Can iOS apps retrieve user access logs after being deleted?

Question

Specifically, I used an iPad app while it was offline, then deleted it. I assume that it keeps logs of access into the app and whatnot. Can an app be able to gain access to these offline logs after the app is deleted by the user?

No in general and by design. When the app is deleted, the os removed the container in which the app saves data. Unless the app saves data in a group container or runs on a jailbroken device and stuffs logs outside the sandbox, even reinstalling the app won’t recover the deleted data.
