PRIVACY POLICY — QRWORKS
Last updated: March 22, 2026
================================================================================

1. OVERVIEW
--------------------------------------------------------------------------------
QRWorks ("the app") is developed by BackendSide ("we", "us", "our"). This
privacy policy explains what data the app accesses, how it is used, and what
is stored. The short version: QRWorks works entirely offline and collects no
personal data.


2. DATA WE DO NOT COLLECT
--------------------------------------------------------------------------------
We do not collect, transmit, sell, or share any personal information.
Specifically:

  - No account or registration is required
  - No analytics or crash reporting is sent to any server
  - No advertising SDKs or tracking libraries are included
  - No usage data, device identifiers, or behavioural data leaves your device


3. CAMERA
--------------------------------------------------------------------------------
The app requests camera permission solely to scan QR codes and barcodes in
real time. The camera feed is processed on-device using Google ML Kit. No
images or video are captured, stored, or transmitted. Camera access is only
active while the Scan screen is open and the app is in the foreground.


4. PHOTO LIBRARY / STORAGE
--------------------------------------------------------------------------------
When you generate a QR code and tap Save, the image is written to your
device's Photos gallery (Pictures/QRWorks/). This is a write-only action —
the app does not read or browse your existing photos. On Android 9 and below,
the app requests the WRITE_EXTERNAL_STORAGE permission for this purpose only.
On Android 10 and above, no storage permission is required.

When you use Scan from Image, the app requests read access to open a single
image you explicitly select. The selected image is not stored or copied by
the app.


5. SCAN AND GENERATION HISTORY
--------------------------------------------------------------------------------
All QR codes you scan or generate are stored in a local database on your
device (Room / SQLite). This data never leaves your device. You can delete
individual records or clear all history at any time from the History tab or
Settings.


6. PDF EXPORT
--------------------------------------------------------------------------------
When you export a PDF, the file is written to your device's local cache
directory and opened in a PDF viewer app of your choice. The file is not
uploaded anywhere.


7. THIRD-PARTY LIBRARIES
--------------------------------------------------------------------------------
QRWorks uses the following open-source libraries, all of which operate
entirely on-device:

  Library                        Purpose
  ------------------------------ -----------------------------------------------
  Google ML Kit Barcode Scanning Decoding QR codes and barcodes from the camera
  ZXing                          Generating QR code images
  CameraX                        Camera preview and frame capture
  Room                           Local on-device history database
  Jetpack Compose                UI framework
  Coil                           Image loading
  DataStore                      Storing app settings locally

None of these libraries send data to external servers when used within
QRWorks.


8. INTERNET ACCESS
--------------------------------------------------------------------------------
QRWorks does not require an internet connection for any of its core features.
The INTERNET permission is declared in the app solely to allow Android to open
URLs in the browser when you tap "Open in Browser" after scanning a link.
This is a standard Android intent that hands off to your browser app and
involves no network activity by QRWorks itself.


9. CHILDREN'S PRIVACY
--------------------------------------------------------------------------------
QRWorks does not knowingly collect any information from anyone, including
children under the age of 13. Because no data is collected at all, the app
is safe for use by all ages.


10. CHANGES TO THIS POLICY
--------------------------------------------------------------------------------
If we make changes to this privacy policy, we will update the "Last updated"
date at the top and publish the revised policy at the same URL. Continued use
of the app after any changes constitutes acceptance of the updated policy.
