After youve unlocked it to root. So you still lose your data the first time you unlock it.

yep, I installed it too...
however one important thing you should not forget (copy/past from a review) :

"Works great but be careful Once you have unlocked and rooted your phone this app works great to lock the bootloader again. But use caution when updating OTA. I allowed an OTA update to Android 4.4.2 while locked and I lost root access (expected) but because I didn't unlock before the update, I am now locked without a way to unlock unless I wipe the phone. Great app. Just make sure you know what it does and how to use it."

--> unlock before to apply an OTA
