Subscriptions should only be stored on your home instance (that’s why Lemmy surfaces monthly active users instead of subscribers) and the instance owners could see it somewhere but they are not world visible, no. However, upvotes are world-visible as far as I know, it’s just that the UI doesn’t show them.
Also using Jerboa right now. Enjoying it
