Debating delete this app

I’m starting to stress over TTC and go in for my first IUI at the end of this month. I think I need to take some time off to stop thinking way into everything.

What I’m wondering if has anyone taken some time off and deleted the app and redownload it, does it still have previous information? Or is that all lost ?

I don’t want to loose all the information I’ve previously tracked if that is the case.

Any tips or insight to this would be greatly appreciated! Thanks!
