Last Updated: April 14, 2026

Operated by: FOREX LOT CALCULATOR SOFTWARE SERVICES (Udyam: UDYAM-KR-01-0058715)

Official Website: forexlotcalculator.in • Android Package: com.lotcalculator.app

1. Introduction

Welcome to Forex Lot Calculator. This Privacy Policy explains how FOREX LOT CALCULATOR SOFTWARE SERVICES (“we”, “us”, “our”) collects, uses, and safeguards your information when you use our mobile application (“the App”) and website (“the Site”).

We are committed to protecting your personal information and your right to privacy in accordance with applicable Indian data protection laws and international privacy standards.

This Site, the Google Play listing for the App, and the support contact information published on this domain are all operated by the same business entity and relate to the same software product.

2. Nature of Our Application

Forex Lot Calculator is a software application for lot sizing, risk review, and optional MT5 workflow support. It performs position-size (lot size) calculations based on user-provided numerical inputs and may, if enabled by the user, exchange data with the user’s own MT5 environment. This application is NOT an investment advisor, signal provider, recommendation service, broker, custodian, or fund manager. See our About Us page for full details.

3. Data We Collect

We collect the minimum data necessary for the functionality and improvement of the App:

3.1 Account Information

  • Google Account Data: When you sign in via Google, we receive your name, email address, and profile photo URL from Google. This is used for account identification and subscription management only.
  • User ID: A unique identifier assigned by our authentication provider (Supabase) for managing your account and subscription status.

3.2 Device Information

  • Device Model & OS Version: Collected for app compatibility and crash reporting.
  • Device Identifier: A hashed hardware-based identifier used solely to prevent abuse of free trial offers. This identifier is anonymized and cannot be used to identify you personally.

3.3 Usage Data

  • Anonymous Analytics: We collect anonymous usage statistics (screens visited, feature usage frequency) to improve app performance and user experience.
  • Crash Reports: Automatic crash reports to help us fix bugs and improve stability.

3.4 Calculation Inputs

IMPORTANT: Core calculator parameters are processed on your device. If you enable optional MT5 connectivity, selected symbols, prices, and user-selected values may be transmitted between your devices and your own MT5 environment to support those features. We do NOT operate a brokerage, manage funds, or store payment-card or broker-custody data.

3.5 Payment Information

  • Google Play Billing: Subscription purchases are processed entirely through Google Play. We do not collect or store your credit card, bank account, or payment card details. Google Play handles all payment processing.
  • Purchase Tokens: We receive purchase verification tokens from Google Play to confirm subscription status. These do not contain your financial information.

4. Third-Party Services

Our application uses the following third-party services, each with their own privacy policies:

  • Google Play Services: App distribution, in-app billing, and app updates. Google Privacy Policy
  • Google AdMob: Displays advertisements in the free version of the app. AdMob may collect device identifiers and usage data for ad personalization. Google Ads Privacy
  • Google Analytics / Firebase Analytics: Anonymous usage analytics and crash reporting to improve app quality. Firebase Privacy
  • Firebase Cloud Messaging: Sends push notifications (e.g., app updates, educational tips). You can disable notifications in your device settings.
  • Supabase: Authentication and subscription management backend. Supabase Privacy Policy
  • Meta (Facebook) Audience Network: Ad mediation partner for serving advertisements. Meta Privacy Policy
  • Google User Messaging Platform (UMP): Manages GDPR/privacy consent for users in the European Economic Area (EEA), UK, and Switzerland.
  • User’s Own MT5 Environment: If optional connectivity is enabled, the app may exchange trade-related parameters and market data with the user’s own MT5 installation or bridge setup.
