Privacy Policy

The short version

• The public tool has no user account or sign-up flow.
• Do not paste passwords, account cookies, session tokens or private share secrets.
• The application code does not create a user download-history database.
• The supplied build contains no advertising or cross-site tracking script.

When you submit a link

The URL is sent to this server, which asks Bilibili or Bstation for public page and media information. The response is used to display available video, audio, caption and cover choices. The application processes the link for that request and does not intentionally save a permanent copy of the submitted URL.

When you download a file

Download buttons use short-lived signed tokens. The server validates the token and relays an allowed source file or, when required and supported, temporarily processes media with FFmpeg. The application does not intentionally keep the completed media as a library after transfer.

Routine logs

Hosting and security infrastructure may record an IP address, timestamp, requested path, status code and user agent. Application errors may also be recorded for diagnosis. Retention and access depend on the actual hosting configuration, which the code package alone cannot verify.

Third parties

Bilibili or Bstation receives requests from the service when a link is checked or a source file is relayed. Your browser, network provider and hosting provider also process normal connection data. Their policies are separate from this one.

Your choices

Use only public media URLs and close the page without submitting if you do not want the URL processed. For questions, use contact. For acceptable use boundaries, see copyright and acceptable use.
