Integration with any other storage for the analysis

While using this app, I think it could be more powerful if it supports history tracking.
For example, week or day analysis can be possible. And visualizing the history can give some insight to me.
Maybe the simple storage for this purpose would be firestore I guess.

Maybe we could do this more simply.
By using local file as storage (json or csv format or whatever), we can do some analysis with it.
