Privacy Policy & Terms of Service

Lunomia is built around private, on-device sleep analysis. There is no account to create, your sleep data is read from Apple Health and analyzed on your iPhone, and we never see it. This page explains exactly what does and does not leave your device, and the terms for using the app.

The short version: Your sleep and health data is read from Apple Health and analyzed on your device. We never see it and we never sell anything. Lunomia does collect anonymous usage and purchase events, with nothing in them that could identify you, and we use those only to make the app better. One optional feature, the cloud AI engine, sends a summary of a single night to be written up, and only after you switch it on and agree.

Privacy Policy

Lunomia (“we”, “our”, or “us”) is committed to protecting your privacy. This Privacy Policy describes how our app handles user information.

1. What We Never Collect

Lunomia has no accounts and no sign-up. We do not ask for, receive, or store your name, email address, phone number, or any advertising identifier. We cannot work out who you are, and we do not try to. We do not sell data, we do not share it for advertising, and we do not build a profile of you.

2. Your Sleep and Health Data

Lunomia reads sleep-related data from Apple Health with your permission, and only for reading. Your nights, sleep stages, heart rate, breathing and blood oxygen are processed on your device, and every chart, animal and summary you see is calculated there.

This data is not uploaded to us. The single exception is the optional cloud AI engine described in section 4, which you have to turn on yourself.

You are always in control:

Apple Health decides what Lunomia may read. You can change or revoke it any time in the Health app.
Removing the app removes the copy of your sleep analysis held on your device.
Your original health data belongs to Apple Health, not to Lunomia, and stays there.

3. Anonymous Usage and Purchase Events

To know which parts of Lunomia are worth improving, the app reports anonymous events: that a screen was opened, that a chart was read, that a purchase or a subscription renewal went through. This is how we find out that a feature is confusing or that a screen is quietly broken.

These events are deliberately thin:

They carry no name, email address, or account, because none of those exist.
They never contain your sleep, health, or personal data, and never the text of an AI summary.
They cannot be traced back to you by us or by anyone else.

We use them for one purpose only, which is understanding how Lunomia is used so we can make it a better product. They are never sold, never shared with advertisers, and never used to target you.

4. The Optional Cloud AI Engine

Lunomia's written summaries, such as Sleep Recap and trend insights, are normally generated by Apple Intelligence on your device. Nothing leaves your iPhone when it works this way, and this is the default wherever your iPhone supports it.

If your iPhone cannot run Apple Intelligence, or you simply prefer it, you can switch on the cloud engine in Settings. Lunomia explains this and asks you to agree before the first reading is generated. You can switch back at any time.

When the cloud engine is on, and only when you ask for a reading:

Lunomia sends a short summary of that one night, such as how long you slept, your sleep stage totals and your bedtime.
It is sent without your name or any account, because there is none to send.
Our server does not store it. It passes the summary to a third-party AI provider, which writes the text and sends it back.
The summary is not written to our logs.

5. Third-Party Services

Lunomia relies on a small number of outside services, each limited to one job: Apple Health, which holds your health data and is governed by Apple's privacy policy; an analytics service that receives the anonymous events in section 3; a payment service that handles subscriptions and restores your purchase on a new device; and, only if you turn on the cloud engine, an AI provider that writes the summary described in section 4. None of them receives anything that identifies you.

6. Children’s Privacy

Lunomia does not knowingly collect any personal information from anyone, including children under 13.

7. Changes to This Policy

We may update this policy from time to time. Changes will be reflected in the app or this page.
