LumiChats is a student-first AI platform designed for educational purposes. This Privacy Policy explains how we collect, use, and protect your information when you use LumiChats, including Chat Mode and Study Mode.
Your privacy is extremely important to us. LumiChats is built so that students can study with confidence, knowing their content is handled responsibly and securely.
We are committed to transparency. This policy outlines exactly what data we collect, how we use it, and your rights regarding your personal information.
We collect only what is necessary to operate the platform and provide you with a seamless learning experience:
Study Mode is designed with maximum privacy in mind. Here's exactly how your uploaded content is handled:
Any PDF or study material you upload is NOT saved to our database permanently. Your textbooks, notes, and study materials remain completely private.
Content is processed in memory temporarily only to generate AI responses to your questions. Once processed, it's immediately discarded.
When your study session ends or you close the browser, all uploaded content is automatically removed from our servers.
Your study material is never reused for training AI models, never shared with third parties, and never accessed by our team or other users.
Your study material is never stored, reused, or shared. Complete privacy guaranteed.
When using Chat Mode with documents, storage works differently to maintain conversation history:
Uploaded files are processed and relevant content may be stored to maintain conversation context across multiple messages. This ensures the AI can reference previous parts of your conversation.
Storage happens with your explicit consent when you choose to upload files to Chat Mode. You control what you upload and can delete conversations at any time.
Stored content is associated only with your account and is never visible to other users, staff, or third parties. Only you can access your chat history.
You are responsible for the content you upload. LumiChats does not claim ownership over user-uploaded materials and respects intellectual property rights.
Your data is used exclusively for the following purposes:
Generate accurate, context-aware answers to your questions using advanced AI models
Keep conversation history and context for seamless multi-turn interactions
Monitor for abuse, prevent unauthorized access, and maintain service integrity
Analyze usage patterns to improve reliability, performance, and user experience

Important: AI responses are generated using third-party AI providers via OpenRouter. Your queries are processed securely and in compliance with their privacy policies.
