Even if the distribution ends, you will always be able to enjoy your valuable, paid-for content entirely offline as a lifelong collection.

  • CoApp is a dedicated lightweight PC support tool designed to pair with the browser extension. The extension itself handles "video discovery and button display," while CoApp takes care of "actual video data processing and safe file saving" in the background. Thanks to this smart separation, you get high-quality downloads without slowing down your browser at all.
  • Yes, it is completely safe. CoApp has been verified as safe by the leading security (anti-virus) software. All processing is performed locally on your PC; it never accesses your browsing history, personal files, or account information. All connections are strongly encrypted with SSL/TLS.
  • Ordinary browser extensions are restricted by strict security rules (sandboxing) and cannot directly write files to your PC’s folders or process advanced video data. CoApp safely overcomes these restrictions and plays an essential role in converting videos into beautiful MP4/MKV formats and securely saving them to your designated folder. This is the industry-standard design to provide a safe and highly functional tool.
