When Mouseflow records a user, we gather the HTML snapshot that the user was presented with. It is important to note that the external files, such as stylesheets, media files, and scripts are retrieved from the domain's server, and fetched at the time of playback. We then use the HTML snapshots that we gather from recordings to display your heatmaps.
We only store recordings and analysis data for a limited period, which varies according to the different plans. You can read more about the data storage for each plan on our pricing page.
Note: If these files, suddenly become unavailable - this can throw off the playback and heatmap data. In the case that the files have been deleted - the request will return a 404 "not found" message.
