Security of a trained tflite model

I was wondering how secure is the deployment of a tensorflow-trained .tflite model inside an Android application? Is it possible for someone to extract my trained model and use it directly inside their own app? I'm aware that they can't recover my training dataset from the model, but theoretically they could extract my model, train it with additional samples and improve the performance of the model, without having my original training dataset.

Are there some safety mechanisms to prevent this? Other then running the inference in the cloud?
