Keymate Terms of Service

Effective date: 2026-05-18

Article 1 (Purpose)

These Terms govern the rights, obligations and responsibilities between Nemo Studio (Representative: Wangjun Cha; Business Reg. No. 482-06-03410; Mail-Order Sales Reg. No. 2025-Changwon Seongsan-0574; Address: 774 Wonidae-ro, Seongsan-gu, Changwon-si, Gyeongsangnam-do, Republic of Korea; "the Company") and users with respect to use of the Keymate mobile and desktop applications (the "Service").

Article 2 (Definitions)

  • "Service" means all applications provided by the Company that enable a phone to be used as a secondary input device for a PC.
  • "User" means any person who uses the Service under these Terms.
  • "Pairing" means connecting a phone and a PC on the same local network so they can communicate with each other.
  • "License" means a paid-feature activation key issued by the Company.

Article 3 (Effectiveness and Modification)

  • These Terms apply to all users who wish to use the Service.
  • The Company may amend these Terms when necessary, provided the amendment does not violate applicable laws.
  • When the Terms are amended, the Company will give notice through in-app announcement or on this page at least 7 days before the effective date. If the amendment is unfavorable to users, notice will be given at least 30 days in advance.

Article 4 (Provision of the Service)

  • The Company provides, among others, the following functions: using a phone as an input controller for a PC; editing button layouts and configuring actions such as hotkeys, URLs and app launches; QR-code-based pairing and local-network connection; and any other functions the Company makes available via the in-app UI or separate notices.
  • The Service may consist of free features and paid features activated by a license key. The scope, price and payment method for paid features will be posted in the app or on a page separately announced by the Company.
  • The desktop application requires macOS Accessibility permission in order to simulate keyboard, mouse and media keys. This permission is used solely to execute the button actions configured by the user; it is not used to record or transmit screen contents.
  • The desktop application may periodically contact the update endpoint operated by the Company to check for new versions for security and feature updates, and may download and install updates after notifying the user.

Article 5 (Account and Registration)

The Service is available without a separate account or registration process. Pairing information, button layouts and other data necessary for using the Service are, in principle, stored on the user's device or paired PC. Any information separately collected by the Company for inquiry handling, license verification or service improvement is processed in accordance with the Privacy Policy.

Article 6 (Use by Minors)

Minors purchasing or using paid features may require the consent of their legal representative. Paid transactions made by minors without such consent may be cancelled in accordance with applicable laws.

Article 7 (User Obligations)

Users must not engage in any of the following:

  • Reverse engineering, decompiling or disassembling the Service or the Company's systems, except where permitted by applicable law
  • Unauthorized copying, distribution, transfer or resale of license keys
  • Using the Service to infringe the rights of others or to violate applicable laws
  • Any act that interferes with normal operation of the Service
  • Infringing the intellectual property rights of the Company or any third party

Article 8 (Intellectual Property)

  • All intellectual property rights in the software, design, trademarks, logos and other materials included in the Service belong to the Company or its lawful right-holders.
  • Configuration data such as button layouts created by the user within the Service belongs to the user. If the Company transmits or stores such data externally, it will disclose the details in the Privacy Policy or via a separate notice.

Article 9 (Paid Features, Payment and Refunds)

  • Paid features are activated by entering a license key.
  • Payments are processed through the payment processor Polar Software Inc. (Merchant of Record). Receipts, taxes and other matters directly related to payment are governed by the payment processor's policies.
  • A paid license is a non-exclusive, non-transferable right granted to a single user and may be activated on up to two PCs used by the same user. Unauthorized copying, distribution, transfer or resale of license keys is prohibited.
  • Pursuant to Article 17 of the Korean Act on the Consumer Protection in Electronic Commerce, users may withdraw their subscription within 7 days of the payment date. However, where the right of withdrawal is restricted (e.g., where divisible digital content has been provided as set out in Article 17(2)(5) of the same Act), withdrawal may be restricted to that extent, and the Company will give advance notice of any such restriction at the payment or license-activation stage.
  • Except where withdrawal is restricted under the preceding paragraph, the Company will accept refund requests submitted within 7 days of purchase from users who have not activated the license, for payments made directly to the Company.
  • Where the Service is provided differently from its advertised or contractual contents, refunds or withdrawal will be governed by applicable laws regardless of whether the license has been activated.
  • Where a refund is approved, the Company or the payment processor will initiate the refund procedure within 3 business days of confirming the reason. The actual completion time may vary depending on the payment method and the procedures of the relevant financial institution.
  • If a user loses a license key, the Company may, after verifying the purchase record, support reissuance or recovery. Where recovery is impossible due to the user's own fault — such as unauthorized transfer or resale of the license key — refunds or reissuance may be restricted.

Article 10 (Changes and Discontinuation of the Service)

  • The Company may change or discontinue all or part of the Service for operational or technical reasons.
  • Provision of the Service may be temporarily interrupted due to circumstances beyond the Company's control, such as natural disasters, communication failures or operating-system policy changes.
  • For material changes or discontinuation, the Company will notify users a reasonable time in advance.

Article 11 (Termination)

Users may terminate the Service agreement at any time by uninstalling the app, in which case data stored on the device may be deleted. Button layouts, pairing info and license data stored on the PC may need to be removed separately by the user through the desktop app or the operating-system's uninstall flow.

Article 12 (Disclaimer)

  • Because the Service depends on the user's local Wi-Fi environment, the Company is not liable for pairing failures or communication delays caused by router settings, firewalls, communication failures or similar issues, in the absence of intent or gross negligence by the Company.
  • The Service operates on the assumption that operating-system permissions (e.g., macOS Accessibility) are granted. The Company is not liable for limitations caused by the user denying such permissions or by an operating-system policy change that revokes them, in the absence of intent or gross negligence by the Company.
  • The user is responsible for any actions performed on the PC through the keyboard/mouse simulation feature, and for the consequences thereof (e.g., file corruption, data loss).
  • Unless otherwise specifically required by applicable law, the Company is not liable for any matters related to use of features provided free of charge.

Article 13 (Privacy)

The collection and processing of personal data is governed by the separate Privacy Policy.

Article 14 (Governing Law and Jurisdiction)

  • These Terms and any dispute between the Company and a user shall be governed by the laws of the Republic of Korea. However, where the user is a consumer, this clause applies only to the extent that it does not contravene mandatory provisions of the user's place of residence.
  • The court of first instance with jurisdiction under the Korean Civil Procedure Act shall be the competent court for disputes arising in connection with use of the Service.
