How to delete the local cache while maintaining the synced data on the cloud? Is it possible to have it all stored on the cloud?

Hi I know this app prioritises offline usage and stores data locally in the browser.

But is there a way to find the saved data and delete it from the device and keep the data on the cloud when subscribed to the syncing service?

I just worry that it might take up a lot of space if I use it intensively.

I am using Macbook.

Thank you very much in advance.
