Enable Incognito Keyboard on Signal: How-To
Signal’s incognito keyboard option hides the text you type from your phone’s keyboard app, preventing it from learning your words or showing suggestions. You can turn it on in Signal’s Privacy settings, and it works on both Android and iPhone. This guide shows you exactly where to find the setting and what it does once enabled.
What Incognito Keyboard Actually Does
When you type in Signal, your keyboard app (like Gboard, SwiftKey, or the default Samsung keyboard) normally sees every word you type. It uses that data to learn your typing habits, suggest words, and store what you write in its own dictionary. Incognito keyboard tells Signal to temporarily disable that learning and suggestion feature for the text field you’re using.
Signal does this by setting a flag on the text input that the keyboard app respects. Most modern keyboards recognize this flag and switch to a “private” or “incognito” mode for that field. In that mode, the keyboard stops saving new words, stops showing predictive suggestions, and does not send what you type to its cloud services for syncing.
It is important to know what this does not do: it does not encrypt your messages (Signal already does that), it does not hide your screen from people looking at it, and it does not stop the keyboard from seeing the text in the first place. The keyboard still receives the characters you press; it just doesn’t store or learn from them.
How to Enable It on Android
On Android, the setting is inside Signal’s privacy menu. The exact path has stayed consistent across recent versions:
- Open Signal and tap your profile icon in the top-left corner.
- Tap Settings.
- Tap Privacy.
- Scroll down to the Incognito keyboard toggle.
- Turn it on.
Once enabled, every text field in Signal (chat input, search bar, profile editing) will send the incognito flag to your keyboard. You don’t need to restart the app or re-enable it per conversation. If you later switch keyboards, the setting stays on because it lives in Signal, not in the keyboard.
How to Enable It on iPhone
On iOS, the setting is in the same place but under a slightly different menu name. Recent Signal versions for iPhone label it Incognito Keyboard under Privacy as well:
- Open Signal and tap your profile icon in the top-left.
- Tap Settings.
- Tap Privacy.
- Find Incognito Keyboard and toggle it on.
Note that iOS keyboards are more restricted than Android ones. Apple’s built-in keyboard does not offer a separate incognito mode, so this toggle mainly affects third-party keyboards like Gboard or SwiftKey that support the private mode flag. If you use the default Apple keyboard, the setting may have little visible effect because Apple’s keyboard doesn’t learn from Signal fields anyway in a way that you can turn off.
Why You Might Want It On
People enable incognito keyboard for a few practical reasons:
- Privacy from keyboard apps: If you use a keyboard that syncs your typing data to the cloud (for personalization), incognito mode stops Signal messages from being part of that data.
- Shared devices: If you hand your phone to someone else to read a message, they won’t see your keyboard’s next-word suggestions based on your private conversations.
- Avoiding embarrassing suggestions: Typing a sensitive word once can make it appear as a suggestion later in front of others. Incognito prevents that.
- Reducing digital footprint: Even if you trust your keyboard, you may prefer that your most private chats leave no trace in the keyboard’s local dictionary.
The trade-off is convenience. With incognito on, you lose predictive text and auto-correction in Signal. If you type fast and rely on suggestions, you may notice more typos. You can toggle it off at any time without losing any data.
Common Problems and Fixes
If you turn on incognito keyboard but still see suggestions, check these things:
- Keyboard doesn’t support it: Not all keyboards honor the incognito flag. Samsung’s default keyboard, for example, may ignore it. Try a keyboard that explicitly supports private mode, like Gboard or SwiftKey.
- Keyboard is in a different mode: Some keyboards have their own incognito toggle that overrides the app’s request. Make sure the keyboard’s own private mode isn’t turned off.
- You’re testing in the wrong field: The setting applies to Signal’s text inputs, not to other apps. Open a chat and type to see the effect.
- Old Signal version: If the toggle is missing entirely, update Signal from your app store. The feature has been present for years, but older versions may have it under a different name.
If you still get suggestions after checking all that, you can manually clear your keyboard’s learned words in the keyboard’s own settings, but that is separate from Signal’s incognito toggle.
Does It Affect Signal’s End-to-End Encryption?
No. Incognito keyboard is purely about the keyboard app’s behavior on your device. Signal’s end-to-end encryption protects messages in transit between your phone and the recipient’s phone. That encryption is always on and cannot be turned off. The incognito keyboard setting does not change how messages are encrypted, stored, or delivered.
A common misconception is that incognito keyboard somehow makes your messages more secure or more private from Signal itself. It doesn’t. Signal never sees your messages in plain text, regardless of this setting. What it does is limit how much your keyboard learns about you. If you’re worried about a keyboard app logging your keystrokes, this setting is a useful extra layer, but it is not a substitute for trusting the keyboard you’ve installed.
Frequently Asked Questions
Does incognito keyboard work with all keyboards?
No. It only works with keyboards that support the private mode flag that apps send. Gboard and SwiftKey support it on both Android and iOS. Some default keyboards, like Samsung’s, may ignore it. If you don’t see a change, try a keyboard that explicitly advertises incognito or private typing.
Will incognito keyboard stop Signal from seeing my messages?
No. Signal already cannot see your messages because of end-to-end encryption. The incognito keyboard setting only affects your keyboard app’s ability to learn from what you type. Signal’s servers never receive plaintext messages, so there is nothing extra to hide from Signal itself.
Does turning on incognito keyboard disable emoji suggestions?
Yes, in most cases. When a keyboard enters private mode, it typically disables all predictive features, including emoji predictions and next-word suggestions. You can still manually open the emoji picker and choose one, but the keyboard won’t suggest emojis based on your text.
Can I turn incognito keyboard on for only some chats?
No. The setting is global in Signal. It applies to every text field in the app. There is no per-chat or per-contact toggle. If you want it on for one conversation, you have to have it on for all of them.
Does incognito keyboard affect auto-correct?
Yes. Auto-correct is usually disabled or significantly reduced in private mode because the keyboard doesn’t learn your corrections. You may see more typos if you rely on auto-correct. You can still manually correct words, but the keyboard won’t remember those corrections.
Is there a way to see if incognito keyboard is active?
Some keyboards show a small indicator, like a lock icon or a different color scheme, when in private mode. Gboard, for example, may show a small “incognito” icon. If your keyboard doesn’t show anything, you can test by typing a nonsense word twice; if it doesn’t appear as a suggestion the second time, incognito is likely working.
