Sharing your screen on a video call without showing private photos

You’re presenting to a client, helping a relative with a form, or showing friends holiday photos on a group call. You tap share, and a second later a message preview slides in, or you scroll one photo too far, or the gallery opens on a memory you’d forgotten. Everyone saw it. Screen sharing is built to show exactly what’s on your screen, and that includes everything you didn’t plan.

A few habits make it almost impossible to show the wrong thing.

What to do now

Share one app or window, not the whole screen. On a computer, call apps let you choose a single window or browser tab. On recent Android versions, you can choose to share one app instead of the entire screen. Whatever you open outside that window or app isn’t shown.

Turn on Do Not Disturb before you share. On Android, swipe down and tap Do Not Disturb, or set it up under Settings, then Modes or Do Not Disturb. Banners stop appearing while it’s on. Many phones also hide notifications while sharing automatically, but don’t rely on it.

Close what you don’t need. Gallery, messages, email, banking. A closed app can’t be opened by accident and won’t show up when you switch.

Prepare pictures before the call. If you’ll show photos, put just those in one album or folder first, or send them in the chat. Scrolling your whole gallery in front of others is how private photos appear.

Mind the previews. The recent apps screen shows a picture of each app’s last screen. If you share your whole screen and open recent apps, everyone sees those pictures.

Stop sharing before you browse. If you need to find something mid-call, stop sharing, find it, then share again.

Check what’s shared once you start. Most call apps show a small preview or a coloured border around what’s being shared. Glance at it in the first few seconds, so you know whether others see one window or everything.

If something private showed

Stop sharing straight away. Saying “sorry, wrong screen” is usually enough to move on. If the meeting was recorded, ask the host to trim or delete it. If the photo was something that could cause you harm, see the steps in keeping evidence of harassment for what to keep, and talk to someone you trust.

What doesn’t help

• Turning the screen brightness down. Brightness doesn’t affect what is shared.
• Hiding photos only from memories. It stops the surprise memory, but the photos are still in your main grid. See hide photos from memories on Android.
• Trusting you’ll be quick. Most slips happen in the first seconds of sharing, before you’ve got your bearings.
• Using a photo widget on your home screen. If you share the whole screen and go home, the widget is shared too. See a private photo on your lock screen.

Where a vault helps

A vault keeps private photos out of the places a shared screen reaches: the main gallery, memories, widgets and the photo picker. Silo, coming soon to iPhone and Android, keeps imported photos encrypted inside the app, opens only with its own PIN, and shows a cover in the app switcher instead of your last photo. On Android, Silo can also block screenshots and screen capture of its own screens. On iPhone, the phone doesn’t let apps do that, so don’t open Silo while sharing.

You can still use Silo albums to gather the photos you mean to show, then share them deliberately, one at a time.
