🧾 Bill Snap – Privacy Policy

Last Updated: May 2026

Welcome to Bill Snap. Your privacy is important to us. This Privacy Policy explains how your information is collected, used, stored, and protected when using the Bill Snap Android application.

📌 About Bill Snap

Bill Snap is an offline-first expense tracker and bill scanning Android application that helps users:

📸 Scan receipts and bills using the device camera (with optional AI extraction)
✍️ Manually add expenses and transactions
💰 Track expenses with 19+ built-in categories plus custom categories
📊 View analytics, monthly trends, and category breakdowns
🎯 Set monthly category budgets with overspend alerts
📦 Backup, restore, and export data as PDF or Excel

📂 Information We Collect

Bill Snap is designed so that your personal financial data stays on your device. We do not operate a server, and we do not collect, transmit, or sell your bills, receipts, or analytics to anyone.

📷 Bill Images

When you scan or upload a bill, the app may process:

The bill image (stored locally on your device)
OCR text extracted on-device
Extracted bill information (shop name, items, prices, totals, date)

🧾 Expense Information (stored locally)

Shop names, addresses, dates
Items, quantities, prices, discounts
Categories (built-in or custom)
Payment methods (cash / card / online)
Bill totals and final amounts
Monthly category budgets

⚙️ App Settings (stored locally)

Selected currency
Theme preference (light / dark / system)
Custom categories you create
Anthropic API key (if you choose to use AI extraction)
Onboarding and tutorial completion flags

🤖 AI Processing (Optional)

AI bill extraction is optional. If — and only if — you provide your own Anthropic API key, the app will send the bill image to Anthropic’s Claude API to extract structured data (shop name, items, totals, etc.).

AI provider used: Anthropic Claude
What is sent: the bill image and a system prompt asking the model to return structured JSON
What is NOT sent: your other bills, history, analytics, or any personal account information
When AI is disabled or unavailable: the app falls back to an on-device rule-based parser. No data leaves your device in this case.

If you do not enter an API key, AI extraction is fully disabled and the app operates in 100% offline mode for scanning.

Anthropic’s privacy practices apply to data sent to their API: 👉 https://www.anthropic.com/legal/privacy

🔐 API Keys

Your AI API key:

Is stored locally on your device
Is never transmitted to us or any third party other than Anthropic when you initiate an AI extraction
Can be removed at any time from the AI Setting screen

💾 Data Storage

Bill Snap stores all your data locally on your device.

We do not operate any cloud server. We do not synchronise your data across devices. We do not maintain user accounts.

📦 Backup & Restore

The app allows you to:

Create a local backup file containing all bills, categories, and budgets
Restore data from a backup file
Transfer data between your own devices using a backup file

You are solely responsible for the security of any backup file you create, share, or move outside the app.

📤 Export Reports

You may export your bill history as PDF or Excel (.xlsx) files for your own records. These files are saved to your device’s Downloads folder. The app does not transmit exported files to any server.

📱 Permissions Used

Permission	Purpose
📷 Camera	Required to scan bills with the camera
🖼️ Photo Library / Media Images	Required to select existing bill images from your gallery
📁 Storage / Downloads	Required to save backups and PDF/Excel exports to Downloads
🌐 Internet	Required only for AI extraction (if enabled)

The app requests permissions only when needed and explains the reason.

🔒 Security

We take reasonable measures to protect your data while it is on your device. However, no method of electronic storage is completely secure. We cannot guarantee absolute security.

You can enhance your privacy by:

Using device-level encryption (default on modern Android)
Setting a screen lock
Storing backup files in a secure location

🔄 Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes to our app or to applicable laws. The “Last Updated” date at the top of this document indicates when the policy was last revised. Continued use of the app after changes are posted constitutes acceptance of the updated policy.
