CloudEx Inc. ("we", "us", or "our") operates the "Invoice Maker 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
Invoice Maker Pro lets you create invoices, estimates, delivery notes, receipts, and purchase orders, send them as PDF files, and photograph the receipts you receive for your expenses to keep track of them. Creating documents, making PDF files, reading receipts, and calculating totals all run on your device. Your business records are yours: they are stored on your device, and we never view, collect, upload, or transmit them to our servers. There is no account and no sign-up. Specifically, we do not have access to any of the following:
- Your business information, such as your business name, address, phone number, email address, tax registration number, and bank account details
- Your logo, seal (stamp), and signature images
- Your clients' names, addresses, email addresses, phone numbers, and other details
- The documents you create, their items and amounts, and your payment records
- Your expenses, your receipt images, and the text read from your receipts
Your data leaves your device only through actions you take yourself, such as sending a PDF file, printing, exporting, or saving a backup to a place you choose (Section 2), and through Android's own backup if you have turned it on (Section 3.2).
2. Your Documents, Receipts, and Business Information
- Where your data is kept: Your documents, clients, items, expenses, business information, and settings are stored in the app's own storage on your device. Your receipt images and your logo, seal, and signature images are also stored in the app's own storage. They are not added to your device's gallery, and other apps cannot open them.
- Photographing receipts: The receipt scanning screen is provided by Google Play services (ML Kit Document Scanner). The app itself does not have permission to use the camera; it receives only the finished image. You can also choose photos with Android's photo picker, which gives the app only the photos you select, or share images to the app from other apps.
- Reading receipts: The app reads the total, date, store name, registration number, and tax rate from a receipt image with ML Kit text recognition, which runs on your device. Receipt images and the text read from them are never sent to us or to Google. Google Play services downloads the language data used for text recognition to your device. To provide and improve these features, ML Kit may send Google statistics about how they perform and are used; these statistics do not include your images or the text read from them.
- Information about other people: Your documents and your client list contain information about your clients and the people who work for them, such as names, addresses, email addresses, and phone numbers. You are responsible for handling this information in accordance with the laws that apply to you.
- When anything leaves your device: Only when you do one of the following yourself:
- Share a PDF file or a receipt image, or send a PDF file by email. The app opens the app you choose (for example, your email app) with the file attached. Nothing is sent until you send it from that app.
- Print a document. The PDF file is passed to the printer or print service you choose.
- Save a PDF file, export a CSV file, or back up your data to a ZIP file in a location you choose.
- Turn on "Back up to a folder every day". Once a day, the app saves a ZIP file with your data and images to the folder you chose. If that folder is in a cloud storage service (such as Google Drive), the file is stored by that service.
- Tap a client's phone number or address. The phone number is passed to your phone app, or the address to the map app you choose.
- Contact us or send us feedback from the app. The app opens your email app with our address and adds your app version, Android version, and device model to the message. You can check and edit the message before you send it.
- Widgets, the Quick Settings tile, and notifications: The "Unpaid invoices" widget (Premium) shows the total still to be paid and the number of overdue invoices on your home screen. The "Scan receipt" tile shows this month's expense total in Quick Settings (Android 10 and later). Payment reminders show the client's name, the document number, the amount, and the due date. These are shown on your device's screen even when the app lock is on.
- App lock: If you turn on "Lock the app", the app asks for your device's screen lock (fingerprint, face, PIN, pattern, or password) when you open it. Android performs this check; the app only learns whether it succeeded and never receives your fingerprint, face data, or PIN.
3. Information We Collect
3.1 Information Collected Automatically
- Anonymous crash reports: Via Firebase Crashlytics. When the app crashes, we collect technical information such as the stack trace, device model, OS version, and app version. Crashlytics also records when each session of the app starts, so that we can see how many users are affected by crashes. These reports are linked to a random identifier created for the app installation, not to your name or account. They do not include your documents, clients, expenses, receipt images, business information, or any other personally identifiable information.
- Purchase information: The app uses the purchase token issued by Google Play to confirm your one-time "Premium" purchase with Google Play, and keeps the result on your device. Payment is completed on Google Play. We never receive any payment information such as credit card numbers.
- List of our other apps: To show our other apps, the app downloads 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. Which apps to show is decided on your device, using the country of your SIM card or mobile network, your language settings, and whether our other apps are already installed; this information is not sent. Tapping an app in the list opens its page on Google Play.
3.2 Information Stored Only on Your Device
- Your business information: Your business name, contact person, address, phone number, email address, website, registration number, and bank or payment details, together with your logo, seal, and signature images, are stored on your device and used only to print them on your documents.
- Documents, clients, and items: Your documents (with their items, amounts, taxes, notes, and payment records), your clients' details, and your saved items (the app remembers the items you use) are stored on your device.
- Expenses and receipts: For each expense, the date, amount, store, category, payment method, tax rate, registration number, memo, receipt images, and the text read from the receipt are stored on your device. With Premium, the app suggests the category you chose before for the same store, based on the expenses on your device.
- Daily backup inside the app: Unless you turn it off, the app saves a copy of your data (without images) in its own storage once a day and keeps the latest 7 copies. Before you restore a backup, the app also saves a copy of the current data so that you can go back.
- Trash: Documents, expenses, and clients that you delete are kept in the trash for 30 days so that you can restore them, and are then deleted permanently. You can also delete them from the trash yourself at any time.
- App settings: Settings such as document numbering, tax handling, currency, PDF design, reminders, and the app lock are stored on your device.
- Android backup: If backup is turned on in your device settings, Android may include your documents, clients, items, expenses, business information, logo, seal, and signature images, and settings in the backup it saves to your own Google account. Receipt images and the daily backups inside the app are not included in that backup. When you transfer your data directly to a new phone (by cable or wirelessly), receipt images are copied as well (Android 9 and later). This is handled by Android and Google; we have no access to it.
- When you uninstall: Uninstalling the app or clearing its data deletes everything stored in the app's own storage, including receipt images and the daily backups inside the app. Files you exported or saved to a folder you chose, and the Android backup in your Google account, are not deleted by this.
3.3 Information We Explicitly Do Not Collect
- Your business information, documents, clients, items, expenses, receipt images, or the text read from your receipts
- Your name, email address, or phone number, unless you send them to us by email (the app has no account or sign-up)
- The contacts on your device (the app never reads your contacts)
- Your location
- Your device's advertising ID (the app does not use it)
- A history of the websites you visit or the contents of your communications
- The contents of your screen or of other apps
3.4 Permissions the App Requests and Their Purposes
Invoice Maker Pro uses the following permissions only for the stated purposes. It does not request access to the camera, your photos and files, your contacts, or your location.
- Notifications (POST_NOTIFICATIONS, Android 13+) — Shows payment reminders before an invoice is due and when it is overdue, and lets you know when a recurring invoice has been created as a draft (both Premium). A reminder has a button to mark the invoice as paid. Requested after you unlock Premium, or when you turn these notifications on.
- Run at startup (RECEIVE_BOOT_COMPLETED) — Schedules your reminders again after your phone restarts, and shows any reminders that came due while it was off.
- Biometrics (USE_BIOMETRIC / USE_FINGERPRINT) — Used only if you turn on the app lock, to ask for your device's screen lock (fingerprint, face, PIN, pattern, or password). The app never receives biometric data.
- Google Play billing (com.android.vending.BILLING) — Lets you buy Premium through Google Play.
- Internet and network status (INTERNET / ACCESS_NETWORK_STATE) — Used only for anonymous crash reports, Google Play purchases, in-app reviews and in-app updates, downloading the list of our other apps, and showing this privacy policy in the app. The app never uses the internet to send your documents, clients, expenses, or receipt images. Creating documents and PDF files does not require an internet connection.
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
Invoice Maker Pro uses the following third-party services. Each service has its own privacy policy.
- Firebase Crashlytics (Google LLC) — anonymous crash diagnostic data
- ML Kit (Google LLC, through Google Play services) — the receipt scanning screen (Document Scanner) and on-device text recognition
- Google Play Billing (Google LLC) — the one-time Premium purchase; payment is completed on Google Play, and we never receive payment information
- 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
Invoice Maker Pro does not display ads within the app and does not share your data with advertising networks. The card and the list of other apps in the app's settings show only apps made by us. We never sell your data.
6. Data Retention
- Crash reports: retained for 90 days, then deleted.
- Support emails: retained for 12 months after the last reply, then deleted (except where legally required).
- Data on your device: kept until you delete it, uninstall the app, or clear the app's data. Items in the trash are deleted automatically after 30 days. The app keeps the latest 7 daily backups inside the app and deletes older ones automatically, so data you delete may remain in those copies until they are replaced by newer ones.
- Backups and exported files: the app keeps its daily backup files for the latest 7 days in the folder you chose and deletes older ones; other files in that folder are not touched. Files you export are kept wherever you saved them until you delete them.
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
Depending on where you reside (e.g., the EEA, UK, California, Japan), you may have the right to request access to, correction of, or deletion of the limited information we hold. You can:
- Edit or delete your documents, clients, items, and expenses in the app at any time, and empty the trash to delete them permanently
- Export your data at any time as CSV files, or as a ZIP backup that includes your images
- Uninstall the app or clear its data to erase the data stored on your device
- Turn off notifications or the app lock at any time, and turn off Android backup in your device settings
- Contact us at the address below to make a request regarding the information we hold
9. Children's Privacy
Invoice Maker Pro is not directed to children under the age of 13 (or the minimum age applicable in your region). If we inadvertently collect information from such a child, we will delete it promptly upon being contacted.
10. Changes to This Policy
This Privacy Policy may be updated from time to time. The latest version is always published at this URL together with its effective date. We will also notify you within the app of significant changes as appropriate.
