FAQs
Can unidentified users be tracked across multiple top-level domains (e.g. www.example.com and www.example.co.uk?
No. We use first-party cookies, which are only readable within a single domain, and therefore we cannot create identities that are shared across domains. We do not track users across domains.
Why don’t you have the secure flag set on your cookies?
We cannot assume that customers use HTTPS and as such, we cannot enforce this on our cookies.
If your site only uses HTTPS you can get in touch with our support team and request us to enable the secure flag for your Messenger cookies.
Why don’t you set the HTTPOnly flag for your cookies?
Our cookies need to be accessed by the Intercom Javascript and therefore we cannot enable this flag.
