Google Knows Everything About You: Here Is How to View and Block It
In the current digital era, Google’s services have become inseparable from daily life. From searching for information via Google Search and sending messages through Gmail to navigating routes on Google Maps and watching entertainment on YouTube, almost all of a user’s online activities are centred around this tech giant’s ecosystem.
Behind the convenience offered lies a significant fact: Google collects and stores detailed traces of user activity through its various services. This data is collected with specific purposes. For Google’s parent company, Alphabet Inc., this information serves as a valuable asset used to improve service performance, provide personalised recommendations based on user habits, and serve as the primary basis for presenting relevant advertisements. While this data collection practice has become a global tech industry standard, it also raises significant questions regarding privacy and the limits of user surveillance.
According to records from CNBC Indonesia, Google builds a profile for every user, ranging from basic identity to personal habits, including:
Full name, gender, and date of birth
Mobile numbers and personal email addresses
Entire search history
List of visited websites and content read
Personal preferences, including types of sports, food, hobbies, and lifestyle
Demographic information such as residence and workplace location
Movement history and visited locations
YouTube watch and search history
Users have the right to know what information has been collected and to manage how that data is used. Google provides transparency access, although these settings are often hidden and rarely noticed. Here is a complete guide to tracing the personal data stored on Google’s servers:
- Viewing Ad Preferences and Profiles
One of the easiest ways to see how Google profiles you is by examining the types of ads displayed. This data is compiled based on recorded online habits.
Ensure you are logged into your personal Google account.
Visit the ‘Manage Ads Settings’ link. This page will display the profile Google has built about you, including estimated age, gender, and a list of topics and interests deemed relevant to you.
Here, you can see which advertising categories you prefer and a list of advertisers you have blocked. This page also explains why you see certain ads, allowing you to understand how your behavioural patterns are translated into marketing data.
- Tracing Location History his feature may be one of the most surprising for many users. Since 2010, Google has stored the location history of users who have enabled location services on their devices. This data is integrated with Google Maps and search services.
To view your travel records, access the Google Locations History Page.
There, you can view a timeline map containing records of places you have visited, the duration of visits, travel routes, and even the modes of transport used.
While Google uses this data to improve traffic prediction accuracy and provide local recommendations, it also means your physical movements are recorded in detail over time.
- Accessing YouTube Activity History
YouTube is more than just a video platform; it is a massive source of data regarding user interests, opinions, and information needs. Every keyword typed into the search bar and every video played is stored to build a personalised recommendation list.
You can review this trail through the YouTube Search History and YouTube Watch History menus.
From this data, Google learns whether you prefer educational, entertainment, or news content, which is then used to customise ads on the platform and other Google services.
How to Stop Google’s Surveillance
Increasing awareness of digital privacy has led many users to want to reduce their data footprint. Fortunately, Google provides options to control or even stop these monitoring practices. However, there are consequences to understand. If data collection is disabled, Google will no longer have the material to customise its services. Consequently, ads will become random and less relevant, search suggestions will no longer be personalised, and the convenience of features like route predictions or content recommendations will decrease significantly.
Here are the steps to disable activity tracking, quoted from a CNET guide:
Open Google.com via a browser on a computer or mobile device.
Log in to the Google account you wish to manage.
Click the profile icon in the top right corner, then select ‘Manage your Google Account’.
In the left-hand menu, select the ‘Privacy & Personalization’ tab, then click ‘Manage your Data & Personalization’. This section is the main control centre for all your privacy settings.
Scroll down to the ‘Activity Controls’ section, then select ‘Manage your Activity Controls’. This contains the primary settings for what Google is permitted to store.
You will see a box labelled ‘Web & App Activity’. Switch the toggle to the ‘off’ position to disable it. This stops the storage of search activity, visited sites, and app usage.
Google will display a notification that…
