When user delete spreadsheet add-on, the document properties store added with the add-on continues to remain?

Question

I'm developing Google Sheets Add-on.

I was just wandering that the document properties store is deleted when users uninstall the add-on. GAS don't have Trigger like 'onUninstalled'. If the properties continue to remain, I don't know where I write the program that delete them.

Who knows my problem??

Answer 1

As it was mentioned in a comment, the properties (script, document, user) aren't deleted when the user uninstall the add-on.

You might add a way for users to delete the properties and warn them that the data stored in properties should be deleted before uninstalling the add-on.
