Deciding what Chrome data you’re sending to Google.
Today we are going to explain how to change what Chrome data you’re sending to Google. Security experts are warning that from version 69 of Chrome, the browser automatically starts your Google session when you do it on any of its websites. This starts the content synchronization of the browser in the cloud, which allows you to synchronize your passwords and history with other devices on which you use Chrome.
However, this also means that Google is collecting this data about you, and synchronizing the browser to you, which will help it to have more data about what you do on the network, for example, to sell advertising. To avoid this, we will start by explaining to you how to prevent Chrome from automatically logging you into your Google account by doing it on any of their websites, and then we’ll tell you how to decide what data you synchronize in your cloud.

Prevent Chrome from signing in automatically
The first thing you have to do is prevent Chrome from logging in with your Google account automatically when you start it in a web service such as Gmail. To do this open write chrome: // flags / # account-consistency in the address bar. On the screen you go to click on the Default indicator in Identity consistency between browser and cookie jar (1), and in the drop-down menu you must choose the Disabled option (2) to disable automatic syncing.
Once you have done it, a message will now appear at the bottom of your browser to restart the browser. Click on this Relaunch Now button that will have appeared below everything in blue, and your browser will automatically restart to apply the change you have entered.

How to configure what you sync with Chrome
But in the event that you want to log into Chrome, the browser still has a tool with which you can decide which elements to synchronize in the Google cloud so that they are available in the Chrome versions of your other devices, and therefore to You decide what data to give Google about you.
To configure these parameters, click on the three dots icon (1) that you have at the top right of the browser. Once you open the pop-up menu with it, click on the Settings option (2) to enter the section where you can synchronize different Chrome parameters.

Now that you are in the settings, simply you must click on the Synchronization option that will appear just below your profile name, and before the passwords. It will take you to the menu where you can control which items you sync with Google by sending them to their servers.
In the Advanced Synchronization Settings screen, you will see that by default you have the Synchronize all option activated. Therefore, if there is data that you do not want to send to Google disable the Sync All option toggle, and by doing so you will see that now you can deactivate the options you want.

Now you only have to deactivate the synchronization of the data that you do not want to send to Google. In any case, keep in mind that all the data that you do not synchronize will not be sent to the rest of the devices on which you are using Chrome. You may therefore want to share some things with Google after all.
If in addition to stopping syncing data, there are also some that you want to delete from Google’s serversIn this section you will also see the option * Manage synchronized data in the Google Control Panel, which will give you the possibility to reset the data that you have already sent to synchronize.
