The solution

Six areas of life, one single intelligence

Active listening, mood journaling, gentle CBT micro-actions. No judgement.

Goals, priorities, focus. Direct, factual, zero fluff.

Sleep, energy, cycle. It reads your health, never diagnoses.

Follow-ups, key dates, non-violent communication. Your people matter.

Awareness over maximisation. Manual entry, zero open banking.

Ideas, writing, unblocking. Regular output over perfection.

On-device inference: the language model runs on your iPhone chip. No request ever hits a server.

Encrypted at rest: entries, audio and photos are sealed with the Secure Enclave.

Zero account, zero server: no signup, no password to trust. LUNA has no backend to leak.

Zero third-party analytics: no Firebase, no Mixpanel, no pixel. Verifiable in the code.
