Do I need an API key?

For online/cloud models, yes — bring your own key from the provider you choose in Settings (BYOK). For on-device models, no key is required after you download a model.

Where are my API keys stored?

On iOS they live in the Keychain. On the web companion they live in your browser’s localStorage. They are never sold and are not used by us to call models on your behalf without your configuration.

Can I use Chat Blues offline?

Yes. Open Settings → On-Device AI, download a model (Wi‑Fi recommended), load it, and chat without sending prompts to the cloud.

How do Sign in with Apple / Google work?

Sign-in is optional. It enables chat history sync across devices via Firebase. You can use the app without an account for local and on-device features.

How do I delete my account?

In the app: open Settings → Account → Delete account. This permanently removes your synced chats and messages, your settings, your stored API keys and your uploaded attachments from our servers, and then deletes the sign-in account itself. You can also delete individual chats at any time.

If you would rather we did it for you, email officialvishwateja@proton.me from the address associated with your account.

Why does the app ask for microphone / camera / photos?

Microphone and speech recognition are for voice input. Camera and photo library are only used when you choose to attach or save images. Local network is only for optional self-hosted AI on your LAN.

What iOS version is required?

Chat Blues requires iOS 17.0 or later, and runs on both iPhone and iPad.
