Hi caiomachado,
To resolve your issue, deleting an app from one device does not automatically remove it and the files in it from another device unless the third party app has it setup that way. To verify with the third party, we'd recommend reaching out to the developer of the app by completing the steps listed here: How to contact an app developer - Apple Support. The steps are also below.
"Contact the developer of an iOS, iPadOS, or watchOS app
- Open the App Store on your iPhone or iPad.
- Search for the app, then tap it. If you can't find it, tap the account button
or your photo at the top of the screen, tap Purchased, tap "Not on this [device]," then tap the app. - The app's product page appears. Scroll to the Ratings & Reviews section, then tap App Support. If you don't see App Support, make sure that you're signed in with the correct Apple ID.'
Best regards.
