Check-in services (CISs) are a highly relevant part of location-based services that provide customer value greater than other mobile services due to their technical possibilities; conversely, CISs also create various risks to privacy, as they enable the continuous live tracking of users. We investigate these risks and develop a third-order privacy risk construct based on communication privacy management (CPM) theory to explain how a set of concerns violates privacy boundary mechanisms and generates perceived privacy risk. A developmental mixed-method design is used to qualitatively derive the construct qualitatively through 20 interviews and evaluate it quantitatively using a privacy calculus model with structural equation modelling (N = 431). The results confirm the third-order privacy risk construct and reveal new underlying concerns that create this risk. The results of this study are useful for both practitioners and academics, as they provide insights into how context-specific privacy concerns emerge in advanced mobile services, such as CISs.

签到服务（CIS）是基于位置的服务中高度相关的一部分，由于其技术可能性，其提供的客户价值高于其他移动服务；相反，由于CIS可实现对用户的持续实时跟踪，因此它们也给隐私带来各种风险。我们调查了这些风险，并基于通信隐私管理（CPM）理论开发了三阶隐私风险结构，以解释一系列关注点如何违反隐私边界机制并产生感知的隐私风险。一种发展性的混合方法设计用于通过20次访谈定性地定性生成构造，并使用带有结构方程模型的隐私演算模型（N = 431）对其进行定量评估。结果证实了三阶隐私风险结构并揭示了造成此风险的新的潜在问题。这项研究的结果对从业者和学者都非常有用，因为他们可以洞悉高级移动服务（例如CIS）中如何针对特定上下文的隐私问题。
