Actually this question ( Does DMCA cover apps? ) does not cover my answer. Actually I have made an android app which is published on play store. I had trained some machine learning models which I used in my app and they were present in my apk. Recently I realized that some developer from China has decompiled my apk and used my machine learning models in their app. But cleverly they modified my models content with some fake data, and on runtime they put the right data within the model to make them work. I cannot access the right data to make the model work because it is encrypted in c++ files.
I am wondering is there any way I can file DMCA take down notice against the developer. Or it is considered the "Fair use" in terms of DMCA ( I am new to this act ). Please help me.
