Data Portability is a primordial feature of respectable cloud based softwares. This utility let users of Password Sync (iOS or Mac) download and export their data.
Password Sync Data Exporter can export passwords saved in Password Sync to open and well documented formats (such as CSV and PSSJSON). CSV exported data can be read by most spreadsheet applications and many other password managers.
*** It goes without saying this product is useless if you don't actually use Password Sync (on iOS or Mac OS X). ***
