### Minimum Qualifications

- Must sync and store information with E2EE to ensure data is not visible to the service provider.

### Caso migliore

KeePassXC memorizza i suoi dati di esportazione come file [CSV](https://en.wikipedia.org/wiki/Comma-separated_values). Ciò può comportare la perdita di dati se si importa questo file in un altro gestore di password.

- Should integrate with native OS calendar and contact management apps if applicable.
