Do I still need a server when using RevenueCat

Hello, Im currently trying to add an auto-renewable Subscription to my iOS App. When using only StoreKit Apple strongly recommends using my own server to communicate with the App Store Server. Since I have no experience with building a server, I was wondering if I still necessarily need a server if I use Revenue Cat? I know its possible to not use a server and only do on-device validation but that has some disadvantages that would kind of ruin my In-App Subscription.
Thank you in advance!
