On the occasion of a comment on Facebook that I called the Opera browser "spyware", I went through the process of downloading again the most beautiful and easiest to use browser and find the best privacy settings.
To begin with, let me state that the fact that using Windows 10, let alone the MS Edge chromium I use, also means accepting my monitoring.
The difference lies in the fact that Microsoft is not wholly owned by a Chinese company responsible for personal data breaches and under the supervision of the Chinese regime, which has no respect for the privacy of its citizens out of political conviction.
In privacy policies states
By default, Microsoft Edge developed on non-Windows platforms does not send diagnostic data or location information to Microsoft. When Microsoft Edge is deployed in Windows 10, the default is to send user-based diagnostic data.
In addition to the options given to us for the volume and type of data we send to Microsoft, you can at the link
https://privacy.microsoft.com/el-gr/
read the privacy policy and compare it below with what Opera is asking us to accept.
My operating system is Windows 10 2004, I use Proxy and as an antivirus I have trial version Kaspersky 20.0.141085 and MS Defender Firewall.
I downloaded the 64bit version of Opera Version: 69.0.3686.36 and also the 64bit version of Opera GX LVL2 (core: 68.0.3618.191)
I did the same setup and check on both versions, the screenshots are from the GX version.
Below I quote the License and the Terms of Privacy translated into our native language by Google Translate to understand what you do Accept with the installation of Opera:

When we collect personal data, we generally act as a "data controller" as defined by applicable law. The exact categories of data we collect, why we collect them, and the opt-out options depend on the application or service you use, as described in more detail below.

When the installation is complete, press Alt + P and the settings are displayed. Below I list all the settings so that not all Opera services are used (so I do not give my permission to collect information) and the strictest privacy options for chromium browser.
Twitch wants flash so we turn it off
In Website Settings → Cookies and website data
In advanced settings
In the address bar / bar we write
Opera: // flags /
and make the following settings:
Press Relaunch and when Opera opens we click on the GX corner
and in the Comments we press the gear and turn everything off. "Free games" are not selected.

In Autofill Test Opera fails
Installing Adguard extension addresses "vulnerability"
In the next steps of the test the results were the same as MS Edge and Chrome so I skip them. The choice Send do not track requests is disabled in Opera.
It may be at the disposal of any website to accept or reject compliance with this request, but on the recommendation of the European Union all
Browsers must give their users a choice
https://www.w3.org/blog/2018/06/do-not-track-and-the-gdpr/
So the "Finnish" company writes on the soles of its shoes something that within the GDPR is a particularly important choice to state your disagreement.
In conclusion, it is the right of each user to choose the software that meets his needs with the criteria he chooses, my choice is the following
which is completed by deleting the Opera Software folder in path C: \ Users \ ”username” \ AppData \ Roaming
For those who continue to use Opera, I recommend following the guide and adopting the above settings.

@ did you read them and are they bullshit?
