Cookie Policy
Effective Date: October 27, 2025
Introduction: This Cookie Policy explains how Harmonic (“we” or “us”) uses cookies and similar tracking technologies on our website. It should be read together with our Privacy Policy (above) for a full picture of how we collect and use your information. By using the Harmonic website, you can control your cookie preferences as described in this policy. We aim to be transparent about our use of cookies and ensure you have the tools to manage them in compliance with GDPR and other privacy regulations.
1. What Are Cookies?
Cookies are small text files that are placed on your computer or device when you visit a website
cytrio.com
. They are widely used to make websites work efficiently and to provide information to the site owners. Cookies allow our site to remember your actions and preferences (such as login, language, and other display preferences) over a period of time, so you don’t have to re-enter them whenever you come back to the site or browse from one page to another. They also help us understand how our site is being used and enable certain features and content.
In addition to cookies, we may use other tracking technologies like web beacons (tiny graphic images embedded on pages or emails) or pixels and local storage. For simplicity, this Cookie Policy refers to all of these as “cookies.” These technologies serve similar purposes as cookies, such as counting users who have visited a page or opened an email, or storing small bits of data locally in your browser to remember your preferences.
2. Cookies We Use and Their Purposes
We categorize the cookies we use on the Harmonic website by their purpose. Below are the main types of cookies that may be set when you visit our site:
Strictly Necessary Cookies: These cookies are essential for the operation of our website and platform. They enable core functionality such as user authentication, account login sessions, and security. Without these cookies, services you have asked for (like accessing secure account areas or making payments) cannot be provided. For example, when you log into your Harmonic account, we set a session cookie to keep you logged in as you navigate the site. These cookies do not gather information about you for marketing or remember where you have been on the internet. Because they are necessary for the website to function, they are placed based on our legitimate interest and do not require user consent under applicable law
cytrio.com
. However, you can still block them via browser settings (see Section 5), though doing so may break certain features of the site.
Functional (Preferences) Cookies: These cookies allow our website to remember choices you make and provide enhanced, more personal features. They may be set by us or third-party providers whose services we have added to our pages. For instance, if our site offers a live chat support or remembers your language or region preference, functional cookies are used to recall those settings so you have a tailored experience. These cookies are not strictly necessary, but they enhance your user experience by personalizing content and interactions. We may ask for your consent to use certain functional cookies, especially if they are provided by third parties. If you do not allow these cookies, some or all of these services may not function properly.
Analytics and Performance Cookies: We use analytics cookies to collect information about how visitors use our website – for example, which pages are visited most often, how users move around the site, and if they encounter errors. This data helps us improve the way our website works, understand user interests, and measure the effectiveness of our content. For example, we might use Google Analytics, which sets cookies like _ga to collect anonymized statistics about user visits (Google’s ability to use and share information collected by Google Analytics about your visits to our site is restricted by the Google Analytics Terms of Use and Privacy Policy). We might also use HubSpot cookies to analyze user engagement with our marketing materials. We treat these cookies as non-essential, which means we will ask for your consent before placing them
cytrio.com
. Data collected by these cookies is typically aggregated and not intended to identify you personally. However, if you have an account with us, we might tie some analytics data to your account information for internal analysis – but only as permitted and with respect for your privacy. If you opt out of analytics cookies, your visits will not be tracked in our analytics tools.
Advertising and Marketing Cookies: Harmonic is not an advertising platform, but we may use a limited number of marketing cookies to promote our services and measure campaign effectiveness. Marketing cookies record your visits to our site, the pages you have viewed, and the links you have followed. They may also track your browsing across other sites to understand your interests and show you relevant ads. For example, we could use the Facebook Pixel or Google Ads cookies so that, after visiting our site, you may see advertisements for Harmonic on Facebook or Google’s networks (a practice known as retargeting). These cookies also help us cap how often you see an ad and measure whether an ad was useful (e.g., did you sign up after seeing it?). We only deploy advertising cookies with your consent. If you do not accept these cookies, you will experience less targeted advertising from us. (You may still see our ads on other platforms, but they will not be specifically tailored based on your web behavior on our site.)
Third-Party Cookies and Tools: Some cookies on our site are placed by third parties on our behalf. For example, as mentioned, Google Analytics (analytics cookie) and HubSpot (analytics/marketing cookies) are third-party services that set cookies when you visit our site
cytrio.com
. Similarly, if we embed a YouTube video or a social media sharing plugin, those services may set their own cookies. We also integrate with services like QuickBooks or CMMS systems, but those typically operate through secure API connections rather than cookies. However, if any third-party content or widget on our site uses cookies, we will disclose it and, where necessary, obtain consent. We do not control third-party cookies; the respective providers are responsible for them. We recommend you read the privacy and cookie policies of those third parties for information on their cookies and data practices.
Cookie Duration: Some cookies are “session cookies” which are temporary and deleted from your device when you close your browser. Others are “persistent cookies” which remain on your device for a set period or until you delete them. For instance, a session cookie might keep you logged in during your visit, whereas a persistent cookie (e.g., for preferences or analytics) might remember you when you return to the site days later. The duration of each cookie is different – some may expire after a few days, others might last for several months or even years (for example, a persistent analytics cookie might remain for 6-24 months unless cleared). We provide details of cookie lifespans in our cookie consent tool on the website.
3. Legal Basis for Cookies (Consent and Legitimate Interests)
Under GDPR and ePrivacy laws, we classify strictly necessary cookies as those that do not require prior consent because they are needed for the service you expressly request (e.g., to log in, add items to a cart, etc.)
cytrio.com
. We rely on our legitimate interest in ensuring our site functions properly as the legal basis for using these necessary cookies.
For all other types of cookies (functional, analytics, advertising), our legal basis is your consent. This means we will not set or use these cookies unless you have given us permission via the cookie banner or settings. On your first visit, no non-essential cookies will fire until you choose your preference (e.g., clicking “Accept All” or selecting certain categories in a cookie settings panel). You can change your mind at any time (see Section 4 below on managing preferences). We keep a record of your consent choices as required by law. If you are an EU/EEA user, by consenting in our banner you explicitly agree to the placement and use of cookies as described herein.
We also want to highlight that you have the right to withdraw consent for non-essential cookies at any time
cytrio.com
. Withdrawing consent will not affect the lawfulness of data collected while the consent was active, but it will stop further data collection by those cookies.
4. Your Cookie Choices and How to Manage Cookies
Cookie Consent Tool: We provide a cookie consent banner and preference center on our site (visible on first visit, and always accessible via a “Cookie Settings” link in the website footer or in this policy). This tool allows you to accept or reject different categories of cookies (except strictly necessary ones, which are always enabled). You can opt in or out of functional, analytics, and marketing cookies as you prefer. If you want to change your selection later, simply revisit the Cookie Settings link to adjust your preferences. We will honor your most recent preferences. For example, if you initially accepted all cookies but later opt-out of analytics cookies, our site will stop using those analytics cookies on your browser and remove any that can be removed.
Browser Settings: In addition to our site’s controls, you can manage cookie storage through your web browser settings
cytrio.com
. Most browsers (Chrome, Firefox, Safari, Edge, etc.) allow you to:
View and delete cookies on a per-site basis;
Block third-party cookies (cookies set by domains other than the one you’re visiting);
Block all cookies from being set; or
Receive notifications when a cookie is about to be set, allowing you to accept or decline it.
Please refer to your browser’s help documentation for instructions on how to use these features. Here are quick links for major browsers: [Include links or mention names e.g. “Google how to clear cookies on [Browser]”]. Keep in mind that if you disable cookies in your browser, it may affect the functionality of not only our site but others as well. Essential functions (like staying logged in) often rely on cookies, so blocking them might impair your experience.
Do Not Track (DNT): Some browsers have a “Do Not Track” feature that sends a signal to websites indicating you do not want to be tracked. Our site responds to cookie consent rather than DNT signals, because there is not yet a standard for how DNT requests should be interpreted. We recommend using the cookie controls described above for the most effective way to manage your tracking preferences on our site.
Opt-Out of Google Analytics: If you wish to opt-out of Google Analytics across all websites (not just ours), Google provides an opt-out browser add-on which you can install. Similarly, for interest-based advertising, you can visit sites like the Network Advertising Initiative’s opt-out page or Your Online Choices (EU) to opt out of many ad networks.
5. Updates to this Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in the cookies we use or for other operational, legal, or regulatory reasons. As with our Privacy Policy, we will post any changes on our website with an updated effective date. If the changes are significant, we may provide a more prominent notice or seek your consent if required (for example, if we add new cookie categories that require consent). We encourage you to review this Cookie Policy periodically to stay informed about our use of cookies and related technologies. Cookies and third-party scripts can change over time, so we review and update our policy regularly – at least every 6–12 months or whenever we introduce new cookies
