 ## Obtaining Applications
 
+When downloading new apps there are a few places to get them.
+
+If you are unsure about whether an app might contain a tracker, we suggest looking at the report produced by [https://reports.exodus-privacy.eu.org](https://reports.exodus-privacy.eu.org). This site can present information such as the permissions required and trackers detected in an app.
+
+!!! note
+
+    Android applications often require permissions for simple features. Don't be alarmed if your app requires a certain permission.
+
+!!! warning
+
+    While Exodus is able to determine some trackers it may not be perfect. Make sure you look for the privacy policy for the app. Facebook for example shows [no trackers](https://reports.exodus-privacy.eu.org/en/reports/com.facebook.katana/latest/), but that does not mean there aren't any on the site.

 ### GrapheneOS App Store
 
 GrapheneOS's app store is available on [GitHub](https://github.com/GrapheneOS/Apps/releases). It supports Android 12 and above and is capable of updating itself. The app store has standalone applications built by the GrapheneOS project such as the [Auditor](https://attestation.app/), [Camera](https://github.com/GrapheneOS/Camera), and [PDF Viewer](https://github.com/GrapheneOS/PdfViewer). If you are looking for these applications, we highly recommend that you get them from GrapheneOS's app store instead of the Play Store, as the apps on their store are signed by the GrapheneOS's project own signature that Google does not have access to.
