I don't understand your syntax:

    `You+App --Read/Write-> f_private(your_data) <--Write only- 3p`

Does this mean a server where third parties can send code to run on your data, but cannot respond to them?

[itissid]

It means any 3rd party even the app provider cannot read your data or the output of the function run. They can provide some data/resources like say map tiles, PoI data and a function to run.

They mean 3rd parties have wo permission instead of rwo to your data store
