The best approach to keeping your locations safe is to use the Locations Synchronization function within the app (also available free of charge on the Desktop Web App). If you have previously synched the locations on your device, you can re-synch to restore them, using the 'Synch' button at the top left of the locations list.
If re-synching doesn't restore locations that you are certain you previously have synched, you can try the Clear synchronized data under Settings within TPE, and then try the synch again. This can be helpful if your device's clock is out of synch with our server clock (which can lead to data not appearing to synchronize).
Restore from KML backup
We recommend that you backup important location data to KML file. You can do this by choosing Export Locations from the Action/Share button in TPE (at the top right of the map screen on iPhone and on the toolbar on iPad). If you have a KML backup file, you can restore lost locations from that file by transferring to your device (e.g. by emailing it to yourself) and then choosing Open in TPE on the device. That will re-import the data to your device.
Recover from iTunes
If you have saved locations on your device which you believe have gone missing, it may be possible to recover them from a backup file. The procedure to recover them involves connecting your device to iTunes on your PC or Mac.
Connect your device to iTunes
Connect your device to iTunes and select Apps from the list on the left hand-side of the screen:
Find the File Sharing section
On the right hand area of the iTunes window, scroll down below the Apps section to view the section titled File Sharing:
In the apps list under File Sharing, find TPE and select it. On the right hand side of the File Sharing section you will see a number of files listed:
You should see at least one file with a .kml extension. This is a backup of your saved locations made on upgrading TPE. You may can transfer the file from your device to your PC or Mac by selecting it and choosing 'Save to...':
Once you have transferred the file, you can email it to yourself and open it in TPE to re-import any locations the file contains. Alternatively, you can open it in a text editor or a desktop app such as Google Earth to inspect what locations it contains.
Depending on which versions of TPE you have run in the past, you may also see a file titled either 'tpe.sqlite' or 'backup-*.sqlite' (where * is a unique identifier). These files may remain from earlier versions of TPE or have been created during an upgrade to a newer version. They both may contain saved locations.
Recovering locations from sqlite files requires specialist tools (specifically, a program capable of reading SQLite databases).
You can send such files to firstname.lastname@example.org and we will inspect them on your behalf to see what information can be recovered.
