Hides private details on a web page before you share your screen.

A Chrome extension (the Edge and Firefox versions use the same code). It blurs emails, phone numbers, card numbers, API keys and IBANs on the page you are about to show, and lets you blur any other part by clicking it.

Before and after

A demo billing page with customer emails, phone numbers, card numbers, IBANs and API keys in plain view
Hushpane off.
The same page with Hushpane on: emails, phones, cards, IBANs and API keys are blurred, names and plans stay readable

Real screenshots of the extension on a demo page (fake data). Names, plans and ordinary numbers such as "2026" and "$12,480.50" stay readable. Only the matches are blurred.

How you use it

  1. Open the page

    Go to the page you will share: a dashboard, an inbox, a billing screen.

  2. Turn blur on

    Click the Hushpane icon and switch on "Blur on this page", or press Alt+Shift+B. Your browser lets you change that shortcut.

  3. Share your screen

    The blur stays while the page changes. New emails or keys that appear are blurred too. Check your screen before you start sharing.

Free and Pro

Clicking to blur is free forever, with no account and no card. Everything else needs a Pro license.

Free

  • Click any part of a page to blur it
  • The on and off switch and the Alt+Shift+B shortcut
  • Free blurs disappear when you reload or leave the page

Pro ($4.99 a month or $47 a year, 3 browsers) and Team ($97 a year, 10 browsers)

  • Automatic blur of emails, phone numbers, card numbers, API keys and tokens, and IBANs, each one switchable
  • Draw a blur box over any area, including video, images and canvas
  • Blurs are saved per site and come back after a reload, on that page or on every page of the site
  • Blur strength from 2 to 20 px (12 px by default)
  • Hide the tab title and icon
  • Saved blurs sync through your browser's own sync

Every control sits in one panel. On Free, Pro controls stay visible with a lock and the words "Pro". Nothing is hidden behind a second menu.

Free: only "Click to blur parts" and the switch work. The rest is locked.

Pro: detector checkboxes, blur box, strength slider and tab hiding are on.

On browser pages it cannot change (settings, extension pages, local files) it says so.

Blur what the detector cannot know about

Pick mode: a revenue figure is blurred and the next row has a green outline under the pointer
Click to blur (Free). Choose "Click to blur parts". A green outline follows the pointer; click to blur that part. Keep clicking, then press Esc or Done.
A blur box drawn over a moving video area
Blur box (Pro). Choose "Draw a blur box" and drag over any area. It works over video and canvas, because a box covers the area without reading it.

What it detects (Pro)

Detection runs on the text of the page and in form fields. It looks for these patterns and checks them, so random numbers stay readable.

TypeHow it decides
EmailA normal address pattern, such as hello@example.com. Rejects broken ones like a..b@example.com.
Phone7 to 15 digits with a leading + or phone punctuation, such as +90 212 555 12 34. Bare order numbers are not treated as phones.
Card number13 to 19 digits that pass the Luhn check (the checksum every card number has).
API key and tokenKnown key formats such as Stripe (sk_live_, sk_test_), GitHub (ghp_, github_pat_) and AWS, plus JWTs and long random-looking tokens.
IBANCountry code and check digits, the exact length for that country, and the official mod-97 check.
Form fieldsIf a text, email, phone, search, URL, number or password field, or a text area, holds one of the above, the whole field is blurred.

What it does not do

Where your data goes

Page text is read only inside your browser and never stored or sent. There is no Hushpane account, server or analytics. The only network call is the license check with Polar, the payment provider.

Page text and form valuesRead and matched in your browser. Never stored.
Settings and saved blursSite, selector and box position stay in your browser. Pro saved blurs use browser sync, if sync is on.
PolarReceives the license key and activation label for a check about once a week. Nothing from the page itself.

After install

Hushpane welcome page with How it works, Free and Pro cards

Installing opens a welcome page. It shows the three steps, what Free and Pro include, and the reminder that blur is visual only.

Buying happens on Polar's checkout. The license key arrives right after purchase. Paste it into "License key" in the popup and press OK.

Each key works on a set number of browsers. If you reach that limit, the popup says so and points you to Polar's customer portal, where you can remove an old browser.

If a license check fails because of a network problem, Pro keeps working. Pro stops only when Polar says the license is no longer active, or when you remove this browser in Polar's customer portal. Click to blur stays free either way.

Screenshots come from the built extension (version 0.1.0) in Chromium on local demo pages with fake data. Last updated 13 October 2026.
