Privacy Policy

Last updated: September 7, 2026. This Privacy Policy details how BilibiliDownloader.co ("we", "our") manages technical data and protects user privacy when you visit our website or use our media extraction tools.

We do not require user account registration, passwords, credit card information, or phone numbers. The service is strictly intended for visitors aged 13 and older.

When you submit a public Bilibili URL, our backend only parses the stream playlist metadata required to present available download formats to your browser. We never store, log, or redistribute the videos or audio files you download.

Watermark removal and audio format extraction run client-side on your device using WebAssembly technology, ensuring your media never leaves your local browser memory.

Our web servers automatically record minimal standard technical logs (such as truncated IP address, browser user-agent, and error codes) purely for security, load balancing, and preventing automated abuse.

To provide free access to all visitors, our site displays ads served by Google AdSense and its advertising partners. These third-party vendors use cookies and web beacons to serve ads based on your visit to this site and other websites on the Internet.

You can learn more about how Google handles advertising data by reviewing the links below or managing your advertising settings at any time.

We use browser local storage exclusively to save your interface preferences, such as light/dark mode and language selection. We do not use first-party tracking cookies.

You may configure your browser settings to reject cookies or delete stored data at any time. For comprehensive details on advertising cookies and regional consent requirements, refer to our Cookie Policy.

Depending on your jurisdiction (such as GDPR in the EU or CCPA/CPRA in California), you may have specific statutory privacy rights. Because we do not require accounts or store personal files, we maintain minimal personal data. If you have any inquiries regarding data protection or wish to submit a privacy request, please contact hello@bilibilidownloader.co.
