The mechanics are known. The American giant Google compulsively collects our data to monetize it, exploit it, recycle it. Chrome is one harvesting tool among others.
Take control of Settings
Fortunately, this is not a fatality. If the browser is automatically configured to spy on us quietly, it is possible to curb its curiosity, limit its prerogatives but also strengthen its security.
Discover below 6 tweaks to make Google Chrome safer and more respectful of your data and privacy.
Important : each setting is accessible from Chrome’s Settings, by clicking on the three vertical dots at the top right of the browser window.
1. Enable Enhanced Protection
After installation, Google Chrome defaults to “Standard protection against known dangerous downloads, extensions and websites”.
It’s good to know. There is a higher level called “Enhanced Protection” to activate manually:
Settings -> Privacy & Security -> Security -> Enhanced Protection
2. Prohibit Site-to-Site Tracking
A website you leave usually likes to track you and take note of the pages you visit in the process. Google is complicit in the practice but it is possible to ask the browser to limit it as much as possible:
Settings -> Privacy and Security -> Cookies and other site data -> Send “Do Not Track” request while browsing
Namely: the sites are not obliged to respect this request.
3. Block third-party cookies
In the family of cookies, these small files that archive and transmit information about our surfing sessions, the third-party cookie is a special specimen. This is a cookie placed by a site other than the one you are visiting. Might as well block them:
Settings -> Privacy and Security -> Sites Settings -> Cookies and Site Data -> Block Third-Party Cookies
“Third-party cookies are not necessarily necessary to take advantage of the resources available on the Internet: to limit your traces, it is recommended to refuse them by default”, advises the CNIL (National Commission for Computing and Freedoms) in France.
Please note that disabling third-party cookies may cause problems for some sites.
4. Prohibit saving passwords, addresses, payment methods
As you fill out forms and enter passwords online, Chrome offers to save them. Purpose of the maneuver: automatically fill in this sensitive data for you during future visits.
This concerns, for example, the shipping address of a package, your credit card number, the password to access a messaging service, etc.
To keep Google and Chrome away from this sensitive and potentially hackable data, here are the settings to change:
Settings -> Autofill -> Passwords -> Offer to save passwords
Settings -> Autofill -> Payment methods -> Save and enter payment methods
Settings -> Autofill -> Addresses and others -> Save and fill in addresses
5. Deny location access
Websites “may ask for your location” geographically, recalls Google, “to offer relevant features or information, such as local weather or nearby stores. »
If you want to hide this information forever and not have to systematically answer no when Chrome asks for your permission, here is the setting to change:
Settings -> Privacy and Security -> Sites Settings -> Location -> Do not allow sites to access your location
6. Forbid Preloading Prediction Pages
Google Chrome is a modern-day oracle. On the basis of cookies in particular, the browser tries to guess the web pages that you may visit soon and preloads them preventively.
It is a waste of resources and a dubious exploitation of your data that it is possible to neutralize:
Settings -> Privacy and Security -> Cookies and other site data -> Preload pages to speed up browsing and searching.
