 **Unattended Settings Export**<br/> By enabling this feature, you allow **AAPS** to execute settings exports without user intervention. For this the master password is securely stored on your phone (only) at the next manually export. The stored password will be used for up to 4 weeks. After 4 weeks you will be notified the password is about to expire. During a grace period of 1 week, the password can then be refreshed by manually exporting settings from the maintenance menu.
 
-After the grace period of 1 week has passed the stored password expires and any automated settings export will abort while notifying the user, asking to reenter the password.  [(**Automated settings exports**)](../DailyLifeWithAaps/Automations.md#automating-preference-settings-export)  will be logged to the AAPS 'Careportal' and 'User entry' lists under Treatments.

+### Log files
+
+AAPS will save logs for troubleshooting.
+
+Do not disable this feature: it will help understanding the reasons if something goes wrong.
+
+If you need to send the logs to the developers, make sure you file accurately the mail contents to describe the issue. It is preferable to send logs only after being requested to do so, following an [issue report in GitHub](https://github.com/nightscout/AndroidAPS/issues).
+
+You can find AAPS logs in your phone memory -> Android -> data -> info.nightscout.androidaps -> files.
