Except for web server log files, this site does not store any information about visitors. Keeping server logs is a standard procedure for hosting providers, done in order to allow for an investigation after a security breach. For each visit, IP address, date / time stamp, URL visited, HTTP protocol, HTTP status, bytes transmitted, referrer URL, and OS / browser are stored. After being kept for a maximum of seven days, all logs are getting deleted by default.


I would love to hear back from you if you have any suggestions, questions, or other feedback.
