A private keyboard

You type in your language. The app gets another.

PrivBoard finishes each word on your phone, translates it into a language picked from your own list, and hands only that to the app you are typing in. You keep reading your own words.

Languages in this demo

This demo runs in your browser and makes no network calls. Its phrase table is a small hand-written set of single words, not the app's dictionary.

Two views

What you see, and what the app gets

You see

Your own words, in your own language, in a preview bar on the keyboard. Backspace works as you expect.

The app receives

Each finished word, translated into a language chosen at random from the list you picked. A word you are still typing is never written to the app's text field.

Example

You see: hello my name is jason

The app receives: 你好 나의 nome 是 jason

Names and words the dictionary does not know stay as typed.

How it works

Three things that are true of the build

  • Words are finished, then translated on the phone

    When you end a word with a space or punctuation, the keyboard translates it on your phone and writes the result to the app. Nothing you type is sent to us or to a server.

  • The unfinished word is never sent

    The word you are still typing lives in memory and in your preview bar. The app's text field only ever receives complete words.

  • Passwords, emails and web addresses are left alone

    In password, email address, web address, number and phone fields, the keyboard passes your keys straight through. It does not hold them back or translate them.

Privacy

Privacy, stated carefully

These are the claims we can stand behind, and the limit you should know about.

Stays on your phone

  • What you type, while it is being processed.
  • Your settings: palette, languages, layout and keyboard options.
  • A background photo, if you choose one. It is copied into the app's private storage and never uploaded.

We never receive

  • Your keystrokes or the text you write.
  • The translated words.
  • An account, because there are no accounts.

What we do handle

  • Your subscription status, through the app stores and RevenueCat.
  • Messages you send to support.
  • Anonymous website statistics, only if you accept analytics cookies on this site. The app and keyboard have no analytics.
  • The Android keyboard downloads translation language packs from Google. Those requests carry no text you typed.

The honest limit: this is not encryption

PrivBoard hides your text from people looking over your shoulder and from apps that read the text field. It is not encryption. Anyone who understands the languages involved can still read the result, and the app you type into keeps whatever it receives.

Make it yours

Palettes, layouts, hidden letters and backgrounds

These keyboards are drawn in your browser from the same colors the app uses. They are drawings, not screenshots.

Palette
Layout
Hidden letters

Blank keys hide the letters from onlookers. Screen readers still announce each key.

Background

Choose your own photo from the system picker in the app. It stays on the phone.

Light and dark follow your phone unless you pick one.

FAQ

Questions we can answer from the product

Does it send what I type anywhere?

No. Typing is processed on your phone and is not stored or sent to us or to any server. The app you type into does receive the translated words, and what it does with them is up to that app. The Android keyboard also downloads language packs from Google, and those requests carry no text you typed.

What happens to passwords?

Password, email address, web address, number and phone fields are passed straight through. The keyboard does not buffer or translate them.

Can people still read the result?

Yes, if they understand the languages involved. PrivBoard hides text from onlookers and from apps that read the field. It is not encryption.

What if I cancel?

When the subscription ends and a short grace period of 3 days has passed, the keyboard shows a locked panel with a key to switch to another keyboard, so you are never stuck. Your settings stay on your phone.

Is there a free version?

No free tier. There is a 3 day free trial, then the subscription renews automatically until you cancel in the store.

Which phones does it work on?

Android first. An iPhone keyboard is planned and has no date yet.

How do I remove it?

Switch to another keyboard from the keyboard switcher, then uninstall PrivBoard like any other app. Your settings live on the phone and go with it.

Do you track me?

The app and the keyboard have no analytics. This website uses Google Analytics only if you accept it in the cookie banner, and you can change your mind from Cookie settings in the footer.

Type the way you always do. Share something else.

PrivBoard is for people who want what they type to stay readable to them and less readable to everyone else.
