-===== Problem =====
+From time to time, some users complain that their **Locus Map data mysteriously disappeared**. Most often, they noticed that after their system update, after restarting the phone, and of course, after the factory reset. Here's the list of the most probable reasons for this issue:

+===== Memory cleaner =====
-===== Cause =====
-==== Memory cleaner ====
-,9% of these users are owners of **Xiaomi** od **Huawei/Honor** phones and tablets. The one and only cause of disappearing Locus data in these devices is a very **aggressive memory cleaning software**, part of MIUI or EMUI operating platforms running on these devices.

-==== Factory reset ====
+==== Solution ====
-Locus Map in its default settings stores its data in the **internal memory** of the phone or tablet. During the factory reset, the inner memory is **completely wiped out**.
+**Exclude Locus Map from memory cleaning**. When your Xiaomi or Huawei alerts you that they desperately need memory cleaning, please, be careful. In some devices/OS versions, it is possible to exclude Locus Map from memory cleaning:
-===== Solution =====
+  * run memory cleaner once
-==== Exclude Locus Map from memory cleaning ====
+  * if Locus Map is marked as an app to be cleaned, hold your finger on it and then select to **exclude Locus Map from the process**
+Other devices don't offer this option so you have to **exclude Locus from cleaning each time manually** - unfold all categories in the cleaning list and uncheck all boxes containing Locus Map.

+**Never allow fully automatic memory cleaning!!**
+</WRAP>
+===== Uninstallation or factory reset =====
+Locus Map in its default settings stores its data in the private sector of the device's **internal memory**.
+  * if you uninstall Locus Map, its data is deleted
+  * during the factory reset, the inner memory is **completely wiped out**.
+==== Solution ====
+**Back up your data** before uninstalling the app or resetting your device. **[[manual:faq:disappearing_data#backup_-_the_best_prevention|See below >>]]**
+===== System-forced change of default app's working directory =====
+With the arrival of Android 11 Locus Map lost the option to have its working directory in the root of the internal or external storage and was forced to [[https://www.locusmap.app/android-11-brings-a-major-change-to-locus-directories/|use the private sector in /Android/data/ directory]]. Immediately after the change, we introduced an optional **[[manual:faq:android_11_filesystem|simple data transfer]]** which was available to Locus Map users for a temporary period. **The period has now expired and the newest Android OS versions automatically change the path to the Locus Map default directory WITHOUT WARNING**.
+==== Solution ====
+  * open Settings > Backup & Filesystem > File system manager > Set the main directory > 3 dot menu by the **Private folder in 'Android/media'** > tap **Select**:\\ {{ :manual:faq:faq06.jpg |}}
+  * go to Settings > Backup & Filesystem > App data transfer > Load app data > continue:\\ {{ :manual:faq:faq07.jpg |}}It is necessary to select the original **Internal storage/Locus** directory for data move.
+===== Backup - the best prevention =====
+We strongly recommend making **backups of your data outside of your phone or tablet**. Tracks, points, settings and also downloaded maps can be backed up to a cloud (Dropbox/Google Drive/OneDrive) in Locus:

+  * **[[manual:user_guide:maps_offline#cloud_backup_of_maps|How to back up your downloaded maps >>]]**
+**With your data regularly backed up, you don't have to worry.**
