  • My tools

    Always synced: the tools on your board, their order and size.

  • The windows open on your start page, including what you typed in them.

  • Every note in the notepad – on the notepad page, on your board and in windows.

  • Every list of website shortcuts – on the shortcuts page, on your board and in windows.

  • Every grid in the cover grid maker – on its page, on your board and in windows.

  • Every list of bookmarked organisations in the OIN lookup – on its page, on your board and in windows.

  • Keeps your pipeline and saved recipes on all your devices. Your files are never synced – only the steps and settings.

Turning something off removes it from your account straight away. Your devices keep their own copy.

Notifications

Tools that can tell you about something new while a Synsi tab is open, even when you are in another tab or app. Choose them for this browser.

This browser cannot show notifications from websites.
Notifications are blocked for this site. Allow them in your browser’s site settings (the icon left of the address), then switch them on here.
  • Says “New message” while a Synsi tab is open – never who wrote it or what.

Your choice is stored in this browser only. Notifications never show personal content such as a message or a number. They work while a Synsi tab is open; closed tabs get none.

Private messages with a number, not your phone number

Get a virtual number, share it with someone you know, and write to each other from any browser. No app, no email address, no phone number.

Not end-to-end encrypted: messages are stored encrypted on our server and deleted after a set time. See the privacy notes below.

Create your number

Choose a number

6 to 12 digits. Avoid easy ones such as 123456 or your birth year.

A forgotten PIN cannot be recovered

We do not ask for an email address or phone number, so there is no way to reset your PIN. If you forget it and are signed out everywhere, the number and its messages are lost.

Messages are deleted after 30 days. Your number is not linked to your name, email or phone number.

Sign in

Leave this off on a shared or public computer: you are then signed out when the browser closes or after two hours without use.

Your number

No connection – new messages will appear when you are back online.

No conversations yet. Enter the number of someone you know to start one.

No messages yet.

You blocked this number. Unblock it to write to each other again.
This number can no longer be reached.

Account & privacy

Your number

Give this number only to people you know, in person or through a channel you trust. Anyone with your number can write to you; block them if you no longer want that.

What we keep

Change PIN

Your other devices are signed out when you change your PIN.

Signed-in devices

Blocked numbers

You have not blocked anyone.

Delete your number

Deletes your sign-ins and the messages you sent, for good. Your number is never given to anyone else. The people you wrote to keep the messages they sent you until they expire.

How to use the VeilChat

  1. 1 Press “Create a number”, pick one of the suggested numbers (or choose your own) and set a PIN of at least six digits. No name, email address or phone number is asked.
  2. 2 Give your number to someone you know – in person, or through a channel you trust. They create their own number the same way.
  3. 3 Enter their number under “Write to a number” and send a message. They see it the next time they open VeilChat, on any device where they sign in.
  4. 4 Use “Account & privacy” to copy your number, change your PIN, see and sign out your devices, unblock numbers, or delete your number for good.

Messaging without handing out your phone number

A phone number says a lot: it is tied to your name at the provider, it travels with you for years, and once someone has it, every messaging app can find you with it. Sometimes you want to stay in touch with someone – a new acquaintance, a seller, a group of volunteers – without giving them that. VeilChat gives you a virtual number for exactly that: a short number that only works here, is not linked to your phone, and can be deleted when you no longer need it.

How it works

You create a number and a PIN. You tell the number to someone you know; they write to it from their own VeilChat number. There is no directory and no search: nobody can browse numbers or find you by name, and the only way to reach you is to have been given your number. Messages are text only, and you read them in the browser – on your phone, a laptop or a work computer – without installing anything.

What VeilChat protects – and what it does not

  • Pseudonymous, not anonymous. Your number is not linked to your name, email or phone number, and we do not ask for them. But our server sees your IP address while you use it (for security and rate limits), and the person you write to may of course know who you are.
  • Encrypted on our server, not end-to-end. Messages travel over HTTPS and are stored encrypted. That protects them in database copies and backups, but it is not end-to-end encryption: technically, Synsi could read stored messages. We open a message only to handle a report about it.
  • Deleted after 30 days. Messages disappear automatically after 30 days, on every device. Backups may hold a copy a little longer until they are replaced.
  • Your PIN is the only key. Because there is no email address, a forgotten PIN cannot be reset. Choose one you will remember – and not 123456 or your birth year: easy PINs are refused, and repeated wrong attempts lock the number for a while.

Blocking and reporting

If someone you gave your number to becomes a nuisance, block them: they can no longer send you anything, and they are not told that they were blocked. You can also report a number or a single message. A report keeps a copy of that message for our moderators for at most 90 days; reading it requires a recorded reason.

Frequently asked questions

Do I need a phone number or an email address?

No. You only choose a virtual number and a PIN. VeilChat does not ask for your name, email address or phone number.

Is VeilChat anonymous?

It is pseudonymous: your number is not linked to who you are. It is not fully anonymous – our server sees your IP address while you use it, and the people you write to may know you.

Is VeilChat end-to-end encrypted?

No. Messages are sent over HTTPS and stored encrypted on our server, but Synsi could technically read them. We only do so to handle a report.

What happens if I forget my PIN?

It cannot be reset, because we have no email address or phone number to verify you. If you are still signed in on a device, change it there under Account & privacy; otherwise the number is lost.

How long are messages kept?

30 days. After that they are deleted automatically, on every device.

Can strangers find me?

No. There is no directory or search. Only people you gave your number to can write to you, and you can block any of them.
