[nmglug] .7z archive apps and GrapheneOS

[Tom Ashcraft]

Greetings all,

I'm really new to GrapheneOS.  But after considerable study, 
experimentation and general poking around, it seems to me that obtaining 
any existing .7z archiving app, or side loading an APK for the same from 
any available app store that doesn't compromise my anonymity (only 
F-Droid and Aurora Store as far as I know)--or worse, directly hand over 
my identity and data to Google again by means of immediately re-chaining 
me to the same Play Store which I have recently worked so hard to 
escape--is just about impossible.

At this point I'm under the impression that the only practical 
workarounds for the situation might be to either modify an existing APK 
that presently contains said unwanted tracking baggage, or compile a new 
one from source.  I have very little relevant experience or 
understanding applicable to either route, but I'm beginning to think 
perhaps I should try to educate myself and give it a whirl.

Is it all really this bleak, or am I just unaware and overlooking 
something simple or obvious that someone might be able and willing to 
enlighten me about?

Tom

BTW, I have two profiles in my phone setup.  The privileged 'Owner' 
administrative profile is Google free.  The second 'user' profile has 
the Google Play Store and all the dependencies and other Android crap 
that I either don't know how to or am unwilling or unable to do away 
with yet.  I suppose I could reverse all this if it would help, but I 
expect it would just be letting Google back in through the back door if 
I allowed both profiles access to Play Store dependent apps.  The way 
things are now, I'm apparently able to spend much less time in a Google 
contaminated environment.  That in itself is a desirable achievement.  
At least this is my current understanding.
