CyanogenMod 在 7月初為 CM 10.2 ROM 推出 Privacy Guard 功能，可以讓用家很簡易地限制 App 讀取個人資料如 Contacts, Messages 和 Call Logs。
在 CM10.2 ROM 內，除了可在設定 > 應用程式，逐一為 App 開啟 Privacy Guard 外，亦可在 設定 > 安全性 > Privacy Gurad 進行設定。
整合 Android 4.3 AppOps
Google 在 Android 4.3 亦推出了 AppOps，功能就像 Privacy Guard，當 App 要求讀取某些資料時，可回傳一些空白資料作替代。
CyanogenMod 已將 AppOps 整合至 Privacy Guard 2.0 內。新的 Privacy Guard 功能更強勁，亦可作更多的調整和設置。
在 Privacy Guard 的管理介面，點按 App 就可切換權限讀取狀態，限制讀取位置, 聯絡人, 通話記錄, 行事曆和 Messages。另外亦加設了 Advanced Menu 連接 Android AppOps 介面 (上圖)。當 App 運行時，若果讀取權限受限會有 Notification 通知。
# Single click any app from the main PG UI to instantly toggle on/off permissions for Location, Reading Contacts, Reading Call Log, Reading Calendar and SMS/MMS.
# Long press any app from the main PG UI to see all currently used permissions and their on/off status. Tapping the app name from this view will take you to the App Info screen.
# A new ‘Advanced’ menu item allows quick access to the native AppOps UI (normally hidden).
# A notification will appear whenever you are using an app that has a permission denied.
# Privacy Guard can be enabled by default for all newly installed apps. This will block the Location, Reading Contacts, Reading Call Log, Reading Calendar and SMS/MMS permissions.
# Filter to show/hide system apps from main UI view.
# A quick scroll list view by alphabet, with disabled apps shown at the bottom.
