Terms of Service

Nexa Clip · Effective 2026-10-19 · Last updated 2026-10-12

Notice of revision — announced 2026-10-12 · effective 2026-10-19

These Terms have been revised to reflect the addition of file sharing between devices (v0.1.4) and license checking (v0.2.0). Main changes: the license section has been reorganized (Section 3 — free noncommercial use, commercial license files, offline checks); new provisions on received files (Section 5, items 5–8); a prohibition on forging or altering license files (Section 7); and a limitation of liability for harm caused by received files (Section 11). See the revision history at the bottom for details.

These Terms govern the rights, obligations, and responsibilities between SosomLab (the “Company”) and you regarding the use of Nexa Clip (the “Software”) and the relay server operated by the Company (the “Official Server”).

1. Definitions

  1. “Software” means the Nexa Clip application distributed by the Company, including the installer, portable, package-manager, and package-repository distributions and the helper program shipped with it (the isolated image decoder).
  2. “User” or “you” means anyone who downloads, installs, or uses the Software.
  3. “Relay Server” means the server program (nexa-beepd) that helps your devices on different networks meet each other. The Relay Server is not part of the Software; it is published separately from the Company’s Nexa Beep project.
  4. “Official Server” means the Relay Server operated by the Company at beepd.sosomlab.com and registered as the Software’s default.
  5. “Approved Device” means another device that you have approved in the Software’s device list after checking the comparison code.
  6. “Received File” means a file transferred from an Approved Device through the file-sharing feature (from v0.1.4) and saved on your device.
  7. “License File” means a file signed and issued by the Company to permit commercial use (from v0.2.0).

2. Effect and Changes

  1. These Terms take effect when you download, install, or use the Software.
  2. The Company may amend these Terms within the limits permitted by applicable law. Amendments and their effective date will be posted on this page; material changes will be announced at least 7 days before they take effect. Continued use of the Software after the effective date constitutes acceptance of the amended Terms.

3. License

  1. The Software is provided under the PolyForm Noncommercial License 1.0.0 (the “License Text”). Use for any noncommercial purpose as defined in the License Text — including personal use and use by charitable organizations, educational institutions, public research organizations, public safety or health organizations, environmental protection organizations, and government institutions — is free of charge and requires no License File.
  2. Commercial use requires a separate paid commercial license. Commercial licenses are issued as License Files signed by the Company. Enquiries and requests: [email protected].
  3. The scope of a commercial license (whether it is bound to particular devices, or granted per user, per seat, or per organization), its term (whether it has an expiry date, or is perpetual and applies to versions released up to a certain update date), and its fee are governed by the individual agreement between the Company and you and by what is stated in the issued License File. For versions released after a perpetual license’s update date, or once a license has expired, the Software shows the license as “outside its scope”; continued commercial use then requires renewal.
  4. License checks take place offline only, on your device; the Software sends no data to the Company for this purpose. In the current version, having or not having a License File makes no difference to the Software’s features; a License File is the means of confirming your right to commercial use.
  5. To request a device-bound license, you must send the Company the request code generated by the Software (which contains the device code and, if you enter them, your name and email address). How the Company handles this information is described in Section 2-3 of the Privacy Policy.
  6. Under the License Text, licenses may not be sublicensed or transferred to anyone else, and a commercial License File may not be used on devices or by users outside the scope for which it was issued.
  7. The full License Text is published in the Software’s source repository and prevails over this section in case of conflict. The Korean translation of the License Text is an unofficial translation provided for convenience; the English text is authoritative.
  8. The Software is licensed, not sold. All intellectual property rights, including copyright, remain with the Company.

4. Nature of the Software

  1. By default the Software operates entirely on your device. The Company provides no account, hosting, or storage service, and even with sync enabled, clipboard contents and files travel only between your own devices.
  2. The Software sends no personal data to the Company. What is stored on your device, what leaves it over the network, and what the Company receives when you request a license are described in the Privacy Policy.
  3. Synced clipboard items and files (paths and contents) are end-to-end encrypted between devices. The Company cannot access their contents by any route and therefore cannot recover, hand over, inspect, or moderate them.
  4. Your clipboard history is encrypted with the device key on your device (device.key), and your sync identity lives in the identity key (identity.key). If these files are damaged or deleted, the history can no longer be opened and other devices will see you as a new device; the Company has no way to restore them. Backing up your data folder is your responsibility. History is not kept anywhere outside your device and does not follow you to a new device.
  5. The pairing passphrase is the ingredient that prevents others from computing where your devices meet. Even if it leaks, nothing is exchanged with a device you have not approved, but managing the pairing passphrase and device approvals is your responsibility. A lost device should be revoked and deleted from the device list immediately.

5. Responsibility for Clipboard Contents and Received Files

  1. The Software records what you copy, as is. Passwords, authentication tokens, personal data, and third-party copyrighted material may pass through the clipboard, and you decide what is recorded, retained, and synced through the settings (excluded apps, retention policy, clear on exit, sync on/off, file sharing on/off, device approval).
  2. The Software respects the operating system’s conceal marker, but you should be aware that sensitive content copied from apps that do not send that marker may remain in your history.
  3. Items and files propagated to an Approved Device are stored in that device’s history and save folder. If you approve a shared device or someone else’s device, the consequences are your responsibility.
  4. You must not use the Software to store or propagate content that infringes the rights of others or is prohibited by applicable law.
  5. When you turn sync on, file sharing is on by default, and files of 50 MB or less may be transferred to and stored on your Approved Devices in advance even if you never paste them. If you do not want this, turn file sharing off or set the prefetch size to 0 in settings.
  6. Received Files are saved exactly as they were, without quarantine, malware scanning, or sanitization (executable files included). The Company cannot see or inspect Received Files and does not warrant that they are safe, undamaged, or identical to the originals. Checking a Received File before opening or running it is your responsibility, and responsibility for any malware in a Received File, or for the consequences of its contents, lies with the user who copied and propagated it and the user who opened or ran it.
  7. Received Files are stored as ordinary, unencrypted files and are not removed when you delete your history. Keeping, deleting, and protecting Received Files, and managing the storage space they use, is your responsibility.
  8. Because file contents are fetched from the source device at paste time, they cannot be retrieved if the source device is off or not connected, and if the original file is changed or deleted during transfer, the transfer may fail or only the path may be provided.

6. Official Server

  1. The Official Server is an optional feature the Company provides free of charge, as a courtesy, so that your devices on different networks can meet. It is used only if you select it in settings and run a connection test; with the relay set to None, the Software works fully on the same network without it.
  2. The Official Server only relays and stores neither clipboard contents, files, nor metadata. Consequently, sync and file transfers through the server occur only while both devices are connected at the same time.
  3. The Company does not guarantee the availability, response time, throughput, or continued provision of the Official Server. The Company may maintain, change, suspend, or shut down the server without prior notice and may impose or change abuse-prevention limits such as per-connection bandwidth caps, concurrent-channel limits, and idle timeouts. Exchanging large files through the server may be slow or may be interrupted.
  4. Suspension of the Official Server does not affect sync on the same network or any on-device feature. You may at any time run the Relay Server program yourself; a self-hosted server behaves identically to the Official Server.
  5. The Company accepts no responsibility for Relay Servers hosted by you or by third parties.

7. Your Obligations

You must not:

  1. use the Software commercially without a valid commercial license;
  2. forge or alter a License File, let it be used on devices or by users beyond the scope for which it was issued, or circumvent the license-checking mechanism;
  3. approve another person’s device without their consent, or obtain another person’s pairing passphrase to attempt to meet their devices;
  4. place excessive load on the Official Server, circumvent abuse-prevention measures such as bandwidth caps or connection limits, or attack the server;
  5. attempt to harm other people’s devices or data by circumventing the Software’s safeguards (encrypted storage, device approval, server pinning, and the like);
  6. store or propagate malware, pirated material, or content that infringes the rights of others or is prohibited by applicable law;
  7. engage in any other conduct prohibited by applicable law or these Terms.

The Company may block connections that abuse the Official Server without prior notice. Because the Company cannot see synced contents, it cannot intervene in or mediate disputes between users.

8. Pasting and Key Injection

  1. To paste the item you choose into the previously active window, the Software uses the operating system’s input-injection facilities (Windows SendInput, macOS Accessibility, Linux desktop portal). These work only after you grant permission, and which window receives the injected content depends on the focus at the moment of injection. The Software attempts to restore the original window but does not guarantee it; the consequences of content pasted into the wrong window are your responsibility. If receiving a file takes a while, the Software may place it on the clipboard without pasting it automatically.
  2. Injection may not work in apps running with administrator privileges, in some terminals, or in remote-desktop sessions. In such cases the content is on the clipboard and you must paste it yourself.

9. Third-Party Components

The Software runs on components provided by the operating system and may interoperate with third-party software (package managers, desktop environments, and the like). Those components are subject to their own licenses and terms.

10. Disclaimer of Warranties

The Software and the Official Server are provided “as is”, without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. The Company does not warrant that the Software will operate without interruption or error, or that it will be compatible with any particular network environment, hardware, system configuration, or desktop environment. In particular, clipboard monitoring, key injection, same-network discovery, or file transfer may not work on some Wayland compositors, guest Wi-Fi networks, or virtual-machine networks.

11. Limitation of Liability

To the maximum extent permitted by applicable law, the Company shall not be liable for any indirect, incidental, special, consequential, or punitive damages, for loss of data, profits, or business, for loss or corruption of clipboard history, for items or files that are not propagated, are delayed, are propagated incorrectly, or are transferred incompletely, for harm caused by malware in or the contents of Received Files, for losses caused by Received Files occupying storage space or being removed by automatic clean-up, or for harm caused by content pasted into the wrong window, arising from the use of or inability to use the Software or the Official Server. Liability that cannot be excluded by law, including liability for intent or gross negligence, is not limited.

12. Discontinuation

The Company may change or discontinue distribution of the Software or any of its features, and operation of the Official Server, at any time. Copies already installed may continue to be used under these Terms, and on-device features and same-network sync continue to work independently of the Official Server. Because license checks are performed offline, issued License Files remain valid within their scope regardless of any discontinuation of the Company’s services.

13. Governing Law and Jurisdiction

These Terms are governed by the laws of the Republic of Korea. Disputes arising in connection with the Software shall be brought before the court having jurisdiction under the Civil Procedure Act.
