Moonmic Terms of Service

First Published: October 22, 2026

1. Purpose and Definitions

These Terms of Service set out the rights, obligations, and responsibilities between CodeSand Co., Ltd. (the "Company") and users in connection with the use of the mobile application "Moonmic" (the "Service") provided by the Company.

• Service: the Moonmic application and ancillary services that save only the moments with sound picked up by the phone's microphone during the night, show the record in the morning, and play bedtime sounds before sleep.
• User: any person who agrees to these Terms and uses the Service.
• Paid Product: the Unlock all features product sold through in-app purchase on the Apple App Store or Google Play.
• Clip: a short audio file saved on the user's device containing the moments before and after a sound during night recording, together with its attached time, duration, sound level, and classification label.
• Night Record: the summary saved on the device for one night of recording (recording duration, number of detections, totals per label, baseline, and so on) and the tags the user attached to that night.
• Bedtime Sounds: the noise, nature-sound, and music tracks included in the Service for playback before sleep.

2. Effect and Amendment of the Terms

These Terms take effect upon being posted on the Service website, and users may view them at any time from the Settings menu in the app.

The Company may amend these Terms to the extent that the amendment does not violate applicable laws.

Changes that are not unfavorable to users are posted on the Service website with the details of the amendment and the effective date, and take effect upon posting. Feature additions, wording improvements, clarification of collected or used items, and correction of clerical errors fall into this category.

Changes that are unfavorable to users are posted on the Service website with the details of the amendment and the effective date at least 30 days before the effective date. Changes that reduce users' rights or impose new obligations, discontinuation of features previously provided, and reduction of refund conditions fall into this category.

If a user continues to use the Service after the effective date of an amended version, the user is deemed to have agreed to it. A user who does not agree may stop using the Service at any time, and termination of the use agreement is governed by Section 11.

3. Provision of the Service

The Company provides the functions needed to achieve the purpose of the Service. The specific composition of each function and how to use it are described on the app's screens, and the list below is illustrative of the nature of the Service and does not limit the functions the Company provides.

• Detecting sounds during the night and saving, playing, classifying, and exporting Clips
• Viewing the morning summary and Night Records, night tags, and tag comparisons
• Playing Bedtime Sounds before sleep with a sleep timer
• Recording settings such as sensitivity and retention, and purchasing and restoring Unlock all features
• Any other functions the Company additionally develops or provides through partnerships

The Service requires microphone access permission for night recording. If the permission is not granted, recording and detection cannot be used and only Bedtime Sounds playback is available. On Android the app requests notification permission to show a persistent notification while recording; recording works even if it is declined. How microphone input is processed and what is stored are set out in Section 5, and the matters users must observe are set out in Sections 4 and 6.

The Company may change, add, or discontinue individual functions to improve the quality of the Service and operate it stably. However, changes that materially affect users, such as discontinuation of the entire Service, are posted in advance in the manner set out in Section 2.

The Service is in principle provided year-round, but it may be temporarily suspended for substantial reasons such as system maintenance, equipment replacement, or failures of external services. In such cases the Company gives advance notice where reasonably possible and resumes the Service without delay once the cause is resolved. Because the Service does not keep user data on a server, such suspensions in principle do not affect the use of data stored on the device.

If the Company terminates the provision of the entire Service, it posts a notice on the Service website at least 30 days in advance. Users may save the Clips they wish to keep with the clip export function before termination.

4. Limits of the Service and User Responsibility

This section contains matters you must understand before using the Service. The Service has the following limits, and users use the Service with an understanding of them. Section 13 (Disclaimer) is premised on this section.

(a) The Service is a recording and logging tool, not a medical device

• The Service only records the moments at night when sound occurs and logs their count, time, and duration. It does not determine the presence of any condition such as sleep apnea, the quality of your sleep, or any health risk, and it is not designed to serve as a basis for such determinations. The Service is not a medical device under the Medical Devices Act of Korea and holds no medical-device certification in any country.
• The "snoring", "speech", and "other" labels and the detection counts and totals the Service shows are reference information produced by mechanically classifying sounds picked up by the phone's microphone; they are not medical or scientific measurements.
• Users must not start or stop treatment, or substitute for medical consultation, on the basis of the Service's records. If you are concerned about your sleep, talk to a doctor. The Company is not responsible for health decisions users make on the basis of the Service's records or their consequences.

(b) Detection and classification contain errors

• The Service treats sounds louder than the room's background noise (the baseline) by a set margin as events. Accordingly, the snoring or talking of a person sleeping next to you, pets, changes in the sound of fans, air conditioners, or humidifiers, outside noise, and rustling bedding may be recorded as your own sound, while quiet snoring or sleep talking may be masked by the baseline and not recorded. The Service does not distinguish whose sound it is.
• Sound classification uses the operating system's on-device sound analysis (iOS) or a public classification model bundled with the app (Android), and labels may differ from reality. Users can correct a Clip's label themselves, and the corrected label is reflected in that night's summary.
• Microphone performance and characteristics differ from device to device, and the phone's position, distance, and orientation, its case, and the operating system's automatic gain control affect detection results and sound-level values. The same night may produce different results on different devices.
• Sensitivity is set by the user and is reflected directly in detection results. The Company does not calibrate for, or guarantee results on, individual devices or environments.

(c) Overnight recording is subject to device and operating-system constraints

• Night recording keeps the microphone open for hours with the screen off. The operating system's power-saving policies, manufacturer battery optimization, insufficient storage, battery depletion, phone calls or other apps using the microphone, and operating-system updates may stop or interrupt recording midway, and the Company does not guarantee uninterrupted overnight recording. When an interruption is detected the app attempts to resume where possible and shows the number of interruptions in the morning summary.
• Night recording uses battery. Recording overnight without charging may leave the battery low in the morning. On Android the app explains how to exempt it from battery optimization, but the effect of that setting varies by device and manufacturer.
• Audio between events and the full night's audio are not stored. There are limits on the length of a Clip and on the number and size of Clips per night; once a limit is reached, further Clips for that night are not saved and only the count is recorded. New Clips are not saved when the device's free storage falls below a set level.
• On a night started with a Bedtime Sound, recording begins after the sound ends, so sounds during playback are not recorded.
• The wake-time setting is only the time at which recording stops; it is not an alarm. The Service does not wake you.

(d) Keeping and backing up your data is your responsibility

• Clips, Night Records, tags, and settings are stored only on your device, not on a Company server (Section 5), and are excluded from OS cloud backup and device transfer. Accordingly, the Company cannot recover data lost through device loss, reset, app deletion, or device replacement, and records do not move to a new device.
• In free use, Clip files are deleted automatically 30 days after the night they were recorded (favorites excluded). For owners of the Paid Product the default is unlimited, and it can be changed to 30 days. Favorite or export the Clips you need to keep, so that you hold them yourself.
• The possibility of data corruption from insufficient storage, operating-system policy changes, or unexpected errors during app updates cannot be entirely excluded.

(e) User responsibility for recording other people's sounds

• Sounds near the phone are recorded even if they are not yours. Users are responsible for informing anyone present in the space where recording takes place (such as a partner sleeping beside them) in advance, and for complying with the laws on recording, storage, and sharing in their country or region (including the Protection of Communications Secrets Act of Korea). Recording another person's conversation without their knowledge may be prohibited by law.
• The Company bears no legal liability arising from users' recording or from the storage, use, or provision of Clips.
• When you pass a Clip to a third party or make it public, you decide the recipients and scope and bear the resulting responsibility. The exported file's name includes the date and time the Clip was recorded.

(f) Bedtime Sounds

• Bedtime Sounds are background audio to listen to before sleep; they do not improve sleep or guarantee any particular effect.
• You control the playback volume. Listening at high volume or through earphones for long periods may affect your hearing, and managing that is your responsibility.
• Bedtime Sounds are provided only for playback within the app; there is no download, export, or sharing function (Section 7).

The Company is not responsible for the Service's records or for users' decisions or actions based on them and their consequences.

5. Modes of Use and Accounts

The Service is used without an account. There is no sign-up or login, and the Company does not create or keep an account identifying the user. Accordingly, no issues arise concerning the management of IDs and passwords or account theft.

All recordings and records handled by the Service are stored only on the user's device. The Company does not operate a server that receives users' recordings or records.

• Clips are stored as audio files in the app's private storage. The full night's audio is not stored; only the moments before and after a sound are saved, and sound classification also happens on the device.
• Night Records and tags are stored in the app's internal database.
• Settings (sensitivity, wake time, bedtime sound, retention, language, and so on) and Paid Product ownership status are stored in the device's app settings store.
• These storage areas are excluded from iOS and Android cloud backup and device transfer. Clips can be deleted one at a time in the app, and deleting the app deletes all of the above. Deleted data cannot be recovered, even by the Company.

Information leaving the device is limited to what is needed for usage statistics, error diagnostics, ads, and payments; the details and how to turn them off are set out in the Privacy Policy. Where a user passes a file to another app or third party through the clip export function, that transfer is made by the user's own choice and at the user's responsibility.

If the Company introduces account-based functions (backup, sync, and the like) in the future, it will announce the amendments to these Terms and the Privacy Policy in advance under the procedure in Section 2. Existing device data will not be sent to a Company server without the user's consent.

6. User Obligations and Prohibited Acts

Users must comply with applicable laws and these Terms and must not do any of the following.

• Use the recording function in situations prohibited by law, such as recording another person's conversation or sounds without informing them
• Use the Service to invade another person's privacy or to harass them
• Forge or alter Clips or records to deceive others or use them in a dispute
• Cause others to believe that the Service provides medical judgments or official measurement results
• Extract, copy, or distribute Bedtime Sound tracks outside the app, or reverse-engineer, copy, or modify the Service
• Obtain Paid Product benefits by improper means, or interfere with the normal operation of the Service or the advertising system using automated tools or otherwise
• Any other act contrary to applicable laws or these Terms

7. Rights and Responsibilities for Content

Clips, Night Records, and tags that users create with the Service belong to the user. The Company claims no rights in them and does not store or view them on its servers. Legal responsibility for their contents (Section 4(e)), however, rests with the user.

Intellectual property rights in the Service and its components (software, design, icons, text, the composition of the sound-classification model, and so on) belong to the Company or to the rights holders who have licensed them to the Company. Users are granted a non-exclusive right to use the Service for personal, non-commercial purposes; copying, distribution, or modification beyond that is not permitted without prior written consent.

Bedtime Sound tracks were either created by the Company or licensed from their rights holders for playback within the app. Users may use Bedtime Sounds only by playing them within the app; the app provides no function to download, export, share, or set them as ringtones. The clip export function applies only to Clips the user recorded. Extracting, copying, or distributing Bedtime Sound tracks by any means is not permitted.

The Service does not provide functions for posting content within the Service or exchanging it with other users. Accordingly, there are no report, block, or hide procedures for content between users. If the Company introduces such functions in the future, it will establish report-handling procedures and announce them in advance under the procedure in Section 2.

8. Advertising

• The Service is provided free of charge and displays Google AdMob ads to fund its operation. The current format is a banner ad at the bottom of the Morning summary screen and the History screen, which occupies space only when an ad is filled.
• No ads are shown while recording, while Bedtime Sounds play, or on the first-run onboarding screens. Interstitial ads, rewarded ads, and app-open ads are not used.
• The ad SDK starts when the History screen's banner placement becomes visible, not at app launch; at that point a region-dependent ad-consent prompt and the iOS tracking prompt may be shown. These prompts are not shown on the Morning summary screen right after a night.
• If you purchase the Paid Product, no ad placement in the app is displayed, and the screen space the ad occupied is reclaimed.
• The information collected by the ad SDK and your choices regarding personalized ads (consent management in the European Economic Area, the United Kingdom, and Switzerland; iOS App Tracking Transparency; Android advertising-ID settings) are set out in the Privacy Policy.

9. Paid Products, Payment, and Refunds

• The Service offers the following Paid Product.
  • Unlock all features — a non-consumable product applied permanently with a single purchase. After purchase you can view past Night Records without limit and use night-by-night and tag comparisons, choose unlimited Clip retention, use all Bedtime Sounds and "keep playing similar sounds", and no ads are shown. The specific benefits at the time of purchase are shown on the purchase screen.
• The seller of the Paid Product is the Apple App Store or Google Play. Payment is made under each store's policies and procedures, and the Company does not collect or store payment-instrument information such as card numbers. The price is the amount the store displays at the time of purchase.
• The Company may apply a different price for a limited period, such as around launch; the period and notice are shown on the purchase screen. The rights of users who have already completed a purchase are not affected by later price changes.
• Accordingly, refunds must be requested directly from the store where you purchased, and whether a refund is available and how long it takes are governed by that store's policy. The Company has no authority to process refunds on a user's behalf.
• Under Article 17 of the Act on the Consumer Protection in Electronic Commerce, etc. of Korea, users may in principle withdraw an offer within 7 days of purchase. However, under paragraph 2 of the same Article, withdrawal may be restricted for digital content that is fully provided immediately upon purchase once its provision has begun.
• If you change devices or reinstall the app, you can reapply Unlock all features with "Restore purchases" on the Settings or purchase screen. You must use the same App Store or Google Play account used for the purchase. Records and Clips are not restored (Section 4(d)).
• Where Unlock all features was applied with an offer code (App Store) or promo code (Google Play) distributed by the Company, its validity and restoration follow each store's code policies.
• Clips already deleted because their retention period expired are not revived by a purchase. Summary numbers for Clips deleted before purchase remain viewable.
• The Company will not reduce the scope of benefits provided to purchasers of Unlock all features. However, where unavoidable circumstances such as termination of the Service arise, it gives advance notice under the procedures in Sections 2 and 3.

The Company may change the types, prices, or composition of Paid Products or discontinue their sale. However, rights already acquired by users who have completed payment are not retroactively reduced or affected by such changes.

10. Restrictions on Use of the Service

If a user violates these Terms or applicable laws, the Company may restrict use of the Service to the extent permitted by applicable laws. Because the Service has no accounts, however, there is no means to identify an individual user and suspend their use; restrictions are implemented through discontinuation of the relevant function, measures through app updates, compliance with store distribution policies, and the like. Legal liability arising from unlawful use rests with the user.

Before taking a measure, the Company informs the user of the reason and duration and gives an opportunity to explain. However, where there are urgent grounds, such as serious infringement of others' rights or serious disruption of the Service's operation, the Company may act first and notify afterward.

Users may object to a measure through the contact point in Section 15, and if the objection is justified the Company lifts the measure without delay.

11. Termination of the Use Agreement

Users may end their use of the Service at any time by deleting the app. Because the Service has no accounts, there is no withdrawal application or notice to the Company, and the Company holds no user recordings or records that would need to be destroyed.

• Deleting the app deletes all Clips, Night Records, tags, and settings stored on the device, and no one, including the Company, can recover them. They are not included in OS backups either. Export the Clips you need to keep before deleting.
• A previously purchased Unlock all features can be revived by reinstalling the app with the same store account and using "Restore purchases". Deleting the app does not extinguish the purchase.
• Requests to delete usage statistics or error records already sent to external providers follow Section 8 of the Privacy Policy.

12. Personal Information Protection

The Company protects users' personal information in accordance with the Personal Information Protection Act of Korea and other applicable laws. Matters concerning the collection, use, provision, outsourcing, overseas transfer, retention period, and destruction of personal information are set out in a separate Privacy Policy.

The Service operates no accounts and does not send recordings, Clips, or Night Records to a server. Information leaving the device is limited to usage statistics and error diagnostics (which can be turned off in Settings), information needed to serve ads, and information needed to process payments. Details are available in the Privacy Policy.

13. Disclaimer

• The Company is not responsible for damage arising from the limits of the Service described in Section 4, in particular damage related to detection and classification errors, interrupted or missed recording, and health decisions based on the records.
• The Company is not responsible for decisions users make on the basis of information obtained through the Service or their consequences.
• The Company has no obligation to intervene in disputes between users and third parties (partners, family members, medical institutions, and so on).
• The Company bears no legal liability arising from users' recording or from the use or provision of Clips.
• The Company is not responsible for recording interruptions or data loss caused by circumstances of the user's device (insufficient storage, battery depletion, device loss or reset, operating-system or manufacturer power-saving policies, operating-system policy changes, and so on).
• The Company is exempt from liability where it cannot provide the Service due to force majeure such as natural disasters, power outages, communication failures, or failures of the operating system or external services (advertising, payment, analytics, and error-collection SDKs, app stores, and so on).
• The Company bears no responsibility in connection with the use of the Service provided free of charge unless applicable laws specifically provide otherwise. The Company's liability in connection with Paid Products is limited, to the extent permitted by applicable laws, to the amount paid by the user concerned.
• The limitations of liability in this section do not apply to damage caused by the Company's willful misconduct or gross negligence and do not limit the rights guaranteed to users by applicable laws.

14. Dispute Resolution and Jurisdiction

The laws of the Republic of Korea apply to the interpretation of these Terms and to disputes between the Company and users.

If a dispute arises in connection with the use of the Service, the Company and the user resolve it through consultation in accordance with the principle of good faith; lawsuits concerning disputes not resolved through consultation are filed with the court having jurisdiction under the Civil Procedure Act of Korea.

Before filing a lawsuit, users may apply for mediation to relevant bodies such as the Korea Consumer Agency's consumer counseling center or the Personal Information Dispute Mediation Committee.

However, where the user is a consumer residing outside the Republic of Korea, the rights guaranteed by the mandatory provisions of that country's law are not restricted.
