+# How HoloLens stores data for spaces
+
+In the Windows 10, version 1803 update for Microsoft HoloLens, the mapping data for [spaces](https://support.microsoft.com/help/13760/hololens-spaces-on-hololens) is stored in a local database. (Previously, spaces were correlated to a Wi-Fi network SSID and saved separately.)
+
+The map database is stored securely, with access only available to the internal system. The database is never available to a user of the device, even when plugged into a PC or when using the File Explorer app. When BitLocker is enabled, the stored map data is also encrypted.
