For questions about managing root access for apps with SuperSU, a root management tool developed by Chainfire

SuperSU is a root access management tool that allows for advanced management for all apps on an Android device that need root.

SuperSU has a free version and a Pro version. The free version offers a limited subset of Pro functionalities that is suitable for most amateur users, while the Pro version offers more advanced functionalities like per-app logging control and role control, as well as OTA survival. The Pro key can be baught from Google Play with 3.99 USD.

Starting with 2.82, the SuperSU app offers a "pseudo-pro" mode that allow users to have a fully functioning Pro version without paying for the Pro key.

SuperSU has been abandoned and the last version is 2.82 SR5, which can be found in the above link.

Note: As of October 1, 2018, SuperSU has been removed from Google Play. For devices running Android version newer than 5.0, you should try instead.
