Privacy Policy

Last Updated: October 18, 2026

Camera Calculator & Expense Manager (“the App,” “we,” “us,” or “our”) provides camera-based number recognition, calculations, voice input, receipt scanning, and expense-management features.

This Privacy Policy explains what information the App processes, why it is processed, where it may be stored, and the choices available to users.

1. Information Stored on Your Device

The App may store the following information locally on your device:

• Calculation history and detected numbers

• Expense and income records

• Receipt details and locally saved receipt-image paths

• Categories, budgets, currency preferences, and app settings

• Subscription status

• Scan counts and allowance start dates

You can delete individual records or clear supported history through the App. Protecting locally stored information also depends on your device’s security settings, such as its screen lock and encryption.

2. Camera and Gallery Access

The App may request camera and image-library permissions to provide its scanning features.

The camera is used to:

• Scan printed or handwritten numbers

• Scan receipts

• Capture images for number or receipt recognition

• Provide optional flash functionality

Gallery access is used only when you choose an image to import. The App does not access unrelated gallery images.

3. Number and Receipt Recognition

The App uses Google ML Kit for initial on-device text recognition.

When local recognition is empty, unclear, or unreliable, the App may send the original or processed image to a configured cloud OCR or artificial-intelligence provider. Depending on service availability, these providers may include:

• Google Gemini

• Groq

• OpenRouter

• Other configured OCR or AI fallback providers

These services process submitted images or recognized text to return visible numbers or receipt information. Cloud processing is used to improve recognition of handwritten numbers, multilingual digits, and difficult receipt images.

Submitted images may contain information visible in the selected document. Do not scan documents containing information you do not want processed by these providers.

The handling of submitted information is also governed by the privacy policies and terms of the applicable service provider.

4. Voice Total and Microphone Access

Voice Total requires microphone permission and uses the speech-recognition service available through your device or operating system.

Speech audio may be transmitted to and processed by your device’s speech-recognition provider. The App receives the recognized text, extracts spoken numbers, and displays them for review and calculation.

The App does not intentionally save microphone recordings.

5. Expense Information

Expense records, income records, categories, budgets, and transaction history are primarily stored locally on your device.

Receipt images selected for expense records may remain stored locally so that you can view them later. Receipt images may also be submitted to a configured OCR or vision provider when cloud recognition is required.

The App does not intentionally upload your complete expense history to its own server.

6. Scan Allowances and Reinstall Recovery

The App offers limited free scans and may restore scan allowances after the App is reinstalled or its local data is cleared.

For this purpose, the App may process and store:

• A device-linked identifier

• Camera Calculator scan counts

• Receipt scan counts

• Allowance start dates or timestamps

This limited information may be stored locally, in supported device backup storage, and in Google Firebase Cloud Firestore.

The reinstall-recovery record does not intentionally contain:

• Scanned images

• Calculation history

• Expense or income records

• Your name

• Your email address

• Your phone number

Firebase may process information using Google’s global infrastructure. More information is available in Firebase Privacy and Security.

7. Advertising

Free users may see banner, native, interstitial, or rewarded advertisements supplied through Google AdMob.

Google and its advertising partners may process information such as:

• Advertising or device identifiers

• IP address

• Device and operating-system information

• Approximate location

• Ad interactions

• App interactions

• Diagnostic and fraud-prevention information

This information may be used to deliver ads, limit repeated ads, measure advertising performance, prevent invalid activity, and provide personalized or non-personalized advertising according to your location and consent choices.

Advertising information is processed according to Google’s Privacy Policy.

Where legally required, Google or the App may request consent before using information for personalized advertising. Available advertising choices may also be managed through your device or Google settings.

8. Purchases and Subscriptions

Premium subscriptions and purchase restoration are processed through Google Play.

The App may receive:

• Product and localized pricing information

• Purchase status

• Subscription entitlement status

• Information needed to restore an existing subscription

The App does not receive or store your complete payment-card information. Payment information is handled by Google Play according to Google’s Privacy Policy and Google Play terms.

Subscriptions renew according to the price and billing period displayed during the Google Play purchase process. You can manage or cancel a subscription through your Google Play account.

9. Files, Exports, and Sharing

When you choose to export calculation history or expense reports, the App may create PDF, CSV, spreadsheet, or image files on your device.

When you select Share, the App opens the device’s system sharing interface. You choose the application or recipient that receives the exported file.

Information shared through another application is governed by that application’s privacy practices.

10. Information We Do Not Intentionally Request

The App does not require users to create an account directly with us.

We do not intentionally request or maintain a user profile containing your:

• Name

• Personal email address

• Phone number

• Postal address

• Full payment-card details

Third-party services may still process device, network, purchase, advertising, image, or speech information as described in this policy.

11. Data Retention and Deletion

Calculation history, expenses, settings, and related information stored in normal app storage remain until you delete them, clear the App’s data, or uninstall the App, subject to device and platform backup behavior.

The limited device-linked scan-allowance record may remain after uninstallation because it is used to restore scan limits and prevent allowance abuse after reinstalling the App.

Cloud OCR and advertising providers may retain information according to their own policies and service terms.

For privacy questions or an applicable request concerning the device-linked allowance record, contact us at [YOUR SUPPORT EMAIL]. We may need additional information to identify the applicable record.

12. Data Security

We use platform storage mechanisms and encrypted HTTPS connections where supported. Third-party providers may also apply their own security controls.

However, no storage or transmission system can be guaranteed to be completely secure. Users should protect their devices with appropriate security settings.

13. Children’s Privacy

The App is not directed to children under 13, and we do not knowingly request personal information such as a child’s name, email address, or phone number.

If you believe a child has provided personal information through the App, contact us so that we can review the situation.

14. International Processing

Third-party providers may process information in countries other than the country where you live. Their data-protection laws may differ from those in your location.

For example, Firebase services may process information through Google infrastructure in multiple locations, as explained in Firebase Privacy and Security.

15. Changes to This Privacy Policy

We may update this Privacy Policy when the App’s features, service providers, data practices, or legal obligations change.

The “Last Updated” date at the beginning of this policy identifies the latest published version. We encourage users to review this page periodically.
