Privacy Policy for Bill Eka

Last updated: October 26, 2026

Lanka Grocery Insights ("we", "our", or "us") operates the Bill Eka mobile application ("App"). This Privacy Policy explains how our App collects, uses, and safeguards your information when you use our mobile application.

1. Information We Collect

Camera & Photo Access: The App requests permission to access your device camera and image library solely to allow you to scan paper supermarket receipts and shelf price tags. Captured images are uploaded to our server and sent to Google's Gemini AI API for parsing (see Section 3).
Account & Authentication Information: If you sign in with Google, we receive your basic profile information (name, email address). If you sign in with your phone number, we collect that phone number and send a one-time verification code to it via our SMS provider (Text.lk).
Receipt & Purchase Data: Parsed receipt data — store name, items, quantities, prices, categories, and totals — along with the category budgets you set. Your shopping list and app preferences stay on your device and are not sent to our servers.
Usage Logs: For each receipt or shelf-tag scan we record when it happened, whether it succeeded, how long it took, and how much AI processing it used. We also record when your account was first and most recently active. These logs do not contain the contents of your receipts. We use them to keep the service reliable and to plan and price it fairly.
Account Transfer Codes: If you use Move data to another account, we create a one-time transfer code. We never store the readable code, only a scrambled (hashed) version linked to your account together with its expiry time. The code works once and stops working after 15 minutes. It is removed when it is used, when you ask for a new code, or when you delete your account. Entering a valid code moves the saved receipts of the account that issued it into the account that entered it.

2. How We Use Your Information

To process supermarket receipt and shelf-tag images and parse expense data (item names, quantities, and totals).
To generate smart shopping auto-fill suggestions based on your historical purchase frequency.
To compare supermarket prices (Keells, Cargills, Arpico, Spar, Glomark) and calculate cost projections.
To enforce user-defined budget alerts and spending breakdown analytics.
To authenticate you and keep your account secure (Google sign-in or phone number + one-time code).
To let you move your saved receipts from one of your accounts to another using a one-time transfer code.

3. Data Security & Storage

Your account and receipt data are stored on our servers in a secured database and transmitted between the App and our servers over encrypted HTTPS connections. We do not sell, rent, or trade your personal information or receipt data to any third-party advertisers.

To parse receipt and shelf-tag photos, we send the image to Google's Gemini API for AI-based text extraction; to deliver phone sign-in codes, we send your phone number to our SMS provider, Text.lk. These providers process this data on our behalf and do not use it for their own advertising purposes.

4. Permissions Requested

CAMERA: Required for capturing receipt and price tag photos in real-time.
READ_EXTERNAL_STORAGE / READ_MEDIA_IMAGES: Required for picking receipt images from your photo gallery.
INTERNET: Required for authenticating users and querying AI receipt layout parsing services.

5. Data Deletion & User Control

You can delete any single receipt from your receipt history to remove it and its items from our servers. To permanently delete your account and every receipt and budget stored on our servers (and clear the data saved on your device), open Profile in the App and tap Delete account & data under Your data. This takes effect immediately and cannot be undone. You can also request deletion from outside the App — see how to delete your account — or by contacting us using the details below.
