CloudEx Inc. ("we", "us", or "our") operates the "Keyboard Pro" app (the "Service"). This Privacy Policy explains what information we collect, how we use it, and the choices available to you. By using the Service, you are deemed to have agreed to the practices described in this Policy.
1. Our Core Principle
Keyboard Pro is a keyboard (input method) for Android. A keyboard handles everything you type, so we designed it around one rule: what you type never leaves your device. Converting what you type into words, suggesting candidates, and learning the words you choose all run on your device with a dictionary built into the app. We never view, collect, upload, or transmit what you type to our servers or to anyone else. There is no account and no sign-up. Specifically, we do not have access to any of the following:
- The text you type with the keyboard, including passwords, messages, and search terms
- The contents of your clipboard and your clipboard history
- Your snippets, your custom words, and the words the keyboard has learned
- The photos and videos you choose as keyboard backgrounds
These leave your device only through actions you take yourself, such as exporting your snippets to a file or sharing a theme you made (Section 2).
2. What You Type, Your Clipboard, and Your Content
- What you type: Keystrokes are turned into text on your device and written only into the text field you are typing in. The parts of the app that make up the keyboard and the conversion engine do not use the network at all.
- Learning: To put the words you use ahead of others, the keyboard remembers the words you choose and the word you typed next. This is stored only on your device. You can turn learning off, forget a single learned word by long-pressing it, or erase everything with "Reset learning".
- Clipboard history: While Keyboard Pro is your selected keyboard, the text you copy is added to a clipboard history on your device, so that you can paste it again later. Only text and web links are kept; copied images and files are not. You choose how long the history is kept, and you can delete single items or clear the history at any time.
- What is never recorded: In password fields, and in fields where the app asks keyboards not to learn (such as a browser's private/incognito mode), the keyboard does not learn what you type and does not record the clipboard. Clips that another app marks as sensitive (for example, passwords copied from a password manager) are not added to the history.
- Snippets and custom words: The snippets and words you register are stored on your device.
- Keyboard themes: When you choose a photo or video as a background, the app keeps its own copy inside the app's storage on your device. The photo picker gives the app access only to the items you pick; the app does not ask for access to your whole photo library.
- Text stamps: A text stamp turns the line you typed into an image on your device and hands it to the app you are typing in — the same app that would have received the text. If that app cannot accept images, the Android share sheet opens and you choose where it goes.
- Voice input: Keyboard Pro itself does not record sound and has no microphone permission. The microphone button only switches to a voice-input keyboard that is already installed and enabled on your device (such as Google voice typing). Listening and transcription are done by that keyboard, under its own privacy policy.
- When anything leaves your device: Only when you do it yourself: exporting snippets and custom words to a file, exporting or sharing a theme you made (the file contains the theme's settings and the background photo or video you chose), or sending a text stamp. We never receive any of it.
3. Information We Collect
3.1 Information Collected Automatically
- Anonymous crash reports: Via Firebase Crashlytics. When the app crashes, we collect the stack trace, device model, OS version, and app version, together with a random identifier that Firebase creates for each installation of the app. Crash reports never contain what you type, your clipboard, your snippets, or any other personally identifiable information.
- Purchase information: We use purchase tokens issued by Google Play to verify your one-time "Premium" purchase. We never receive any payment information such as credit card numbers.
- List of our other apps: To show our other apps, the app's settings screens (never the keyboard itself) download their names, descriptions, and icons from our content server (static files hosted on Cloudflare Pages). The request contains no personal data from the app. As with any request to a web server, the server receives your device's IP address as part of the connection. Tapping an app in the list opens its page on Google Play.
- This privacy policy page: When you open the privacy policy inside the app, the page is loaded from our web server, which receives your device's IP address as part of the connection, as with any web page.
The app contains no analytics SDK and no advertising SDK, and it does not use your device's advertising ID.
3.2 Information Stored Only on Your Device
- Clipboard history and learning: The text you copied and the words the keyboard has learned. They are stored only in the app's storage on your device and are excluded from Android backup and device-to-device transfer.
- Snippets and custom words: The snippets and words you registered.
- Keyboard themes: The themes you made, including the app's own copies of the photos and videos you chose.
- App settings: The languages you type in, the keyboard layout and height, sound and vibration, the selected theme, and similar settings.
- Android backup: If backup is turned on in your device settings, Android may include your settings, snippets, custom words, and the themes you made (including background photos, but not videos) in the backup it saves to your own Google account, and may copy them to a new phone when you transfer your data directly. Clipboard history and learning are always excluded. This is handled by Android; we have no access to it.
- When you uninstall: Uninstalling the app or clearing its data deletes everything above from your device. Files you exported yourself remain where you saved them.
3.3 Information We Explicitly Do Not Collect
- The text you type, including passwords and credit card numbers
- The contents of your clipboard or your clipboard history
- Your snippets, your custom words, and the words the keyboard has learned
- The photos and videos you choose as backgrounds
- Your name, email address, phone number, or contacts (the app has no account or sign-up)
- Your location
- Sound from the microphone
- The contents of your screen or of other apps, or which apps you use
3.4 Permissions and Access the App Uses
Keyboard Pro uses the following only for the stated purposes:
- Input method (keyboard) — To type with Keyboard Pro, you turn it on in your device's keyboard settings. When you do, Android shows a warning that a keyboard may be able to collect all the text you type, including personal data such as passwords and credit card numbers. Android shows this warning for every keyboard that is not preinstalled. Keyboard Pro handles what you type only on your device, as described in this Policy, and you can switch to another keyboard or turn Keyboard Pro off at any time.
- Clipboard — Android lets only the currently selected keyboard read the clipboard. Keyboard Pro uses this to keep the clipboard history on your device and to offer what you just copied for pasting.
- Vibration (VIBRATE) — Vibrates when you press a key. You can turn it off in the settings.
- Internet (INTERNET / ACCESS_NETWORK_STATE) — Used only for anonymous crash reports, Google Play purchase verification, in-app reviews and in-app updates, downloading the list of our other apps, and showing this privacy policy in the app. Typing, conversion, and every other keyboard function work without an internet connection, and what you type is never sent.
- Google Play billing (BILLING) — For the one-time Premium purchase.
The app does not request access to the microphone, camera, location, contacts, or your photo library.
4. How We Use Information
The limited information we collect is used only for the following purposes:
- Operating and maintaining the Service
- Verifying your Premium purchase
- Diagnosing and fixing crashes
- Responding to support inquiries
- Complying with applicable laws
5. Third-Party Services
Keyboard Pro uses the following third-party services. Each service has its own privacy policy.
- Firebase Crashlytics (Google LLC) — anonymous crash diagnostic data
- Google Play Billing (Google LLC) — the one-time Premium purchase; payment is completed on Google Play, and we receive only a purchase token
- Google Play In-App Review and In-App Updates (Google LLC) — let you rate the app and install updates without leaving it; handled by Google Play
- Cloudflare Pages (Cloudflare, Inc.) — hosts the static list of our other apps
We do not sell your data, and we do not share it with advertising networks.
6. Data Retention
- Crash reports: retained for 90 days, then deleted.
- Clipboard history on your device: kept for the period you choose in the app, or until you delete it. Pinned items are kept until you unpin or delete them.
- Learning, snippets, custom words, themes, and settings on your device: kept until you delete them, uninstall the app, or clear the app's data.
7. International Data Transfers
We are based in Japan. The infrastructure used for crash diagnostics and for hosting the list of our other apps may be located in various countries. When you use the Service, the minimal information described above may be processed outside your country of residence under standard contractual safeguards.
8. Your Rights
