1. Introduction

Welcome to Smart Calculator Toolkit ("the App"), developed and published by Low Cost EMI ("we", "us", or "our"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our Android application available on the Google Play Store.

By downloading or using the App, you agree to the terms described in this Privacy Policy. If you do not agree, please do not install or use the App.

 

2. Information We Collect

2.1 Information You Provide

The App is primarily a utility calculator application. We do not require you to create an account or submit personal information. However, the following data may be processed locally on your device:

•        Numbers and values entered into calculators (unit, currency, BMI, loan, tip, etc.)

•        Images or photos captured via camera for the AI formula scanner feature (processed locally or via AI API)

•        Preferences and settings you configure within the App

 

2.2 Information Collected Automatically

When you use the App, certain technical data may be collected automatically, including:

•        Device information (model, OS version, screen resolution)

•        App usage data (features accessed, frequency of use)

•        Crash logs and diagnostic data (via Google Firebase Crashlytics, if integrated)

•        Anonymized analytics data (via Google Analytics for Firebase, if integrated)

 

2.3 Camera Permission

The App requests access to your device camera solely for the AI Calculator feature, which allows you to scan and recognize mathematical formulas. Camera access is used only when you explicitly activate this feature. We do not store, transmit, or share any images or photos captured by your camera without your knowledge.

 

3. How We Use Your Information

We use the information described above for the following purposes:

•        To provide and operate the calculator features of the App

•        To process scanned formulas using AI recognition (images processed for formula detection only)

•        To improve App functionality, fix bugs, and enhance user experience

•        To analyze usage patterns in an anonymized and aggregated manner

•        To comply with applicable laws and legal obligations

 

4. Third-Party Services

The App may integrate or rely on the following third-party services. Each has its own privacy policy governing data use:

Service	Purpose	Data Shared
Google Play Services	App distribution & updates	Device info, App ID
Google Firebase	Analytics & crash reporting	Anonymized usage data
Exchange Rate API	Live currency conversion	No personal data
AI Vision API (if used)	Formula scanning	Cropped formula image only
Google AdMob (if shown)	In-app advertisements	Ad ID, device info

 

5. Permissions We Request

The App requests only the permissions necessary for its features:

Permission	Reason
CAMERA	Required for AI Calculator to scan mathematical formulas from physical paper or screen
INTERNET	Required for live currency exchange rates and AI formula recognition API calls
READ_EXTERNAL_STORAGE (optional)	Allows selecting an existing image from gallery for formula scan

 

6. Data Storage & Security

All calculations and inputs entered in the App are processed locally on your device and are not transmitted to our servers. We do not maintain a database of your personal calculations.

For features requiring internet connectivity (currency rates, AI formula scanning), only the minimum required data is sent to third-party APIs. We use industry-standard security practices to protect any data in transit.

While we strive to protect your information, no method of electronic transmission or storage is 100% secure. We cannot guarantee absolute security.

 

7. Children's Privacy

The Smart Calculator Toolkit is suitable for general audiences including students. We do not knowingly collect personal information from children under the age of 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately and we will take steps to delete such information.

 

8. Data Retention

Since we do not store personal data on our servers, there is no retention period applicable to user calculation data. Anonymized analytics data retained by third-party services (e.g., Firebase) is governed by their respective retention policies.

 

9. Your Rights

Depending on your location, you may have certain rights regarding your data:

•        Right to know what data is collected about you

•        Right to request deletion of your personal data

•        Right to opt out of analytics data collection (via App settings or device settings)

•        Right to withdraw camera permission at any time via Android device settings

To exercise any of these rights, please contact us at the email address provided below.

 

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. When we update the policy, we will revise the Effective Date at the top of this document and publish the updated version on the Google Play Store listing.

We encourage you to review this Privacy Policy periodically. Continued use of the App after any changes constitutes your acceptance of the updated policy.
