Terms of Use

Nightmark is provided by Baseframe Labs, an independent studio operated by Abhi Yoheswaran. It is a general-wellness app for understanding existing Apple Health sleep records, reviewing patterns and interpreting suggested bedtimes. It includes iPhone and iPad interfaces, widgets and an Apple Watch companion.

These terms explain the app’s use and limitations. The Nightmark Privacy Policy explains how information is handled. For help, contact support@baseframelabs.com.

The App Store version of Nightmark uses Apple’s Standard Licensed Application End User License Agreement (Standard EULA). Your licence is granted by the application provider identified in the App Store, under that agreement. These pages provide app-specific information and do not replace the Standard EULA or create a custom EULA. If these terms conflict with the Standard EULA about the app licence, the Standard EULA controls, subject to mandatory law.

The app is licensed for use, rather than sold. The Standard EULA sets out the permitted use on Apple devices you own or control, applicable usage rules, restrictions and termination. Ownership of Nightmark’s software, design and branding stays with its respective rights holders. Using Nightmark does not transfer those rights to you or transfer ownership of your own information to us.

Contact Baseframe Labs for Nightmark support. Apple does not provide customer support or maintenance for Nightmark.

You need a compatible Apple device and operating system. Check the current App Store listing for compatibility. A supported recording source must already have supplied sleep records to Apple Health. Nightmark reads those records with your permission; it does not create or modify Apple Health records.

Sleep stages and other measurements depend on your hardware, recording source, permissions and available history. Missing or delayed records can limit summaries and recommendations. Nightmark cannot guarantee that a recording source is complete or accurate, or that every feature or measurement is available on every device.

Sleep ratings, observations, sleep debt, suggested bedtimes, typical ranges and travel adjustments are estimates for general wellness. They depend on available records and the app’s calculations. They may change as more records become available or the app is updated.

These outputs are not clinical measurements, diagnoses or treatment, and they do not guarantee improved sleep or any other outcome. An association between sleep and another measurement does not establish causation.

Use Nightmark as one source of general information about your habits. It is not a substitute for professional medical advice or care. If you have concerns about sleep, symptoms or a health condition, speak with a qualified health professional. Do not delay care or change treatment based only on an app estimate.

Notifications are optional reminders. Device settings and system behavior can affect delivery, so do not rely on them for medical or other time-critical needs. Review your lock-screen settings before enabling personal notification details.

Use the app lawfully and respect other people’s privacy and rights when sharing information.

You decide whether to share a sleep summary and where to send it. Review the preview before sharing, including whether the optional sleep-stage graphic is included. The summary excludes heart rate and HRV. A recipient or external service may retain or forward what you send.

Apple Health, the App Store, device backups and external apps operate under their own terms and settings. Their availability and practices are outside Baseframe Labs’ control. Our Privacy Policy explains the distinction between local app processing, Apple services and voluntary support email.

Nightmark version 1.0 is launching free worldwide for iPhone, iPad and Apple Watch. The current app grants early-adopter access without a purchase flow. It does not offer a paid subscription or trial.

This describes the current offering. It does not promise that every future version or service will remain free. Any future paid offering would need its own clear price and purchase terms before you choose to buy it.

We may update Nightmark to fix issues, change calculations or features, or support changes to Apple platforms. Compatibility and availability may change, and we do not promise uninterrupted availability or support for every device forever.

You can stop using the app at any time. The Standard EULA governs licence termination. For the effects of clearing the cache, removing the app or changing permissions, see the privacy controls and deletion explanation.

Nothing on this page excludes or limits consumer rights or protections that cannot lawfully be excluded or limited. Any warranty or liability provisions in the Standard EULA apply only to the extent permitted by applicable law. Mandatory protections available where you live continue to apply.

We may revise this page as the app or its terms change. We will publish the revision here, update the effective date and describe material changes. Any additional notice or agreement required by applicable law will still be required.
