If you're the sort of of person that is concerned about access to your private data when downloading and installing applications on your Android device, be it from the official Andorid Market or not, you might be interested in XDA forum member svyat's application.

PDroid allows control over access for any installed application to your private data. This includes:

  • Device ID (IMEI/MEID/ESN)
  • Subscriber ID (IMSI)
  • SIM Serial (ICCID)
  • Phone and mailbox number
  • Incoming call number
  • Outgoing call number
  • GPS location
  • Network location
  • List of accounts
  • Account auth tokens
  • Contacts
  • Call logs
  • Calendar
  • SMS
  • MMS
  • Browser bookmarks and history
  • System logs
  • SIM info (operator, country)
  • Network info (operator, country)
Note that applications do not crash when access to private data is blocked and no background service is needed. The app should have no impact on battery life or performance. To use the app, you'll need to download and install the relevant patch before installing the app.
For more information, head on over to application thread. PDroid is available for download free in the Android Market.
