The following application statistics are based on the analysis of web server requests. All data comes from Tor web server logs which are provided in a stripped-down version of Apache's "combined" log format without IP addresses, log times, HTTP parameters, referers, and user agent strings.
This graph shows absolute numbers of requests to Tor's web servers made by Tor Browser to check whether a newer version is available or to download a newer version, broken down by release channel.
