It's like with Gemini and Google smart devices. You need to opt-in for data training to use Gemini apps. This means you won't be able to access basic features like asking Gemini to turn off your smart light bulbs. Essentially, Google is preventing you from using any smart features unless you allow data training on your own. Even to access basic features like chat history, you need to enable Gemini activity. This essentially allows Google to train on all of your conversations. This is even for paid tiers
