How does this affect Insights data collection? On a particular day, this has very little impact, as we can expect 1 device to have only 1 device ID. Mobile apps and console platforms have different storage regimes, and device IDs are much more durable in those environments. This applies primarily to the web platform. But over a month, most browsers provide at least 2 device IDs for the same device, one ID initially and another after clearing and refreshing the cookie. So, on any given day, we can assume that a browser always provides the same device ID for a given device. The half-life of a cookie seems to be about 14 days, even if you ask the browser to store the cookie forever. Web browsers store device IDs using cookies.

For example, if someone loads an extension or watches a game on 2 devices, that involves 2 device IDs and counts as 2 Unique Viewers.

At a given moment, a device ID is assigned to a single hardware device. Counting Device IDsĪs explained below, some unique data fields (for example, Unique Viewers) are collected based on device IDs. New data fields may be added in new versions of the report, anywhere in the sequence of fields (that is, not necessarily at the end of the CSV). Once a data field is added to a report, it will not be deleted in future versions of the report. As a developer, you can use this data to enhance the experience of broadcasters and viewers and optimize how they engage with your games and extensions on Twitch Twitch Insights provides game and extension developers with analytics data to help developers make data-driven decisions about future development.
