Privacy Policy

Last Updated: January 1, 2026

At D4U Video Downloader ("we", "our", or "the Service"), we take your personal privacy seriously. This Privacy Policy outlines the types of information we collect, how it is handled, and our unwavering commitment to data minimization.

1. Zero Media Storage Guarantee

D4U Video Downloader functions strictly as a real-time web bridge. We do not host, store, copy, or retain any user-downloaded video, audio, or image files on our servers. When you request a download, the media stream is transferred in memory-efficient real-time chunks directly from the public content delivery network (CDN) to your browser. Once your transfer completes or terminates, no residual media remains on our infrastructure.

2. Information We Process

To maintain security, prevent automated abuse, and enforce hourly rate limits, we process the following technical telemetry:

  • Anonymized IP Hashes: We do not store raw user IP addresses in our download history. Instead, IP addresses are converted into cryptographic SHA-256 hashes combined with a secret server-side salt, rendering the data pseudonymized.
  • Submitted URLs: URLs submitted for analysis are processed temporarily to resolve public OpenGraph metadata and ensure rate compliance.
  • Standard Web Server Logs: Standard HTTP request logs (e.g. browser User-Agent, timestamp, request URI) may be maintained for a maximum of 30 days for server health diagnostics and DDoS mitigation.

3. Cookie Usage & Local Storage

We use minimal cookies strictly necessary for core functionality:

  • Session Cookies: A secure, HTTP-only session cookie is used to store CSRF protection tokens and prevent cross-site request forgery attacks.
  • Local Storage: Your browser's localStorage is used solely to store your light/dark display theme preference (d4u_theme).

4. Third-Party Advertising & Analytics

We may partner with third-party advertising networks (such as Google AdSense) to serve non-intrusive advertisements that help fund the maintenance of this free portal. These providers may use cookies (including Google DART cookies) to serve ads based on user visits to this and other websites. You may opt out of personalized advertising by visiting Google Ad Settings (google.com/settings/ads).

5. Security Protections

We implement industry-standard safeguards including end-to-end HTTPS encryption, DNS rebinding defenses, Server-Side Request Forgery (SSRF) filters, and PDO prepared database queries to ensure all operations remain secure.
