Blynk android app

Hi all.
I have an project with blynk application and it was built successfully both hardware and software, it delivered to my customer already. But a problem occur, when client use the Blynl app on android phone, they can setup any parameter of this project that can be make the project work wrong. So i want to ask is there any way to keep only me can adjust app’s paramester on android phone, my customer can not ?

Thanks and best regard,

As you’re apparently using this as a commercial application, you should be contacting the guys at Blynk.io for support, to get the most out of your pricing plan.

Hi,

There is only one way to do so is by having a paid subscription from Blynk.
