CestApp

Privacy Policy

Last updated: April 1, 2026

Overview

CestApp ("the App") is developed by JBGSoft. This privacy policy explains how we handle information when you use our receipt scanning application.

The short version: CestApp does not collect, store, or transmit any personal data to external servers. All OCR processing happens on-device using Google ML Kit, and all data stays on your phone.

Information We Collect

We do not collect any information.

CestApp is designed with privacy as a core principle:

  • No personal information is collected
  • No receipt images or data are uploaded
  • No usage analytics or tracking
  • No crash reporting to external services
  • No advertising or ad tracking
  • No account creation required
  • No network requests are made

On-Device OCR Processing

CestApp uses Google ML Kit for text recognition (OCR). This processing happens entirely on your device:

  • ML Kit's Latin text recognition model is bundled with the app
  • Receipt images are processed locally and never leave your phone
  • No image data is sent to Google or any third party
  • Processed images are discarded after text extraction

Data Stored on Your Device

CestApp stores the following data locally on your device only:

1. Receipt Data

  • Store name and date
  • Item names, quantities, and prices
  • Item categories (auto-assigned and user-corrected)
  • Receipt totals

2. User Preferences

  • Category customizations
  • Learned item-to-category mappings
  • Display preferences

This data is stored using SQLite (via Drizzle ORM) on your device and never leaves your phone. You can clear this data at any time through your device's app settings.

Data Sharing

We do not share any data with third parties because we do not collect any data.

Permissions

CestApp requests the following permissions:

Permission Purpose
Camera To capture receipt photos using the document scanner
Photo Library To select receipt images from your gallery

These permissions are only used for receipt capture. No images are uploaded or shared.

Children's Privacy

CestApp does not collect personal information from anyone, including children under 13. The app is safe for all ages.

Data Security

Since no data is collected or transmitted, there is no risk of data breach from our servers. All locally stored data uses standard device storage mechanisms and is protected by your device's security features.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected in the "Last updated" date above. Continued use of the app after changes constitutes acceptance of the updated policy.
