Question 1

What can I do with LUME?

Accepted Answer

LUME is four security apps in one — all unlocked by your face, with no master password. The MFA Authenticator generates TOTP codes for any service that supports 2FA. Secure Chat gives you post-quantum end-to-end encrypted messaging where contacts are verified by their face-derived keys. The Password Manager stores your logins in a face-locked vault — no master password, ever. Secure Notes keeps sensitive information like API keys, seed phrases, and private documents encrypted at rest. Every feature shares the same zero-knowledge, post-quantum foundation.

Question 2

Is my face data stored anywhere?

Accepted Answer

No. LUME never stores your biometric data. Your face scan generates a cryptographic key on-device in real time — the key is used immediately and then discarded. Nothing about your face is ever transmitted or saved to any server.

Question 3

Can LUME read my data?

Accepted Answer

No. We have no ability to read your passwords, messages, or notes. This is zero-knowledge architecture: the server is mathematically blind to your content.

Question 4

What happens if someone steals my phone?

Accepted Answer

Every feature in LUME requires a live face scan to unlock. Even with full physical access to your device, an attacker cannot open your codes, messages, passwords, or notes without your face. There is no PIN fallback, no master password, and no bypass.

Question 5

What is post-quantum encryption and why does it matter?

Accepted Answer

Post-quantum encryption uses algorithms designed to resist attacks from both today's classical computers and future quantum computers. LUME uses ML-KEM and ML-DSA — algorithms standardized by NIST under FIPS 203 and 204 — so your data remains protected even as computing power advances dramatically over the coming decades.

Question 6

What happens if I lose my phone or switch to a new one?

Accepted Answer

LUME creates an encrypted backup of your vault that only your face can unlock. When setting up on a new device, your face scan re-derives the cryptographic key to restore your data. Your backup is securely stored so switching devices is seamless — no passwords to remember, no codes to transfer manually.

Question 7

How do I delete my account?

Accepted Answer

Account deletion must be done from within the LUME app. Go to Settings → Account → Delete Account and follow the prompts. Once deleted, all data — including encrypted backups — is permanently and irreversibly removed. Because LUME is zero-knowledge, we have no ability to access or restore your data on your behalf.
