Hi,

First of all I would like to thank the contributors of GrapheneOS, I am very happy to have such a tool to take care of my privacy and security on a phone.

I've been using GOS for a few weeks and I've been following and researching a lot on this forum.
I would like to optimize my use, I have already configured and taken into account with the majority of the remarks of this thread: https://discuss.grapheneos.org/d/28682-maximum-security-and-anonymity

Except for profiles and private space. I already use mostly privacy-friendly apps. I still use applications that I am gradually trying to eliminate or that I could not do without: such as Amazon, Decathlon, Strava, Bank, Foods, Spotify, other services that can only be used via the Play Store and with Google services. I would like to optimize this by integrating the private space:

Is it appropriate to group the applications mentioned there?
Where should I position my 2FA app which is used to access all these services?
How do I set up this private space? For the moment the play store and google services are installed with the majority of permissions so as not to encounter any operating problems, should I be interested in restricting these permissions?

I would like advice on how to optimize my use of GrapheneOS through the private area on the main profile.

I am in a process of continuous improvement. The subject fascinates me. I have no necessity in itself. But the whole approach seems beautiful and obvious to me (Tails, GOS, VPN, Signal, Email/Alias, Vanadium/DDG open source app, minimalism, cryptomator, etc.)

I am interested in any other recommendations. I know that it's broad and that by searching the forum it has already been said but overall the topic shared above includes the advice received.

Thank you very much for your time.
