Cookie Policy

This Cookie Policy explains how CIEN (“we,” “us,” or “our”) uses cookies and similar technologies when you visit shopcien.com and related pages. It applies to customers shopping with us in the United States and elsewhere.

Last updated: August 31, 2026

What Are Cookies?

Cookies are small text files placed on your computer, tablet, or mobile device when you visit a website. They are widely used to make sites work efficiently, remember your preferences, keep you signed in, and help us understand how our store is used.

We also use similar technologies such as pixels, tags, and local storage (for example, to keep your shopping cart or wishlist). In this policy, we refer to all of these collectively as “cookies.”

Some cookies are set by CIEN directly (“first-party cookies”). Others are set by third parties who provide services on our behalf, such as Shopify (our ecommerce platform), payment processors, analytics providers, and advertising partners (“third-party cookies”).

Types of Cookies We Use

Essential Cookies

These cookies are necessary for the website to function and cannot be switched off in our systems. They are usually set only in response to actions you take, such as setting your privacy preferences, logging in, adding items to your cart, or completing checkout. Essential cookies enable core features including shopping cart, secure account access, checkout, and fraud prevention. Without them, the site may not work properly.

Functional Cookies

Functional cookies remember choices you make and provide enhanced, more personal features. They may remember your preferred language, region, previously viewed products, or wishlist items saved on your device. These cookies help us deliver a smoother browsing experience but are not strictly required for the site to operate.

Analytics & Performance Cookies

These cookies help us understand how visitors use CIEN so we can improve the site. They collect information such as pages visited, time spent on pages, traffic sources, device type, and approximate location. We use analytics tools (including Vercel Analytics) to measure site performance and identify issues. Data collected through these cookies is typically aggregated and used to improve navigation, product discovery, and overall experience.

Advertising & Marketing Cookies

Advertising cookies may be set by us or by our advertising partners to build a profile of your interests and show you relevant ads on CIEN and across other websites and platforms. This may include Meta (Facebook/Instagram) Pixel and similar technologies that measure campaign performance, track conversions (such as purchases), and help us retarget visitors who have shown interest in our products. These cookies do not store your name or payment details, but they may uniquely identify your browser and device.

How Long Cookies Last

Session cookies expire when you close your browser. They are typically used for temporary tasks such as keeping items in your cart during a visit.

Persistent cookies remain on your device for a set period (or until you delete them). They may remember preferences, support analytics, or enable advertising features across visits.

Third-Party Cookies & Partners

When you shop on CIEN, third-party services may set cookies in connection with:

Shopify — store operations, cart, checkout, and security
Payment providers — secure payment processing
Vercel Analytics — site performance and usage insights
Meta Pixel — advertising measurement, retargeting, and conversion tracking
Email & marketing tools — newsletter delivery and campaign analytics (when you subscribe)

These partners have their own privacy and cookie policies. We encourage you to review them. We do not sell your personal information; however, advertising and analytics partners may process data as described in this policy and our Privacy Policy.

Managing Your Cookie Preferences

You can control cookies through your browser settings. Most browsers allow you to refuse or delete cookies. Steps vary by browser (Chrome, Safari, Firefox, Edge, etc.). Visit your browser’s help pages for instructions.

Please note: if you block essential cookies, parts of the CIEN experience—such as cart, checkout, or account login—may not work correctly.

For advertising cookies, you may also use industry opt-out tools such as the Digital Advertising Alliance or Network Advertising Initiative. On mobile devices, you can limit ad tracking in your device settings.

Meta provides controls for ad preferences through your Facebook or Instagram account settings.

U.S. Privacy Rights (Including California)

If you are a resident of California or another U.S. state with applicable privacy laws, you may have rights regarding personal information collected through cookies and similar technologies. These may include the right to know what data is collected, to request deletion, and to opt out of certain sharing for cross-context behavioral advertising where required by law.

To exercise these rights, or for more detail on how we handle personal information, please see our Privacy Policy or contact us using the details below.

“Do Not Track” browser signals are not uniformly standardized. We currently do not respond to all DNT signals, but we honor applicable opt-out mechanisms described in this policy and our Privacy Policy.

Updates to This Policy

We may update this Cookie Policy from time to time to reflect changes in technology, law, or our practices. When we make material changes, we will update the “Last updated” date at the top of this page. We encourage you to review this policy periodically.
