Flag minifyEnabled stays for ProGuard, and it’s turned off by default. So, in default setup both debug and release builds aren’t using ProGuard, and parameter proguardFiles is effectively ignored.

Is ProGuard safe?

Problem is the app may be reverse engineered and the generate algorithm may be exploited. It is not possible to keep the algorithm locally in a file because with a rooted phone the cracker may be able to retrieve it.
