Technologies for selectively excluding user data from machine learning operations include a compute device. The compute device includes circuitry configured to receive user data that defines content associated with a user and write the user data as one or more immutable entries in a data structure. The circuitry is also configured to receive a request to selectively exclude, from an analysis of the user data in the data structure, a portion of the user data that meets a set of criteria. Additionally, the circuitry is configured to analyze the user data in the data structure while excluding, from the analysis, user data that satisfies the set of criteria.
