07 Disclaimers & Liability

Liabilities We Do Not Exclude

Nothing in these Terms excludes or limits our liability for:

1. Death or personal injury caused by our negligence or wilful misconduct;
2. Fraud or fraudulent misrepresentation; or
3. Any other liability that cannot be excluded or limited under applicable law, including mandatory protections under the Singapore Consumer Protection (Fair Trading) Act (Cap. 52A).

Service Provided "As Is"

To the maximum extent permitted by applicable law, the App is provided on an "as is" and "as available" basis without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, or non-infringement.

We do not warrant that:

• The App will operate continuously, without interruption, or free from errors;
• The App will meet your specific requirements or expectations; or
• Any errors or defects will be corrected.

Limitation of Liability

To the maximum extent permitted by applicable law, we will not be liable for any:

• Indirect, incidental, special, consequential, or punitive damages;
• Loss of profits, revenue, data, or business opportunities;
• Damages arising from your inability to access or use the App; or
• Any health-related outcomes arising from use of the App's audio content, including but not limited to sleep quality, hearing health, or psychological wellbeing.

Our total aggregate liability to you for any claim arising out of or related to these Terms or your use of the App shall not exceed SGD 20 (twenty Singapore Dollars) or the equivalent in your local currency, being a nominal sum reflecting the App's free-of-charge nature.

Health Disclaimer

Consumer Statutory Rights

If you are a consumer in Singapore, nothing in these Terms affects your statutory rights under the Consumer Protection (Fair Trading) Act (Cap. 52A) or any other applicable consumer protection legislation.

08 Future Subscription Services

We may introduce an optional subscription tier in the future to offer enhanced content or features. If we do so:

• We will notify all existing users at least 30 days in advance via an in-app notice displayed on your next App launch, and through the App store update release notes (see Section 9 for how we deliver notifications).
• All core free features will remain available at no cost. No existing free features will be removed or placed behind a paywall.
• Detailed subscription terms — including pricing, billing cycles, auto-renewal terms, cancellation procedure, and applicable refund rights — will be published and communicated to you before any subscription is made available.
• All payments will be processed by Apple App Store or Google Play. We will not collect your payment card details directly.
• If you are a consumer in Singapore, you will be informed of any cancellation rights applicable to digital subscriptions at the time of purchase.

09 Agreement Changes & Notification

We may update these Terms from time to time. Because sleep sounds : X is a purely local, client-side application without persistent server communication, we deliver notifications through the following channels:

Notification Channels

• App store update notes: Material changes will be described in the "What's New" section of the App store update, published at least 30 days before the changes take effect.
• In-app notice: On the first launch following an App update containing changes to these Terms, you will see a notice. For material changes, you will be required to confirm your acceptance before continuing to use the App.

Categories of Change

We recommend enabling automatic App updates on your device so you receive policy change notifications promptly. Enabling automatic updates constitutes your agreement that App store update notes are valid notice of upcoming changes.

If you do not accept any material update, you may uninstall the App before the effective date of the change. Continued use after the effective date constitutes acceptance of the updated Terms.

10 Service Suspension & Termination

Suspension or Termination of Your Access

We may suspend or terminate your access to the App immediately and without prior notice if:

1. You breach any provision of these Terms;
2. You are found to be under 18 years of age; or
3. We are required to do so by law, regulation, or court order.

Temporary Service Interruptions

We may temporarily interrupt the App for maintenance or updates. For planned maintenance expected to exceed 24 hours, we will provide advance notice through an in-app notification delivered at the next App launch prior to the interruption.

Because the App functions primarily offline, such interruptions will typically have minimal impact on your ability to use its core features.

Permanent Discontinuation of the App

If we decide to permanently discontinue the App, we will:

• Provide at least 90 days' advance notice through an in-app notification and App store announcement;
• Handle your data in accordance with the then-current Privacy Policy;
• Allow you to submit a data deletion request at support@vongsion.com prior to service end.

Effect of Termination

Upon termination or expiry of your right to use the App for any reason, you must uninstall the App from your device. Sections 5 (Intellectual Property), 7 (Disclaimers and Liability), and 11 (Governing Law and Dispute Resolution) shall survive termination and continue in full force.

Termination by You

You may terminate these Terms at any time by uninstalling the App. Uninstallation automatically deletes all locally cached audio files. It does not automatically delete data held by Firebase; to request deletion of that data, please contact us at support@vongsion.com.

11 Governing Law & Dispute Resolution

Governing Law

These Terms are governed by and construed in accordance with the laws of the People's Republic of China.

If you are a consumer resident in Singapore, this choice of law does not deprive you of any protections afforded to you by the mandatory provisions of Singapore law, including the Consumer Protection (Fair Trading) Act (Cap. 52A). In the event of a conflict between these Terms and any such mandatory provision, the mandatory provision shall prevail.

Step 1 — Amicable Resolution

Before initiating any formal proceedings, both parties agree to attempt to resolve any dispute, controversy, or claim arising out of or in connection with these Terms in good faith through direct negotiation. Please contact us at support@vongsion.com with the subject line "Dispute Notice". We will respond within 30 days. We aim to resolve all disputes within 60 days of the initial notice.

Step 2 — Singapore Consumer Dispute Resolution

If you are a consumer in Singapore and your dispute is not resolved through direct negotiation, you may refer the matter to the following bodies before initiating arbitration:

• Competition and Consumer Commission of Singapore (CCCS): www.cccs.gov.sg
• Consumers Association of Singapore (CASE): www.case.org.sg
• Small Claims Tribunal — for claims of SGD 20,000 or below (or SGD 30,000 with mutual consent).

Step 3 — Arbitration

If a dispute is not resolved through the steps above within 60 days of the initial notice, either party may refer the dispute to final and binding arbitration administered by the Hong Kong International Arbitration Centre (HKIAC) in accordance with the HKIAC Arbitration Rules in force at the time of the dispute.

• Seat of arbitration: Hong Kong
• Language: English
• Number of arbitrators: One (1) sole arbitrator for claims below USD 100,000; three (3) arbitrators for claims of USD 100,000 or above.
• Arbitration fees: For claims arising from your personal use of this free App, we will bear the HKIAC filing and administrative fees.

The arbitration clause above does not prevent either party from seeking urgent interim or injunctive relief from a court of competent jurisdiction.

Singapore Consumer Court Rights Preserved

Nothing in this Section prevents a consumer resident in Singapore from bringing a claim before the Singapore Small Claims Tribunal or any other consumer dispute resolution body to which they are entitled under Singapore law, regardless of the arbitration clause above.
