There is no account here. Nothing of yours we could read, sell or hand over.
Messages go straight from phone to phone whenever both are awake. When yours is not, a sealed envelope waits on one of our nodes - we see that something arrived for an address, never a word of what it says. We never ask for your number, never touch your address book, and never learn your name.
The message is encrypted in the phone's own memory with Phone B's public key. What leaves for the relay is an unreadable stream of bytes. Your history stays on this device - unless you switch backups on, and then a copy sealed with your twelve words rests on a mailbox node too.
Runs without a Google account. It keeps the connection alive in the background, so a message or a call still reaches you while the phone sleeps.
Messaging, calls, video and groups all work. We run it on a real iPhone talking to a real Android phone on our desk - hardware, not a simulator. It is not in the App Store yet; that is the next step.
The same app, built for the desktop. We build and run it on Apple Silicon; Intel Macs are not built yet.
A desktop build with an ordinary window. Not distributed through stores yet.
The same desktop build as Linux and macOS, with a proper installer that updates itself without asking for administrator rights. It just is not in the Microsoft Store.
Nothing is tied to a phone number or an email. Nobody can take over your SIM with a forged letter, intercept a text message and walk off with your conversations - there is no number to take.
Nodryn never opens your contacts. You hand your address to the people you actually want to talk to. No cheerful "your friend just joined" from a list you never shared.
No trackers, no advertising code, no analytics. No company learns when you were online, who you talked to, or how long you stayed. Your accepted contacts do see when you were last around - that is what "last seen" is for, and it turns off in one tap.
An identity is just mathematics
On first launch your phone makes a pair of keys and shows you twelve words. Write them on paper, with a pencil. They are the only way back to your identity if you lose the phone. We do not have them and no server does - the only other copy sits inside your own phone, which is why the app can show them to you again.
We will not tell you "we see nothing" - that would be a lie. Here is what is actually visible:
- The relay sees which device is speaking to which - it could not forward a packet otherwise - plus the network address, the size and the time. It is not forbidden from reading the words. It simply has no way to.
- The mailbox: if you are offline, a sealed envelope waits on our node until your phone confirms it, and at most seven days either way. The envelope is visible. What is inside is not.
- The mailbox holds more than mail. Between messages it keeps your published keys, your list of devices and the address used to wake your phone - thirty days after you last touch that node. If you switch backups on, a sealed copy of your history sits there for up to a year. All of it is on the privacy page, with the exact clocks.
- Losing the twelve words: nobody on earth, us included, can reset anything by text message or bring your conversations back. We do not have your keys and cannot get them.
- Waking an iPhone: Apple draws the notification before our app runs, so the wake-up signal has to say which of three cards to draw - a message, an incoming call, or a missed one. Apple sees that, and never a name or a word. On Android the signal is literally empty.
- An unlocked phone: if someone picks up your device already unlocked, encryption does nothing at all. Lock your screen. That is the only thing that helps here.
