Google Play wants me to show my home address publicly in order to keep my apps on google Play. I do not want to do that.
I have now published the app on F-Droid, another app store for Android, which only hosts fully free and open source apps. Here's a link to the app on F-Droid: https://f-droid.org/packages/com.theskillapp.skillapp/
The new version (4.0.2) removes Google Drive backup as it required proprietary (non-free) software to be included in SkillApp in order to work. It also adds local backup functionality, more measurement units, fixes some bugs, removes Google Analytics and Crashlytics and no longer requires access to the Internet, meaning that not only do I not collect your data in SkillApp (that was also the case in previous versions, I never have collected any data), neither does Google (this is new in the last update).
