If you are a parent or guardian and believe your child has used this App, please contact us at support@vongsion.com.

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable licence to download, install, and use the App on a compatible Android device that you own or personally use, solely for your personal, non-commercial purposes.

05 Intellectual Property

Our Own Content

The App and all content originally created by Vongsion (Beijing) Technology Co., Ltd. — including but not limited to audio recordings, interface design, graphics, software code, and branding — are owned by us and are protected under the intellectual property laws of the People's Republic of China, the Singapore Copyright Act 2021, and applicable international treaties including the Berne Convention for the Protection of Literary and Artistic Works. All rights are reserved.

We will acknowledge valid complaints within 72 hours and take appropriate action upon verification.

06 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 100 (one hundred Singapore Dollars) or the equivalent in your local currency, being a nominal sum reflecting the App's free-of-charge nature.

This cap reflects the fact that the App is provided free of charge and that you receive the App without payment of any consideration. It does not apply to liabilities that cannot be excluded or limited under applicable mandatory law, including the Consumer Protection (Fair Trading) Act (Cap. 52A) and the Personal Data Protection Act 2012 (PDPA).

Future paid services: If and when we introduce a paid subscription tier (see Section 7), the liability cap applicable to paid subscribers will be revised at that time and communicated to you in the updated Terms, which will be notified at least 14 days in advance. The revised cap for paid users will not be less than the total fees paid by that user in the 12 months immediately preceding the claim.

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.

07 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 14 days in advance via an in-app pop-up notice displayed on your next App launch, and through the App store update release notes (see Section 8 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 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.

Refunds for any subscription purchases are subject to the refund policy of Google Play at the time of purchase. We do not process subscription refunds directly; refund requests should be submitted through Google Play, the platform from which the subscription was purchased.

08 Agreement Changes & Notification

We may update these Terms from time to time. We deliver notifications for changes to these Terms through the following channels:

Notification Channels

• In-app pop-up notification (material changes): For material changes (e.g. introduction of subscription fees, expansion of data use, change of dispute resolution mechanism or governing law), an in-app pop-up will be displayed on your next App launch. You will be asked to review and confirm your acceptance before continuing to use the App. The pop-up will appear at least 14 days before the changes take effect.
• In-app badge indicator (non-material changes): For non-material changes (e.g. typographical corrections, contact detail updates, clarifications with no change to user rights), we will update the document date and display a red dot badge on the Terms of Service entry in Settings → About. The badge will remain visible until you open and view the updated document. No confirmation or acceptance is required.
• App store update notes: Changes may also be described in the "What's New" section of the App store update where applicable.

Categories of Change

• Material changes (e.g. introduction of subscription fees, expansion of data use, change of dispute resolution mechanism or governing law) — at least 14 days' advance notice; in-app pop-up confirmation required to continue use. The pop-up notice will also disclose any non-material corrections made since the previous version.
• Non-material changes (e.g. typographical corrections, contact detail updates, clarifications with no change to user rights) — the document date is updated and a red dot badge is displayed on the Terms of Service entry in Settings → About until you open and view the updated document. No confirmation or acceptance is required.

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.

09 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.

Permanent Discontinuation of the App

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

• Provide at least 30 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 dpo@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), 6 (Disclaimers and Liability), 10 (Governing Law and Dispute Resolution), and 13 (Entire Agreement) 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 our Data Protection Officer at dpo@vongsion.com.

10 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.

Mandatory local protections preserved. If you are a consumer resident in Singapore, the choice of PRC governing law does not deprive you of the mandatory protections afforded to you under the laws of Singapore. Specifically, any term of these Terms that would be unenforceable or void under the Consumer Protection (Fair Trading) Act (Cap. 52A), the Unfair Contract Terms Act (Cap. 396), or the Personal Data Protection Act 2012 (PDPA) shall, to the extent of such inconsistency, be read and enforced in accordance with those Singapore laws. You may enforce your Singapore consumer and data protection rights before the Singapore courts, the Small Claims Tribunal, and/or the Personal Data Protection Commission (PDPC), regardless of the governing law clause above.

For all other matters not governed by the mandatory consumer or data protection laws of Singapore, these Terms shall be interpreted in accordance with PRC law as stated above.

Dispute Resolution

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 — Local Consumer Remedies

If you are a consumer, nothing in these Terms prevents you from seeking relief through the consumer protection bodies or small claims tribunals in your country of residence before resorting to arbitration. For Singapore users, this includes:

• 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

For disputes where the amount in controversy exceeds SGD 5,000, and the dispute is not resolved through Steps 1 and 2 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. If you require assistance in another language, you may request reasonable translation arrangements, which we will not unreasonably withhold.
• Number of arbitrators: One (1) sole arbitrator.
• Expedited Procedure: For claims where the amount in controversy is below HKD 3,000,000, the arbitration shall be conducted under the HKIAC Expedited Procedure rules in force at the time.
• Arbitration fees: The arbitration fees (including the HKIAC filing fee, administrative fee, and the arbitrator's fees and expenses) shall be fixed and allocated by the arbitral tribunal in accordance with the HKIAC Arbitration Rules then in force.

For the avoidance of doubt, the arbitration proceedings shall be conducted in accordance with the HKIAC Arbitration Rules (procedural law of Hong Kong), while the merits of any dispute shall be determined in accordance with the governing law of these Terms (PRC law), subject to the mandatory local protections set out above.

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

Consumer Arbitration Opt-Out

Low-Value Disputes (SGD 500 or Below)

For disputes where the amount in controversy is SGD 500 or less, we will endeavour to resolve the matter through email-based negotiation without requiring formal proceedings of any kind. To initiate this process, please email support@vongsion.com with the subject line "Low-Value Dispute". We aim to resolve such matters within 30 days. If email-based negotiation does not result in resolution, you may pursue the matter through the Singapore Small Claims Tribunal in accordance with the Small Claims Exclusion above. This provision does not waive any of your statutory rights.

Singapore Consumer Rights Preserved

For the avoidance of doubt, nothing in this Section (including the arbitration clause above) prevents a consumer resident in Singapore from:

• Bringing a claim before the Singapore Small Claims Tribunal (for claims up to SGD 20,000, or SGD 30,000 with mutual consent);
• Seeking relief through the Competition and Consumer Commission of Singapore (CCCS) or the Consumers Association of Singapore (CASE);
• Lodging a complaint with the Personal Data Protection Commission (PDPC); or
• Pursuing any other remedy available under Singapore law.

11 Force Majeure

We shall not be liable for any failure or delay in performance under these Terms due to circumstances beyond our reasonable control, including but not limited to acts of God, war, terrorism, civil unrest, governmental orders, internet or telecommunications failures, or cyber attacks ("Force Majeure Event"). We will make reasonable efforts to notify you of any Force Majeure Event and to resume performance as soon as practicable. If a Force Majeure Event continues for more than 30 days, either party may terminate these Terms by providing written notice to the other party.

12 Severability

If any provision of these Terms is found to be unenforceable or invalid by a court of competent jurisdiction, that provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.

13 Entire Agreement

These Terms, together with our Privacy Policy, constitute the entire agreement between you and Vongsion (Beijing) Technology Co., Ltd. regarding your use of the App and supersede all prior understandings, communications, representations, or agreements, whether oral or written, relating to the subject matter of these Terms.
