5. Third-Party Cookies

Some cookies on our website are set by third-party services. We do not control these cookies and their use is governed by the respective third-party privacy policies:

• Google / Firebase: Google Privacy Policy
• Google Analytics: Google Analytics Cookie Policy

6. Managing Your Cookie Preferences

You can control and manage cookies in several ways:

• Browser Settings: Most browsers allow you to refuse, delete, or manage cookies through their settings. Refer to your browser's help documentation for instructions.
• Opt-out Tools: For Google Analytics, you can install the Google Analytics Opt-out Browser Add-on.
• Cookie Banners: When applicable, our cookie consent banner allows you to accept or decline non-essential cookies.

Please note that disabling certain cookies may affect the functionality of the Zyntex website or app. Essential cookies cannot be disabled as they are necessary for the service to function.

7. Do Not Track

Some browsers include a "Do Not Track" (DNT) feature that signals websites not to track your activity. As there is no universally accepted standard for DNT responses, our website does not currently respond to DNT signals. However, you can use the cookie management options above to limit tracking.
