Privacy Policy

1. Information We Collect

A. Information You Provide

We may collect:

• Email address and name, if you choose to sign in with Apple or Google, or if you contact us. SleepQ can be used without signing in at all, in which case we hold no email address for you.
• Your sleep goal, usual bedtime and wake time, and similar preferences you set in the app
• The evening check-in details you choose to log, such as caffeine, alcohol, stress, exercise, and late meals
• Messages you send to the AI Sleep Coach
• Feedback or support messages you send us

B. Health Data (Apple Health and Health Connect)

SleepQ reads health data from your device's health platform — Apple Health on iPhone, and Health Connect on Android — and only with your explicit permission. On both platforms SleepQ requests read-only access. It never writes, modifies, or deletes anything in Apple Health or Health Connect.

With your permission, SleepQ reads:

• Sleep sessions, including time in bed, sleep duration, and sleep stages (light, deep, REM, and awake periods)
• Heart rate, and resting heart rate on iPhone
• Heart rate variability
• Respiratory rate
• Blood oxygen saturation

SleepQ reads these types only for periods relevant to your sleep, and only the types you have authorized. Denying or revoking any of them does not stop you from using the app — it just means insights that rely on that metric are unavailable.

Health data:

• Is used solely to provide the sleep scores, insights, coaching, and experiments you see in the app
• Is not used for advertising or marketing
• Is not sold to third parties
• Is not shared with data brokers

To deliver these features, SleepQ transmits the sleep metrics described above — and metrics derived from them, such as sleep efficiency and how long you took to fall asleep — to our servers over an encrypted connection, and to the AI providers described in Section 3. Section 4 describes everyone we share information with.

C. Health Connect (Android)

On Android, SleepQ integrates with Health Connect and handles the data it receives as described in this policy. Specifically, data read through Health Connect:

• Is accessed only after you grant each permission in Health Connect, and only for the data types listed above
• Is used only to generate the sleep scores, insights, coaching, and experiment results shown to you in the app
• Is stored on our servers in the United States, in the form of the sleep metrics described above
• Is shared only with the AI providers named in Section 3 and the infrastructure providers named in Section 4, never with advertisers or data brokers, and never sold
• Is deleted when you delete your account, as described in Section 5

SleepQ does not use Health Connect data to serve or personalize advertising, and does not transfer it to any third party for advertising purposes.

You can review or revoke SleepQ's Health Connect permissions at any time in the Health Connect app, or through Settings → Security & privacy → Privacy → Health Connect on your Android device. On iPhone, you can revoke Apple Health permissions at any time in Settings → Health → Data Access & Devices. Revoking access stops SleepQ from reading any further data; to remove data we have already received, delete your account (see Section 5).

D. Automatically Collected Information

We may collect limited technical information such as:

• Device type
• Operating system version
• App version
• Anonymous usage analytics
• Crash diagnostics

This information helps us improve app stability and performance.

2. How We Use Your Information

We use your information to:

• Analyze your sleep patterns using artificial intelligence
• Generate personalized sleep insights and reports
• Improve our sleep scoring models
• Provide customer support
• Improve app functionality and performance
• Communicate important updates (if you opt in)

We do not sell your personal or health data.

3. AI-Powered Sleep Analysis

SleepQ uses third-party artificial intelligence services to analyze your sleep data and generate personalized insights, summaries, and recommendations. We want to be transparent about how this works.

A. AI Service Providers

To generate AI-powered insights, SleepQ sends sleep-related data read from Apple Health or Health Connect to the following third-party AI providers:

• OpenAI (OpenAI, L.L.C.) — used to generate sleep insights, summaries, and recommendations through its API
• xAI (X.AI Corp., operator of the Grok models) — used to generate sleep insights, summaries, and recommendations through its API

We may route requests to one or more of these providers depending on availability, performance, or the type of analysis requested.

B. What Data Is Sent

When you request or receive AI-generated insights, we may transmit:

• Sleep duration, time in bed, and sleep stages
• Heart rate, heart rate variability, respiratory rate, and blood oxygen saturation associated with sleep periods
• Metrics derived from the above, such as sleep efficiency and time taken to fall asleep
• Any other sleep-related metrics you have authorized through Apple Health or Health Connect
• Aggregated trends derived from your historical sleep data
• The check-in details you choose to log, such as caffeine, alcohol, stress, exercise, and late meals

We do not send your name, email address, Apple Health or Health Connect identifiers, or other directly identifying information to these AI providers along with your sleep data. Data is transmitted over encrypted connections (HTTPS/TLS).

C. How Providers Handle Your Data

We use the commercial APIs of OpenAI and xAI under their standard API terms, which include the following protections:

• No training on your data. OpenAI and xAI state that data submitted through their APIs is not used to train their models by default.
• Limited retention. API providers may temporarily retain submitted data for abuse monitoring and safety review (typically up to 30 days for OpenAI), after which it is deleted. xAI's retention practices are governed by its API terms.
• No advertising use. Data sent to these providers is not used for advertising or marketing.

Your data is governed by each provider's privacy practices while in their possession. You can review them here:

• OpenAI: https://openai.com/policies/privacy-policy
• xAI: https://x.ai/legal/privacy-policy

D. Automated Decision-Making

The insights, scores, and recommendations generated by SleepQ are produced by AI models and are intended as informational guidance only. They are not medical advice, diagnosis, or treatment, and SleepQ is not a medical device. AI-generated content may contain inaccuracies. Always consult a qualified healthcare professional for medical concerns.

E. Your Choices

You can:

• Decline Apple Health or Health Connect permissions, which prevents any health data from being read or sent to AI providers
• Revoke those permissions at any time — in Settings → Health → Data Access & Devices on iPhone, or in the Health Connect app on Android
• Delete your account from within the app, or contact us to request deletion of your data

4. How We Share Information

In addition to the AI providers described in Section 3, we may share limited information with:

• Service providers that help operate our infrastructure (e.g., cloud hosting or analytics providers)
• Legal authorities if required by law
• A successor entity in the event of a merger or acquisition

We do not share health data for advertising or marketing purposes.

5. Data Retention

We retain personal and health data only as long as necessary to:

• Provide the Service
• Comply with legal obligations
• Resolve disputes
• Enforce our agreements

If you request deletion of your account, we will delete your personal data and the health data we have received from Apple Health or Health Connect within a reasonable timeframe, except where retention is required by law. Deleting your account does not affect the data held on your own device by Apple Health or Health Connect — SleepQ only ever had read access, and only deletes the copy we hold. Data temporarily held by AI providers (Section 3) is subject to their respective deletion practices. See Delete Your Account for step-by-step instructions.

6. Your Rights

As a U.S.-based user, you may:

• Request access to your personal data
• Request correction of inaccurate data
• Request deletion of your data
• Withdraw consent for health data access
• Withdraw consent for AI-powered analysis (note: this may disable insight features)

Please contact us at support@sleepq.app.

You may also revoke health data access directly on your device at any time — through Apple Health on iPhone, or Health Connect on Android.

7. Children's Privacy

SleepQ is not intended for children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, please contact us and we will delete it.

8. Analytics Services

We may use third-party analytics tools to understand general usage patterns and improve the app. These tools collect anonymized or aggregated technical data. Health data read from Apple Health or Health Connect is never shared with analytics or advertising providers.

9. Data Security

We use reasonable administrative, technical, and physical safeguards to protect your information, including:

• Encrypted data transmission (HTTPS/TLS) to all servers, including AI providers
• Secure cloud hosting
• Restricted internal access to data

However, no method of transmission or storage is completely secure.

10. U.S. Operations

SleepQ operates and stores data within the United States. The AI providers described in Section 3 (OpenAI and xAI) are U.S.-based companies and process API requests on infrastructure that may include U.S. and other regions, governed by their respective terms. By using the Service, you consent to this processing.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make material changes — including changes to the AI providers we use or how data is shared with them — we will update the "Last Updated" date and may provide notice within the app.
