By downloading, installing, or using ProEnd Editor ("the Software"), you agree to be bound by these Terms of Service. If you do not agree to all of these terms, you must not use the Software.
Subject to your compliance with these Terms, you are granted a limited, non-exclusive, non-transferable, revocable license to use ProEnd Editor solely for your personal or internal business purposes.
You agree to use ProEnd Editor only for lawful purposes. You must not use the Software to:
You retain all rights to the video files and media you process. The Software processes files locally on your machine. You are solely responsible for ensuring you have the necessary rights to process any media you use with the Software.
The Software is provided "as is" and "as available" without any warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability or fitness for a particular purpose.
To the maximum extent permitted by applicable law, ProEnd Editor and its developers shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, loss of profits, or business interruption, arising out of your use of the Software.
We reserve the right to modify these Terms at any time. Continued use of the Software after modifications constitutes your acceptance of the revised Terms.
These Terms shall be governed by and construed in accordance with applicable law. Any disputes shall be resolved through binding arbitration or a court of competent jurisdiction.
We reserve the right to terminate your license at any time if you violate these Terms. Upon termination, you must cease all use of the Software and destroy any copies in your possession.
ProEnd Editor takes your privacy seriously. This Privacy Policy explains what information the Software does and does not collect, how it is used, and your rights regarding that information.
ProEnd Editor does not collect, transmit, or store:
All editing operations are performed entirely on your local machine using FFmpeg. Processed files are saved to your local filesystem only.
The backend server may log basic technical information locally (API request paths, error messages) for debugging. This information stays on your machine and is never transmitted externally.
When you accept these policies, ProEnd Editor stores a small consent record in your browser's localStorage — a storage area that lives entirely on your own device and is never transmitted to any server. This record contains:
This record exists solely so the agreement screen is not shown again on subsequent visits. It contains no personal information, no account identifiers, and no usage data. You can clear it at any time by clearing your browser's site data or localStorage.
The Software's frontend loads the Poppins and JetBrains Mono typefaces from Google Fonts via CDN requests. These are subject to Google's privacy policy. No personal data or file content is included in these requests. Beyond font resources, ProEnd Editor integrates with no third-party analytics, advertising, or tracking services.
Since ProEnd Editor does not collect or transmit personal data, the primary data security responsibility lies with you — securing your own device and filesystem where processed videos are stored.
Since we do not collect personal data, there is no personal data held by us to access, correct, or delete. All files remain entirely under your control on your local machine. You may clear the localStorage consent record at any time via your browser's site data settings, which will cause the agreement screen to be shown again on your next visit.
We may update this Privacy Policy from time to time. When we do, the policy version key stored in localStorage will be incremented (e.g. from proend_legal_v1 to proend_legal_v2), and you will be required to review and accept the updated policies before continuing to use the Software.
