Some data not showing – Diary, Journal, Notes - Diaro Review

I added daily routine data. Just now I saw that from 28th November to 12th December data is not showing. Just 9th December data is available. How can I trust in future on this app. If possible, please check and recover my important data from 1st December to 12th December.
