CaptionLab — End User License Agreement (EULA)
================================================

Version 1.0.6  ·  Last updated 28 August 2026
Copyright © 2026 Edit Lab Tools. All rights reserved.

By installing or using CaptionLab ("the Software"), you agree to the
following terms:


1. LICENSE GRANT
   Edit Lab Tools grants you a non-exclusive, non-transferable license to use
   the Software on Mac or Windows computers personally owned or controlled
   by you.

   This is a single-user license:
   • One person — multiple computers (your laptop + your desktop is fine)
   • Not for sharing with friends, colleagues, or teams

   SITE AND EDUCATION LICENSES
   A site license, issued as a key in the form CL-EDU-XXXX-XXXX-XXXX, covers
   an agreed number of computers within one institution. Under a site license:
   • The seat is held by the COMPUTER, not by a person. Any number of people
     may use a licensed computer.
   • The key may be used only on computers belonging to the institution named
     in the purchase, and may not be redistributed outside it.
   • Seats may be moved between computers by contacting us.

   For team, site or education licenses, contact editlabtools@gmail.com.


2. RESTRICTIONS
   You may NOT:
   • Resell, redistribute, or share the installer files
   • Reverse engineer, decompile, or disassemble the Software
   • Remove or alter any copyright notices or branding
   • Use the Software to build a competing product


3. OWNERSHIP
   The CaptionLab platform, brand, and codebase — and all intellectual
   property rights in the Software — remain the exclusive property of
   Edit Lab Tools. This license does not transfer ownership, and none of
   it may be copied, reproduced, or redistributed without permission.


3a. YOUR CONTENT
    You retain full ownership of your footage, audio, transcripts, and
    any other content you process with the Software. Edit Lab Tools does
    not claim ownership over your files or the subtitles CaptionLab
    generates for you, and — since all processing happens locally on
    your own computer — never receives or has access to that content
    in the first place.


4. THIRD-PARTY COMPONENTS
   CaptionLab uses the following open-source components, distributed
   under their respective licenses:

   • OpenAI Whisper          — MIT License
   • faster-whisper          — MIT License
   • Flask                   — BSD License
   • ffmpeg                  — LGPL / GPL
   • Python                  — PSF License
   • Adobe CSInterface.js    — Adobe license (included for CEP support)

   macOS only:
   • mlx-whisper             — MIT License (Apple Silicon Macs only)

   Windows only:
   • nvidia-cublas-cu12      — NVIDIA proprietary redistributable license
   • nvidia-cudnn-cu12       — NVIDIA proprietary redistributable license
     (installed only if an NVIDIA GPU is detected, to accelerate
     transcription; not open-source, not required on CPU-only systems)

   Whisper AI models are downloaded from HuggingFace at first launch
   and are subject to their original license (MIT).


5. PRIVACY
   CaptionLab processes all audio locally on your computer. No audio,
   transcripts, project data or file names are transmitted to Edit Lab Tools
   or any third party.

   The only network requests made are:
   • One-time download of the Python runtime, ffmpeg, the Whisper AI model,
     and — on Windows with an NVIDIA card — the CUDA runtime libraries, from
     public sources at first launch.
   • Periodic license verification, which sends a randomly generated machine
     identifier together with the computer name, operating system version and
     Premiere Pro version. The identifier is derived from nothing about your
     hardware and means nothing outside our license server.
   • Optional additional AI models, only if you choose to download them.

6. WARRANTY DISCLAIMER
   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.


7. LIMITATION OF LIABILITY
   IN NO EVENT SHALL EDITLAB BE LIABLE FOR ANY CLAIM, DAMAGES, OR
   OTHER LIABILITY ARISING FROM THE USE OF OR INABILITY TO USE
   THE SOFTWARE.


8. REFUND POLICY
   Refunds are available within 14 days of purchase, no questions
   asked. Email editlabtools@gmail.com with your order number.

   See full policy: https://captionlab.pro/#refund


9. UPDATES
   You are entitled to all minor updates (1.x) for the version you
   purchased. Major version upgrades may require an additional fee.


10. TERMINATION
    This license is effective until terminated. Edit Lab Tools may terminate
    it if you breach any term. Upon termination, you must uninstall
    and delete all copies of the Software.


11. GOVERNING LAW
    This agreement is governed by the laws of Ukraine. Disputes shall
    be resolved through good-faith negotiation first; failing that,
    through the courts of Ukraine.
