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.
For com.dedetok.turuntirta and com.dedetok.bramara, I keep using MediaPlayer legacy. Source code:
