This site uses a combination of nginx's server logs and Piwik (in log analytics mode) to gather and store traffic statistics.
No information is shared with third parties; this site does not use any third-party tracking resource whatsoever, with some temporary exceptions during Internet Defense League campaigns.
nginx logs
Data retention
nginx logs are rotated daily, and fall out of rotation after 7 days. Logs that fall out of rotation are deleted. They are not backed up.
Data recorded
The logs contain the following information for every request sent to this domain:
- Full request URL and method
- Full IP address of the client
- Which website you were visiting before you clicked a link to this website (HTTP Referer header)
- Which browser and operating system you use (HTTP User-Agent header)
- Whether or not you have chosen to not be tracked (HTTP Do Not Track header)
- Second-granularity request time
- Response status code and size of the response body
The exact line used for nginx's log_format
line can be found in the nginx configuration file for this website.
Piwik
Data retention
Piwik traffic statistics are stored indefinitely.
All requests that have the HTTP Do Not Track header enabled are not recorded.
Data recorded
Piwik traffic statistics contain the following information:
- Full request URL and method
- First two bytes of IPv4 addresses. IPv6 addresses are not truncated. If you would like to see this change, there is a bug about this on the Piwik bug tracker.
- Which website you were visiting before you clicked a link to this website (HTTP Referer header)
- Which browser and operating system you use (HTTP User-Agent header)
- Second-granularity request time
- Response status code
Opting out
If you would like your requests to be omitted from the Piwik traffic stats, simply enable Do Not Track. Requests that have the HTTP Do Not Track header will not be recorded.
nginx logs have no opt-out option, but only last for 7 days. If you would like to spoof some of the information they contain, here are some options you can use:
- Tor to anonymize your IP address
- RefControl to modify the HTTP Referer header on a per-website basis
- UAControl to modify the HTTP User-Agent header on a per-website basis
