Currently, only the latest version of Syntiox DL receives security updates. We strongly recommend always pulling the latest changes from the main branch and keeping your dependencies up to date.

If you discover a security vulnerability within Syntiox DL, please DO NOT open a public issue.

Instead, please report it directly to the maintainer by contacting:

• Email: sh4lu.z@gmail.com

All security vulnerabilities will be promptly addressed, and a patch will be deployed as soon as possible.

Because this application interacts with your local system and third-party platforms (YouTube, Instagram, Facebook), please strictly adhere to the following safety practices:

If you use the 'cookiesfrombrowser' feature to download age-restricted or private videos (e.g., from Instagram or Private Facebook Groups), the script temporarily accesses your active browser session.

• Never share your generated executable (.exe) or logs with others if it contains your personal cookie data.
• Do not run this script on public or shared computers while logged into your personal social media accounts.

Syntiox DL requires ffmpeg to merge video and audio streams.

• ONLY download ffmpeg.exe from official, trusted sources (such as the BtbN GitHub Releases linked in the README).
• Never place unverified .exe files in the project folder, as they can execute malicious code on your machine.

The core extraction engine, yt-dlp, is frequently updated to bypass restrictions and patch vulnerabilities. Always ensure you are running the latest version by executing:

pip install --upgrade yt-dlp
