I don't think it does. Its pretty limited.
You can sync it with your built-in calendar on Android.... it's how I do it and it works well.

Dear User,
We offered zoho.com personal mailbox creation earlier. However, due to a policy change, new users will be able to create a Personal mailbox with the zohomail.com domain only.
Existing customers will have @zohomail.com address added as an alias to the existing zoho.com account.
Hope this helps. Please feel free to write to support(at)zohomail(dot)com for any help.

What about database related app. 3 big name are Notion.so, airtable.com and Zoho Creator
Notion is a database with an "evernote" look and feel, and you can link data (ie pages) together.
Airtable is also a database with a "google sheet" / "microsoft excel" look and feel. But the "cells" can do more than only hosting text and numbers.
Zoho Creator is also a database with a "form" look and feel.
They all have free tiers you can try.
You can do a data backup and pay the $15 or $20 (I forgot) for additional backups above the two that you get per month.
Structure the reports such that there are three or four separate reports to extract the data and reassemble it through Excel.
Other API based exports like Skyvia.com hit the API which has its own limits.
