Materialious contains zero trackers. Believe this was a issue with ublock falsely flagging local fonts as trackers or something, someone else open a issue on the repo with a similar issue. Feel free to review the source code for any trackers.
Materialious doesn't use remote fonts by default, only as a backup if local font loading fails. For some reason ublock in hard mode makes local font fail loading & remote font is used.
Materialious - Desktop & Android client ( materialio.us )
Materialious now can be used as a Desktop or Android application. Allowing it to be used for any Invidious instance!...
