With Sleep Cycle’s lab-grade tracking, Luma uses your tracked nights to understand your routines and habits. Chat with Luma to get insights and personalized advice to help you build healthy habits that improve your sleep and well-being.

Luma is available in the Sleep Cycle App version 6.25.47 on iOS for new users. If you’re an existing user, Luma will be available to you in 2026.

Having a general conversation with Luma is available on both Premium and Free. If you would like to chat about your own sleep and receive tailored insights, you’ll need to be on Premium.

Luma is built with Sleep Cycle’s strict data protection framework, treating all sleep-related information as health data, applying the highest level of security.

Luma uses AI models (including OpenAI technology) to generate tailored insights, but your identifiable sleep data never leaves Sleep Cycle’s secure systems. All shared data is anonymized, limited to what’s necessary, and processed under strict privacy protections.

It’s your choice if you wish to share personal information in free-text conversions.
