Dear Sir,
I found the recording clips of Boldbeast shown in the music library of my phone HTC One, though I used the Password protected Boldbeast. I also used Boldbeast in my previous phone Nokia N8 but I did not find this type of problem. Please try to sort out this problem.
Nokia N8 (Symbian platform) has the built-in "Data Caging" feature which protects recorded files in your SD card from being visited by other software. Android platform doesn't have this system level feature, there is no good solution so far.
