Effective date: 2026-06-01

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.
  • "Paid plan" means the right to use paid features (monthly subscription or lifetime plan) purchasable through in-app purchases in the mobile app.

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 (Pro) activated through in-app purchases in the mobile app. 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, purchase-record 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 sharing, transfer or resale of accounts or paid plans
  • 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 (Pro) are activated through in-app purchases in the mobile app. The paid plans consist of a monthly subscription (USD 2.99) and a lifetime plan (USD 16.99). Prices may vary depending on app-store policies or exchange rates.
  • Payments are processed through the in-app purchase systems of the Apple App Store or Google Play Store. Collection and management of payment-method information, receipts, and tax handling are governed by the respective store's policies.
  • Monthly subscriptions renew automatically each month unless cancelled by the user. Subscriptions can be cancelled at any time via the subscription management menu in the Apple App Store or Google Play Store. Upon cancellation, paid features remain available until the end of the current billing period.
  • Refunds are subject to the refund policies of Apple or Google. Users may request refunds through the respective store's customer support. However, Korean users are guaranteed the right of withdrawal under the Korean Act on the Consumer Protection in Electronic Commerce, and applicable laws take precedence over store policies.
  • The right to use paid features is linked to the user's Apple ID or Google account and is available on devices signed in with the same account.

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 and pairing info 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.
