Terms of Service

Article 1 (Purpose; Changes to the Terms)

(1) These Terms define the rights, obligations and responsibilities between the Company and users in connection with the Service.

(2) The Company may amend these Terms to the extent permitted by applicable law. Amendments are announced on this page and in the app, with the effective date and the changes, at least 7 days before they take effect; amendments unfavorable to users are announced at least 30 days in advance. Continued use after an announcement constitutes agreement. Users who do not agree may stop using the Service and delete their account.

(3) Questions about these Terms may be sent to huurray@gmail.com or through Settings → Contact in the app.

Article 2 (Definitions)

• "Service" means the mobile application "Murmur" and all associated services provided by the Company.
• "User" means anyone who uses the Service under these Terms.
• "Entry" or "journal" means any voice, photo or text a user records, attaches or stores in the Service.
• "AI features" means features that analyze entries for emotion, summary, keywords and voice tone, and that generate companion replies, monthly reports, memoirs and letters.
• "Premium" means the auto-renewing subscription described in Article 6.

Article 3 (Nature of the Service)

(1) The Service is a personal voice journal that lets you record your day by voice and reflect on your feelings with the help of AI features. Entries are never shown to other users, and share cards you create yourself never contain journal content.

(2) The Service is developed and released in the Republic of Korea.

(3) The Company may improve or change the Service and does not guarantee that any particular feature will always be provided in the same form. Material changes are announced under Article 13.

Article 4 (Accounts)

(1) Using the Service requires an email account or Google or Apple sign-in. Information you register must be accurate, and you may not use another person’s information.

(2) You are responsible for your account, password and app-lock PIN. Notify the Company immediately if you suspect unauthorized use of your account.

(3) Children under 14 may not sign up. Minors need the consent of a legal guardian to pay for paid features; payments made without such consent may be cancelled under applicable law.

(4) You may delete your account at any time in the app under Settings → Account → Delete account. Entries and personal information stored on the server are then deleted under the Privacy Policy. An active subscription must be cancelled separately in the store.

Article 5 (Usage Limits)

(1) The following limits apply to the free plan and to Premium. They are set for service stability and cost, and changes are announced under Article 1 (2).

(2) Free AI uses reset on the first day of each month and do not carry over. You choose which entries to use them on.

Article 6 (Premium Subscription)

(1) The Company offers "Premium", an auto-renewing subscription, in monthly and yearly plans. The price is KRW 3,900 per month or KRW 39,000 per year; the actual currency and amount may differ depending on your store (Apple App Store / Google Play) country and taxes. The exact price is shown on the purchase screen.

(2) Unless cancelled, the subscription renews automatically at the end of each period on the same terms, and the renewal fee is charged to the payment method registered with the store within 24 hours before the period ends.

(3) You can cancel in your store’s subscription settings (iOS: Settings → Apple Account → Subscriptions / Android: Google Play → Subscriptions). Cancelling at least 24 hours before the current period ends prevents the next charge, and benefits continue until the paid period ends. Deleting the app does not cancel the subscription.

(4) New users automatically receive a 7-day free trial on sign-up. The trial is granted once per account, starts without registering a payment method, and converts to the free plan at no charge when it ends. If you start a paid subscription during the trial, the remaining trial period is forfeited.

(5) When the subscription expires, automatic backup stops, but entries backed up while subscribed remain downloadable at any time. AI analyses, replies and memoirs created while subscribed remain viewable after expiry.

(6) Users who purchased the legacy one-time "Remove Ads" product keep the ad-free benefit independently of any subscription.

(7) The Company may change the contents or price of the subscription. Changes unfavorable to users are announced in the app at least 30 days before they take effect. New prices apply from the next renewal, and users who do not agree may cancel.

Article 7 (Payment and Refunds)

(1) Payments are processed by Apple or Google; the Company does not store payment-method details such as card numbers.

(2) Refunds follow the refund policies and procedures of each store (iOS: reportaproblem.apple.com / Android: Google Play Help). The Company may be unable to process refunds outside the store, in which case it will guide you to the store’s support.

(3) Under the Korean Act on Consumer Protection in Electronic Commerce, you may withdraw your subscription within 7 days of payment. Withdrawal may be limited to the extent permitted by law if you have already used Premium features.

(4) If Premium features were unavailable for a period due to the Company’s fault, the Company will extend the subscription by that period or provide reasonable compensation.

Article 8 (Advertising)

(1) Free-plan users may see interstitial ads provided by a third party (Google AdMob) at certain points, such as after saving a recording. Ads are not shown to active Premium subscribers or to purchasers of the ad-removal product in Article 6 (6).

(2) Use of the advertising identifier and tracking consent are governed by Section 9 of the Privacy Policy. To the extent permitted by law, the Company is not responsible for transactions or disputes between advertisers and users.

Article 9 (Storage, Backup and Loss of Entries)

(1) Recordings are stored only on your device by default. Recordings and photos created while Premium (including the free trial) is active are backed up automatically to the Company’s cloud; recordings created on the free plan are not backed up.

(2) Entries that are not backed up cannot be recovered if the device is lost, damaged or reset, if the app is deleted, or if you switch devices. The Company is not liable for the loss of entries that existed only on your device. You can keep entries outside the device with the export feature under Settings → Account.

(3) Backed-up entries are restored when you sign in to your account again. The Company takes reasonable measures to protect backup data, but to the extent permitted by law is not liable for loss caused by events beyond its control, such as natural disasters or outages of third-party services.

Article 10 (Your Entries and Prohibited Conduct)

(1) You own, and are responsible for, the entries you record, attach or store in the Service. The Company uses entries only to the extent needed to store, back up, AI-process and display them, and does not use or disclose them for any other purpose.

(2) You may not use the Service to:

• record, store or distribute another person’s personal information, copyrighted work or secrets without authorization
• exploit vulnerabilities in the Service or abuse AI features or APIs through automated means
• reverse-engineer or copy the Service, or use it commercially without the Company’s prior written consent
• violate applicable law or public order and morals

(3) The Company does not pre-screen your entries. Where a violation of law is evident or a lawful request is received from a competent authority, the Company may act in accordance with applicable law.

Article 11 (AI Features)

(1) AI features are processed by Google’s generative AI models, and their outputs (emotion, summary, keywords, voice tone, replies, memoirs, letters) are for reference only. Outputs may be inaccurate or differ from your intent, and the Company does not guarantee their accuracy or completeness.

(2) AI features do not replace professional advice such as medical, psychological or legal counseling. In an emotional crisis, please seek help from a professional organization.

(3) The scope of data sent for AI processing and the processor are set out in Section 4 of the Privacy Policy. The Company does not use your entries to train AI models.

Article 12 (Intellectual Property)

(1) Rights in the Service itself (design, logos, text, graphics, software, etc., excluding your entries) belong to the Company or its rightful licensors and are protected by applicable law.

(2) You may use the Service only for personal, non-commercial purposes and may not copy, distribute, modify or create derivative works from its components without the Company’s prior written consent.

Article 13 (Changes to or Discontinuation of the Service)

(1) The Company may modify or discontinue all or part of the Service for reasons such as improvement, changes in technical specifications, or policy changes by third-party services.

(2) Material changes or discontinuation are announced at least 30 days in advance in the app or by email to the registered address. Where unavoidable, such as urgent maintenance or security issues, notice may be given afterward.

(3) If the Service is discontinued entirely, the Company will provide a period during which you can download your entries and will reasonably compensate or refund paid subscribers for the unused subscription period.

Article 14 (Restriction of Use; Termination)

(1) If a user violates these Terms or applicable law, the Company may restrict use of the Service or terminate the agreement after notice (or, in urgent cases, with subsequent notice). Notice is given to the email address registered at sign-up or by similar means.

(2) If the Company terminates the agreement because of a user’s violation, refunds for already-paid periods are handled to the extent permitted by applicable law and each store’s policy.

Article 15 (Limitation of Liability; Disclaimer of Warranties)

(1) To the maximum extent permitted by applicable law, the Company is not liable for direct, indirect, special or consequential damages arising from or related to:

• use of or inability to use the Service
• loss of entries that were not backed up (Article 9)
• inaccuracy of AI outputs or decisions you make based on them (Article 11)
• alteration or disclosure of information through unauthorized third-party access, absent the Company’s intent or negligence
• outages or policy changes of third-party services (stores, cloud, AI, advertising)

(2) The Service is provided "as is". The Company does not warrant that the Service will be uninterrupted, error-free, or suited to your particular needs.

(3) Nothing in this Article excludes or limits liability for damages caused by the Company’s intent or gross negligence, for death or personal injury, or for any liability that cannot be excluded or limited by law.

Article 16 (Governing Law; Jurisdiction)

These Terms are governed by the laws of the Republic of Korea. Disputes between the Company and users in connection with the Service are first resolved through good-faith consultation; if that fails, the competent court is determined under the Korean Civil Procedure Act.
