Need a hand?

Email support@lumi.app and a person answers. There is no chatbot in front of it.

What we can help with

• Getting back in. A sign-in that will not work, a lost device, a passkey that has stopped being recognised.
• Your data. A copy of everything, or deleting it. Both are in the app under Privacy, and we can walk you through either.
• Billing. Anything about a subscription, a trial, or a refund.
• Something that looks wrong. A number that does not match what you logged, a screen that will not load.

What we cannot do, and why

We cannot read your health logs or your conversations with Lumi. No support tool exposes them, because no such path exists in the system — it is blocked in the architecture, not by policy. So if you write to us about an entry, describe it rather than asking us to look: we genuinely cannot.

We also cannot recover an anonymous-mode device. There is no account, no email and no server-side record of you, which is the point of it — and it means a lost phone is a lost journal. The app says this before you choose that mode.

Security

Found something? Write to security@lumi.app. Tell us what you found and how to reproduce it; we will confirm we received it, and we will not take action against anyone reporting in good faith.

If your account is on hold

Email support and a person will answer. Holds can be lifted, and your entries are not deleted while one is in place.
