That's an extremely solid list, mate. You can be proud of that. May I ask how long it took you to transition to this state?

In case you're still willing to adjust one thing or another, here's some food for thought:

1. You're still running a relatively Proton-heavy loadout. They're hosting your mail, VPN, docs, calendar and AI services. In case of a breach (attacker gains access to your account) or a company employee / the company itself going rogue, you will have several eggs in that particular basket affected, and a few very sensitive ones at that. Diversification might be an option, e.g. getting a separate mail provider, running your docs and calendar through a (self-hosted?) Nextcloud instance, etc.
2. Personally, I've never felt comfortable with the idea of my password manager being cloud-accessible, regardless of how tight the security on the other end claims to be. KeepassXC (on Linux) and KeepassDX (on Android/GrapheneOS) work extremely well. They've even gained Passkey support recently. Add Syncthing to the mix for cloudless cross-device sync and you've got yourself an entirely offline password manager.
3. You may want to fix the "FUTO" spelling in those two headlines. ;)

I would recommend not using any software from FUTO. It is not open source, one of its founders is a fascist, and they have thrown money at OSS projects just to have their logos displayed on their pages, without following proper donation procedures. GrapheneOS has also stated on several occasions that FUTO has actively attempted to smear their reputation and harm their infrastructure. I can provide sources for all these points if anyone needs them.

Instead of Proton Docs have you tried LibreOffice? Also a light user but they have been really consistent for when I need it.

I don’t get why brave cultists try to shove brave into these guides. It’s not bad because it’s chromium. Brave is bad because it’s a crypto bro browser run by a right wing chud ceo. If you are running Brave you might as well just use Omarchy. Both are right ring chud run. At least the Omarchy right wing chud isn’t running a crypto bro ad company. Both are just terrible.The fact that this guide suggests buying a $60 license to brave is insanity.

If you're using Graphene, Vanadium is the way to go instead of Brave Origin. The security is significantly better as it's made for the OS (and you know how Graphene is with security). Also, no more need to use Brave! If you're ever using a different Android OS, there's Titanium, based on Vanadium.

Instead of Bitwarden, use Vaultwarden. Self hosted Vaultwarden gives you all the Bitwarden things (including the Auth tool). I will admit I do not know what Bitwarden offers without self hosting Vaultwarden.

I have my passwords encrypted and backed up on a VPS, with many others things.

What's wrong with Nord? They don't keep logs. Or do they?

Any thoughts on Tuta for email and calendar? I wanted to hop on proton but they are associated to the french right and it gave me the ick.
