Google's Gemini terms have some important nuances:
Consumer Gemini (free/Gemini Advanced):
- Google's ToS says "you retain your intellectual property rights in your content"
- But: Google takes a broad license to use your inputs/outputs for service improvement and training
- Commercial use of outputs is technically permitted but not explicitly guaranteed
Gemini API (Vertex AI / Google AI Studio):
- Much stronger protections: Google commits to not using API customer data for model training (for paid tier)
- You retain all rights to outputs
- Explicit commercial use permitted
- Enterprise agreements offer additional IP indemnification
For your SaaS product, the API terms are the relevant ones. Your users' rights flow through your product's ToS, not directly from Google.
