Keep your conversations private.
Privacy Sound plays masking sound from a Bluetooth speaker or your iPhone so people nearby can't make out what is being said. The microphone only measures room volume — your words are never recorded.

Everything you need for speech privacy
Masking sound that covers speech
Cafe chatter, office ambience, waiting room, lobby and restaurant sounds blend into the background and make nearby conversation hard to make out.
Automatic volume adjustment
The mic measures the room's volume level and gently raises the masking sound when people start talking, then lowers it again when it's quiet. Changes are always smooth, never abrupt.
Nothing is ever recorded
The microphone reads volume only. Your conversations are never analysed, saved, or sent to any server. Privacy protection that never listens in itself.
White, pink & brown noise
Classic broadband noise generated in real time, plus an air-conditioning hum — steady, natural sound that's easy on the ears over long sessions.
Layer in natural sounds
Blend waves, stream, wind or forest over the masking sound and dial the mix ratio to taste — calmer for a consultation room, richer for an open office.
Ready-made presets
One tap sets the right sound and masking strength for clinic reception, pharmacy, consultation desk, negotiation space or meeting room.
Business-hours timer
Start and stop automatically during opening hours — masking begins when you open and stops when you close, with nothing to remember.
Favourites & Bluetooth
Save your sound, volume, masking strength and mix as a favourite, and play through any Bluetooth speaker or the iPhone's own speaker.
