What Happens When You Send a Message
When you send a message in Mind Prism:
Your Device → Our Server → OpenRouter → AI Model
↓
(No message content stored)- Your message travels through our server to OpenRouter
- OpenRouter routes it to the appropriate AI model (GPT, Claude, etc.)
- The response comes back the same way
- We do not store the content of your messages on our servers
Third-Party Data Processing
Your messages are processed by:
- OpenRouter.ai — Routes requests to AI providers
- AI Model Providers — OpenAI, Anthropic, Google, etc.
Each provider has their own privacy policy. Key points:
- Most providers may use your data to improve their models (check their policies)
- Some providers offer data opt-out options
Images and Attachments
When you attach images to messages:
- Images are resized based on your quality setting (SD/HD/UHD)
- Images are transmitted to AI models that support vision
- Images are cached locally on your device (up to 50MB)
- Images are NOT permanently stored on our servers
To clear image cache:

- Delete individual chats containing images
App Preferences
Your preferences are stored locally on your device:
