fully integrated with the user account and calendar/contact application

More details about the state of /e/ OS deGooglisation can be found in this white paper.

User interface


  • A new launcher “BlissLauncher” was developed to offer an attractive look & feel. It includes a set of icons that were designed for the project. It has application widget support and is using /e/ search engine by default.
  • Changes have been done in settings to offer a better looking interface


  • A specific file synchronization service has been developed for multimedia and file contents. It can use /e/ cloud services server at https://ecloud.global or self-hosted /e/ cloud services (beta).
  • The weather provider is the LOS weather provider using data fetched from Open Weather Map
  • Account Manager has been modified to support /e/ user accounts, with a single identity, thus providing /e/ email, /e/ sync, /e/ calendar, /e/ contacts, /e/ notes, /e/ tasks to users. /e/ cloud server is either at ecloud.global, or self-hosted by the user (ongoing)

2. Description of /e/ default applications

All pre-installed applications are open source applications but the Maps app (read details about this in the FAQ).

3. Description of /e/ online services at ecloud.global


  • /e/ “spot” at https://spot.ecloud.global search engine is a fork of SearX meta-search engine, with major look&feel improvements and peformance improvements
  • /e/ cloud (ecloud.global) includes drive, mail, calendar, contacts, notes, tasks and office. It’s built upon NextCloud, Postfix, Dovecot and OnlyOffice. It’s been integrated to offer a single login identity in /e/OS as well as online, where ysers can retrieve their data at https://ecloud.global services, or self-hosted on their own server

/e/ Development status


Next majors milestones:

  • in the future /e/ will be available in two versions:
    • standard /e/ with default applications
    • /e/ with minimal number of default/pre-installed applications

Status of ungoogling & pro-privacy features

In 2019, we have addressed a number of issues with ungoogling.

This includes among others:

  • removed connectivity check against Google servers
  • replaced Google NTP servers by pool.ntp.org servers
  • replaced Google DNS servers by by default and offer users to set the DNS servers of their choice

More details about the state of /e/ OS deGooglisation can be found in this white paper.

What to expect in futher releases?

In 2020 we plan to:

  • introduce an “easy installer” for Linux, MacOS and Windows. It will let users install /e/ OS without using obscure tools and the command line (Beta is now available)
  • introduce more pro-privacy features such as a “privacy dashboard” (Work in Progress)
  • add more supported smartphones (FairPhone 3, PinePhone…) (Fairphone3 now supported, others in the pipe)
  • add more features such as “my SMS to cloud” and “my geolocation to cloud” (Work in Progress)
  • add the capability to uninstall most pre-installed applications (if feasable)
  • add several user profile to impact the choice of default applications installed during first-time usage wizard
  • add Progressive Web Apps to the application installer V2 (Work in Progress)
  • offer corresponding Google-free SDKs for app publishers, because we believe that web apps is the future for most mobile applications.
