Your chats are stored on your device. If you sign in, they also sync so you can pick them up on another device. If you create an account, we store your sign in details so you can log in.

Lume is free because it shows ads matched by Koah. When an ad is requested, your question and the answer you were shown are sent to Koah to pick a relevant ad. Koah keeps what it receives under its own privacy policy, so this is not zero retention. Ads only appear if you told Lume you are 18 or over.

Your data is never sold. Your messages are never used to train AI models.

Delete any chat from the chat list, or clear all chats in Settings. Delete your account in Settings to remove your sign in details and synced chats.

If this policy changes, the new version will be posted here with a new effective date.
