I have no idea TBH but I suspect your data is safe.
Just to be sure you could copy your table/s into a Google Sheet (using "Copy Data to New Source) and use that as your data source (just for your reference you can select all the data in the database and copy/paste if needed).
Then add a Bot in your app to add data to the database when a row is added/changed in the spreadsheet so you can continue to try the database while having your data safe and sound in a Sheet.
(For my current requirements I prefer the database over a Sheet just for the ease of creating new views)
