About

One mark. What you choose to prove.

SigWave is made by Synaping Inc. in Pasadena, California. Synaping was founded by Robb Dixon. Synaping also makes Synap, Synaping's personal knowledge system; the two are separate products, and Synap talks to SigWave only through the same public interface any other company would use.

A mark shown on a phone screen: a small wavy line with its sixteen-character code, ready for someone to scan

Why

Most IDs you carry today only work if you hand them over. A driver's license, a card number, a birth date. To prove you are old enough, you hand over a card that also shows your name, your address and your birthday. The other side keeps a copy. It sits in their files long after the moment has passed. Every copy is one more place it can leak from.

SigWave gives you a mark: a small wavy line that stands for you, the way a signature does. You make it on your own phone, or in your web browser. Anyone can see the mark. Its secret is made on your device and never leaves it. When someone needs to know one thing about you, say whether you are old enough, they ask your phone. Your phone answers only that, and only when you say yes. They get the answer and a receipt of it. You keep everything else. Today that answer rests on your own word; answers backed by your passport or by an issuing body are in development.

Two things are at the center today: your phone can answer questions about you, and, in our test builds, you can sign a paper so that anyone can point a phone camera at it on sigwave.id/scan and see whether you signed it and whether any line has changed since. The rest of this site labels each use plainly: Live if it works in SigWave today, Built in Synap if it works today in Synap, and In development if we are building it now. We are already building most of them, and we have confirmed that every one is technically feasible under our patent-pending design.

What we believe

Your mark is yoursMade on your phone. Only the devices you added can answer for it. A copy stays silent.
Answers, not copiesOnly the answer leaves your phone, and only when you send it. What it is based on stays with you. A name or a date goes only if you choose to send it.
No copies to leakThe side that asked keeps a yes and a receipt, not a copy of your license.
You keep the receiptsEvery question asked of you, and every answer you gave.
Investors

Made for other companies to build in.

SigWave is not something you buy at a store. It is made to be a part that a company builds into the way it checks people, the way a lock is built into a door. Today that starts at sigwave.id/ask. A verification library (Rust today) checks a mark, its device list and a signed record without calling sigwave.id. It is in use inside Synap and not yet offered outside. A written guide for building the ask into your own system is on the way. It is not a phone program that collects facts about people and sells them. There is nothing to sell. There is no column in it for a birth date, an address or an ID document, and a name or other detail is kept only when a person chooses to send it.

A mark has to work the same way in ten years as it does today. The company behind it has to still be there, answering to the people who carry one.

What to call it, and what is real.

The paragraph you may copy

SigWave is one mark, made on a person's phone. It answers questions about them and sends only what they choose. In its test builds it also signs papers, and anyone can check a signed page by pointing a phone camera at it on sigwave.id. It is made by Synaping Inc., a Pasadena, California company founded by Robb Dixon.

The name

In writing, the product is SigWave, with a capital S and a capital W. The logo spells it in small letters only: sigwave. The mark itself is a small wavy line with a sixteen-character code under it. It is not a barcode, and it is not one of those square codes you scan at a restaurant.

What is real and what is a sample

The app is real. The phone screens shown on this site are taken from it. The watch screens are from the Apple Watch app, which is in testing; nothing is proven on a wrist yet. The people, papers, cards, labels and objects shown on this site, and the town of Alder Falls, are samples made for the site. The one exception is the letter Robb Dixon signed on September 25, 2026. It is real: a printed page anyone can check by pointing a phone camera at it on sigwave.id/scan. The iPhone app is in testing. It is not yet out for everyone. The Mac app is public at dl.sigwave.id.
