Should you choose BaaS?

Question

iOS

I am creating an app for iOS.
The essence of the application: creating a personal directory with notes. Notes are distributed according to the internal calendar. And the calendar becomes the main functionality. Network access is not required. Data is rarely added.
Hence, there is uncertainty in the way data is stored.
Locally? Users love to lose data.
Create a backend? Additionally, asking the user for authorization + the application becomes dependent on the Internet.
Is there a middle ground or any articles on the correct choice of different storage methods?

Answer 1

Store data locally (cordat or files) and periodically, once a day or a week, make backup copies in iCloud.
