Gemini 2.0 Flash Unpaid Services

Hello Gemini,

I want to use Gemini 2.0 Flash model and “You aren’t billed for the usage of experimental Google models”.
For unpaid services, Gemini will collect my data, this is not what I expected.
I do not want Gemini collect my data. What should I do?

Thanks a lot !

Any one can help me ?
