Can I host an app in a clients account and restrict their access to its backend

[Gerald_Kariuki]

Hi Guys,
After several months working on an app I’m now faced with an unexpected deployment problem.
How can I set up Appsheet to access data using the credentials of signed in user while denying access to the author account i.e. restricting access to the data from the backend.

I want to present my app to several clients each with a unique data set/sheet.
This has meant that I have to create several copies of the app one for each client.
My options as I see them…

1. create an appsheet account with the clients email and host the app there… Problem is that they now have access to the app backend and may well copy and use the app without further reference to me…(I intend to charge on a subscription basis.)
2. Retain the app in my account… This means that I now have access to the clients data from the backend which presents a liability of responsibility (some of the targeted clients are competitors).
3. Setting Access Mode to “as a user” is unhelpful because it would require that all users have access to the data files which is undesirable.

I hope Appsheet can provide for authors who want to retain access to the app backend without unrestricted access to client data…

I’ll appreciate any thoughts on this…
Thanks for reading through…
