This privacyguides forum says google knows some metadata but not the contents
I think there are some attempts by google and apple by doing client side scanning and uploading it to their servers but I don’t think that’s done yet. For apple, if you have those icloud backups on your apps then I know for sure they can see imessage stuff.
But what I’m saying is, maybe leave your devices at home and share your signal or matrix username information so when you guys come home, you can hop on to those encrypted platforms and organize and share content.
I think Briar works on bluetooth messaging but only on Androids so it’s cool but not too useful for a general purpose messenger.
If you use Signal, they don’t collect your information at all. I believe it’s only your phone number, registration date, and last time you pinged their servers. They don’t get any messages you send.
As for mail, I think this one’s a tricky bastard but if you use VPN, something like protonmail won’t receive anything on their end, maybe some metadata from when you sent the email though, and assuming the other person is also using protonmail or pgp encryption.
I personally also have a threat model outlined and have 2 phones. One cheap flip phone with my redpocket sim which I use for government and banking stuff. My tmobile phone is for anything else, like friends and social stuff. Maybe you could have the same thing set up.
I have the exact same setup as you lol
You can also use the Aurora Store and not use appls from the playstore.
I also have a separate SIM in here from Redpocket. You could buy the $30 annual plan on ebay with a visa gift card or something to make it slightly more hard to trace you down. And ofc you can use Signal and no log kyc VPN to do your activities.
If you don’t need proton’s whole suite of tools I say go for mullvad.
You can also just test them both out for yourself. Try mullvad for one month, proton another. The nice thing with mullvad I believe is that it’s way more anonymous in terms of various forms of payment and I believe it has a fixed price.
These are all the court orders Signal has complied to and details all the information they give up

TLDR; they only give the last time the account connected to Signal servers and the time of account registration or re-registration
On the cli my favorite calculator of all time is Qalc. It’s fucking amazing.
You can be like “1 km to mi” and it will give it to you.
For some reason the screenshots show the gui but imo the cli is where it’s at
Yeah, Snowden himself says he desolders microphone and camera on his devices. I’m sure a pc with no mic and cam would do just fine. Or go the desolder route. You can use Signal on a burner phone for the initial setup and then take the battery out so now you just have Signal on your presumably private linux pc with nothing on there.
Funny that news nowadays is citing tik tok and reddit comments

You can pin the app (android) or have it in guided access mode (ios). Although, yeah, I wouldn’t be surprised if there’s an exploit to get out and access memory it shouldn’t. Maybe if you install the govt spyware app in a different user profile (Android) then it will be restricted to that certain memory.
Not hardened though. I was heavily considering fairphone but over the back and forth between them discussing with Graphene developers, their hardware is not secure enough yet for graphene to be made for the fairphones. If and when fairphones are on graphene then I will definitely buy them.
Also, even though I commend their phone, the accessories for earbuds and headphones certainly bring up some questions as to their intentions.
This is why I’m avoiding traveling through tsa during Trump’s presidency
