### How is the userbase estimated?
We simply count the number of unique IPv4 addresses that connect to the Qubes update servers each month (except for Tor connections; see below).
We simply count the number of unique IPv4 addresses that connect to the Qubes update servers each month (except for Tor connections; see [below][tor-methodology]).
### How has the methodology for counting Tor users changed?

- `plain_users` is the number of unique clearnet IPv4 addresses that connect to the Qubes update servers each month.
- `plain_requests` is the total number of requests the Qubes update servers receive from clearnet IPv4 addresses each month.
We cross-reference the list of connecting IP addresses with the official database of Tor exit nodes in order to distinguish Tor and clearnet IPs and requests.
For this purpose, an IP address counts as belonging to a Tor exit node if there was a Tor exit node active for that address in the past 24 hours.
We cross-reference the list of connecting IP addresses with [TorDNSEL's exit lists] in order to distinguish Tor and clearnet IPs and requests.
For this purpose, we count an IP address as belonging to a Tor exit node if there was a Tor exit node active for that address within the 24-hour periods before or after it connected to the Qubes update servers.
### What kinds of data do you collect about Qubes users?
The only data we collect are:
We collect:
- The IPv4 addresses that connect to the Qubes update servers
- The number of requests from each IPv4 address
- Standard server access and error logs
We do not collect any other kinds of data about Qubes users.
### Where can I find the raw data and source code?
