Does deleting WhatsApp from my iPhone exit my groups?

WhatsApp is taking a whole lot of space on my iPhone. I wanted to know if deleting my WhatsApp app from my iPhone makes me exit my groups and stuff like that. I don't really care for single conversations, but I have important things on group chat. Will I be exited from the group?

Yes, it deletes everything… Unless if you have iCloud backup then they will be saved as a history!
