Velmun comes from three places: physics, data protection and software engineering.
taught us where computation belongs. The phone in your pocket has more processing power than the server room that first sold you the cloud. Sending your data across the world to be computed and sent back is not a technical necessity — it is a business model. We skip it.
taught us what the law actually asks of anyone who holds personal data — and that the cleanest way to meet it is not to hold the data at all.
taught us how to build that: apps that are complete on their own, encryption that happens before anything leaves the device, sync that works without knowing who you are.
We like apps that are private, secure and technically clean. Not as a feature — as a starting condition. We take methods from fields that have solved hard prediction problems — weather forecasting, signal processing — and put them to work in everyday apps. Quietly, on your device.
naido predicts when your baby will be tired. Before we shipped it, we tested what everyone expects us to use: machine learning, gradient boosting, a sleep-science model with tuned parameters. On nine months of real sleep data, every one of them lost to a simple, robust estimate built from your baby's own recent rhythm.
The reason is honest physics: a baby changes faster than a model can learn it. What was true at two months is wrong at eight. A method that trusts the last few days beats one that has memorised the last few months.
We also measured the ceiling. Even with perfect knowledge of the day's average, no method gets much past half of naps within twenty minutes. The rest is noise — a baby is not a clock. So we stopped pretending.
Instead of a single time that looks precise and isn't, naido shows a window sized to your child's variability. In four out of five cases, the nap starts inside it. That number is measured, not promised — and it's why we show a window where others show a minute.
The strongest signal isn't in any model. It's you. When you notice the first yawn and tap "getting tired", that one tap beats every calculation — because it's new information, not old information recomputed. We built the app around that button.
There are two kinds of subscription. One pays for a running service — a relay, electricity, someone maintaining it. The other holds your own data behind a gate and charges rent for the key. Our sync is the first kind. Cancel, and the app keeps running with everything in it. You lose a service, not your records.
We don't claim our apps do more than the big ones. They do less. In return they run on your phone, and what they transmit is sealed before we see it.
Because we can.
