iodéOS is a privacy-focused operating system powered by LineageOS and based on the Android mobile platform. iodéOS aims at protecting the user’s privacy with a built-in adblocker and by freeing the smartphone from snitches.
The objectives in the conception of this ROM are threefold:
To keep the stability and security level of LineageOS, by minimizing the modifications made to the system. Apart the system modifications required by the adblocker, we mainly only added a few useful options commonly found in other custom ROMs, made some cosmetic changes, modified a few default settings to prevent data leaks to Google servers.
Changes in LineageOS to prevent data leaks:
Default DNS server: Google’s DNS replaced by Quad9’s ‘unblocked’ servers in all parts of the system.
A-GPS: patches to avoid leaking personnal information like IMSI to supl server.
Captive portal login: connectivitycheck.gstatic.com replaced by captiveportal.kuketz.de for connectivity check.
