TrueLearn does not collect or share any personally identifiable information. Due to its privacy centric nature no data must be retained as learning event data does not need to be stored after training.

Definitions

A Learning Event consists of a topic name and timestamp when that topic was last watched by the user.

Information Collected

Learning Events

When a learner watches a transcribed video, the transcript is pre-processed to determine the topics in that video. The topics in the video and the timestamp of when that video was watched forms a learning event. These learning events are then passed to the Classifiers to conduct training to refine their assumptions about the learner’s knowledge, with no additional information required. The default behaviour is to not retain this information however it is up to the discretion of the developer whether learning events are stored or not.

Usage of Information

The developer may choose to store the history of learning events to construct visualisations that demonstrate how the learner’s knowledge has progressed overtime. However, importantly no other information other than Learning Events are needed to provide this functionality.

Information Shared

No information is shared between parties, TrueLearn does not collect any data itself. Affiliated collection of data is done only by users of the library to store Learning Events.

Retention of Information

Retention policies of learning events are at the discretion of the developer using the library to implement, please see their privacy policy for more information.
