XPrivacy

The ultimate, yet easy to use, privacy manager for Android

Index

Description

XPrivacy can prevent applications (including associated background services and content providers) from leaking privacy sensitive data. XPrivacy can restrict the categories of data an application can access. This is done by feeding an application with no or fake data. There are several data categories which can be restricted, for example contacts or location. For example, if you restrict access to contacts for an application, this will result in sending an empty contact list to the application if it requests access to your contacts. Similarly, restricting an application's access to your location will result in a random location being sent to the application.

XPrivacy doesn't revoke (i.e. block) permissions from an application, which means that most applications will continue to work as before and won't force close. There are two exceptions to this, access to the internet and to external storage (typically an SD card) is restricted by denying access (revoking permissions). There is no other way to realize this, since these permissions are handled by Android in a special way. Android delegates handling of these permission to the underlying Linux network/file system.

If restricting a category of data for an application results in problems for that application, it is possible to allow access to the data category again.

By default, all newly-installed applications will have no access to any data category at all, to prevent a new application from leaking sensitive data after installation. Shortly after installing a new application, XPrivacy will ask which data categories you want the new application to have access to. XPrivacy comes with an application browser, which allows you to quickly enable or disable applications' access to a particular data category (i.e. to view and control all access to the camera, for example).

To help you identify potential data leaks, XPrivacy will monitor attempts made by all applications to access sensitive data. XPrivacy will highlight (with a yellow triangle) a data category for an application (or an application name in the application browser) as soon as data of the data category has been used. XPrivacy will also display if an application has internet access, indicating that the application poses a risk of sharing the data it obtains with an external server. If an application has requested Android permissions to access data in a data category, it will also be displayed (with a green tick), but this will only be shown when looking at an individual application, since checking permissions for all applications is quite slow.

XPrivacy is built using the Xposed framework. XPrivacy taps into a number of selected functions of Android through the Xposed framework. Depending on the function, XPrivacy conditionally skips execution of the original function (for example when an application tries to set a proximity alert) or alters the result of the original function (for example to return empty calendar data).

XPrivacy has been tested with CyanogenMod 10 and 10.1 (Android 4.1 and 4.2), and will likely work with any Android version 4.1 or 4.2 variant, including stock ROMs. Root access is needed to install the Xposed framework. Because of a bug in the Xposed framework, XPrivacy currently needs a fixed Xposed binary, which is provided as download for both Android version 4.1 and 4.2.

XPrivacy was a lot of work, so please support this project

Installation

It seems like a lot of steps, but it is done in no time:

Requirement: Android 4.1+ (JellyBean), check with System Settings > About phone > Android version
Make a backup
If not done already: root your device; the procedure depends on the brand and model of your device
Enable System settings > Security > Unknown sources
Install the Xposed framework
- Be sure to follow all installation steps
- Be sure to install the latest version 2.1.4
- Download and copy the Xposed disabler to your SD card to disable Xposed in case of troubles
- MIUI is not supported by Xposed
Install XPrivacy from here
- Alternatively download from here
Enable XPrivacy from the Xposed installer
Reboot into recovery
Flash the Xposed fix for your Android version from here
- Android 4.1.x / CM10: Xposed_fix_4.1.zip
- Android 4.2.x / CM10.1: Xposed_fix_4.2.zip
- This fix is only for Xposed version 2.1.4
- Alternatively download from here
Reboot

I do not recommend using XPrivacy in combination with any of the similar solutions, because it will most probably result in conflicts (with as possible consequence data leakage).

Upgrading

Make a backup
Install the new version (replacing the previous version)
Reboot your device

You can check for updates using the options menu. If there is an update the browser will download it.

Usage

Start XPrivacy
Select a data category at the top, for example Accounts
Restrict data of the selected data category for an application by ticking a check box
Tap on the application icon to see the restrictions for all categories for the application
Tap on the application icon to start the application to test (after previous step)

To see it in action: try restricting the category Identification for Android Id Info or try restriction the category Contacts for the Contacts application (the Contacts application will continue to show a spinner, which is actually a bug in the Contacts application).

Applying some restrictions requires restarting applications and/or your device

If an application requested Android permissions for a data category, the category will be marked with a green check mark icon. If an application used/tried to use data, the data category will be marked with an orange triangle icon. These icons are just a guideline, because an application can access privacy sensitive data without Android permissions, for example the serial number of your device and because is not possible to monitor data usage in each and every situation, for example not for access to the internet or the external storage.

Enabling internet or storage restriction means blocking access to the internet or to the external storage (typically the SD card). This may result in error messages and even in forced closes of the application.

Using XPrivacy is entirely at your own risk

Permissions

XPrivacy asks for the following Android permissions:

Internet: to check for updates (only manual from the menu)
Storage: to export settings to the SD card (only pro version)

If you don't like this, you can always restrict XPrivacy itself ...

Frequently asked questions

(1) Will XPrivacy make my device slower?

Maybe a little bit, but it will probably not be noticeable.

(2) Does XPrivacy use a lot of memory or battery?

Almost nothing.

(3) Can you help me with rooting my device?

There are already enough guides to help you to root your device. Use your favorite search engine to find one.

(4) Do I really need to install the Xposed fix?

If you like to have all data restricted, yes. The current Xposed version cannot hook all functions with the same name having different parameters, like requestLocationUpdates of LocationManager.

(5) How can I reset all XPrivacy settings?

Manage apps > XPrivacy > Clear data

(6) Can I backup XPrivacy and settings?

Yes, you can, for example with Titanium backup, but you can only restore onto the same device. Exporting/importing settings will work across devices. To export/import settings you will need the pro version.

(7) What is expert mode?

In expert mode you will be able to block applications from starting at device boot time, restrict shell access for applications (including super user) and restrict system applications, including Android itself. Be careful! Furthermore you will be able to make exceptions for individual functions within a restriction category.

(8) Will you block the iptables command or force online state?

Maybe in a later stage.

(9) Will you make it possible to enter fake data?

Maybe in a later stage. For now I like to keep things as simple as possible for maximum stability. Since version 0.21 you can enter a fake location. Since version 0.30 you can enter a fake MAC address.

(10) Which functions are exactly restricted?

Many, see here for all details.

(11) What did you fix in the Xposed framework?

See here.

(12) How safe is XPrivacy?

Great care is taken to develop XPrivacy, nevertheless data could leak, although nobody has reported any data leak so far. So far no critical bugs have been reported.

(13) Why is XPrivacy not in the Play store?

Google will probably remove XPrivacy from the Play store eventually, since it will be able to block advertisements (for example by revoking internet permissions).

(14) I get 'Incompatible ...' !

A check of XPrivacy failed, resulting in potential data leakage. Please report the exact message in the XDA thread, stating the device and ROM you are using.

(15) Do I need to install Xposed/the fix again when I install an update of my ROM?

Yes, mostly you will have to. XPrivacy will warn you when Xposed isn't installed, the wrong version of Xposed is installed or when the XPrivacy is not enabled in Xposed.

(16) Can I restrict an application with root access?

Yes, you can, but the application could circumvent anything, since root access means it can do anything it likes. Nevertheless the application was probably not built to circumvent everything this way. Version 0.26 will allow you to restrict shell access for any application, which effectively means revoking root access.

(17) Will restrictions be applied immediately?

It can take up to 15 seconds before changes in restrictions will be effective, because of caching. Changing the internet and storage restriction requires an application restart. Please note that in many cases pressing back, only moves the application to the background.

(18) Can XPrivacy ask for restrictions on demand?

It cannot always, since it works deep within Android, and therefore it is IMHO not a good idea to ask for restrictions when it could, because this will probably only result into confusion.

Newly installed applications are by default fully restricted. Restricting an application should not result into any force close (crash), please create an issue if this happens (see for support below), it only means that an application cannot see the restricted data. If an application should see the data, you can remove the associated restriction at any time.

(19) Does XPrivacy have a firewall?

Yes, you can restrict internet access for any application. If you want to partly enable internet, for example for Wi-Fi only, you will have to use a firewall application, like AFWall+. The reason is that XPrivacy works within Android and that detailed firewall rules can only be applied within the Linux kernel.

(20) Could you ... with Android permissions?

Android permissions do not cover all restriction categories and if they do, then mostly only partly. Therefore Android permissions are only displayed as a guideline. Any function, like filtering and selecting, would be inherent incorrect.

(20) I get 'Unable to parse package'

This means the downloaded app is corrupt. Try disabling your popup blocker or download using another computer.

Support
