Privacy Policy for Slip Tracker ZA
Published by ReederDevelopments • Package: com.reederdevelopments.sliptrackerza
1 Introduction
ReederDevelopments respects your privacy. We engineered Slip Tracker ZA (com.reederdevelopments.sliptrackerza) with a strict 100% local-first, privacy-first architecture. This Privacy Policy explains how your shopping slips, receipt images, monthly budgets, and device permissions are handled when using the Slip Tracker ZA mobile application.
2 Local-First Data Storage (Zero Cloud Policy)
Slip Tracker ZA operates without central cloud servers, mandatory user accounts, or remote databases storing your personal shopping history or financial records.
-
On-Device SQLite & File Storage: All scanned shopping slips, extracted line items, store profiles, monthly Rand (
R) budgets, and cropped receipt photos are stored exclusively on your local Android device inside the application's private sandboxed storage. -
No Developer Access to Your Slips: ReederDevelopments cannot view, access, collect, transmit, or sell your shopping receipts, purchasing habits, store preferences, or budget data.
3 On-Device OCR Scanning & Encrypted Backups
All receipt image processing and backup archival operations occur locally on your phone:
-
On-Device Optical Character Recognition (OCR): When you photograph or select a shopping slip from your gallery, image cropping and text recognition (via Google ML Kit Text Recognition) run 100% locally on your device processor. Your receipt photos are never uploaded to external cloud OCR servers.
-
AES-256 Encrypted Local Backups (
.sliptracker): Slip Tracker ZA allows you to export all your stores, slips, budgets, and embedded Base64 receipt images into a portable.sliptrackerbackup file. When you supply a backup password, the backup payload is encrypted on-device using AES-256-CBC with SHA-256 key derivation before being saved to your device.
4 Third-Party Services
Slip Tracker ZA integrates with the following third-party SDKs to support core functionality and app distribution:
-
Google AdMob (Google Mobile Ads SDK): Serves banner advertisements within the app. Google AdMob may collect device identifiers (such as your Android Advertising ID), coarse location/IP metadata, and ad interaction metrics to serve and measure advertisements. Please review How Google uses information from sites or apps that use our services.
-
Google ML Kit Text Recognition: Performs on-device text extraction from shopping receipts. Image frames are processed locally on your device without transmitting receipt images to external servers.
5 Permissions Requested
Slip Tracker ZA requests only the minimum Android permissions needed to function:
| Permission | Purpose |
|---|---|
Camera (android.permission.CAMERA)
|
Used to photograph shopping slips and custom store logos for on-device OCR scanning and cropping. |
Internet (android.permission.INTERNET)
|
Used to load Google AdMob banner ads and Google Fonts when online. The core slip scanner and budget tracker work offline. |
6 Data Control, Retention & Deletion
You retain 100% ownership and control of your data. Because all records reside locally on your physical device, you can delete individual slips or permanently wipe all stored application data at any time by:
- Deleting individual slips, stores, or backups directly inside the Slip Tracker ZA interface;
- Clearing storage/app data via your Android System Settings; or
- Uninstalling the Slip Tracker ZA application from your device.
