Terms of Use

Effective: October 17, 2026

This is an English translation of the Korean Terms of Use. If they differ, the Korean version prevails.

Article 1 (Purpose)

These Terms set out the rights, obligations and responsibilities of Dumoni (the “Operator”) and users, and other necessary matters, regarding the use of the Dumoni service (the “Service”) provided by the Operator.

Article 2 (Definitions)

1. “Service” means all features that, through the iPad app “Dumoni” (the “App”) and the Windows program “Dumoni Agent” (the “Agent”), let an iPad be used as an extended display of a Windows computer and let mouse and keyboard input and the clipboard be shared between the two devices.
2. “User” means a person who uses the Service under these Terms.
3. “Free trial” means providing the Service without charge for a set period to a user using the App for the first time.
4. “Subscription” means paying recurring fees through the App Store and using the Service during that period.

Article 3 (Posting and Amendment of the Terms)

1. The Operator posts these Terms in the App and on the website (dumoni.app).
2. The Operator may amend these Terms to the extent that doing so does not violate applicable laws, including the Korean Act on the Regulation of Terms and Conditions.
3. When amending these Terms, the Operator announces the effective date and the reason in the App or on the website from 7 days before the effective date, or from 30 days before for changes unfavorable to users.
4. A user who keeps using the Service after the effective date is deemed to have agreed to the amended Terms. A user who does not agree may stop using the Service and cancel the subscription.

Article 4 (What the Service Provides and Requirements)

1. The Service provides the following features:
   1. Using an iPad as an extended display of a Windows computer
   2. Controlling an iPad with the Windows computer’s mouse and keyboard
   3. Exchanging copied text and photos between the two devices
2. To use the Service, the Agent must be installed and running on the Windows computer. The App alone cannot provide the Service.
3. The Agent runs on Windows 10 version 2004 or later. The App runs on the iPadOS versions shown on the App Store.
4. The Service works over Bluetooth and direct connections between the two devices. The extended display and sending photos or long text require both devices to be on the same network, and may not work on networks that restrict communication between devices.
5. The Agent installs a virtual display driver for the extended display and the components it needs (firewall rules, scheduled tasks and the like), and asks for administrator permission when installing them.
6. When a new version of the Agent is available, the Agent downloads it and applies it from the next launch.

Article 5 (Free Trial and Subscription)

1. Users can use a 7-day free trial when they first use the App. No fee is charged during the free trial.
2. To keep using the Service after the free trial, a subscription is required. Without a subscription, the Service’s features are limited.
3. Subscription fees and benefits such as first-subscription discounts follow what is shown on the App’s purchase screen. Amounts may differ by country and currency.
4. Subscription payments are made through Apple Inc.’s App Store.
5. The subscription renews automatically every month, and the next period is charged unless it is cancelled at least 24 hours before the current period ends.

Article 6 (Cancellation and Refunds)

1. Users can cancel at any time in Settings > Apple Account > Subscriptions on the iPad. Deleting the App does not cancel the subscription.
2. After cancelling, the Service remains available until the end of the period already paid for.
3. Payments and refunds are handled by Apple under Apple’s policies. Refunds can be requested from Apple (reportaproblem.apple.com).
4. The Operator does not receive payments directly and therefore does not issue refunds directly. Withdrawal of subscription and similar rights under applicable law are handled through Apple’s procedures.

Article 7 (Prohibited Conduct)

1. Users must not:
   1. Install or use the Service on another person’s computer or iPad without that person’s consent;
   2. Reverse engineer, decompile or disassemble the App, the Agent or the communication between them, or try to learn the Service’s structure, protocol, algorithms or source code by packet or memory analysis or similar methods;
   3. Use the Service, or information obtained under item (b), to make software with the same or substantially similar features, including by feeding the Service’s screens, behavior, code or communication into artificial intelligence tools to have them reproduce it;
   4. Connect programs not provided by the Operator to the Agent or the App, or call the Service’s features in ways not provided by the Operator;
   5. Bypass, alter or disable the features that check subscription, free trial or other conditions of use, or tell others how to do so;
   6. Distribute, sell, rent, share or post the Service, modified versions of it, or the software described in item (c), whether for a fee or not;
   7. Use the names “Dumoni” or “듀모니”, the logo, the character, the screen design, or marks that could be confused with them, without the Operator’s permission;
   8. Use the Service to violate laws or infringe the rights of others.
2. Having others do the conduct in paragraph 1, or helping others do it, is also prohibited.
3. Items (b) through (f) of paragraph 1 do not apply to conduct expressly permitted by applicable law.

Article 7-2 (Measures Against Violations)

1. If a user violates Article 7, the Operator may restrict or suspend the user’s use of the Service. The Operator gives notice in advance, but may give notice afterwards when urgent action is needed to prevent damage from the violation.
2. For software and posts made or distributed in violation of Article 7, the Operator may demand that distribution stop and that they be deleted, and may ask app marketplaces such as the App Store, hosting providers, search providers and others to delete or block them.
3. A user who violates Article 7 must compensate the Operator for the resulting damage, including reasonable costs of investigating and responding to the violation. Damages may be calculated as provided by applicable laws such as the Korean Copyright Act and the Unfair Competition Prevention and Trade Secret Protection Act.
4. The Operator may take civil and criminal legal action under applicable law against violations of Article 7.

Article 8 (Changes to and Discontinuation of the Service)

1. The Operator may add or change features of the Service.
2. If the Operator ends the Service, it announces this in the App and on the website at least 30 days before the end date.
3. The Service may temporarily not work because of the user’s device, operating system or network, or because of third-party services such as Apple.

Article 9 (Limitation of Liability)

1. The Operator provides the Service as is and does not guarantee that it works on every device and in every environment.
2. The Operator is not liable for damage that occurs without the Operator’s fault, such as natural disasters, problems with the user’s device, operating system or network, or failures of third-party services.
3. Even where the Operator is liable, unless there is intent or gross negligence on the Operator’s part, the Operator’s liability is limited to the subscription fee the user paid for the month in which the damage occurred.

Article 10 (Intellectual Property and License)

1. Copyright and other intellectual property rights in the Service belong to the Operator. Users have a non-exclusive right to use the Service under these Terms.
2. The license for the App is governed by these Terms together with Apple’s standard Licensed Application End User License Agreement. If they differ, these Terms prevail.
3. The Agent may be used only to use the Service together with the App the Operator provides through the App Store.
4. No rights in the Service are granted to users other than those expressly granted in these Terms, and the right of use in paragraph 1 ends if the user violates Article 7.

Article 11 (Privacy)

How the Operator handles personal information is governed by the Privacy Policy.

Article 12 (Governing Law and Jurisdiction)

1. These Terms are governed by the laws of the Republic of Korea.
2. Disputes between the Operator and a user about the use of the Service are brought before the court with jurisdiction under the Korean Civil Procedure Act.
