Google privacy settings
Google knows a lot about you and it is also necessary to take some measures to lock down your Google data leakage.
Block email tracking
Every person online will definitely have an email account. There is a way for the senders to know whether you have opened the emails or not, when and how many times you opened the email.
This technique used by both marketing companies and individuals, is called pixel tracking. However, this can be blocked in Gmail.
When you log into your Gmail account, click the gear icon in the upper righthand corner, then select “Settings.” Scroll down to see the “Images” row, and select “Ask before displaying external images” and save. This would break pixel tracking.
Stop location tracking
Google tracks your location wherever you go with your device, using the feature “Location History” even when you are not using a specific Google service.
In order to stop this when you log into your Google account click the circular icon in the upper righthand of the screen. Next, click Google Account” > “Privacy & personalization” > “Location History” > and then toggle the slider to “Paused.”
Delete your purchase history
Google tracks your purchases as well if you are using Gmail. The list of all your purchases is compiled from “[orders] placed using Google services, like Google Play Store, Google Express, or through the Google Assistant” in addition to “Purchase & reservation receipts or confirmations received in Gmail.”
This cant be turned off, by the items can be deleted from the list. In order to do so, go to https://myaccount.google.com/purchases and look under “Gmail confirmations.” Next, click the item you want to remove and select “Remove Purchase” -> “View Email” -> “More” (the three vertical dots on the right side of the screen) -> “Delete this message.”
This has to be done for each item separately.
Stop using Google search
Stop using Google for search and instead, use DuckDuckGo, which is a search engine that doesn’t track you. If you really need to do Google search then do so after logging out of your Google Account. Also try to use different browser, like Firefox, for all your non-Google Account needs.
