Where it helps, what you control, and questions

Made for the moments someone can see your screen.

A few everyday situations PeekShield was built for.

Co-working space

A stranger at the next desk

You’re on a hot desk with your client’s WhatsApp group open beside your work. Anyone glancing over sees a column of blurred names and messages. You hover the one line you need, read it, and move on.

Helps: Chat messagesNamesProfile pictures

Video call

Sharing your whole screen

You share your screen to walk the team through a document, and Slack and Messenger are one click away. If you flip to them by mistake, the room sees blur, not your DMs. You only reveal what you hover.

Helps: Blur strength: HighHover to reveal

Train, bus, café

Someone standing behind you

The chat list gives away the most: who you talk to and the start of every message. PeekShield blurs previews, names and pictures, so a person behind your seat can’t piece anything together.

Home

When nobody’s around

Alone at your desk and don’t need it? Press Alt + X (⌥ Option + X on a Mac) and everything reads normally. Press it again before you head out. The OFF badge on the icon reminds you if you forget.

Seven chat apps. One extension.

Most blur extensions cover one app, so you end up installing one for WhatsApp, another for Discord, another for Slack. PeekShield covers all of these with the same switches and the same shortcut.

Web versions only, not the desktop apps. Apps marked new are still being tuned. On Facebook, only chats are blurred; your feed is left alone.

See it in 40 seconds.

What it looks like in a real chat window: blurred by default, readable where you hover.

Watch on YouTube if you prefer, with captions.

The PeekShield popup on WhatsApp Web: a Protection switch, blur strength (Low, Medium, High), switches for chat messages, message previews, profile pictures, names, what you type, media viewer and status updates, and a Blur when I switch tabs option.

You decide what gets blurred.

Click the PeekShield icon in your toolbar. Every switch applies instantly, and your choices follow you to every supported app.

Chat messages
Message text, photos, videos, stickers and files in the open conversation.
Previews, names, pictures
The chat list: last-message previews, contact and group names, profile pictures.
What you type
Off by default. Blurs the message box until you click into it.
Blur strength
Low, medium or high. Low is enough for a glance; high hides shapes too.
Blur when I switch tabs
Blurs the whole chat page while it’s in the background, so tab previews and window switchers (Alt+Tab, Mission Control) show nothing readable.
Alt + X
⌥ Option + X on a Mac
Turns everything off or back on. A small OFF badge on the icon tells you when you’re unprotected.

Nothing leaves your device.

An extension that can see your chats has to earn your trust, so PeekShield is built to have nothing to send. It adds a stylesheet that blurs parts of the page. It never reads what the page says.

0network requests: no servers, analytics, error reports or update pings
2permissions: storage for your settings, activeTab to see which app you’re on
0accounts or sign-ups. Settings are saved in Chrome, like a bookmark

Chrome will say PeekShield can “read and change data” on the seven chat sites. That’s the wording for any extension that changes how a page looks; it’s how the blur gets applied. The full details are in the privacy policy.

Questions

How do I blur WhatsApp Web?

Install PeekShield, then open web.whatsapp.com. Messages, chat names, previews and profile pictures are blurred straight away, with nothing to set up. Hover over anything to read it, and press Alt + X to turn the blur off and on.

How do I hide my chats while sharing my screen?

Turn PeekShield on before the call, and set Blur strength to High in the popup so shapes are hidden too. Your chats stay blurred for everyone watching, and you can hover a single message when you need to read it. Switching on Blur when I switch tabs also hides the page in tab previews and window switchers.

Does it work on Discord, Slack and Telegram?

Yes. PeekShield works on the web versions of WhatsApp, Telegram, Discord, Slack, Messenger, Facebook chat and LinkedIn messaging, with the same switches everywhere. Support for Telegram, Messenger, Facebook and LinkedIn is newer and still being tuned.

Does PeekShield read my messages?

No. It only changes how the page looks, the same way a stylesheet does. It doesn’t read, store or send what’s on the page, and there’s no server it could send anything to.

Blurring stopped working on a tab I left open

Chrome pauses tabs you haven’t used for a long time, and PeekShield can also lose its connection to a tab if the extension updated while that tab was open. The switch still says on, but the page isn’t blurred.

A hard reload fixes it: press Ctrl + Shift + R on Windows and Linux, or ⌘ + Shift + R on a Mac. That reloads the page and PeekShield starts blurring again straight away.

Something isn’t blurred. How do I report it?

These apps update their pages often, and sometimes a change moves something out of PeekShield’s reach. Click the PeekShield icon, then Something not blurred? Report it at the bottom. It opens an email to me with the app name and versions already filled in.

It helps a lot to attach a short screen recording of where it happens, like opening group info or switching to a tab. If you can’t record, a screenshot works too. Before attaching, cover or crop anything private, since the part that wasn’t blurred may show real messages. A test chat is ideal.

Does it work in the WhatsApp or Discord desktop app?

No. PeekShield is a Chrome extension, so it works on the web versions: web.whatsapp.com, web.telegram.org, discord.com, app.slack.com, messenger.com, facebook.com and linkedin.com/messaging.

How do I read something quickly?

Hover over it. To turn everything off for a while, press Alt + X (⌥ Option + X on a Mac), and press it again to turn it back on. You can change the shortcut at chrome://extensions/shortcuts.

Why isn’t my Facebook feed blurred?

On purpose. PeekShield is for private conversations, so on Facebook it only blurs chats: the pop-up chat windows and the Messages page. Your feed is mostly public posts, and blurring it would make Facebook hard to use.

Will it slow down Chrome?

No. The blur is plain CSS, which the graphics card handles. Nothing scans the page or runs on a timer while you chat.

Is it free?

Yes, with no ads and no paid tier. If it’s useful to you, there’s a support link. It’s optional and changes nothing in the extension.
