Supplemental Terms and Conditions for Night Light Assistant

Developer: Yang Liu

Effective Date: December 3, 2025

IMPORTANT NOTICE: These Supplemental Terms and Conditions (the "Supplemental Terms") constitute a legally binding agreement between you (the "User") and the Developer concerning the Night Light Assistant application (the "App"). These Supplemental Terms serve as an addition and extension to the Standard Apple End User License Agreement (Standard EULA). By downloading, installing, or using the App, you signify your agreement to both these Supplemental Terms and the Standard EULA. In the event of any conflict between these Supplemental Terms and the Standard EULA regarding the specific features of the App, these Supplemental Terms shall govern.

1. Service and Usage License

This document supplements the Standard EULA and governs your use of the Night Light Assistant App.

  • Limited License: The Developer grants you a non-exclusive, non-transferable, limited license to use the Service and all its features and content, strictly for personal, non-commercial purposes, and within the limits set forth in the Standard EULA.
  • Non-Medical Disclaimer: The User expressly acknowledges and agrees that the functions provided by the App (including night light, ambient sound, or sleep assistance features) are intended for entertainment, relaxation, or personal aid purposes only. The Service is not intended to provide medical advice and is not a substitute for professional diagnosis, treatment, or medical care. The Developer is not liable for any health decisions or outcomes based on the use of the App.
  • Safety Responsibility: The User is solely responsible for adjusting the device's screen brightness, volume, and other settings to safe and comfortable levels. The Developer assumes no liability for any eye strain, hearing impairment, or other physical discomfort resulting from the improper use of the App.

2. Use Restrictions and Prohibited Conduct

Your permission to use the Service is conditioned upon your agreement that you will not:

  • Unauthorized Access: Access, tamper with, or use any non-public code, systems, or data of the Service without authorization.
  • Interference: Interfere or attempt to interfere with the proper functioning, security, or network of the Service.
  • Automated Misuse: Engage in automated use of the Service (e.g., using bots, spiders, or data mining tools), or take any action that we deem to impose or potentially impose an unreasonably large load on the Service.
  • Legal Compliance: Use the Service in any manner that violates applicable laws, regulations, or the Standard EULA.

3. Intellectual Property and Content Ownership

  • Developer Ownership: The Developer retains all right, title, and interest in and to the Service, including all proprietary content, features, design, source code, graphics, audio files (including all white noise and ambient sounds), trademarks, and all related intellectual property rights ("App Content").
  • Prohibition on Reproduction: You may not copy, modify, translate, reverse-engineer, decompile, disassemble, or create derivative works of the Service or the App Content, except as permitted by the Standard EULA. Specifically, you may not extract any audio or visual elements from the Service for commercial use outside the App.

4. Payments and Billing

The Service may offer enhanced features through one-time purchases or recurring subscriptions ("Paid Features").

  • Marketplace Provider: All transactions for Paid Features are handled by the authorized Marketplace Provider (e.g., the Apple App Store). You must have an active account and a valid payment method ("Payment Method") with the Marketplace Provider.
  • Processing: Payments will be processed by the Marketplace Provider, not directly by the Developer. All inquiries related to payment failure or disputes must be directed to the Marketplace Provider.

5. Subscription Terms

5.1 Auto-Renewal

  • Periodic Billing: All Subscriptions are set to auto-renew by default. Unless you cancel your Subscription as specified below, the Marketplace Provider will continually charge the subscription fee ("Subscription Fee") to your Payment Method according to your designated cycle (e.g., monthly, annually).
  • Renewal Charge: The Subscription Fee and applicable taxes will be charged by the Marketplace Provider to your Payment Method within 24 hours prior to the end of the current billing cycle.

5.2 Cancellation and Effect

  • Cancellation Responsibility: You must cancel your Subscription directly through your Apple Account Settings. Deleting or uninstalling the App does not automatically cancel your Subscription.
  • Cancellation Effect and Non-Refundable:
    • If you cancel the auto-renewal, your access to the Service will continue until the end of the current paid term.
    • NO REFUNDS WILL BE PROVIDED FOR ANY CANCELLATION MID-TERM. You agree that you will not receive any prorated or full refund for the current paid term upon cancellation.

5.3 Free Trials and Promotional Offers

  • Automatic Conversion: If the App offers a free trial ("Trial Period"), the Subscription will automatically convert to a paid subscription and billing will commence upon the expiration of the Trial Period.
  • NO OBLIGATION TO NOTIFY: The User expressly acknowledges and agrees that neither the Developer nor the Marketplace Provider is obligated to notify the User before the Trial Period ends. It is the User's sole responsibility to cancel the Subscription at least 24 hours prior to the Trial Period end date to avoid being charged.

6. Supplemental Limitation of Developer Liability

In addition to the limitations set forth in the Standard EULA, the Developer's total liability to you for all damages shall be limited as provided in Section 10 below.

7. Indemnification

You agree to defend, indemnify, and hold harmless the Developer and its affiliates, officers, directors, employees, and agents from and against all claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or in any way relating to: your use or misuse of the App, your breach of these Supplemental Terms or the Standard EULA, or your infringement of any third-party rights. This indemnification obligation will survive the termination of these Terms.

8. Privacy Policy and User Data

The Developer has published a separate Privacy Policy, which details how the Developer collects, uses, and protects user data. Your use of the App signifies your agreement to all terms of the Privacy Policy.

9. External Services and Third-Party Links

The Service may provide links to third-party websites or services ("External Services"). You agree to use any External Services at your sole risk. The Developer has no control over and is not responsible for the content, accuracy, or security of any External Services.

10. NO WARRANTY & LIMITATION OF LIABILITY

  • DISCLAIMER: YOUR USE OF THE SERVICE IS AT YOUR SOLE RISK. The Service is provided on an "AS IS" and "AS AVAILABLE" basis, with all faults and without warranty of any kind. The Developer expressly disclaims all warranties, express or implied, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose.
  • LIMITATION OF LIABILITY: To the extent not prohibited by law, in no event shall the Developer be liable for any direct, indirect, incidental, special, consequential, or exemplary damages, including, without limitation, damages for loss of profits, data, or business interruption, regardless of the theory of liability. The Developer's total liability to you for all damages shall not exceed the amount of fifty dollars ($50.00).

11. General Provisions

  • 11.1 Entire Agreement: These Supplemental Terms, the Standard EULA, and the Privacy Policy constitute the entire agreement between you and the Developer regarding the use of the App.
  • 11.2 Severability: If any part of these Terms is deemed invalid or unenforceable by a court of competent jurisdiction, that part shall be interpreted to reflect the Developer’s original intent, and the remainder of these Terms shall remain in full force and effect.
  • 11.3 Waiver: The Developer’s failure or delay in exercising any right under these Terms shall not be deemed a waiver of that right or any future right.
