HTTP Cookie
A small text file stored in your browser. It's not a program and cannot read files on your computer. Think of it as a short-term memory for our site.
Cookie Policy
We believe transparency builds trust. This policy outlines exactly how Ultra4K Downloader uses cookies to enhance your experience while respecting your privacy.
Executive Summary
Ultra4K Downloader employs a limited set of technical cookies solely to ensure our download tool functions reliably and to remember your preferences, such as your chosen video format.
We do not use cookies for tracking across other websites, personal profiling, or intrusive advertising. Our approach is utility-first: if a cookie doesn't help you download faster or manage settings, it isn't used.
You maintain full control. Our global cookie consent banner, managed by our dedicated plugin, lets you adjust preferences at any time without affecting core functionality.
Terminology
Plain-language definitions for the technical terms we use.
Session Cookie
A temporary cookie that expires when you close your browser. We use it to keep your download queue active during a single visit.
Persistent Cookie
Remains on your device for a set period. We use this sparingly for things like remembering your preferred video quality setting.
First-Party Cookie
Set directly by our domain (ultra4kdownloader.world). We only use these for essential site functions and security.
Third-Party Cookie
Set by a domain other than ours. We use these minimally for functionality (e.g., embedded content), not for tracking.
Consent
Your explicit permission to store cookies. Our system treats your choice as a binding instruction—no cookies work without your okay, except for strictly necessary ones.
What Cookies We Use
Our cookie usage is categorized by purpose. Each serves a specific, technical function tied directly to delivering the download tool.
Strictly Necessary
Essential for security, network management, and accessibility. Example: CSRF tokens to prevent unauthorized form submissions. These are always active.
Preferences
Remembers your settings. Example: Your preferred video download format (MP4, WebM) and quality (1080p, 4K). Expires after 30 days.
Analytics
Anonymous, aggregated data. Example: Counting how many users complete a download from YouTube vs. Vimeo. No personal data is collected.
Example: Cookie storage in a browser's developer tools panel.
Why & How We Use Cookies
Cookies are not an arbitrary choice; they are the simplest, most secure mechanism for state management in a browser-based tool. Here’s the engineering rationale.
1. Session Integrity for Complex Downloads
Video processing is stateful. When you initiate a 4K download, the server needs to track your session's progress, queue position, and file chunks. A session cookie provides this lightweight state without requiring you to create an account. It’s deleted when you close the tab.
2. Functional Configuration Without Complexity
A persistent cookie for 'video format preference' means your interface renders buttons and options for MP4 by default. This prevents repetitive user selections across sessions, reducing friction. It’s a performance optimization for you, not surveillance for us.
3. Security and Anti-CSRF
Strictly necessary cookies (like CSRF tokens) are embedded in the page. They verify that a download request genuinely came from the Ultra4K Downloader interface and not a malicious script. This is a standard security practice for any web application handling file operations.
4. What We Explicitly Avoid
We do not use cookies for: Retargeting ads across the web, selling data to data brokers, creating user profiles for sale, or tracking you on other sites after you leave. Our cookie use is confined to the technical operations of ultra4kdownloader.world.
Third-Party Cookies
We use essential third-party services. Any cookies they set are governed by our strict limitations.
Payment Processor
For subscription management (e.g., Stripe). Cookies may be set to process your payment securely. We do not store your financial data; the processor handles it. Their cookie policy is independent but their use is necessary for the pricing page.
Video Platform Embeds
Some tutorial pages may embed videos from YouTube or Vimeo. These platforms set their own cookies. We do not control these cookies and you are subject to their policies when viewing embedded content.
Anonymous Analytics
We use a privacy-focused analytics tool (e.g., Fathom, Plausible). It collects aggregated data about browser types, page views, and download initiations. It cannot identify you as an individual and does not share data for advertising.
No Social Trackers
We do not use Facebook Pixel, Google Ads, or any social media tracking pixels on our site. No cookies are set for social media retargeting or conversion tracking.
Methodology: How We Evaluate Cookie Use
Every cookie used on Ultra4K Downloader is vetted against a simple, three-question framework during development:
- Necessity: Does this cookie directly enable a core feature of the downloader (security, state, preference)? If not, it is excluded.
- Duration: Is the persistence justified? Session cookies expire at browser close. Persistent cookies have a maximum 90-day lifespan, with most under 30 days.
- Transparency: Can a user easily understand its purpose? If the name "Google Analytics" is clear, so is our explanation. We avoid obscurely named cookies.
This framework ensures our cookie architecture remains lean, secure, and aligned with the tool's utility-first design philosophy.
Your Control & Choices
