Safest way of using WeChat on Android? (lemmy.ca)

I live in Canada. My girlfriend is Chinese (also living in Canada), and while we are able to communicate via SMS, her mobile carrier isn't the best, and so there have often been issues for us with regular texting. She expressed a strong preference to use WeChat, at least as a backup option for when texting fails us. While I have some pretty significant reservations, it's not the hill I want to die on. So my question is: what can be done to use WeChat without compromising my whole phone? I'm okay with it if our conversations aren't private, but I'd like to know that I'm not giving unfettered access to all of my phone's systems and data to the CCP. What can be done to limit the reach of this ubiquitous app on my device?

Second phone just for WeChat.

Failing that use a android work profile and run WeChat inside of that. It should isolate WeChat from the rest of the days on your phone. WeChat would still have access to your location, microphone comment etc but not your data

This is the way. Depending on how much convenience you are willing to sacrifice.

There are one or two apps on F-Droid for using the work partition, and you can force-freeze apps within that, so you can turn wechat actually off when you don't want it. That also separates wechat from your phone contacts list, without denying it nominal contacts access permission (without which, iirc, it refuses to work).

For extra paranoia, run your dedicated wechat phone permanently through a VPN with location services on the phone turned off. Answer it only in a soundproofed room, Faraday caged with no WiFi connections except the dedicated wechat WiFi. Speak with a funny voice, and if you must show your face, wear a balaclava.

But that might be overdoing it a little.

What about something like Waydroid to avoid spending extra money? Wonder if these are detected on registration.

[–] bionicjoey@lemmy.ca 4 points 6 months ago (2 children)

Was considering Waydroid, but ideally I want something that I can take with me on the go. Some folks have suggested the app Shelter on fdroid though and that seems like an ideal solution for the time being.

It does work pretty well.

[–] EngineerGaming@feddit.nl 2 points 6 months ago

Ah, okay. But given the invasiveness of the app - I now really wonder if it is possible for it to detect and shut down registration from desktops this way.
