Cookie Policy

Effective Date: October 2025

This Cookie Policy explains how ZILK Sleep (“ZILK,” “we,” “us,” or “our”) uses cookies and similar tracking technologies when you visit our websites — including zilksleep.com, zilksleep.nl, zilksleep.de, and related domains (collectively, the “Sites”).

We use cookies to improve your browsing experience, analyze site performance, personalize content and ads, and understand how visitors interact with our brand.

1. What Are Cookies?

Cookies are small text files placed on your computer or device when you visit a website. They allow the site to remember your actions and preferences over time — such as login details, items in your shopping cart, or language settings.

Cookies can be “first-party” (set by ZILK) or “third-party” (set by our partners, like analytics or advertising providers).

2. Types of Cookies We Use

3. Cookies We May Use

Our Sites may use the following cookie and tracking technologies:

• Shopify cookies (cart, checkout, session)

• Google Analytics cookies (traffic and conversion measurement)

• Meta Pixel / Facebook Ads cookies (retargeting and ad performance)

• Klaviyo cookies (email and on-site tracking)

• TikTok or Pinterest tracking cookies (if ad campaigns are active)

We review these regularly to ensure compliance with applicable privacy laws.

4. How We Use This Information

We use cookie data to:

• Operate and secure our website

• Process orders and remember shopping cart contents

• Measure website performance and improve usability

• Provide relevant marketing messages and promotions

• Prevent fraud and maintain website security
  
  

We never sell cookie data, and all third-party partners must comply with strict data protection agreements.

5. Managing and Disabling Cookies

When you first visit our Sites, you’ll see a cookie consent banner that lets you choose which cookies to allow.

You can change or withdraw your consent at any time by clicking “Cookie Preferences” in the footer of our website.

You can also manage cookies directly in your browser settings:

6. Legal Basis for Processing (GDPR)

For visitors in the European Economic Area (EEA) and United Kingdom, we only use non-essential cookies with your consent. Our legal bases for processing cookie data include:

• Contract performance (for essential cookies used to complete a purchase)

• Consent (for analytics and marketing cookies)

• Legitimate interests (for site security and fraud prevention)

You can withdraw consent for non-essential cookies at any time via our cookie banner or browser settings.

7. Data Retention

Cookies are stored for different durations depending on their purpose:

• Session cookies expire when you close your browser.

• Persistent cookies remain until manually deleted or automatically expire (typically between 30 days and 2 years).

We retain cookie-related data only as long as necessary to fulfill the purpose for which it was collected.

8. Updates to This Policy

We may update this Cookie Policy from time to time to reflect changes in technology, law, or our business practices. Any updates will be posted on this page with a revised Effective Date.
