Cookie policy

Emercom uses cookies and browser storage for analytics, advertising measurement, session replay and live chat. Essential cookies stay on either way. Our own cookieless page-view counter runs until you switch it off under Manage, and you can change your choice later under Cookie settings.

Cookie policy

Cookie settings

Choose what to allow. Essential cookies keep you signed in and protect forms; they are always on.

Analytics

Google Analytics measures how pages are used. Until you allow it, Google receives cookieless pings only.

Advertising

Google Ads measures whether an ad brought you here. Until you allow it, no advertising cookies are set.

Session replay

OpenReplay, run by Emercom, records what the page shows and how you use it: page content, clicks, scrolling and page changes. Text typed into forms is masked and passwords are never recorded. Emercom support can also watch a session live to help you; a call or screen control asks you first. If you are signed in to the dashboard, the recording carries your account email.

Live chat

Chatwoot, run by Emercom, powers the support chat and sets a cookie so a conversation continues across pages.

Umami

Umami, run by Emercom, counts page views without cookies. It is on by default. You can turn it off here.
