Factor Tools 会记录匿名的使用情况，以了解网站是否正常工作以及哪些功能需要改进。
记录内容包括：每日活跃浏览器、界面语言、设备宽度范围、网站版本，以及打开材料选择、执行计算、切换结果视图等功能事件和汇总数量。
统计数据不包含工厂方案内容、目标产量、保存的方案、搜索文字、IP 地址或完整浏览器标识。浏览器标识随机生成并每天更换，不能用来跨天追踪用户。统计数据最多保留三个月。
网址加入 ?analytics_test=1 后会进入统计测试模式；这类记录和自动化测试记录不会计入正式统计。
Factor Tools records anonymous usage events to check that the site works and learn which features need improvement.
The dataset includes daily active browsers, interface language, viewport range, release version, feature events such as opening the item picker or running a calculation, and aggregate counts.
It does not contain factory plan contents, target rates, saved plans, search text, IP addresses, or full user-agent strings. A random browser identifier changes every day and cannot follow a user across days. Usage data is retained for up to three months.
Adding ?analytics_test=1 to the URL enables analytics test mode. Those records and automated test records are excluded from production statistics.
