Ring with alexa app

Hello i bought a ring through amazon and my inlaws are now able to see my ring cams on there alexa app. I dont have alexa but the ring was bought thru there amazon account. However i sent up the ring thru the ring app so the ring account is mine. Is there any way to disable there view from my phone? Ive never authorized them as a user and i feel like this is a dangerous feature. What if i bought some one a nanny cam or indoor cam would i be anle to see inside there home?
