Offloaded app is not reinstalling i need help please..
Few days ago i offloaded an app and i tried to reinstall it again because i need the data on it. But it says that the app is no longer on the apple store! And it shows only one option.. it’s to delete the application. 

But seriously i need the data on it and i dont know what I might do until I hear back from Apple support. 

I have an iphone 7 and Icontacted the Apple services and they told me to search for the app developer because they cant do anything for this issue unless it’s released again on the Apple store.

I can’t find the app anymore, neither the developer. And i need the data :( the app is called “calculator+”. It’s for keeping photos, videos and documents secretly.

Could anyone help me with that please?
You can try and get the data from a backup or use it on an older device.
From this Apple Discussion:

If the app was deleted from the App Store and you were restoring an iCloud backup, whatever you saw was a glitch and the app was not going to download no matter what you saw. If the app is no longer available, it can not download again from the App Store.
When you restore an iCloud backup, the apps download from your purchases in iTunes, not from the iCloud back up itself.
