CENO Browser

CENO (short for Censorship.no!) is a mobile Web browser using a novel approach to circumvent Internet censorship. It enables access to the World Wide Web for netizens operating from highly restrictive Internet environments.

CENO users do not need to know a friendly proxy server in the uncensored zone in order to bypass local filtering — setting CENO apart from most other circumvention initiatives. CENO is built in expectation of aggressive Internet filtering and the establishment of national intranets to fence off nations from the Web.

CENO is based on Firefox for Android (a.k.a. Mozilla Fennec), extended to make use of an entire network of cooperating nodes using peer-to-peer routing and distributed caching of responses.


→ Currently CENO requires that the phone is connected to a wireless network (WIFI)


→ Browse web pages directly, with normal connection speeds, when Internet access is not censored.

→ Still reach sites (with slower speeds) when they have been selectively censored (either by URL or IP).

→ Retrieve and browser web pages directly from other CENO users (if they have visited and cached them previously).

→ Retrieve and naturally browse content inserted off-line (like web site captures).


CENO is still highly experimental alpha software. We offer it with the best intention that it is useful to you, but due to its highly innovative nature and stage of development, you may expect some issues while using it. In particular:

• The availability of web content (especially under censorship conditions) may vary widely with factors like web site configuration, network capacity, and the presence, connectivity and browsing behavior of other CENO users. The behavior of the mechanisms currently used to share content between users may be erratic.

• The application may use substantial device resources like network traffic, disk space and battery power.

• The application may experience hangs or crashes.

• CENO is not an anonymity tool: information about your browsing might be leaked to other CENO users, as well as the fact that your application is providing particular web content to others. Content accessed with the application may stay in storage in clear text for some time (continue reading for more information on this). Other security or privacy-affecting issues might exist.

We recommend that you use this tool in controlled environments and only assume reasonable risks. eQualitie and its associates decline any legal responsibility derived from the use of this software.

We keep on working to make this software better, and your feedback to censorship.no.thanks@gmail.com is very welcome!
