Apps in production and anyone with sensitive data.

Which plan to pickThe app is free, so the only decision is whether the privacy trade-off is acceptable for what you're asking. If you need the model inside your own software, have a developer use the API or run the open model through a provider that keeps your data in Australia.Stay on Free unless you also want a VPN. Plus is good value if you'd pay for a VPN anyway. Pro is $19.99, the same as ChatGPT Plus or Claude Pro, so only pick it if anonymity matters more to you than features.Start free. If you're putting anything sensitive in or building something people will use, switch to a paid API key so your prompts aren't used for training. Google AI Pro only makes sense if you'd use the Gemini app upgrade too.
