Your recordings stay on your phone unless you choose to send them
What you can choose to send from Nightsong™, and what keeping audio on the phone costs you: no audio backup, re-scoring limits, and battery.
Published Updated
Nightsong listens to you sleep. That is a real act of trust, so we built it around one line:
Your recordings stay on your phone unless you choose to send them.
The listening, the math, and the morning number all happen on the phone in your hand.
That is the promise. This page is about the price, because every design choice has one, and you deserve to know it before you trust us with your nights.
Where the work happens
Every recording, all of the audio analysis, and your nightly Somnus Index™ are made on your phone. When you open your night and tap Snore to listen to your loudest moments, you are playing clips stored on the device. How a phone can do all that work locally is explained in how a phone can measure a night by itself, and the step-by-step scoring is in how the Somnus Index works.
What you can choose to send
Sharing is opt-in. If you tap Share and help improve Nightsong, then after the phone makes your Index, a few numbers from that night, such as minutes of snoring, breathing steadiness, and your score, go to our own secure storage. No name, no email, and no account handle goes with them, and no audio. Tap Not now and no numbers are sent. You can change your mind any time under You, then About, then Sharing choice.
If you join the waitlist, we keep your email so we can reach you. It is never joined to your sleep data.
The Village™: sharing with people you choose
The Village is how you share your nights with people you invite. It shares only five things: your name, hours, score, snore number, and breathing rhythm. Only the people you invite see them. Recordings are never part of it.
The cost, part one: no backup of your audio
Nightsong does not back up your audio. If your phone is lost, stolen, or erased, the audio on it goes with it, and we cannot restore it.
Snore clips also do not pile up forever. Your loudest moments auto-clear after 7 nights. If there is a night you want to remember, listen to it that week.
The cost, part two: limits on re-scoring old nights
Cloud services can keep your raw data and re-run it every time their software improves. We do not keep your audio, so we cannot do that. When the engine on your phone gets better in an update, it works on the nights it hears from then on. There is no saved copy of last spring to send back through it. Your history is the history your phone scored at the time.
We think that is the right trade. It does mean your trend is a record of what was measured when it happened, not a document we can rewrite later.
The cost, part three: your phone does the work
A server farm does not do the heavy lifting here. Your phone does. Listening and analyzing for a whole night is real work, so keep the listening phone plugged in, and skip video or heavy apps on it overnight. If you see no number in the morning, a dead battery is one of the most common reasons.
Storage is the phone’s too. The optional Enhanced explanations download, which brings richer plain-word reads of your nights, is about 400 MB, Wi-Fi only, and it is stored on the phone.
Why we pay these costs
A recording of you sleeping is about as personal as data gets. So you decide what is sent, and the numbers you choose to share carry no name. The night is used to score the night. No ads. We do not sell your nights. Your audio never reaches us, so nothing is trained on it. We would rather pay these costs than ask you for more trust than we need.
If privacy is why you are here, you may also like how to track snoring and breathing privately on your iPhone. The short factual version lives on Nightsong at a glance. The beta is full right now, so join the list and we will reach out when a spot opens.
