It’s no secret to anyone that Google is trying through its proprietary services to track any activity of each person. Now it became known that the user’s purchases from the company are at a glance. The company has developed a special tool that analyzes all the checks received by the client’s mail. All purchase information is stored in a separate section of the Gmail mail service. Google noted that they do not monitor users, but only facilitate their work on the Web. Purchasing data that is stored in a separate section is not available to outsiders. Why do we need such a service? The company simply explains that in one place you have collected all the information on the purchased goods and services, and Google is convenient to analyze it in order to understand the preferences of users. Experts are skeptical of such explanations and believe that the company should have informed the users about this before. It is possible that the service helps in the selection of contextual advertising. In addition, it is not known how long Google collects data on user checks. Security experts recommend deleting purchase data.
