I use SharedPreferences:

class MySharedPreference(context: Context) {
    private val appSharedPrefs = context.getSharedPreferences("have", Context.MODE_PRIVATE)

    fun setPreferences(key: String?, value: String?) {
        val prefsEditor = appSharedPrefs?.edit()
        prefsEditor?.putString(key, value)
        prefsEditor?.apply()
    }

    fun getPreferences(key: String?): String? {
        val json = appSharedPrefs?.getString(key, "")
        return if (TextUtils.isEmpty(json)) {
            null
        } else json
    }
}	

And ThemeHelper Object for lightmode and darkmode:

object ThemeHelper {
    const val lightMode = "light"
    const val darkMode = "dark"
    const val batterySaverMode = "battery"
    const val default = "default"

    fun applyTheme(theme: String) {
        when (theme) {
            lightMode -> AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO)
            darkMode -> AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES)
            batterySaverMode -> AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_AUTO_BATTERY)
            default -> AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM)
        }
    }
}

In Main Activity we use these classes:

mySharedPreference = MySharedPreference(this)

if (mySharedPreference.getPreferences("isDark") == "1") {
    ThemeHelper.applyTheme(ThemeHelper.darkMode)
    binding.switch1.isChecked = true
} else {
    ThemeHelper.applyTheme(ThemeHelper.lightMode)
    binding.switch1.isChecked = false
}

So, when user select DarkMode SharedPreferences value is "1" else common LightMode
