This is base project for com.dedetok.wargasari,
com.dedetok.purwakaning, and com.dedetok.pitrapuja listed on Google Play. I tested on Android 7, 8,
9, 10, 11 and 13, I believe no bug or no any code that can caused your
privacy data leak. No guarantee if you use apk or other package
installer other then google play.
