Noctura Privacy Policy
Last updated: October 27, 2026
Noctura is a sleep coaching app made by NeuraWell Inc. This policy explains what we collect, why, and the choices you have. Noctura is coaching, not medical care, and it is not a substitute for a doctor.
What we collect
- Account: your email address, name, and a password (stored only as a one-way hash).
- Sleep diary: the bedtimes, wake times, awakenings, quality ratings, naps and notes you log.
- Intake and profile: answers you give about your sleep history, conditions, medications and goals.
- Coach conversations: the messages you exchange with the coach.
- Health and Apple Watch data (optional): if you grant access, sleep stages, heart rate and movement from Apple Health and the Noctura watch app, used only to pre-fill your sleep diary and improve your coaching. We never use Health data for advertising or sell it to anyone.
- Usage data and session recordings: which features you use, basic device information, and recordings of how the app's screens are used. We use these to fix bugs and improve the app.
- Push token: so we can send your daily check-in reminder, if you turn notifications on.
How we use it
- To run the program: track your progress, set your sleep window, and let the coach respond with your history in context.
- To send reminders you asked for.
- To understand how the app is used, in aggregate, and to fix problems.
We do not sell your data, and we do not use it for advertising.
Who processes it
- Supabase stores your account and data in a database in the United States.
- Fly.io runs the Noctura server.
- OpenRouter and the language-model providers it routes to generate coach replies. Your coach messages, diary summary and profile are sent to them for that purpose only.
- PostHog receives usage events and session recordings tied to a user id.
- Apple delivers push notifications.
Your choices
- Health access can be granted or revoked any time in iOS Settings; the app works without it.
- Notifications can be turned off in the app or in iOS Settings.
- Delete your account from Settings in the app. This permanently removes your account, diary, conversations and profile from our systems.
- Email us to request a copy of your data or ask a question.
Retention and security
We keep your data while your account exists and delete it when you delete your account. Data is encrypted in transit, and access to the database is restricted to your own account through row-level security.
Children
Noctura is not intended for anyone under 18.
