1. INTRODUCTION
Welcome to Vbill ("we", "our", or "us"). We respect your privacy and are committed to protecting your personal and business data. This Privacy Policy explains how your information is handled when you use the Vbill Android mobile application (the "App").
Vbill is designed as an offline-first utility built specifically for contractors, carpenters, interior designers, fabricators, and site supervisors to calculate labour bills, maintain measurement sheets, track payments, and generate professional PDF invoices.
2. OFFLINE-FIRST ARCHITECTURE & DATA OWNERSHIP
Vbill operates on an offline-first architecture:
- 100% Offline by Default (Guest Mode): You can create clients, calculate room measurements, generate bills, and export PDF invoices entirely offline without registration or login.
- Data Ownership: Your invoices, measurements, client records, and financial figures belong solely to you. We never sell, rent, monetize, or share your personal or business records with advertisers or third-party brokers.
- No Unwanted Tracking: We do not track your GPS location, browsing habits, or personal communications.
3. ACCOUNT INFORMATION & GOOGLE CLOUD BACKUP (VBILL PRO)
When you optionally choose to sign in with your Google Account:
- Authentication Data: We receive your Google email address, display name, and avatar picture provided by Google Identity Services / Android Credential Manager to authenticate and associate your backup data with your account.
- Encrypted Cloud Synchronization: For Vbill Pro users who enable Google Cloud Sync, your local business profile, clients, sites, bills, and payment records are synchronized to Google Cloud Firestore via secure encrypted protocols (TLS/HTTPS).
- Sign Out & Disconnect: You can disconnect your Google Account or disable auto-sync at any time in the Settings screen.
4. GOOGLE PLAY SUBSCRIPTIONS & BILLING
- Subscription Management: Vbill Pro offers monthly and annual auto-renewing subscriptions to unlock unlimited clients, unlimited bills, white-label PDFs, and continuous cloud backup.
- Payment Processing: All payments and subscriptions are processed exclusively and securely through Google Play Billing.
- Zero Financial Data Stored: We do not collect, store, or have access to your credit card numbers, debit cards, UPI credentials, or bank account information. All transactions are governed by the Google Play Terms of Service.
5. INFORMATION STORED LOCALLY ON YOUR DEVICE
All data you enter into the App is stored securely within your device's private SQLite database (Android private sandbox storage):
- Client Information: Client names, contact phone numbers, and site addresses.
- Measurement & Bill Details: Room names, item descriptions, dimensions, unit types, rates, discounts, GST %, and totals.
- Payment Ledger: Advance payments received, payment modes, transaction dates, and reference notes.
- Business Profile: Business name, contractor title, contact number, business address, GSTIN, and custom invoice terms.
6. DEVICE PERMISSIONS USED
The App requests only the essential Android permissions required for core features:
- Internet & Network Access: Required only for optional Google Cloud backup synchronization and Google Play subscription validation.
- Storage / File Access: Used strictly to export, save, view, and print generated PDF invoices on your device storage.
- Android Share Sheet: Used only when you explicitly choose to share an invoice, PDF document, or payment statement via WhatsApp, Email, or other communication apps installed on your device.
7. ACCOUNT & DATA DELETION POLICY
In compliance with Google Play Developer Policies, users have full rights to delete their data at any time:
- In-App Data Management: You can delete any individual client, site, invoice, or payment record at any time inside the app.
- Local Data Erasure: You can erase all local data immediately by clearing app storage under Android Settings > Apps > Vbill > Storage > Clear Data, or by uninstalling the application.
- Cloud Account & Data Deletion: To permanently delete your Google account association and wipe all synchronized cloud backups from our servers, visit our dedicated deletion page:

Alternatively, you may email support.vbill@gmail.com with the subject "Account Deletion Request", and your data will be permanently purged within 7 business days.
8. THIRD-PARTY SERVICES
Vbill does not serve third-party advertisements. The app uses standard, industry-trusted Google services:
- Google Play Services / Android Credential Manager: For secure Google One-Tap authentication.
- Firebase Cloud Firestore: For encrypted cloud backup storage.
- Google Play In-App Billing: For subscription purchases.
9. CHILDREN'S PRIVACY
Vbill is a business utility intended for contractors and trade professionals. We do not knowingly collect information from children under 13 years of age.
