1. Introduction to Cookies & Tracking

At Yu Sleep USA (operating as "Yu Sleep Labs", "Yu Sleep", "we", "us", or "our"), we are committed to being completely upfront and transparent about how we interact with your browser, handle your digital telemetry, and collect information across our official website located at https://en-yusleep.org/ (the "Site").

This Cookie Policy operates in tandem with our published Privacy Policy and Terms and Conditions. It explains clearly what tracking technologies we deploy, why we rely on them to power our digital storefront, and how you can exercise full control over your preferences at any time.

Consumer Summary: We use cookies to maintain your shopping cart, ensure checkout payment security, understand site performance, and present relevant educational sleep health material. You can configure or decline non-essential cookies at your discretion.

2. What Exactly Are Cookies?

A cookie is a compact text file containing a string of alphanumeric characters that is transferred to and stored upon your personal computer, smartphone, tablet, or other internet-connected device whenever you visit a website. Cookies allow that site to recognize your specific hardware, recall previous preferences across browsing sessions, authenticate account sessions, and tailor user interfaces.

Cookies can be categorized by longevity and origin:

  • Session Cookies: These temporary files exist only for the duration of your active browsing session. The moment you close your web browser software, these cookies are automatically deleted from your device's memory.
  • Persistent Cookies: These tokens remain stored on your hard drive or mobile storage after your browser is shut down until their pre-configured expiration date passes or you manually delete them through browser cache tools.
  • First-Party Cookies: Cookies set directly by Yu Sleep's host domain (en-yusleep.org) to govern fundamental site operations, such as shopping basket retention.
  • Third-Party Cookies: Cookies placed on your device by approved external partners, such as web traffic analytics engines, payment gateways, or digital marketing platforms.

3. Categories of Cookies We Deploy

To provide an intuitive, high-speed shopping environment for our dietary supplement, Yu Sleep employs four core classes of digital tracking technologies:

A. Strictly Necessary (Essential) Cookies

These cookies are indispensable to the core functionality of our Site. Without them, you would not be able to navigate between pages, add Yu Sleep bottles (1-Month, 3-Month, or 6-Month packages) to your virtual order, or transition securely to our encrypted checkout gateway. Because they are vital for providing requested online services, applicable privacy regulations (including the EU ePrivacy Directive) do not mandate prior opt-in consent for strictly necessary cookies.

B. Performance and Analytical Cookies

Analytical cookies aggregate anonymous diagnostic information regarding how visitors interact with our content. They count visits, identify bounce rates, log server latency, and pinpoint which educational guides or ingredient reviews receive the highest engagement. All analytical telemetry is processed in an aggregated, pseudonymous format and does not identify you as a unique individual.

C. Functionality and Preference Cookies

These cookies enable our platform to recall customized choices you have made during prior visits, such as your preferred shipping destination state, closed promotional banners, and applied promotional discount vouchers (such as the DEEPSLEEP10 coupon). They ensure you do not have to repeatedly re-enter basic configurations.

D. Targeting and Advertising Pixels

With your consent, third-party marketing networks may set pixels or cookies to measure advertising conversion rates, calculate marketing return on investment, and deliver relevant advertisements regarding natural sleep supplements across partner display networks. These cookies prevent repetitive ads and ensure promotional discounts reach consumers genuinely seeking circadian rest solutions.

4. Summary of Specific Cookies Used

5. Web Beacons, Pixels & Local Storage

In addition to conventional text cookies, we may occasionally employ supplementary digital tracking methodologies to facilitate our operations:

  • Web Beacons / Clear GIFs: Tiny, invisible graphic images embedded within our digital storefront or HTML customer order confirmation emails. These beacons inform our engineering team whether a transactional email was successfully received, opened, or clicked.
  • HTML5 Local Storage: Client-side browser storage mechanisms utilized to cache client preferences, shopping cart states, and script assets locally on your device, drastically reducing web page loading speeds upon subsequent visits.
  • Server Log Files: Standard automated server log records capturing IP addresses, browser user-agents, timestamps, and referring URLs strictly for technical server debugging, bot detection, and anti-fraud monitoring.

6. Third-Party Integrations & Analytics

We collaborate with reputable technology partners who may deploy cookies through our platform to deliver their respective features:

  • Google Analytics: We utilize Google Analytics (GA4) with IP anonymization activated to analyze user engagement patterns. Google processes data on our behalf in compliance with contractual data protection agreements. You can opt out of Google Analytics across all websites by installing the official Google Analytics Opt-Out Browser Add-On.
  • PCI-DSS Certified Payment Gateways: When completing a purchase, our payment processing bridges may set session tokens necessary to authenticate cardholder identity, satisfy 3D-Secure verifications, and prevent credit card fraud.
  • Content Delivery Networks (CDNs): Cloud-based acceleration networks utilize load-balancing cookies to route your traffic to the nearest regional data center, ensuring fast loading of ingredient graphics and scientific text.
Third-Party Privacy Regimes: Third-party services operate under their own independent privacy and cookie disclosures. We encourage you to review their respective corporate privacy frameworks for detailed tracking governance.

7. How to Manage & Disable Cookies

You retain complete, unrestricted authority over whether your browser stores cookies. Most desktop and mobile web browsers automatically accept cookies by default, but you can readily adjust your application settings to block cookies, notify you whenever a cookie is set, or wipe your stored cache completely.

Instructions for common web browsers can be found at their official support portals:

  • Google Chrome: Navigate to Settings > Privacy and Security > Third-party cookies.
  • Apple Safari (macOS/iOS): Open Preferences / Settings > Privacy > Block all cookies or Prevent cross-site tracking.
  • Mozilla Firefox: Go to Settings > Privacy & Security > Enhanced Tracking Protection.
  • Microsoft Edge: Select Settings > Cookies and site permissions > Manage and delete cookies and site data.

Impact of Disabling Cookies: Please understand that if you choose to reject or block strictly necessary cookies, key components of the Site—including our dynamic checkout cart, order fulfillment funnel, and currency formatters—may fail to function correctly.

Industry Opt-Out Platforms: For interest-based advertising preferences, you may also utilize industry-wide self-regulatory opt-out registries:

  • United States: Digital Advertising Alliance (DAA) at aboutads.info or Network Advertising Initiative (NAI) at networkadvertising.org.
  • European Union: European Interactive Digital Advertising Alliance (EDAA) at youronlinechoices.eu.
  • Canada: Digital Advertising Alliance of Canada (DAAC) at youradchoices.ca.

8. Global Privacy Controls & Do Not Track

We acknowledge and respect emerging privacy-enhancing browser standards. Where recognized under applicable legal jurisdictions, our servers honor the Global Privacy Control (GPC) signal sent by compliant browsers. When our systems detect an active GPC beacon from an eligible user, we automatically treat that signal as a valid request to opt out of third-party marketing cookies and non-essential cross-context behavioral tracking.

Traditional "Do Not Track" (DNT): Historically, some web browsers introduced a "Do Not Track" header. Because the technology sector never established a universally accepted consensus standard for interpreting traditional DNT headers, our systems do not alter default responses when encountering older DNT flags unless accompanied by a recognized GPC signal or jurisdiction-specific mandate.

9. Compliance with GDPR, ePrivacy & CCPA/CPRA

Yu Sleep maintains rigorous compliance alignment with international and domestic data sovereignty regulations:

  • European Economic Area & UK (GDPR & ePrivacy Directive): For users residing within the EU, EEA, or United Kingdom, non-essential cookies (analytical and promotional) are set only after you have granted explicit, freely given, informed opt-in consent through our cookie consent interface. You may withdraw or modify this consent at any time.
  • California Residents (CCPA / CPRA): We do not sell your personal identifiers or biometric data for monetary payment. To the extent that third-party advertising cookies constitute "sharing" under California law, California consumers hold the absolute right to opt out of such sharing via GPC signals or by contacting our privacy compliance desk.

10. Policy Updates & Contact Information

We may periodically update this Cookie Policy to account for changes in web tracking technologies, new legal precedents, or updates to our sleep supplement checkout architecture. When adjustments occur, we will update the "Effective Date" at the summit of this document. Continued navigation of our digital channels subsequent to revisions indicates your acceptance of our updated practices.
