How has sleep changed this week?
Sommeil · get_sleep_summary
Night sleep was more consistent across the last four days. The longest stretch increased, while nap count stayed stable.
Names, emails, notes, and raw sessions stay private.
Trust is part of the product
Thoughtful AI starts with clear boundaries.
Your data is not the product
Sommeil does not sell family data or use it for advertising.
AI stays optional
Core predictions work without generative AI. AI explanations are opt-in and use minimized aggregates.
Guidance, not diagnosis
Every estimate is framed with confidence and safety context. Sommeil does not provide medical advice.
