Bille: Billing & POS — Privacy Policy

Effective date: 1 November 2026

Summary

Bille works offline. Your business data (items, bills, customers, expenses, shop details and logo) is stored only on your device. Bille has no account, no login and no Zetran server. We do not sell your data.

Data stored on your device

Items, stock, purchase and sales bills, customers, expenses, business profile and images you add (logo, item photos). This data never leaves your device through the app. Uninstalling the app removes it.

Data collected automatically

Bille uses Google Firebase as a service provider for:

  • Firebase Analytics: app usage events and screen views, to understand which features are used.
  • Firebase Crashlytics: crash reports and diagnostics (stack traces, device model, Android version, app version) to fix bugs.

These services also use a Firebase installation ID and may derive an approximate location (country/region) from the IP address. They do not receive your business data, customer details, bill contents, photos or any personal information you enter. Bille does not use the advertising ID and shows no ads. Data is sent to Google over HTTPS. See Google's privacy policy at https://policies.google.com/privacy.

Permissions

  • Camera: to scan barcodes and take item or logo photos.
  • Photos / media picker: to choose a logo or item image.
  • Bluetooth: to print receipts on a thermal printer you have already paired; requested only when you print. Bille does not scan for or track location.
  • Notifications: for reminders you enable.
  • Internet: only for Firebase Analytics and Crashlytics.

Backup

If Android Auto Backup / device transfer is on, Android may copy the app's local database and logo images to your own Google backup so they can be restored on a new device. This is controlled by your device settings, and you can turn it off there. Zetran cannot access that backup.

Sharing

We do not share your data with third parties, other than Google/Firebase acting as our service provider as described above.

Retention and deletion

Local data stays on your device until you delete it or uninstall the app. Analytics and crash data is kept by Firebase under Google's standard retention. Bille has no accounts, so there is no account to delete. To ask about analytics data, contact us at bille.support@zetran.com.

Children

Bille is for adults running small businesses and is not directed to children.

Changes

We will post any changes on this page and update the effective date.
