I have to have WhatsApp installed on one of my phones for work purposes. It’s not possible to ask my work to give me a phone (I’m on zero-hours contract). I do have two phones - one DeGoogled pixel running CalyxOS and one iPhone XS. The iPhone I use for banking apps and basically anything that ties directly to me. Apple Pay and so on. Then I use the DeGoogled phone for everything else - most communications done over Signal, taking photos etc. This is my daily driver.
My question is this - is there any way to make WhatsApp as private as possible? I’m fine knowing WhatsApp reads all my messages etc (not really fine per se, but what choice do I have) but what I really don’t want is telemetry. So which phone should I install it on? The private one to limit telemetry, or the regular phone to stop any telemetry from my private phone being read? Or is there some way I can remotely host an instance of WhatsApp or something?
And then you have to choose the user and go through the login screen/PIN. I mean you can be done in 10-15 seconds each time, but it’s for something as frequently used as a chat app, it really breaks the workflow each time you need go switch apps/users, as compared to, say, hitting the navigation button to switch app twice.
OK, well that’s the price you have to pay if you want to keep it isolated. I know I can’t be bothered to do it, but that’s what OP requested!
I reckon there should be a way to keep both sessions logged in and more easily changeable. I mean, I asked and apparently they are running simultaneously and without pausing when you switch.
