Hi and Welcome to the Community!
There are a few methods:
1) You can synchronize to a supported desktop PIM
2) You can export to an ASCII or CSV file:
3) You can conduct a backup to your PC and then find a 3rd party PC app to extract and convert the proprietary format backup file into something you can use on your PC.
Good luck and let us know!
