I think it's important to flag a subtlety of the brazilian law: it makes
a difference between "connection" and "application" providers and, in
the case of application providers, it also makes a difference for the
ones whose activities are "organized, professional and with economic
purposes". According to federal law 12.965/2014 (a.k.a. "Marco Civil da
Internet), a non-commercial application provider is not obliged to
retain data, unless a judge, the "police or administrative authority" or
the public ministry requires it to.
