There should be a switch for “DL” users to disable the native notification alerts and sounds. For instance, when this switch is enabled, the sounds when sending or receiving messages should be the default sounds for your phone, not the Grindr sounds. This can allow very discreet users to have their notifications turned on without worrying about being exposed.

Or there can be radio options in the settings to choose what sounds or ringtone we want for Grindr:

___ Grindr Sounds
x Phone’s Default Sounds
___ Vibrate Only
___ Sound Off
