These Terms of Service (the "Terms") govern your access to and use of the D1Sleep website, applications, and related services (collectively, the "Services"). By accessing or using the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services.
These Terms are between you and the operator(s) of the Services ("D1Sleep," "we," "us," or "our").
You must be at least 13 years old (or the minimum age required by applicable law) to use the Services. By using the Services, you represent that you meet this requirement.
D1Sleep allows you to import, store, and view sleep-related data from supported sources (such as wearable providers and health platforms) and from manual inputs. The Services are provided for personal, non-commercial use.
The Services are currently provided free of charge. We do not offer subscriptions or payments through the Services.
We may modify, suspend, or discontinue any part of the Services at any time, including features, availability, or supported integrations, without liability to you.
THE SERVICES ARE PROVIDED FOR INFORMATIONAL AND WELLNESS PURPOSES ONLY. D1SLEEP IS NOT A MEDICAL DEVICE AND IS NOT INTENDED TO DIAGNOSE, TREAT, CURE, OR PREVENT ANY DISEASE OR HEALTH CONDITION.
Data imported from wearables and platforms may be inaccurate, incomplete, delayed, or inconsistent across devices. Any insights, trends, or summaries are estimates and are not medical advice. You are solely responsible for your health decisions and for consulting qualified professionals when appropriate.
Do not use the Services for emergency situations. If you believe you may have a medical emergency, seek immediate medical attention.
You may need an account to use certain features. You agree to provide accurate information and to keep your account information current. You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account.
We are not responsible for any loss or damage arising from unauthorized use of your account. You should use a strong password and take reasonable steps to secure your account and devices.
The Services may support connections to third-party devices and platforms (for example, wearable providers and health platforms). When you connect an integration, you authorize us to access and import the data you permit through that third party's authorization flow.
Third-party services are not under our control. We do not guarantee their availability, accuracy, or compatibility, and we are not responsible for third-party acts or omissions, including how they handle your information. Your use of third-party services is governed by their terms and policies.
You retain any rights you may have in the data you upload, import, or enter into the Services (including sleep and wellness-related information) ("User Data").
You grant D1Sleep a limited, worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, and display your User Data solely to operate and provide the Services to you (including generating on-site summaries and insights).
You are responsible for your User Data, including its legality and accuracy, and for maintaining your own backups. We do not guarantee that any User Data will be recoverable or retained, and we are not liable for loss of User Data to the maximum extent permitted by law.
You agree not to misuse the Services. You will not, and will not attempt to:
We may suspend or terminate access if we believe you have violated these Terms or pose a risk to the Services or others.
The Services, including software, text, graphics, design, and all related intellectual property, are owned by us or our licensors and are protected by applicable laws. Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable license to access and use the Services for your personal, non-commercial use.
You may not copy, modify, distribute, sell, lease, or create derivative works from the Services except as expressly permitted by these Terms.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
We do not warrant that the Services will be uninterrupted, timely, secure, error-free, or that any data, metrics, or insights will be accurate or reliable.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL D1SLEEP BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, USE, OR GOODWILL, ARISING OUT OF OR RELATED TO YOUR USE OF (OR INABILITY TO USE) THE SERVICES.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, D1SLEEP'S TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICES WILL NOT EXCEED $100 USD.
Some jurisdictions do not allow certain limitations of liability, so some of the above limitations may not apply to you.
To the maximum extent permitted by law, you agree to defend, indemnify, and hold harmless D1Sleep from and against any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Services; (b) your User Data; or (c) your violation of these Terms or applicable law.
You may stop using the Services at any time. We may suspend or terminate your access to the Services at any time, with or without notice, for any reason, including if we believe you violated these Terms, or if we discontinue the Services.
Upon termination, the license granted to you under these Terms ends. Sections that by their nature should survive will survive, including disclaimers, limitation of liability, and indemnification.
These Terms are governed by the laws of the jurisdiction where the operator of the Services is located, without regard to conflict of laws principles.
To the extent permitted by law, you agree that any dispute arising out of or related to these Terms or the Services will be brought on an individual basis and not as a plaintiff or class member in any purported class, collective, representative, or private attorney general proceeding.
To the extent permitted by law, you agree to exclusive jurisdiction and venue in the courts located where the operator of the Services is located for any dispute not subject to mandatory arbitration under applicable law (if any).
