Poketto · Your fourth-dimensional pocket
Poketto is a personal peer-to-peer sync and sharing space. Files travel directly between your devices — they are never uploaded to our servers, and there is no central storage.
You sign in with a 12-word recovery phrase (BIP39) as a self-sovereign identity, with no account and no registration. The same sign-in code opens the same space on your phone and your computer, and you can share folders or files by link for others to browse or collaborate on.
Your files travel straight between your own devices
Poketto is a space of your own that spans your devices. Files go from this device to that one directly, never through our servers, with no central storage. No sign-up, no email. And when you need to, you can hand one of those folders to someone else with a link.
Two ways people use it
One space, two completely different needs. Most people only need one of them; the other can wait until it comes up.
On your own: carry your files with you
You made something on your computer and want it on your phone or another machine, without uploading it to somebody else's cloud first.
- Sign in on every device with the same 12 words and it is the same space, with the same files and folders everywhere.
- Fetch a file the moment you need it. The whole space does not have to sync down first, so your phone's storage stays free.
- The file comes straight from your own other device, with no third party holding it in between.
With other people: hand something over
You want to give a whole folder to a colleague, a student or a friend without making them sign up, or the other way round: you need to collect what they send back.
- Create a share link and they can browse and download right away, with nothing to install and no account to make.
- Allow uploads and that folder becomes a shared inbox. You can also invite someone as a collaborator.
- While they are fetching, a device of yours holding that file has to be switched on. That is the price of peer-to-peer.
How it works
- Create a space
One click, and you get 12 words. Those 12 words are the key. We never see them and cannot reset them for you. - Put things in
Files stay on your own device. What the server keeps is the directory: names and folder structure. - Take them out anywhere
Sign in on another device with the same 12 words, or share a link. The bytes travel directly between the two devices.
What you can do with it
One space across devices
Your phone, the computer at home, the machine at work: the same phrase opens the same space, with the same files and folders.
Share by link
Share a folder or a file and the other person can browse it without signing up. You can also let them upload, turning it into a shared inbox.
Installable, and works offline
Install it as its own app (PWA). Anything already stored on this device opens with no network at all.
Take everything with you
Export the whole space as a single ZIP onto your own disk, and import it back later. You are never locked in.
How this differs from what you already use
This compares categories rather than individual products. The three differ on where your files sit, and most of the rest follows from that. The row where we come off worse is in there too.
| Poketto | Cloud drives (OneDrive, iCloud, pCloud and the like) | Nearby transfer (AirDrop and the like) |
|---|
| Where files sit | On your own devices | On the provider's servers | Nowhere; they only pass between two devices |
|---|
| Account needed | No. The 12 words are the key | Yes, you register an account | No, but only between devices of the same brand |
|---|
| Storage limit | As large as your own disk | Whatever the plan allows; more costs money | Not applicable, nothing is kept |
|---|
| Who holds your content | Your devices. The server holds only directory metadata and the text you type | The provider holds it; whether they can read it depends on each service's encryption | Only the sending and receiving device |
|---|
| What the other person does | Opens a link. No account, nothing to install | Usually opens a link; sometimes has to sign in | Needs a device of the same brand and has to be nearby |
|---|
| Distance and network | Anywhere, as long as both sides are online | Anywhere | Mainly two devices close to each other |
|---|
| When your device is off | They cannot fetch that file. This is our trade-off | Always available, because the file is on their machines | Nothing can be sent |
|---|
What it is not
Not a cloud drive
We do not have your files and have nowhere to put them. The storage you use is your own device's.
Not an account service
No registration, no password, no email, and therefore no personal data that could leak.
Not a backup service
The bytes live on your devices. If a device dies or a file is deleted, Poketto has no trash can to recover it from.
Not a storage plan
Since the storage is yours, there are no GB tiers and no usage billing.
Limits, stated up front
These three come from how peer-to-peer works. They are not faults, and you deserve to know before you commit.
The source device has to be online
For someone to fetch a file, a device holding those bytes must be switched on and connected. What they see is not a failure, it is simply not available right now.
A lost phrase cannot be recovered
With no account table there is no support desk that can reset anything. Write the 12 words down on paper. That is the only backup.
Needs a modern browser
Direct transfers use WebRTC. Very old browsers, or networks that block peer-to-peer connections, will fail to connect or fall back to a slower path.
Questions people ask
Does it cost anything?
No. The bytes never pass through us, so there is no storage bill to pass on to you.
Can you see my files?
Photos, videos, documents and the like never pass through us. They go straight from one device to another. What sits on our servers is the directory (names, folder structure and so on) and the text you type or edit inside Poketto. We keep that text so your other devices can still read it while your computer is off. Treat it as a notepad kept online and do not put passwords or secrets in it.
What happens when I close the browser?
The space is still there, with its file list and settings. But for someone else to fetch a file, a device holding those bytes needs to be online.
What if I lose the 12 words?
Nothing can be done. That is the price of having no account, and it is the same reason nobody else can open your space either.
