Terms of Service

Last updated: May 2026

1. Acceptance of Terms

By using SyncFlow, you agree to these Terms of Service. If you do not agree, do not use the tool.

2. Description of Service

SyncFlow is a free, client-side web application that allows users to synchronize subtitle files with video content. AI transcription sends audio through a secure Cloudflare proxy to Groq's Whisper-large-v3-turbo API. Audio data is processed in memory and never stored on any server. All local file processing occurs in the user's browser. No video or subtitle files are uploaded to any server.

3. No Warranty

SyncFlow is provided "as is" without any warranty, express or implied. AI transcription accuracy is not guaranteed — verify important transcriptions manually. We do not guarantee that:

• The tool will meet your specific requirements
• The tool will be uninterrupted, timely, or error-free
• Subtitle timing adjustments will be perfectly accurate
• Exported subtitle files will be compatible with all players

4. Limitation of Liability

In no event shall SyncFlow or its creators be liable for any damages arising from the use or inability to use this tool, including but not limited to loss of data, loss of time spent adjusting subtitles, or corrupted subtitle files.

5. User Responsibility

You are solely responsible for:

• The video and subtitle files you use with this tool
• Audio content used with the auto-transcribe feature
• Ensuring you have the legal right to modify any subtitle files
• Verifying the accuracy of exported subtitle timings
• Complying with applicable copyright laws regarding video content

6. Intellectual Property

SyncFlow's source code is available on GitHub. The tool name, logo, and branding are provided as-is. You may not use SyncFlow's branding to imply endorsement of third-party products.

7. Beta Features

Some features (auto-transcribe, waveform preview) are provided as beta. They may change, have bugs, or be removed.

8. Privacy & Analytics

SyncFlow does not require account creation. We use Google Analytics to collect anonymous usage data (page views, feature interactions) to help improve the tool. No personal information is collected, and video or subtitle file contents are never transmitted to analytics servers. See our Privacy Policy and Cookie Policy for details.

9. Changes to Terms

We reserve the right to update these terms at any time. Continued use of SyncFlow after changes constitutes acceptance of the new terms.

10. Governing Law

These terms shall be governed by applicable laws. Any disputes shall be resolved in the appropriate jurisdiction.
