Curtain · privacy for your keyboard
Type in public.
Keep it yours.
Open your keyboard and a curtain falls over everything above it, so the person next to you can't read your chat. Your own text stays faintly readable. Hold to peek, let go to hide.

- Free core, no ads
- Android 8.0+

See it in 40 seconds
The curtain falls while you type.
In motion
See every curtain at work.
Veil and peek
Tap Veil and everything above the keyboard goes dark. Hold anywhere to look underneath.
Slit and passwords
Slit mode keeps only your typing line in view (Pro). Password fields curtain themselves.
Colours, tilt, setup
Pick a colour, turn the phone away to drop the curtain (Pro), and set it all up in three taps.
Ready on Home
One switch arms it. Modes, colours and opacity live on one screen.
How it works
A curtain that falls where the glances land.
Curtain doesn't replace your keyboard or dim the whole day. It waits until you type, then covers only what a neighbour could read.
- 01
Open your keyboard
A small pill docks on the keyboard's edge, clear of your send button. Drag it wherever suits your thumb.
- 02
Tap the pill
The curtain falls over everything above the keyboard. Your chat is hidden from the seat next to you.
- 03
Hold to peek
Press and hold anywhere to lift it for a moment. Close the keyboard and the curtain goes with it.
What's inside
Small, quick, and honest.
A curtain, not a dim screen
It falls only while you type, over everything above the keyboard, status bar included. Close the keyboard and it lifts.
Hold to peek
Press anywhere on the curtain and it lifts while you hold. Let go and it falls again. Optional touch-through lets you use the app underneath.
Password fields curtain themselves
Curtain notices the password flag on a field and falls on its own. It never sees what you enter.
Any keyboard, any app
No new keyboard to learn. The pill docks on the edge of the keyboard you already use, stays clear of your send button and remembers where you parked it.
Put the controls away
Drag the pill onto Hide here to put it away for an hour, the rest of the day or a day. A quiet notification brings it back with one tap.
Tells you if it stops
If Android switches Curtain off or closes it, you get a Curtain is paused card and one notification with a Turn on button.
Whole-screen curtain
No keyboard needed: cover the whole screen from the notification, a Quick Settings tile or the widget.
Your colour, your opacity
Pick the curtain colour and how opaque it is. The default keeps your own text faintly readable.
Stays on after a restart
Armed once, ready again after a reboot. A per-brand guide helps phones that stop background apps.
Slit mode (Pro)
Cover everything except the single line you are typing in, for the most crowded commutes.
Tilt to curtain (Pro)
Turn the phone away or face down and the curtain drops by itself. It reads the motion sensor only while you type.
Privacy
It reads where the keyboard is. Never what you type.
To know when your keyboard opens, Curtain uses an Android accessibility service. It is used for that and nothing else, and the app explains it in plain words before you switch it on.
Curtain reads
- Where the keyboard sits on screen
- Which app is open
- Whether the focused field is a password field
Curtain never reads
- The text you type
- What is inside a field
- What is on your screen
Curtain is software, not a polarising filter. It hides your screen from a glance, and does not stop screenshots, recordings or cameras.
Questions
Everything people ask first.
What is Curtain?
Curtain is an Android app that hides your screen from people next to you while you type. When the keyboard opens, a small pill appears on it. Tap it and a curtain covers everything above the keyboard, so a neighbour in a metro, bus, queue or open office can't read your chat. Your own text stays faintly readable, and you can hold anywhere to peek.
Does Curtain work with any keyboard?
Yes. Curtain does not replace your keyboard. It sits above whichever one you use, such as Gboard, Samsung Keyboard or SwiftKey, and falls only over the part of the screen above it.
Can Curtain read what I type?
No. Curtain reads three things only: where the keyboard is on screen, which app is open, and whether the focused field is a password field. It never reads the text you type, the contents of a field, or what is on your screen.
Why does Curtain need an accessibility service?
Android only tells an app where the keyboard is, and when it opens or closes, through its accessibility service. Curtain uses that service for the keyboard's position, the foreground app and the password-field flag, and for nothing else. Before you switch it on, the app shows a plain-language disclosure of exactly what it reads.
Does Curtain stop screenshots or cameras?
No. Curtain is software, not a polarising filter. It hides your screen from a glance over your shoulder. It does not block screenshots, screen recordings or a camera pointed at the phone.
Is Curtain free?
The core curtain is free, with no ads: the keyboard curtain, hold to peek, password fields, the whole-screen curtain, colours and the widget. Curtain Pro is a one-time purchase with a 14-day free trial and adds slit mode, a schedule, automatic curtains in chosen apps, decoy screens, pill looks and tilt to curtain.
What if Curtain stops working?
It tells you. If its accessibility service is switched off, or the phone closes it in the background, Curtain shows a Curtain is paused card with one Turn on button, opens a short guide the next time you open the app, and sends a single notification with a Turn on button, at most once a day until it is fixed.
Can I move or hide the controls?
Yes. The small pill docks on the edge of your keyboard and stays clear of your send button. Drag it anywhere and Curtain remembers the spot for that app, or drop it on Hide here to put it away for an hour, the rest of the day or a day.
What data does Curtain collect?
Curtain uses Firebase Analytics and Crashlytics to see which setup steps people get stuck on and to fix crashes, tagged with phone brand, Android version and keyboard family. It never logs what you type, field contents, screen contents or which apps you pick. A Share usage and crash data switch in Settings turns it off. The full policy is on the privacy page.
When can I get Curtain, and which phones does it support?
Curtain is on Google Play for phones and tablets with Android 8.0 or newer. Search for Curtain: Privacy Screen Guard, or open https://play.google.com/store/apps/details?id=ai.lazycode.curtain.
