WTFPL can not use additional license.
In this repo, you use these additional license.
However, please change name if you modify codes.

    Since 2.1.5, you cannot name app as Brevent, nor Βrevent or so.
    Since 2.1.6, you cannot use Brevent's package name.
    Currently, default name and package name is Nrevent, means Not Brevent.

WTFPL FAQ says:

    This is the name and version of the license.
    These are the rules for the license; they mean Sam Hocevar wrote the license, and you can modify it if you want, you just cannot call your version the WTFPL.
    These are the rules for the work; they mean you just DO WHAT THE FUCK YOU WANT TO.

You can just paste full WTFPL license into License File and edit license name to _Nrevent/Brevent Public License_ or _NBPL_ to avoid license leak.
(Why Nrevent/Brevent, but not Brevent/Nrevent? Beacuse NB in Chinese is very good.)

It just means:
You can do everything to the the codes. _Only for the codes, not other assets!_
Think about this, when you name it as Brevent, and actually it's not. If there is any problem about your modification, then the users should fuck who?
My codes is WTFTPL, just do what the fuck you want to, however, the assets are not.
And in your words, when I license it in WTFPL, then should I publish my private distribution keys?

He means the WTFPL is not allowed to add any additional restrictions without changing the name of the license. But, obviously you've added several additional restrictions so you have to rename the license.

[Nadebula] 话说，早先比尔盖茨也是反对软件专利的……

蓋茨可能不同意軟件專利，但是現在的M$把這個玩得很溜

[Nadebula] 然而，当 M$ 成为巨头（魔）之后，盖茨开始污蔑那些反对“知识产权”（sic）为“共产主义者”。

[Nadebula] 这倒是印证了“存在决定意识”。
