By downloading, installing, registering, signing in, or otherwise using the Service, you acknowledge that you have read, understood, and agree to be bound by these Terms in their entirety.

  1. By completing any of the actions above, you are deemed to voluntarily accept and be bound by these Terms.
  2. We may revise these Terms from time to time based on legal requirements, product adjustments, or operational needs.

2. Description of the Service

  1. The App is a white noise / ambient sound playback and mixing tool for sleep assistance, and also provides an AI audio generation feature to help you create a relaxing sleep environment.
  2. The App is not a medical device and does not provide any medical diagnosis, treatment, or health advice. If you have sleep disorders or health concerns, please consult a qualified physician. We make no guarantee regarding the sleep-enhancing effect of the App.
  3. We will use reasonable efforts to keep the Service available, but do not guarantee that it will be uninterrupted or error-free. We reserve the right to add, adjust, or discontinue any part or all of the features (free or paid) at any time, and will notify you in advance or promptly through reasonable means.

3. Account and Sign-In

  1. The App provides account services through Sign in with Apple; sign-in is also subject to Apple's applicable terms.
  2. You are responsible for ensuring the authenticity and legality of your sign-in identity, and for all activity under your account. You bear any losses caused by your failure to safeguard your account.
  3. You may not transfer, lend, or share your account with others for commercial purposes.
  4. If you believe your account has been compromised or is at risk, contact us immediately.

4. AI Audio Generation

  1. Nature of the feature: AI audio is generated automatically by a machine model based on your text prompt, and the results are somewhat random. We do not guarantee that the generated content will meet your expectations, and make no express or implied warranty as to the availability, accuracy, completeness, or artistic quality of the results.
  2. Usage allowance:
    • Subscribers receive a monthly allocation of AI audio generations (currently 5 per month), as displayed in the App;
    • The monthly allowance is calculated by calendar month; unused allowance does not carry over.
  3. Input content standards: You agree not to use this feature to generate content that violates applicable law or public morality, including but not limited to content involving violence, terrorism, discrimination, infringement of others' intellectual property or personal rights, defamation, pornography, or false information. We may, without further notice, refuse to generate, delete, or restrict features in response to violations.
  4. Use of generated content: AI-generated content is for your personal, non-commercial use only (unless you have obtained the relevant authorization). You are responsible for ensuring that your use of generated content does not infringe any third-party rights; you bear any disputes and liabilities arising from your use of the generated content.
  5. Storage of generated content: Generated audio files are stored in the cloud; we may clean them up after a long period of inactivity or after account deletion, so please save important content promptly. We are not liable for any interruption or loss of the storage service.

5. Subscriptions and Auto-Renewal (Important)

  1. The App offers auto-renewing subscriptions; the specific tiers, prices, and entitlements are as displayed on the in-app purchase page (Apple App Store).
  2. Auto-renewal rules:
    • Subscriptions are completed through the Apple App Store, and payment is collected by Apple on our behalf;
    • Within 24 hours before your subscription expires, unless you manually turn off auto-renewal, Apple will automatically charge your Apple ID account for the next period, and the subscription will be extended by one period;
    • To cancel auto-renewal, go to your iPhone Settings → [your Apple ID] → Subscriptions at least 24 hours before the current period ends and manage or cancel it. After cancellation, the Service remains active for the current period, and will not renew after it expires;
    • Charges already deducted are generally non-refundable, except as required by law.
  3. Restore Purchases: After changing devices or reinstalling the App, you can use "Restore Purchases" to restore your purchased subscription entitlements.
  4. Management of subscriptions (refunds, downgrades, upgrades, Family Sharing, etc.) is governed by Apple's applicable terms and is ultimately decided by Apple. If you have a billing dispute, you may contact Apple Support directly.
  5. Free trial rules (if any): If you subscribe during a free trial, any unused trial period may be forfeited, subject to Apple's rules.

  1. All content in the App — including software, interface, icons, built-in sound effects (unless otherwise noted), copy, and trademarks — is owned by us or the relevant rights holders and is protected by applicable law.
  2. Without our written permission, you may not copy, modify, distribute, rent, sell, reverse-engineer, or decompile any part of the App, or use it for commercial purposes.
  3. Content you generate using the AI feature: To the extent permitted by applicable law, you may use your generated audio for personal, non-commercial purposes; for commercial use, you must confirm and obtain the necessary authorizations yourself. We do not claim ownership of your generated content, but you understand that some jurisdictions impose limitations on the copyrightability of purely AI-generated content.

  6. Redistribute the Service or its content commercially without permission;
  7. Otherwise violate applicable law, these Terms, or public morality.
