Hi @InconspicuousProton,

The app’s language is linked to the the language of your device, if you want to change it you have to go through your devices’ settings :). If you were to use the web version, you can use this article to change the language : https://support.deezer.com/hc/en-gb/articles/115003885105-Language-settings

Btw, you’re on the french Community here, you might find more answers on the english one here :)
