These logs are used solely for security purposes (intrusion detection via fail2ban) and are rotated periodically. They are never used for analytics, profiling, or marketing.
No Data Sharing
We do not sell, trade, or share any information with third parties because we don't collect any in the first place. All calculations happen locally in your browser using JavaScript.
