JB One is an operations app for gold and silver jewellery retailers, used by shop staff to print jewellery tags and prepare customer estimates. It also has a web catalogue that each shop can publish, described in section 10. This policy explains what information JB One handles, why, and the choices available to you. JB One is set up by a jewellery shop's owner for their own staff.

Information we collect

We do not collect precise or coarse location, contacts, microphone audio, call logs, or SMS content, and the app does not read your camera or photos in the background.

How permissions are used

PermissionWhy the app asks for it
BluetoothTo find and print to the shop's thermal label or receipt printer over Bluetooth.
LocationRequired by Android itself before any app can scan for nearby Bluetooth devices, on phone software older than Android 12. JB One does not read, store, or transmit your location.
Storage / filesTo import a spreadsheet of items for bulk tag printing, to choose a logo image for a label, and to save exported PDFs on older Android versions.
InternetTo fetch the day's gold/silver market rate, sync the shop's shared configuration, and, for the administrator only, sign in to Google Drive.

The app does not ask for the camera or microphone permission. If staff choose to take a photo for a product in Shop Login, Android opens its own camera or photo picker for that one photo.

How we use information

Solely to operate the features described above: printing tags and receipts, calculating estimates, keeping shop-wide settings in sync across devices, and showing the day's metal rate. We do not use any information for advertising, and we do not build profiles of individual users.

Third-party services

JB One does not contain advertising or analytics SDKs, and we do not sell or rent information to third parties. The only Google services it uses are the ones listed above.

Data storage & retention

Business data entered on a device (item lists, estimates, saved label designs) is stored locally on that device and used to drive printing. Your login session is stored locally on the device and is removed automatically when the app is uninstalled. The shared shop configuration lives in the administrator's own Google Drive for as long as the shop chooses to keep it there.

Data sharing

We do not share information with third parties for their own marketing or advertising purposes. Information leaves a device only when a staff member deliberately connects to a printer and sends a print job, deliberately shares a receipt (for example, over WhatsApp or as a PDF), when staff upload a product photo to the shop's catalogue website, or when the administrator saves shop configuration to their own Google Drive.

Children's privacy

JB One is a business tool for retail staff and is not directed at, marketed to, or knowingly used by children. We do not knowingly collect information from anyone under 13 (or the relevant minimum age where you live).

Your choices

Because JB One is deployed by a shop for its own staff, requests about a staff account (adding, changing, or removing one) are usually handled directly by that shop's administrator. To ask about data related to your own use of the app, or to request that information be corrected or deleted, contact us using the details below.

Data kept on your device (saved label designs, item lists, your login session) can be removed at any time by clearing the app's storage or uninstalling the app.

Requesting data deletion

Email us at the address below with the subject line "Data Deletion Request", and include the shop name and your username or registered mobile number. This covers staff accounts and, for the online catalogue, customer accounts and enquiries. We will confirm and process the request. Some records, such as orders, may need to be kept where the shop has a legal or accounting duty to keep them.

Security

We use encrypted network connections and a signed application package to protect information handled by the app. No method of storage or transmission is completely secure, and we cannot guarantee absolute security.

JB One Web (the online catalogue)

Each shop can publish an online catalogue on its own web address, with an admin back office for the shop's staff. This section covers that web catalogue.

Changes to this policy

We may update this policy as the app changes. Material changes will be reflected by updating the "Last updated" date at the top of this page.
