Really simple to use privacy manager for Android 6.0 Marshmallow and later (successor of XPrivacy).
Revoking Android permissions from apps often let apps crash or malfunction. XPrivacyLua solves this by feeding apps fake data instead of real data.

Please read the frequently asked questions before asking a question.
XPrivacyLua is not a permission manager, but a privacy manager. XPrivacyLua doesn't block things and doesn't revoke permissions, but does replace real data by fake data. This means you can grant Android permissions to an app and still let XPrivacyLua prevent the app from seeing privacy sensitive data. Revoking permissions can result in an app refusing to work and/or to crash. However, replacing real by fake data generally doesn't let an app crash.
Currently restrictions are quite crude because they mostly replace real data by no data. For example restricting the contacts app from getting contacts will result in an empty contact list. In the near future it might be made possible to select the data an app may see, for example just one group of contacts.
The goal is to have a tool that can properly protect the privacy of many in the near future. However, it isn't paid work, so I do whatever I like whenever I like it.
You can request features in this XDA forum. I will read them, but I will not respond to them and they might or might not be implemented. If I know for sure something will not be implemented, I will let you know.
You can report any problem you have here. There will be no issue tracker on GitHub.
For now I have decided to not implement restrictions that are useful to prevent tracking only. There are simply too many data items that can be used for tracking and it would take too much time to develop restrictions for all these data items.
The basic idea is to restrict only things that 'define' you, so which contacts you have, where you are, which apps you use, etc.
XPrivacyLua is a work in progress. You can help by searching for APIs to block in the Android documentation.
