You can create a backup of all the data you entered. Selected Tools/Backup and use the menu button. Click on New backup; this will create a backup file with the data in internal memory.
You can export the backup file from internal memory to external storage (usually your SD card). You can do this by selecting the back item in the Tools/Backup list, using the menu button and selecting Export; this will copy the backup file from internal memory to external storage. If your device has no external storage, the application will hide the Export menu option.
