DUPAMO Baby Sleep White Noise Terms of Service
Last Updated: September 11, 2026
Effective Date: September 1, 2026
These Terms of Service (the “Terms”) govern the rights, obligations, responsibilities, and other matters relating to the use of the “DUPAMO Baby Sleep White Noise” mobile application (the “App”) and all related services (the “Services”) provided by SGTHL (the “Operator”).
The App is a lifestyle assistance and entertainment application intended for parents, legal guardians, and other adult caregivers to use lullabies, white noise, nature sounds, and related features to help create a comfortable rest and sleep environment for infants and young children.
The direct users of the App are adults, including parents and caregivers. Infants and young children are recipients of sounds played by adult users and are not expected to directly operate or independently use the App. DUPAMO customization and completed-image saving features are also provided for adult users. By accessing or using the App after reviewing and agreeing to these Terms, the user agrees to be bound by them. Where separate consent is required for the processing of personal information, the Operator will obtain such consent separately from acceptance of these Terms.
Article 1 (Purpose)
The purpose of these Terms is to establish the conditions and procedures for use of the Services, including lullabies, white noise, nature sounds, classical music, recommended sound combinations, sound mixing, DUPAMO character customization, completed-image saving, and related services provided to adult users, as well as the rights, obligations, and responsibilities of the Operator and users.
Article 2 (Nature and Limitations of the Service)
The App is a lifestyle assistance and entertainment application providing lullabies, white noise, nature sounds, and other audio content that adult caregivers may use as supplementary tools to create a rest and sleep environment for infants, young children, and caregivers.
The App is not:
A medical device or equivalent product
A tool for medical diagnosis, treatment, or prevention
A treatment for sleep disorders, developmental disorders, anxiety symptoms, or other medical conditions of infants or children
A substitute for medicine or professional medical services
A device that medically guarantees sleep or calming of infants or children
A service that replaces direct care or supervision by a caregiver
The Operator does not guarantee that use of the App will result in:
Inducing sleep or increasing sleep duration
Eliminating crying, fussiness, or anxiety
Improving sleep quality
Promoting physical or emotional stability or development
Preventing, alleviating, or treating diseases or symptoms
Improving the caregiver’s sleep or stress
If an infant or child requires medical attention or there are concerns regarding sleep, breathing, hearing, development, or other health matters, caregivers should not rely on the App and should consult an appropriate healthcare professional.
Lullabies and sounds provided through the App should be used only as supplementary tools under appropriate caregiver supervision and do not replace direct observation and care.
Advertisements, reviews, social media posts, or influencer content produced independently by third parties that have no contractual, advertising, sponsorship, or partnership relationship with the Operator and that were not produced, commissioned, or approved by the Operator do not represent the Operator’s official position. Advertisements and promotional content produced, commissioned, or approved by the Operator are subject to the same descriptions and limitations of the Services stated in these Terms.
Article 3 (Definitions)
For purposes of these Terms:
“App” means the “DUPAMO Baby Sleep White Noise” mobile application provided by the Operator.
“Services” means all content and features provided through the App.
“User” means a parent, legal guardian, or other adult who agrees to these Terms and directly uses the Services. The Services are intended for adult use, and infants and young children who listen to audio content played by users are not considered direct users under these Terms.
“Caregiver” means a parent, legal guardian, or other adult who substantially protects, raises, or supervises an infant, child, or minor.
“Content” means sound recordings, images, characters, clothing items, text, animations, UI elements, and other materials.
“DUPAMO Customization” means an additional entertainment feature allowing adult users to customize a DUPAMO character by selecting clothing and decorative elements.
“Completed Image” means an image file saved to the user’s device showing the DUPAMO character customized by the user.
“Premium Service” means paid features or content available through a subscription or in-app purchase.
“App Marketplace” means the Apple App Store, Google Play, or any other platform through which the App is distributed.
Article 4 (Services Provided)
The Operator may provide the following Services:
Lullabies, white noise, nature sounds, and classical music
Situation-based recommended sounds and preconfigured presets
Sound mixing that allows users to select multiple sounds and adjust their volume
Timer, repeat playback, background playback, and user setting features
DUPAMO character customization and response animations
Saving completed DUPAMO images
Free Services containing advertisements
Premium Services offered through subscriptions or in-app purchases
Other features subsequently developed by the Operator
Available features may vary depending on the operating system, device performance, App version, region, and App Marketplace policies.
The Operator may change, add, or discontinue certain features for service improvement or operational reasons. Changes that materially affect users will be announced in advance where reasonably possible.
If the Operator materially reduces or terminates an essential paid feature so that a user cannot normally use a service during an already-paid period, the Operator will provide a refund, substitute service, or other reasonable compensation corresponding to the unavailable portion in accordance with applicable law and App Marketplace policies.
Article 5 (User Agreement and Eligibility)
A user agreement is formed when an adult user agrees to these Terms and uses the App or Services.
The Services are intended to be directly used by parents, legal guardians, and other adult caregivers and are not intended for infants or young children to directly operate or independently use.
When playing sounds for an infant or child or showing the App screen, the user is responsible for managing appropriate volume, device placement, screen exposure time, and the surrounding environment.
Paid purchases, subscription enrollment, opening external links, privacy-related consent, sharing functions, and changes to App settings should be performed directly by an adult user.
If a minor enters into an agreement for paid Services without the consent of a legal guardian, the minor or legal guardian may cancel the agreement in accordance with applicable law. Exceptions may apply where the minor has deceptively caused the other party to reasonably believe that the minor is an adult or has the guardian’s consent. Specific cancellation and refund procedures are governed by applicable law and the relevant App Marketplace procedures.
Where a paid-service agreement may be entered into by a minor, the Operator will provide legally required notice that the minor or legal guardian may cancel the agreement if guardian consent has not been obtained.
Article 6 (User Responsibilities for Infant and Child Safety)
When using the App around infants or children, users should:
Play at a low volume — keep the level from placing strain on an infant’s hearing.
Keep enough distance between the baby and the device — do not place a smartphone or speaker near an infant’s ears.
Avoid long continuous playback for newborns and use the timer — set a playback duration with the app’s sleep timer.
Keep charging cables, earphone cords, and devices out of reach of infants and children
Check devices for heat, damage, or electrical hazards
Prevent infants and children from placing devices in their mouths or throwing them
Avoid leaving a sleeping infant or child unattended for prolonged periods while relying on the App
Manage screen exposure so that infants and children do not look directly at the screen for excessive periods
All App features, including DUPAMO Customization, are intended to be directly operated by adult users. If a user shows the App screen to an infant or young child, the device should not be left with the child unsupervised for prolonged periods, and appropriate screen exposure and device safety should be maintained.
To the extent the Operator is not at fault, the Operator is not responsible for damage arising from a user’s failure to manage appropriate volume, duration of use, or device environment. Nothing in this provision excludes liability imposed by law for the Operator’s intentional misconduct or negligence.
Article 7 (User Obligations)
Users must not:
Interfere with normal operation of the App
Use the App for unlawful purposes
Infringe intellectual property rights of the Operator or any third party
Reproduce, distribute, or sell sound recordings, characters, clothing, images, or other Content without authorization
Hack, reverse engineer, decompile, disassemble, or attempt to extract source code except to the extent expressly permitted by applicable law
Fraudulently use or manipulate advertising or payment systems
Use another person’s account or payment method without authorization
Falsely represent or advertise the App or Content as having medical efficacy
Use DUPAMO characters or Completed Images for illegal, obscene, hateful, or violent purposes
Violate applicable terms of Apple, Google, or other third-party services
Violate any applicable law
If a user violates these Terms or applicable law, the Operator may restrict access to the Services or terminate the user agreement depending on the nature and severity of the violation and operational necessity.
Article 8 (Advertising and Third-Party Services)
The App may contain advertising to support the free Services.
The Operator may use advertising, statistics, analytics, and diagnostic services for service provision, quality improvement, usage analysis, and error analysis.
The App is a general application whose direct users are parents, legal guardians, and other adult caregivers. Infants and young children are not intended to be direct users or advertising targets.
When advertising and analytics services are used, the Operator will comply with applicable laws and App Marketplace policies based on the actual adult users of the App. The Operator does not operate the Services for the purpose of collecting children’s personal information or providing personalized advertising targeted at children.
The names of advertising, analytics, and crash-reporting services actually used, categories of information processed, purposes, retention periods, processing arrangements, third-party disclosure, and international transfers are described in the Privacy Policy.
If the App’s direct target users, functions, or operating model change so that children become direct users, the Operator will implement required measures under applicable law and App Marketplace child-protection policies before such changes and will revise these Terms and the Privacy Policy.
Third-party advertisements and external services are provided by the relevant third parties. The Operator is not responsible for damage caused without fault on the part of the Operator. This does not exclude legal liability arising from advertisements directly selected, produced, or approved by the Operator or from the Operator’s intentional misconduct or negligence.
Article 9 (Paid Services and Subscriptions)
Certain Content and features may be offered for a fee.
Prices, billing periods, automatic renewal, free-trial periods and post-trial charges, included features, subscription cancellation methods, and any restrictions on withdrawal will be clearly disclosed on the purchase screen.
Payments are processed through the payment system of the App Marketplace from which the user downloaded the App.
Unless cancelled before the end of the current subscription period in accordance with the procedures and timing specified by the relevant App Marketplace, an automatically renewing subscription may renew for the same or another period disclosed on the purchase screen.
Users may manage subscriptions through:
Apple: device Settings or subscription management within the App Store account
Google Play: Payments & subscriptions or the relevant subscription-management menu in Google Play
Cancellation of a subscription generally does not terminate access immediately. Paid features may continue to be available until the end of the already-paid subscription period. Refund eligibility is governed by applicable law and the relevant App Marketplace policies.
If subscription pricing or service conditions change, the Operator will disclose the changes and their effective date in accordance with the relevant App Marketplace procedures and applicable law and obtain user consent where required.
Article 10 (Withdrawal and Refunds)
Users may exercise rights of withdrawal regarding paid Services within seven days from the date on which the legally required contract information was received, in accordance with applicable law. If supply of the paid Service begins later, the seven-day period may run from the date supply begins.
If paid Services are provided differently from their description, advertisement, or agreed terms, users may exercise applicable withdrawal rights within three months from the date of supply or within 30 days from the date they became aware or reasonably could have become aware of the discrepancy, in accordance with applicable law.
Withdrawal rights may be restricted once digital content has begun to be supplied where permitted by law. Before purchase, the Operator will clearly disclose applicable restrictions and, where required, provide previews, partial use, limited trials, or sufficient information about the content.
For products consisting of multiple items or Services provided over a period of time, withdrawal may remain available with respect to separable portions for which supply has not yet begun, as permitted by law.
Cancellations, refunds, and subscription termination for products purchased through an App Marketplace are generally processed through the procedures of that App Marketplace. The Operator may not be able to independently alter payment or refund decisions processed by the App Marketplace. App Marketplace policies do not limit statutory consumer rights.
Where a withdrawal is lawfully exercised, the Operator will refund the payment or request the relevant App Marketplace to issue a refund or cancel the transaction within the period required by applicable law.
The App does not guarantee that it will induce sleep, calm an infant or child, or improve sleep. Failure to achieve an expected sleep or calming effect does not itself create an independent right to a refund, but statutory rights concerning withdrawal, termination, refunds, or damages remain unaffected.
Article 11 (Intellectual Property Rights)
Rights in the following materials included in the App belong to the Operator or their lawful rights holders:
DUPAMO characters and character names
DUPAMO clothing and graphics
Sound recordings, lullabies, nature sounds, and sound effects
App icons, logos, UI, and design
Animations, text, and other Content
Users receive only a personal, non-commercial, non-exclusive, non-transferable license to use the Content for purposes of using the Services.
Without prior written permission from the Operator, users may not reproduce, modify, distribute, sell, or create derivative works from the Content.
Completed DUPAMO images created using the image-saving feature may be used for personal enjoyment, sharing with family, and non-commercial social media posting.
Prior written permission from the Operator is required to use Completed Images for commercial purposes, including merchandise, advertising, NFTs, paid content, or character-related businesses.
Except as expressly permitted in this Article, use of the App or Services does not transfer or implicitly license ownership, trademark rights, copyrights, or any other intellectual property rights in the Content.
Article 12 (DUPAMO Customization and Completed-Image Saving)
DUPAMO Customization is an additional entertainment feature allowing adult users to customize DUPAMO characters by selecting clothing and decorative elements.
DUPAMO Customization and completed-image saving are not intended for direct use by infants or young children and are designed to be operated by adult users.
The Operator does not guarantee that specific clothing items, animations, response effects, or saving functions will operate identically on every device.
The completed-image saving feature saves an image of the customized DUPAMO character to the device’s photo library or similar storage and does not photograph the user or an infant or child.
Depending on the operating system, permission to access the photo library or media storage may be required to save a Completed Image. The Operator requests permissions only to the extent necessary to provide the feature.
In the current version of the App, Completed Images created by users are not transmitted to or stored on the Operator’s servers and are stored only on the user’s device. If server storage, backup, or synchronization is introduced in the future, users will be informed before implementation, separate consent will be obtained where required by law, and the Privacy Policy will be revised.
If a user sends a Completed Image to an external app or social media service using the device’s sharing function, the terms and privacy policy of the relevant external service will apply.
Where an image cannot be saved due to insufficient storage, denial of access permission, operating system errors, or problems with an external sharing service, the Operator is not responsible for damage occurring without fault on the Operator’s part. Liability imposed by law for the Operator’s intentional misconduct or negligence is not excluded.
Article 13 (Changes to or Suspension of the Services)
The Operator may temporarily change or suspend all or part of the Services in the following circumstances:
System inspection or maintenance
Server or communications failure
Changes to operating system or App Marketplace policies
Changes to Content rights or licenses
Urgent security measures
Natural disasters or other force majeure events
Other reasonable operational necessities
Where advance notice is reasonably possible, the Operator will provide notice of the reason, scope, and expected duration of a Service change or suspension through an in-App notice or other appropriate method. In urgent security situations or force majeure circumstances where advance notice is impracticable, notice may be provided promptly afterward.
If an essential paid feature is discontinued or the Service is terminated, the Operator will provide advance notice where reasonably possible and provide refunds, substitute services, or other reasonable compensation for paid periods that could not be provided, in accordance with applicable law and App Marketplace policies.
Article 14 (Disclaimers and Limitation of Liability)
The Operator does not represent that the App is a medical service or medical device and does not guarantee any particular health effect for infants, children, or caregivers.
The Operator does not guarantee:
Sleep induction or calming of infants or children
Improvement in sleep duration or sleep quality
Reduction of crying, fussiness, anxiety, or stress
Promotion of physical, cognitive, language, or emotional development
Prevention, alleviation, or treatment of diseases or symptoms
If a user delays or fails to obtain necessary medical care by relying on the App despite clear notice of its nature and limitations, the Operator is not responsible for resulting damage to the extent the Operator is not at fault.
The Operator is not responsible, to the extent the Operator is not at fault, for problems arising from user-controlled volume settings, device placement, duration of use, insufficient care or supervision, device environment, or network conditions.
The Operator is not responsible, to the extent the Operator is not at fault, for damage resulting from the acts or failures of App Marketplaces, telecommunications providers, external links, third-party advertisements, or external services.
If the Services cannot be provided due to natural disasters, war, power outages, telecommunications failures, App Marketplace actions, or other circumstances beyond the Operator’s reasonable control, the Operator will not be liable to the extent permitted by applicable law.
All disclaimers and limitations of liability in these Terms apply only to the extent permitted by applicable law. These Terms do not exclude or improperly restrict liability arising from the Operator’s intentional misconduct or negligence or any statutory consumer rights.
Article 15 (Privacy Protection)
The Operator protects users’ personal information in accordance with the Personal Information Protection Act of the Republic of Korea and other applicable laws.
Categories of personal information collected or processed, processing purposes, retention periods, third-party provision, processing arrangements, international transfers, and destruction are governed by the separate Privacy Policy.
The App does not treat infants or children under the age of 14 as direct users and is not designed to directly collect personal information from children.
If the Operator later introduces features collecting a child’s name, date of birth, photograph, voice, sleep records, health information, or other personal information, users will be informed before implementation, and consent from a legal guardian will be obtained where required by applicable law.
Where user consent is required for personal information processing, the Operator will separately present and obtain consent for collection and use, third-party provision, international transfer, and other consent items so that users can clearly understand each matter.
If advertising, analytics, or crash-reporting SDKs process device information or similar data, the Operator will accurately disclose the applicable processing in the Privacy Policy and App Marketplace data-disclosure sections.
Users and legal guardians may exercise rights of access, correction, deletion, suspension of processing, and withdrawal of consent with respect to their own personal information or a child’s personal information they lawfully represent, as provided by applicable law. Details are provided in the Privacy Policy.
The Privacy Policy will be available through the App’s settings screen and a link on the App Marketplace product page.
All privacy-related inquiries may be submitted to sgthl20@gmail.com.
Article 16 (Changes to the Terms)
The Operator may amend these Terms to the extent permitted by applicable law.
When these Terms are amended, the effective date and details of the changes will generally be announced at least seven days before the effective date.
Changes that are disadvantageous to users or materially affect paid Services, privacy, disclaimers, or user rights will generally be announced at least 30 days before the effective date. Where the Operator possesses the user’s contact information and individual notice is legally required or reasonably necessary, additional notice may be provided by email, App notification, or another appropriate method.
Users who do not agree to amended Terms may discontinue use of the Services and terminate the user agreement.
Where applicable law requires separate consent to a particular change, the Operator will obtain separate consent and will not treat continued use of the Services alone as consent to matters that legally require express consent.
Article 17 (Dispute Resolution)
The Operator and users will make reasonable efforts to resolve disputes relating to the Services through mutual consultation.
If a dispute cannot be resolved through consultation, users may seek consultation or mediation from the Korea Consumer Agency, Content Dispute Resolution Committee, Personal Information Dispute Mediation Committee, or another relevant authority.
Article 18 (Governing Law and Jurisdiction)
These Terms are governed by and construed in accordance with the laws of the Republic of Korea.
Jurisdiction over disputes arising from these Terms will be determined in accordance with the Civil Procedure Act of the Republic of Korea and other applicable laws.
Article 19 (Apple-Specific Terms)
These Terms are entered into between the Operator and the user, not with Apple.
Responsibility for the App and Services rests with the Operator to the extent permitted by applicable law.
Users are granted a non-exclusive, non-transferable license to use the App on Apple-branded products that they own or control, subject to the Usage Rules set forth in the Apple Media Services Terms and Conditions. Other accounts associated with the purchaser may access and use the App through Family Sharing, volume purchasing, or other methods permitted by Apple.
Maintenance and support services for the App are provided by the Operator as required under applicable law and these Terms. Apple has no obligation to provide maintenance or support services for the App.
If the App fails to conform to an applicable warranty, the user may notify Apple, and Apple may refund the purchase price of the App in accordance with applicable policies. To the maximum extent permitted by applicable law, Apple has no other warranty obligations with respect to the App, and other claims attributable to a failure to conform to a warranty are the responsibility of the Operator.
The Operator, not Apple, is responsible for addressing claims relating to the App or the user’s possession or use of the App, including product-liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims arising under consumer-protection or privacy laws.
If a third party claims that the App or the user’s possession or use of the App infringes that third party’s intellectual property rights, the Operator, not Apple, is responsible for the investigation, defense, settlement, and resolution of the claim.
The user represents and warrants that the user is not located in a country or region subject to a U.S. Government embargo or designated by the U.S. Government as supporting terrorism, and is not listed on any U.S. Government list of prohibited or restricted parties.
Users must comply with applicable third-party terms, including those of telecommunications providers and third-party services used by the App.
Apple and its subsidiaries are third-party beneficiaries of these Terms. Upon the user’s acceptance of these Terms, Apple has the right to enforce these Terms against the user as a third-party beneficiary.
Apple and App Store are trademarks of Apple Inc.
Article 20 (Google Play-Specific Terms)
These Terms are entered into between the Operator and the user, not with Google.
Google is not responsible for development, Content, maintenance, or customer support for the App.
Payments, subscription management, and refunds through Google Play are subject to Google Play policies and procedures. Such policies do not limit rights provided to users under applicable law.
The Operator will accurately declare target age and content information in Google Play Console so that it is consistent with the App’s actual direct users, functionality, store description, and marketing materials, and will comply with applicable Google Play policies.
Google and Google Play are trademarks of Google LLC.
