Even if you’ve removed the app from your home screen, some devices may still keep it in the cloud. These steps will help you make sure it’s fully removed:
For iOS (iPhone/iPad):
Open the App Store.
Tap your profile icon at the top right.
Select Purchased > My Purchases.
Find the app and swipe left to hide it (this removes it from your download history).
To remove app data from iCloud, go to Settings > [your name] > iCloud > Manage Storage > Backups, then select your device and turn off the app’s backup, then tap Delete Data.
For Android:
Open the Google Play Store.
Tap your profile icon > Manage apps & device > Manage.
Switch the filter to Not installed.
Find the app and tap the X or select it and choose Remove to delete it from your library.
To delete leftover data, go to Settings > Storage > Apps or Files and remove any remaining app data manually.
