The following third-party services may set their own cookies or use browser storage when you use SmartMQ:
Because SmartMQ only uses cookies that are strictly necessary to provide the service, most browser cookie controls will not affect your ability to use the core app. However:
You can clear cookies and browser storage at any time in your browser settings — this will sign you out.
You can use your browser's private/incognito mode, though you will need to sign in each session.
Blocking all cookies may prevent you from signing in to SmartMQ.
For users in the European Economic Area (EEA), our use of strictly necessary cookies is based on Legitimate Interest (Article 6(1)(f) GDPR) — these cookies are required for the service to function and cannot be disabled without breaking core functionality.
We do not use cookies that require your consent under the EU ePrivacy Directive, as we do not use analytics, advertising, or non-essential tracking cookies.
We may update this Cookie Policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. We will notify users of material changes via email or in-app notification.
