According to the Article 29 Working Party, a just-in-time notice is a type of privacy notice that provides processing information at specific points of data collection, such as when the user clicks on a certain feature or enters personal data1. This kind of notice is commonly recommended for AI-based technologies because it allows the user to receive relevant and timely information about the processing of their data, without being overwhelmed by lengthy and complex privacy statements1. A just-in-time notice can also be combined with other types of notices, such as layered notices or privacy dashboards, to provide a more comprehensive and user-friendly transparency framework1. Therefore, option C is the correct answer. Option A is incorrect because a privacy dashboard notice is a type of notice that provides the user with a centralised and interactive overview of the processing of their data, and allows them to manage their privacy settings and preferences1. Option B is incorrect because a visualization notice is a type of notice that uses graphical elements, such as icons, symbols, colours, or animations, to convey the processing information in a more intuitive and engaging way1. Option D is incorrect because a layered notice is a type of notice that provides the processing information in a hierarchical and modular way, starting with the most essential information and allowing the user to access more details if they wish1.
