Stealth Keyboard BETA

Stealth Keyboard is a system-wide Android input method (IME) shipped inside Stealth. It is a full replacement keyboard with autocorrect, swipe-cursor on the spacebar, a voice dictation panel, an emoji panel, a media (GIF / image) panel, and direct access to your Stealth Clipboard. All preferences are stored locally; nothing typed on the keyboard is uploaded.

Enable the Keyboard

Open the Stealth Keyboard tool from the toolbar. The status card at the top tells you exactly which step you are on:

Enable in Settings

Tap the Enable in Settings button to jump to the Languages & input → Manage on-screen keyboards screen. Toggle Stealth Keyboard on and accept the system warning that input methods can read what you type. Stealth Keyboard does not transmit anything you type.

Choose Stealth Keyboard

Tap the Choose Stealth Keyboard button to open the input method picker, then select Stealth Keyboard - English (US).

Ready to Use

The status card now shows "Ready to use" with a check mark. The keyboard is active across your device. To switch back later, hold the globe key on any keyboard.

Permissions on first use: If you have the voice button enabled, the settings screen requests RECORD_AUDIO. If the emoji / media panel is enabled, it requests READ_MEDIA_IMAGES (or READ_EXTERNAL_STORAGE below Android 13). Both are optional — the keyboard still types text without them.

Layout & Typing Features

Autocorrect

Local on-device autocorrect engine. Suggestions are generated from a built-in dictionary — no text leaves the device. Tap a suggestion in the strip above the keys to commit it.

Period on Double-Space

Tap space twice at the end of a sentence to commit ". " automatically.

Swipe-Cursor on Spacebar

Slide your finger left or right across the spacebar to move the text cursor one character at a time. Useful for fixing typos without picking your finger up.

Sound & Haptics

Optional audible click and vibration feedback on each keypress.

Number Row

Optional persistent top row with the digits 0-9 so you do not have to switch layers for numbers.

Symbols Layer

Standard alpha / numeric / symbol layer switching with shift, capslock, and long-press accents on supported keys.

Built-In Panels

Three optional toolbar buttons sit above the letter keys. Each can be hidden in the settings screen.

Voice

Microphone button. Tap to dictate; the text is transcribed by Android's built-in SpeechRecognizer and inserted at the cursor. Recognition runs through whatever speech engine you have set as default in Android settings.

Emoji

Full Unicode emoji picker grouped by category, with a "Recent" tray populated from your usage. Tap an emoji to insert it.

Clipboard

Direct access to your Stealth Clipboard history (when the Clipboard tool is enabled). Tap an entry to paste it. With Cross-Device Clipboard Sync on, you can paste something you copied on Stealth for Windows just as easily as something you copied on this phone.

Stealth Clipboard Integration

The Clipboard panel reads from the same encrypted store as the Clipboard tool. There is one toggle in keyboard settings:

Show Clipboard button	Hide or show the clipboard panel button on the keyboard toolbar.
Use Stealth Clipboard sync	When on, the panel pulls from the cross-device synced clipboard. When off, the panel only sees clips captured locally on this phone.

If you have not enabled the Clipboard tool yet, the keyboard prompts you to enable it the first time you tap the clipboard button.

Appearance Controls

The Appearance section of the settings screen lets you tune the keyboard layout to your hand size. All values persist across reboots.

Key height	60% to 180% of the default. Default 112%.
Key font size	80% to 140% of the default label size. Default 100%.
Key width fill	80% to 130%. Higher values reduce the gaps between keys for an edge-to-edge look.
Horizontal spacing	0–8 dp gap between keys in the same row.
Vertical spacing	0–8 dp gap between rows.
Theme	Dark (matte charcoal) or Midnight (deeper black with purple accents).

Privacy Model

The IME process never sends your keystrokes off-device. There is no telemetry, no cloud autocorrect, and no learned-words upload.
Autocorrect uses a fixed on-device dictionary. It does not send anything to a server, and it does not learn from your typing across apps.
Voice dictation hands the audio to Android's SpeechRecognizer. Where the audio actually goes (on-device vs. Google's cloud) depends on the speech engine your phone has selected by default in system settings.
The Clipboard panel only reads encrypted clips already stored by the Clipboard tool. Sync (if enabled) goes through the same end-to-end encrypted Stealth Account API the Clipboard tool uses.
The keyboard does not ask for internet permission for itself. The clipboard sync that happens behind the scenes is performed by the Stealth app process, not the IME.

Switching Back to Another Keyboard

Hold the globe key on any keyboard to bring up the system input method picker, or open Android Settings → System → Languages & input → On-screen keyboard. Stealth Keyboard can be left enabled and unselected; in that state it sits idle and does not affect typing.

Troubleshooting

Status stuck on "Not enabled"	Re-open the system keyboard settings via the Enable in Settings button and confirm the toggle is on. Some OEM skins put the toggle behind a confirmation dialog.
Status says "Enabled, not selected"	Open the input method picker via Choose Stealth Keyboard and pick Stealth Keyboard. Android only switches the active IME when you explicitly select it.
Voice button does nothing	Microphone permission was denied. Long-press the Stealth app icon → App info → Permissions and re-enable Microphone, then re-open the keyboard settings.
Clipboard panel is empty	The Clipboard tool may be disabled or have no entries yet. Open the Clipboard tool and toggle Track Clipboard on, or copy something to seed the history.
Keys feel cramped or oversized	Tune Key height, Key width fill, and Horizontal/Vertical spacing in the Appearance section.
