Terms of Use
Last updated: September 8, 2026
1. Acceptance of terms
By creating an account or using the DreamSleep app ("the App"), you agree to these Terms of Use. If you do not agree, please do not use the App.
2. Description of the service
DreamSleep is a mobile application that provides:
- Personalized sleep coaching through an AI-powered Sleep Coach
- Evidence-based sleep practices and exercises
- Sleep protocol tracking and analysis
- Educational content about sleep science
3. Not medical advice
DreamSleep does not provide medical advice, diagnosis, or treatment.
The App offers general wellness information and evidence-based sleep hygiene practices. The AI Sleep Coach provides suggestions based on established sleep science, but it is not a substitute for professional medical advice, diagnosis, or treatment by a qualified healthcare provider.
You must not rely on any information provided by the App as an alternative to medical advice from your doctor or other qualified healthcare professional. If you have a sleep disorder, medical condition, physical limitation, allergy, or other health concern, consult a qualified healthcare professional before following any recommendation or practice suggested by the App.
Do not disregard professional medical advice or delay seeking it because of information provided by the App. If you experience any adverse reaction, discomfort, or injury while following a recommended practice, stop immediately and seek medical attention.
4. Practices and recommendations – your own responsibility
The App may recommend sleep-related practices and behavioral changes, including but not limited to:
- Exposure to natural daylight or sunlight
- Breathing exercises
- Progressive muscle relaxation and physical exercises
- Changes to sleep schedules, bedtime routines, or lifestyle habits
- Dietary or environmental suggestions related to sleep
These recommendations are general in nature and are based on widely established sleep science. They are not tailored to your individual medical history, physical condition, or health circumstances.
By using the App and following any recommended practice, you acknowledge that:
- You are responsible for assessing whether a recommended practice is safe and appropriate for you personally
- The AI Sleep Coach does not have knowledge of your complete medical history, physical conditions, allergies, medications, or individual risk factors
- Recommendations may not be suitable for individuals with certain medical conditions (e.g., photosensitivity, respiratory conditions, musculoskeletal injuries, cardiovascular conditions, or other health issues)
- You should consult a healthcare professional before beginning any new wellness practice if you have any pre-existing health conditions or concerns
Our liability for damage arising from your use of the App or from following any practice, recommendation, or suggestion provided by the App is governed by Section 13 (Liability).
5. Account and eligibility
- You must be at least 16 years old to use the App.
- You are responsible for maintaining the confidentiality of your account credentials.
- You are responsible for all activity that occurs under your account.
- You must provide accurate information when creating your account.
6. Acceptable use
You agree not to:
- Use the App for any unlawful purpose
- Attempt to gain unauthorized access to the App or its systems
- Interfere with or disrupt the App's functionality
- Use the AI Sleep Coach to generate content unrelated to sleep improvement
- Reverse engineer, decompile, or disassemble the App
- Use automated tools to access the App (bots, scrapers, etc.)
7. AI Sleep Coach
The AI Sleep Coach is designed to be a knowledgeable, personalized companion for your sleep improvement journey. Its responses are grounded in established sleep science and informed by your personal sleep profile, goals, and progress — giving you tailored guidance that adapts as you use the app.
To help you get the most out of it, and to be transparent about how it works, please be aware of the following:
- Powered by a third-party AI model: The AI Sleep Coach is powered by a large language model provided by Anthropic (Claude). While we have carefully designed the coaching experience, individual responses are generated in real time by this third-party model. DreamSleep does not author or pre-approve each response and cannot guarantee that every response will be perfectly accurate, complete, or suited to your specific circumstances.
- AI has inherent limitations: Like all AI language models, the Sleep Coach can occasionally produce responses that are imprecise, inconsistent, or — in rare cases — incorrect. Treat its suggestions as a helpful starting point, not as a definitive authority, and use your own judgment when deciding whether a recommendation is right for you.
- Not a substitute for professional advice: The AI Sleep Coach is a wellness tool, not a medical professional. For any health-related concerns, always consult a qualified healthcare provider. See Section 3 for full details.
- Liability for AI-generated content: Responses are generated in real time by a third-party model and are not individually reviewed by us before delivery. We select, configure, and monitor the AI Sleep Coach with due care. Our liability for individual AI responses is governed by Section 13 (Liability); your statutory rights remain unaffected.
- Usage limits: A weekly usage limit applies to chat interactions to ensure service quality for all users.
We are committed to continuously improving the AI Sleep Coach experience and welcome your feedback at support@dreamsleep-app.com.
8. Purchases, subscriptions and payment
Basic use of the App may be offered free of charge, including a time- and usage-limited free trial as described in the App. Paid access is offered as (a) the 8-week coaching program, purchased once at a fixed price and granting access for 8 weeks from the date of purchase without automatic renewal, and (b) optional auto-renewing subscriptions after the program (currently “Premium Lite” and “Premium Pro”). The scope, price and billing period of each offer are shown in the App and in the store before you buy.
- Purchases and subscriptions are made exclusively through the Apple App Store or Google Play. Billing, renewal, cancellation and refunds are handled by the respective store under its own terms. Prices, access periods and conditions are displayed in the store before you confirm a purchase.
- The 8-week coaching program ends automatically 8 weeks after purchase; nothing renews and nothing further is charged. After it ends, your account, your sleep diary and your practices remain available to you; the AI coach chat and other premium features then require a subscription. Subscriptions renew automatically unless cancelled in your store account settings before the end of the current billing period. Deleting the App or your DreamSleep account does not by itself cancel a subscription.
- If you are a consumer, you have a statutory right of withdrawal (Widerrufsrecht) for contracts concerning digital content and digital services. For purchases made through an app store, the withdrawal process is handled by the store operator; the store informs you about the right of withdrawal, its conditions and any expiry (for example when you expressly agree to immediate access to digital content) before the purchase. Our withdrawal notice with the model withdrawal form is available at Right of withdrawal.
- Where we offer promotional or gift codes, the specific conditions communicated with those codes apply. Gift codes currently grant the 8-week coaching program; promotional codes grant a discount on the offer stated with the code. Codes are non-transferable and cannot be exchanged for cash.
- The free trial (currently 3 days and up to 3 AI coach messages) is free of charge, ends automatically and does not create any payment obligation. After the trial ends, continued use of the App requires a purchase unless you already have paid access.
- Price changes for subscriptions apply only to future billing periods. A price increase takes effect only once you have agreed to it through the store; otherwise, the subscription ends at the end of the current billing period. The store informs you of the change in advance.
9. Intellectual property
All content in the App, including but not limited to text, graphics, educational materials, knowledge modules, and software, is the property of DreamSleep and is protected by copyright and other intellectual property laws.
You may not reproduce, distribute, or create derivative works from any content in the App without prior written permission.
10. Data and privacy
Your use of the App is also governed by our Privacy Policy, which describes how we collect, use, and protect your personal data.
11. Account termination
You may delete your account at any time through the App's Settings or by contacting us at support@dreamsleep-app.com. See our account deletion page for details.
We reserve the right to suspend or terminate accounts that violate these Terms. Where reasonable, we will warn you before doing so; in cases of serious violations we may suspend or terminate without prior notice.
Accounts that are no longer used are deleted automatically: 12 months after the last use if nothing was ever purchased, 24 months after the last use if a program or subscription was purchased, and never while a subscription or program is active. We notify you by email twice beforehand; signing in to the App keeps the account. Details are set out in our Privacy Policy.
12. Service availability
We strive to keep the App available at all times but cannot guarantee uninterrupted access. The App may be temporarily unavailable due to maintenance, updates, or circumstances beyond our control.
We may modify the App to a reasonable extent, in particular to improve it, to reflect changes in the law, or for compelling technical or operational reasons. If we permanently discontinue the App or essential parts of it, we will announce this with reasonable advance notice. Any amounts prepaid for periods after a discontinuation, including the unused part of an 8-week coaching program, will be refunded on a pro-rata basis.
During the term of the contract, we provide the updates that are necessary to keep the App in conformity with the contract (including security updates) and inform you in the App when they are available. Installation takes place through the respective store.
We will inform you in the App and by email (in text form) about changes that go beyond what is necessary to maintain conformity with the contract. If such a change impairs your ability to access the App or its usability more than insignificantly, you may terminate the contract free of charge within 30 days of receiving the information or, if later, from the time of the change (Section 327r BGB). Any amounts already prepaid will be refunded on a pro-rata basis.
13. Liability
We provide the App with the care required by law. For defects in the App, the statutory rights for consumer contracts concerning digital products (Sections 327 et seq. of the German Civil Code, BGB) remain unaffected.
We are liable without limitation:
- for intent (Vorsatz) and gross negligence (grobe Fahrlässigkeit)
- for injury to life, body, or health, including where caused by simple negligence
- under the German Product Liability Act (Produkthaftungsgesetz)
- for fraudulent concealment of a defect and to the extent we have assumed a guarantee
In cases of simple negligence, we are otherwise liable only for the breach of an essential contractual obligation — an obligation whose fulfillment makes the proper performance of the contract possible in the first place and on whose fulfillment you may regularly rely. In that case, our liability is limited to the damage that is foreseeable and typical for this type of contract.
In all other respects, our liability is excluded. The above limitations also apply in favor of our legal representatives and vicarious agents.
14. Changes to these terms
We may update these Terms from time to time, for example to reflect changes in the law, new features, or changes to our services. If we make material changes, we will notify you in the App and ask for your renewed, active consent before you continue using the App. Minor changes (such as clarifications or editorial corrections) will be communicated in an appropriate manner and do not affect your existing rights.
15. Governing law and final provisions
These Terms are governed by the laws of the Federal Republic of Germany. Any disputes arising from or in connection with these Terms shall be subject to the jurisdiction of the competent courts in Germany, unless mandatory consumer protection laws of your country of residence provide otherwise.
We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board (Section 36 VSBG).
Should individual provisions of these Terms be or become invalid, the validity of the remaining provisions shall remain unaffected.
These Terms are available in German and English. In the event of discrepancies between the two versions, the German version prevails.
