Unity trademark in non-game app.

Hello and sorry for my english.
I created my first non-game app with Unity for Android and iOS.
I bought Unity Plus.
Do i need to inform inside of app it was created with Unity?
Do i need place the logo of Unity in app?
I changed splash screen to my own.

The Unity Pro and Plus subscriptions have no limitations to customization of the Unity Splash Screen.
It is not necessary to put their logo, only if you want.
