The paper focuses on a detailed micro-study describing changes in the behaviour of the authors of this article before and during the COVID-19 pandemic based on data from Google Location. Although the study evaluates data on only three individuals and may not be sufficiently representative to draw generalizing conclusions, it is a unique example of possible data processing that is not normally evaluated at such a level of accuracy. The article evaluates changes in the behaviour of authors before and after the introduction of anti-epidemic measures, but the main purpose is to point out the possibilities of analytical processing of such data while being aware of the issue of personal data protection. We recognize that by visualizing our real motion data, we partially disclose our privacy. Nevertheless, we find it very valuable to show how detailed data Google collects about much of the population and how such data can be used effectively.
