I guess the stuff I was worried about was contact list sharing, Google Advertising ID, installed app list, and who knows what else a native app can access. Good to know that Graphene has that protection, I guess I’ll worry less about using WA.

I used a setup like that, but there were 2 things that I didn’t like

• I had to keep Whatsapp on my phone and open it every 2 weeks, because without it the bridge would just die (so why not just use it anyway?).
• The app I had used a lot off battery, which was a dealbreaker for bike/backpacking trips.
