Privacy Policy

Effective date: February 4, 2026

Introduction

Steel Weight Calculator ("we", "our", "us", or "the Developer") is a utility app designed to help civil engineers, contractors, and individuals calculate the weight and cost of metal materials. This Privacy Policy explains how the app handles data and what choices you have. We respect your privacy and are committed to protecting it. The app is designed to function primarily offline, storing data locally on your device.

Information Collection & Storage

1. Local Data (On your device)

Steel Weight Calculator stores your preferences (such as selected units) and any saved calculation history locally on your device's internal memory. This data stays on your phone and is not transmitted to our servers.

2. Personal Information

We do not collect personally identifiable information (such as your name, email address, or phone number) directly through the app. You can use the app without creating an account.

3. Analytics & Advertising Data

The app uses third-party services (Google AdMob and Google Firebase) which may collect anonymous data to improve the app and display relevant advertisements. This may include:

  • Device Advertising ID (for ad personalization).
  • App crash reports and performance data (to fix bugs).
  • General device information (model, OS version).

How We Use Information

  • To perform accurate weight and cost calculations on your device.
  • To save your calculation history for your future reference (stored locally).
  • To display advertisements via Google AdMob (which helps keep the app free).
  • To analyze app stability and fix crashes using Google Firebase Crashlytics.
  • To respond to support requests sent to our contact email.

Advertising & Third-Party Services

This app displays ads provided by Google AdMob. These advertising networks may use cookies or unique device identifiers to show ads based on your interests or location.

We also use Google Firebase for analytics. You can learn more about how Google handles data by visiting their privacy policy: Google Privacy Policy.

Permissions

The app may request the following permissions:

  • Internet/Network Access: Required to load advertisements and send crash reports.
  • Storage (Optional): Required only if you choose to save or export calculation reports as PDF/Image files to your device storage.

Data Retention & Deletion

Since we do not store your personal data on our servers, we cannot delete it for you. Your saved calculations and preferences remain on your device until you clear the app data or uninstall the app.

Children's Privacy

The app is not specifically targeted at children under the age of 13. We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.

Security

We take reasonable measures to protect the integrity of the app. However, please remember that no method of electronic storage or internet transmission is 100% secure.

Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the "Effective date" at the top of this page. You are advised to review this page periodically for any changes.
