Your conversations stay yours
We built lm9 LLM for people who do not want their words mined, stored indefinitely, or fed back into someone else’s model.
- We never train on your data. Your prompts and replies are not used to train our models—or anyone else’s—now or in the future.
- We do not keep your chats on our servers. Conversation content is processed to give you a response, not archived as a permanent record on lm9 systems.
- Delete a chat, and it is gone forever. When you remove a conversation, it is not recoverable. There is no hidden copy waiting to be sold or scraped later.
Account and billing details (email, plan, token usage) are handled separately for running the service. See our Privacy Policy for what we collect outside of chat content.
