1. Built-in Local AI Model (Chat LLM Only)

Chat LLM includes an optional built-in local AI model that runs entirely on your device. When using the local model:

• All conversations remain on your device
• No data is transmitted to any external servers
• The app can function offline
• No account or API key is required
• Prompts and responses are stored locally on your device only

We do not have access to any conversations you have with the local model. This feature is only available in Chat LLM. LLM Pro operates exclusively using cloud-based services.

2. Free Cloud AI Access

Both Chat LLM and LLM Pro provide free cloud AI access without requiring an API key. When using free cloud AI:

• Your text prompts are sent to our backend server
• Requests are forwarded to the AI provider
• Responses are returned to your device
• No account or API key is required

We do not store your prompts or responses. Messages are processed in real time and discarded after delivery. Free cloud access is text-only and does not support image or document uploads.

3. Premium Subscription (LLM Pro Only)

LLM Pro offers a premium subscription (£9.99 per month) that unlocks additional AI features. When using premium subscription features:

• Your prompts and image requests are sent to supported AI providers
• Requests may pass through our backend server where required
• Responses and generated images are returned to your device
• Some models may retrieve up-to-date information via web search
• Subscriptions are managed entirely through Apple’s App Store

We do not store prompts, responses, or generated images. All processing is performed in real time and data is discarded after delivery.

4. AI Image Generation (LLM Pro Only)

LLM Pro includes built-in AI image generation and image-to-image editing. Image generation is provided via third-party AI services, including Replicate. When using image generation:

• Text prompts and optional source images are transmitted to Replicate or other supported providers
• Generated images are returned directly to your device
• Image usage limits are enforced and displayed in-app

We do not store image prompts or generated images on our servers.

5. Voice Chat (Optional Feature)

Both Chat LLM and LLM Pro optionally support real-time voice conversations using third-party providers. This feature requires you to supply your own compatible API key (such as xAI). When using voice chat:

• Your voice input is transmitted directly to the selected provider
• Audio is processed in real time for speech recognition and response generation
• Conversation transcripts may be stored locally on your device
• Your API keys are stored only on your device

Neither app stores voice data or transcripts on our servers.

6. Bring Your Own API Key (Advanced Option)

Both apps allow you to connect your own API keys to access additional third-party AI services. If you choose to use this feature:

• Content is transmitted directly from your device to the selected provider
• Prompts, images, documents, and voice data are handled by that provider
• API keys are stored only on your device

We do not receive, store, or log content sent using your own API keys.

7. How Your Data Is Used

Neither Chat LLM nor LLM Pro creates user accounts, tracks usage, or collects analytics. We do not sell or share user data with advertisers.

Neither app does the following:

• Store prompts, images, documents, or voice data on our servers
• Store API keys on our servers
• Track users across apps or websites
• Include advertising or analytics SDKs

8. Third-Party Data Handling

While we do not retain your content, third-party AI providers may process or retain data according to their own privacy policies:

• Groq: https://groq.com/privacy-policy/
• Replicate: https://replicate.com/privacy
• xAI: https://x.ai/legal/privacy-policy/
• OpenRouter: https://openrouter.ai/privacy
• OpenAI: https://openai.com/policies/row-privacy-policy/

9. Security

All network communication uses secure HTTPS connections. Local data remains on your device unless transmitted to a selected AI provider.

10. Your Rights

Because we do not store personal data on our servers, there is no user data held by us to access, export, or delete.

11. Subscription Management

LLM Pro subscriptions are managed entirely through Apple’s App Store. We do not process or store payment information.
