While you're still stuck "using" Whatsapp, I've had great success using the Matrix bridge [0] on the homeserver I run [1]. Your contacts still message you, but you don't have to give Whatsapp your contacts list, other apps installed, or location via ip/wifi network.
It won't work for calling (as it's not supported on Whatsapp Web), but images and groups (which I use) both work perfectly.
