+### About optional data collection
+
+#### Backup
+
+The following options are presented when running an androidqf collection:
+
+```
+Would you like to take a backup of the device?
+...
+? Backup:
+  ▸ Only SMS
+    Everything
+    No backup
+```
+
+These options refers to data collected from the device by running the `adb backup` command in the background. If `No backup` is selected, the `adb backup` command is not run.
+
+| Option | Explanation |
+|--------|-------------|
+| Only SMS | `adb backup com.android.providers.telephony` is run. Only data from `com.android.providers.telephony` is collected. This includes the SMS database. |
+| Everything | `adb backup -all` is run. This requests backups of only apps that have explicitly allowed backups of their data via this method. Since Android 12+, this method doesn’t extract anything for almost all apps.|
+| No backup | `adb backup` is not run |
+
+### Downloading copies of apps
+
+```
+Would you like to download copies of all apps or only non-system ones?
+
+? Download:
+  ▸ All
+    Only non-system packages
+    Do not download any
+```
+
+| Option | Explanation |
+|--------|-------------|
+| All | All installed packages will be retrieved from the phone |
+| Only non-system packages | Don't download any packages listed in `adb pm list packages -s` |
+| Do not download any | Don't download any packages |
