My app does not collect any information, but I have no way of knowing what libraries are doing.
All the libraries that I used in the app version 3.0 and up are:
androidx.appcompat:appcompat:1.4.2
com.google.android.material:material:1.6.1
androidx.recyclerview:recyclerview:1.3.0
androidx.preference:preference:1.2.0
androidx.constraintlayout:constraintlayout:2.1.4
androidx.multidex:multidex:2.0.1
com.google.android.gms:play-services-ads:20.6.0
com.google.code.gson:gson:2.8.9
com.squareup.retrofit2:retrofit:2.6.4
com.squareup.retrofit2:converter-gson:2.6.4
com.google.android.play:app-update:2.0.1
