Your wearable's numbers are estimates. Here's how we treat them.

Last week a class action was filed against Oura, alleging its rings can't measure what's needed for sleep staging while marketing near-clinical accuracy. We're not going to pile on. Plenty of people love their rings, and wearables are genuinely useful for spotting your own trends. But it's a good moment to say plainly how Nila handles the numbers that come in from your phone, watch or ring, because we made different choices on purpose.

We never score you. No sleep score, no readiness score, no recovery grade, no letter or number that pretends a wrist sensor watched you sleep the way a lab would. When your device says seven hours and twelve minutes, we show you seven hours and twelve minutes, exactly as it arrived.

We never stage your sleep. REM, deep, light: those are estimates a device makes from movement and heart rate. They can be some way off what a sleep study would find. We label them as estimates every place they appear, and we don't build features on top of them that imply more precision than exists.

We never diagnose. A dip in heart rate variability or a run of short nights is not a diagnosis of anything. It is a pattern in your own record, worth noticing, worth logging against how you actually felt, and worth mentioning to a doctor or specialist if it keeps showing up. That is where it stops.

We keep counts, not causes. When Nila's pattern view puts your imported numbers beside your own check-ins, it shows what happened on the same days. It does not claim one caused the other. Sleep was short AND hot flashes were heavy is a true sentence. The sleep CAUSED the hot flashes is not one we will write for you.

Your felt experience wins. Every surface in Nila that shows device numbers carries the same note: if a number doesn't match how the night actually felt, trust how it felt. You are the instrument that matters. The watch is a second opinion from a gadget that was guessing.

Why be this strict? Because midlife is exactly when the stakes get real. If you're deciding whether to raise a symptom with your doctor, or whether a treatment is helping, you deserve data presented with honest edges: here is what the device estimated, here is what you logged, here is the conversation to have next. Inflated confidence would be easier to market. It would also be wrong.

If you use Apple Health or Health Connect, your numbers sync into /track under these rules, and the full version of this stance lives on our disclaimer page. Questions about how we handle your data are always welcome: ask Nila, or write to us from the footer.
