Cookie Policy

Last Updated: January 30, 2026

This Cookie Policy explains how HiveMQ uses cookies, web beacons, pixels, tags, JavaScript, and similar tracking technologies (collectively, “Cookies”) on our websites and in our email communications.

This Cookie Policy should be read together with our Privacy Policy, which explains how we collect, use, share, and protect personal data more generally, and how you may exercise your privacy rights.

1. What Are Cookies and Similar Technologies?

Cookies are small text files that are placed on your device (computer, tablet, smartphone) when you visit a website. Cookies and similar technologies allow websites to recognize your device, remember preferences, and collect information about how users interact with online services.

• We also use technologies such as:

• web beacons or pixels (small graphic images embedded in webpages or emails),

• tags and JavaScript, and

• similar tracking technologies,

which may function alone or together with cookies.

2. How HiveMQ Uses Cookies

When you visit our websites, HiveMQ or authorized third parties may place Cookies on your device that collect information, including personal data, about your online activities over time and across different websites or online services.

We use Cookies to:

• operate, maintain, and secure our websites;

• enable core functionality and navigation;

• remember user preferences and settings;

• understand how visitors use our websites;

• improve website performance and user experience;

• measure the effectiveness of our communications and campaigns; and

• support marketing and brand awareness activities.

3. Session Cookies and Persistent Cookies

We use both:

• Session cookies, which exist only during a single browsing session and are deleted when you close your browser; and

• Persistent cookies, which remain on your device until they expire or are deleted.

4. Categories of Cookies We Use

The table below describes the categories of Cookies and similar technologies we use, their purposes, and how you can manage them.

HiveMQ does not sell personal information and does not share personal information for cross-context behavioral advertising within the meaning of the California Consumer Privacy Act (CCPA/CPRA).

5. Cookies and Tracking in Email Communications

We may use web beacons, pixels, or similar technologies in our email communications to understand engagement, such as:

• whether an email was opened; or

• whether a link in an email was clicked.

This information helps us measure the effectiveness of our communications and improve their relevance. You may unsubscribe from marketing emails at any time using the unsubscribe link included in the emails or by contacting us as described in our Privacy Policy.

6. Social Media Features and Embedded Content

Our websites may include social media features, such as sharing buttons, embedded videos, or interactive widgets (“Social Media Features”).

Social Media Features may be hosted by third-party platforms or directly on our websites. When you interact with these features, the relevant third party may collect information about your interaction in accordance with its own privacy policies. If you are logged into a social media account, the platform may associate your interaction with your profile.

For more information about how HiveMQ processes personal data in connection with social media, please see the Branded Social Media Pages section of our Privacy Policy.

7. Managing Your Cookie Preferences

7.1 Cookie Preferences Tool

You can manage your Cookie preferences at any time by clicking the “Cookie Preferences” link available in the footer of our websites (where available). This tool allows you to enable or disable certain categories of Cookies, except for Required Cookies. Changes may take effect on your next visit, depending on your browser settings.

7.2 Browser and Device Controls

Most web browsers allow you to control Cookies through browser settings, including blocking or deleting Cookies. You may also be able to configure your device settings to limit tracking.

Please note that blocking or deleting Cookies may limit the functionality of our websites and services.

7.3 Do Not Track Signals

Some browsers offer a “Do Not Track” (DNT) or similar signal. Because there is currently no consistent industry standard for responding to these signals, HiveMQ does not currently commit to responding to DNT signals. We will continue to monitor developments in this area.

8. Legal Bases for Cookie Use (Where Applicable)

Where required under applicable data protection or ePrivacy laws:

• Required Cookies are used based on our legitimate interest in operating secure and functional websites;

• Functional, Analytics, and Advertising Cookies are used based on your consent, which you may withdraw at any time via the Cookie Preferences tool.

9. Updates to This Cookie Policy

We may update this Cookie Policy from time to time. The “Last Updated” date reflects the current version.

Material changes will be communicated where required by law.
