Privacy policy

When contacting support, please include the app version, iOS version, device model, barcode type if known, and a short description of the issue. Do not send sensitive barcode data unless you have permission to share it.

2. What the App Does

Core purpose: GS1Barcode helps professional users scan, parse, inspect, and verify GS1 / UDI barcode data locally on the device.

3. Typical Workflow

  1. Scan a GS1 / UDI barcode with the camera, or import a user-selected barcode image.
  2. Review parsed GS1 fields and check whether key data elements are present.
  3. Use the debug view to inspect FNC1, GS, Hex, ASCII, and raw payload details.
  4. Continue scanning in batch mode when working through warehouse, inventory, quality, or field verification tasks.
  5. Export scan records as text, CSV, or JSON when you need to share or archive results.

4. Permissions

Camera: used for local real-time barcode scanning. The app does not upload camera frames or scan data.

Photos: barcode image import uses Apple PHPicker and only processes the image you choose. The app does not request full photo library access.

Clipboard and sharing: used only when you choose to copy, export, or share barcode data through iOS system features.

5. FAQ

Is GS1Barcode an official GS1 app?

No. GS1Barcode is an independent local scanning, parsing, and field verification tool. It is not an official GS1 app and does not provide GS1 certification.

Does the app certify UDI compliance?

No. The app can help review common UDI data elements and inspect barcode payloads, but it does not provide legal, regulatory, or medical compliance certification.

Does the app upload barcode data?

No. In the current release, scanning, parsing, history, and export are local-first. Data leaves the app only when you explicitly copy, export, save, or share it.

Why does the app need camera access?

Camera access is used to scan barcodes in real time. If you do not grant camera access, camera scanning will not work, but other local functions may still be available.

What barcode data can the app parse?

The app focuses on GS1 / UDI barcode payloads and GS1 Application Identifier field parsing. Support depends on the barcode content, symbol quality, and whether the payload follows expected GS1 semantics.

How should I report a parsing issue?

Email support with the app version, iOS version, barcode type, a description of the expected field result, and a sanitized sample if you are allowed to share it.
