If you have enabled Settings > App Store > Offload Unused Apps [Enable] and if you haven't used an app in 12 days, your device can automatically offload it to save storage space. This removes the app itself but keeps all your data intact. You can easily re-download the app from the App Store whenever you need it again.
See the pic below
Instead of downloading the app again simply tap on the offloaded app.
