Ich stütze mich bei meinem Kommentar auf die beste Quelle: Datenschutzerklärung-Opera
Hier heißt es:
When you install an Opera application, a random installation ID is generated. We may collect this identifier, as well as your device ID and hardware specification, operating system and environment configuration, and feature usage data.
Sie nutzen diese Daten aber nur um ihre Dienste zu verbessern
In short, this information helps us to improve our products and services
Weitere Daten werden über dein News-feed und Verhalten gesammelt:
To provide you with more relevant news content in certain countries and languages, we collect some information about the articles you read in the application’s native news feed, and your general location. This information is linked to a randomly generated News ID and may be stored on our servers up to three months.
Außerdem werden durch Dritte "Personalized ads" geschaltet:
Based on advertising IDs and your general location, some of our mobile applications may serve targeted ads. These ads are provided by our monetization partners. You can always adjust your personalized ad choices in the application’s “Settings” menu or through your operating system’s settings.
Ob diese die Daten behalten bleibt hier offen, aber ich vermute es doch stark
Weitere Daten werden durch "Crash Reports" gesammelt
Weitere Daten werden bei bestimmten Features gesammelt, dass kann man aber bestimmt auch selber durchlesen, da habe ich jetzt keine Lust drauf :D
Opera nutzt "third-party-cookies"
We use cookies on our websites for session management and retaining your settings or preferences. We may also use third-party cookies to collect visitor statistics and measure our marketing campaigns. If you would like to reject third-party cookies, please configure your browser’s settings accordingly.
Jetzt weitere Infos zu Third Party:
Our applications and services include third-party technology or code, some of which may use your data in different ways. When such third-party technologies use previously collected data, they typically act as data processors for us. When they collect data on their own, they typically act as independent data controllers. For convenience, we have included links to their privacy policies below. Data controllers are marked with an asterisk.
Opera for computers and all our mobile applications use:
Google Geolocation API *.
Es werden darunter auch noch andere Dienste aufgelistet, wie Opera Touch, Opera für Android, etc.
Dass was vielleicht noch interessant ist, ist Opera News:

AppsFlyer ,
Facebook SDK *,
Firebase Cloud Messaging ,
Google AdMob *,
Outbrain *.
Hoffe, dass hat geholfen. Bei den vielen "komischen" antworten hier. Die Datenschutzerklärung selber zu lesen, wäre natürlich auch eine gute Möglichkeit gewesen ;)
LG
