## Data policy
Requests to this model are sent to Google AI Studio, whose API terms govern how they handle your data: [Google AI Studio data policy](https://ai.google.dev/gemini-api/terms). Clonvo doesn’t store prompts or responses unless your organization turns on retention.
## Bring your own key
From Pay as you go up, a Google AI Studio key added under Provider keys is used for this model before your credits: $25,000 a month free, then 4% of list price. [How bring-your-own-key works](https://clonvo.com/docs/byok.md).
