Terms / 使用说明
These independent utilities are provided without a usage fee. You retain your input and output. Please keep originals and verify results before using them in important work. / 工具免费使用，请保留原文件并核对输出。
Scope / 功能范围
There is no hosted AI generation, transcription, human review, or recovery of information already lost from a file. File and browser limits are explained in each tool. / 不提供在线 AI 生成、转录或已丢失数据的恢复。
Advertising / 广告
Paid placements are labeled Sponsored / 广告. A sponsorship does not imply endorsement. Advertisers must have the rights to their creative and destination. A submitted inquiry is not acceptance of a contract. We do not promise minimum traffic or sales. / 合作需另行确认，不承诺流量或销售额。
Availability / 可用性
We may fix, change or retire a tool. The site is not intended for emergency or safety-critical decisions. Report a problem or request data deletion through the contact form linked below. / 可通过合作表单反馈问题或请求删除联系信息。
Optional, one-time support / 一次性自愿支持
The tools remain free. Support is voluntary and one-time, with no subscription, advertising placement, membership or priority service. Suggested support is USD 3; enter USD 1, 3, 5 or another amount directly on PayPal. Buttons do not preset the amount. This is ordinary tool support, not a charitable or tax-deductible donation. Payments are checked manually; a checkout visit or return is not a receipt. For a payment issue or refund request, use the contact form linked above. / 工具继续免费使用。支持为一次性自愿付款，不是订阅，不包含广告位、会员或优先服务。建议 $3，也可在 PayPal 输入 $1、$5 或其他金额；按钮不会预填金额。这不是慈善或可抵税捐赠。到账需人工核对；付款问题或退款请求可通过上方联系入口提出。
PayPal checkout may still display the old Advertising Services label. The support entry is voluntary support for the free tool and does not purchase advertising. Enter SUPPORT in the required Campaign reference field; neither the amount nor this reference is prefilled. / PayPal 结账可能仍显示旧的 Advertising Services 名称；支持入口是对免费工具的自愿支持，不购买广告位。必填的 Campaign reference 请填写 SUPPORT；金额和备注均不会预填。
