Data Sanitizer is a simple tool that implements the Russian GOST R 50739-95 method to remove data remanence it overwrites the free disk space to insure that no recoverable data is left behind.


Data Sanitizer is optimized for speed and uses the system's resources heavily therefore it is strongly recommended NOT to use the phone while the app is running.
The app is easy to use just download and run (preferably after a factory reset).
