⚠ We do not collect personal information of your website visitors (names, addresses, phone numbers, etc.). Bot log values are limited to the first 100 characters and auto-deleted after 30 days. Source IP addresses identified as bots are retained for 90 days as a spam IP list, in order to protect other registered domains from the same bot, and are then deleted automatically.
