End User License Agreement

Last updated: April 2026

1. License Grant

NK Productions grants you a non-exclusive, non-transferable license to use the software product (the “Software”) on up to three (3) computers owned or controlled by you.

2. License Activation

The Software requires license activation. A valid license key must be entered to unlock the full version. Each license key may be activated on up to three (3) machines. License deactivation and reactivation can be managed through the Software’s settings menu. Offline activation is also available for computers without internet access via the Offline Activation page. Once activated online, the Software operates offline for 90 days. If no internet access is detected after 90 days, a 90-day grace period begins. After a total of 6 months offline, reactivation is required. Offline-activated licenses do not require periodic internet access. The license itself is perpetual.

3. Trial Version

The Software may be used in trial mode without a license key. Trial mode is fully functional but periodically injects noise bursts into the audio output.

4. Restrictions

You may not:

  • Copy, distribute, or share the Software or license key with third parties
  • Reverse engineer, decompile, or disassemble the Software
  • Modify, adapt, or create derivative works based on the Software
  • Remove or alter any proprietary notices, labels, or marks on the Software
  • Resell, rent, lease, or sublicense the Software or license key

5. Intellectual Property

The Software, including all neural network models, signal processing algorithms, and user interface designs, is the intellectual property of NK Productions. This license does not grant you any ownership rights to the Software.

6. Data Collection

The Software collects the following data for license activation and validation purposes only:

  • Machine identifier (hardware-derived, anonymized)
  • License key

No personal information, audio data, or usage analytics are collected or transmitted.

Offline activation can be completed without any internet connection. The activation process itself does not involve any network communication — simply enter a response code obtained from a separate device. With offline activation, no periodic server communication of any kind is performed, and no data of any kind is collected or transmitted from the Software.

7. Refund Policy

As this is a digital product, all sales are final. No refunds will be issued after the license key has been delivered. We strongly recommend evaluating the trial version before purchase to ensure compatibility with your system and workflow.

8. Disclaimer of Warranties

The Software is provided “as is” without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and non-infringement. NK Productions does not warrant that the Software will be error-free or uninterrupted.

9. Limitation of Liability

In no event shall NK Productions be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or in connection with the use of the Software, regardless of the cause of action. NK Productions’ total liability shall not exceed the amount paid by you for the Software license.

10. Termination

This license is effective until terminated. NK Productions may terminate this license if you fail to comply with any of its terms. Upon termination, you must destroy all copies of the Software in your possession.

11. Governing Law

This agreement shall be governed by and construed in accordance with the laws of Japan. Any disputes arising from this agreement shall be subject to the exclusive jurisdiction of the courts of Japan.
