Kotlin DSL: Why am I able to get logs in release build from Play Store?

Question

We did not enable logging in release mode yet when we connect a USB cable and run Android Studio, we're able to get logs from release build downloaded from the store.

buildTypes {
        debug {
            isMinifyEnabled = true
            isShrinkResources = true
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )

            configure<CrashlyticsExtension> {
                // No need during development, enabling it also prevents Gradle to work offline
                mappingFileUploadEnabled = false
            }

            signingConfig = signingConfigs.getByName("debug")
        }
        release {
            isMinifyEnabled = true
            isShrinkResources = true
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )

            signingConfig = signingConfigs.getByName("release")
        }
    }

Do we need to explicitly disable logging in build variant when using Kotlin DSL?

For confidentiality this is a compact view of log, but these logs are pointing to app's package name. Running on Samsung A32 Android 13.

Might be mistaken, but you might need to add a proGuard rule to your proguard-rules.pro, something like:

-assumenosideeffects class android.util.Log {
    public static int d(...);
    public static int e(...);
    public static int i(...);
    public static int v(...);
    public static int w(...);
}
