Last updated: May 14, 2026
Introduction
Welcome to TradeCalc USA. This Privacy Policy explains how the TradeCalc USA Android application (“App,” “we,” “our,” or “us”) handles information when you use the app.
TradeCalc USA is an offline-first construction and contractor utility application designed for estimations, calculations, invoicing, and project management tasks related to roofing, concrete, paint, tile, drywall, and similar trades.
We are committed to protecting user privacy and being transparent about how the app operates.

No Personal Information Collected
TradeCalc USA does not collect, transmit, store, or share personal information such as:
- Name
- Email address
- Phone number
- Physical address
- GPS location

The app does not require user account creation or sign-in.
Project and Calculation Data
Any project information entered into the app, including:

is stored locally on the user's device only.

Offline-First Data Storage
TradeCalc USA is built using an offline-first architecture.
All application data is stored locally on your Android device using:
- Encrypted local databases (Room Database)
- Android Preferences DataStore
This means:
- Your calculation data stays on your device
- Your project records stay on your device
- Your notes and invoices stay on your device
- No cloud synchronization occurs
- No remote backup is performed by the app
Users maintain full control over their locally stored data.
If you uninstall the app, locally stored data may be deleted unless separately backed up by the user or the Android operating system.
Internet Access and Permissions
The app may request limited internet access solely for required Google Play functionality, including:
- In-App Reviews
- In-App Updates
- Google Play integrity and delivery services
The app does not use internet access to collect or transmit user project data.
Notifications Permission
TradeCalc USA may request notification permission in order to:
- Display important app-related notifications
- Inform users about updates or reminders
Notification data is not shared externally.
Third-Party Services
TradeCalc USA uses limited Google Play Services components provided by Google.
These services may process technical device information as necessary for their operation.
Google Play Services Used
- Google Play In-App Review API
- Google Play In-App Update API
These services are governed by Google’s own privacy policies:
TradeCalc USA does not control how Google processes information through these APIs.
Data Sharing

- Sell user data
- Rent user data
- Share personal information with advertisers
- Upload contractor project data to external servers
- Share stored calculations or invoices with third parties
The only limited data interactions may occur through Google Play Services strictly for app platform functionality.
Data Security
We use reasonable technical measures to help protect locally stored application data, including encrypted local storage mechanisms where applicable.
However, no device or software environment can be guaranteed to be completely secure. Users are responsible for maintaining the security of their own devices.
User Rights and Controls

- Users retain direct control over their data
- Users may delete app data at any time through Android settings
- Users may uninstall the app to remove stored local data
- No account deletion request is necessary
