Floating Sage Business will be available on the Google Play Store. Search for “Floating Sage Business”, install, and follow the on-screen onboarding to create your business profile. The app does not require an internet account or sign-up form — setup is local to your device.

Floating Sage Business is built to keep going. All core features — billing, inventory, queue management, customer records, GST invoicing, and multi-device sync — continue uninterrupted. Only optional features (WhatsApp messaging, off-network sync relay, and app updates from the Play Store) use the internet.

One device is the “super-admin” (typically the owner’s device). Your other devices connect to it directly over your local network. Sales, invoices, queue updates and other events stream peer-to-peer between devices in near real-time, all over an encrypted connection. The data never leaves your local network during sync.

Yes, optionally. There’s an off-network relay feature that passes encrypted sync messages between your devices. The relay sees only opaque encrypted data and routing tokens — never your business data. The relay is opt-in and can be disabled at any time from More → Sync settings.

When multi-device sync is enabled, Android requires apps that maintain a background network service to run as a foreground service with a persistent notification. This is a privacy and battery-life protection from Android — you should always know when an app is doing background work.

Floating Sage Business uses the connectedDevice foreground service type. It is active only when sync is enabled, and the notification accurately reflects whether the relay is currently running. You can disable sync from More → Sync settings, which will also remove the notification.

The service does not access your location, microphone, camera, or contacts. It only listens for incoming connections from your other devices on your local network.

Open the app → More → Manage Data → Backup. The app produces an encrypted, tamper-evident backup file. You choose where to save it — share to Google Drive, send via WhatsApp, save to your SD card, or attach to email. The backup file is bound to a passphrase you set; only that passphrase can restore it.

On the device you want to restore to, install the app and tap Restore from backup on the welcome screen. Select the backup file, enter its passphrase, and confirm. The app verifies the file’s authenticity, then decrypts and imports the data. A backup file with even one byte modified will fail the integrity check and not import.

The admin PIN protects your business data on this device. If you have at least one other connected device or a recent backup file, you can reset the PIN by re-pairing or restoring from backup. If you have no backup and no second device, PIN recovery is not possible by design — the encryption key is derived from your PIN and held in your phone’s secure storage; without the right PIN there is no way to unlock it. This is a deliberate trade-off for on-device security.

We strongly recommend creating a backup file at the end of every working day and saving it somewhere outside the device.

Yes, optionally. Floating Sage Business integrates with the WhatsApp Business API. You enter your own API token from Meta, and the app sends invoices on your behalf. The token is kept in your phone’s secure hardware-backed storage, never in the database, and is never replicated across your synced devices. The feature is fully opt-in.

The app runs on any modern Android device. The interface adapts to the screen you’re using — quick-action flows on smaller screens, fuller billing flows on larger ones — and every device on your business’s sync sees the same data.

Floating Sage Business supports Android 8.0 (Oreo, API 26) and above. We test regularly on Android 12, 13, 14, and 15.

No. The app does not phone home with usage data of any kind, and we never see what you’re doing inside it. Crash reports and bug reports are user-initiated only — you choose what to share, and only by email.

No. Your data lives on your device, in your hands — never sold, never shared. See the privacy policy for the full picture, including the narrow set of exceptions for opt-in features you can choose to enable.
