Frequently Asked Questions

Is my data really private?
Yes. Every interaction on Lumi happens 100% on your device. We literally can't see your data because it never leaves your phone to go to any cloud server.
Does it require an account?
No account or personal info required. You can start tracking and chatting immediately using Sign in with Apple or skip entirely.
How much does Lumi cost?
Lumi's core features—mood tracking, journaling, and basic AI chat—are free. Premium ($9.99/mo) unlocks unlimited AI, HealthKit insights, and an ad-free experience.
What happens if I switch or upgrade my iPhone?
You can transfer everything by exporting a secure backup. Because your privacy is paramount, every backup is sealed with a unique, one-time private key generated on the spot. You simply use that key to unlock and 'clone' your data onto your new device—ensuring no one but you can ever access your files.
