Privacy Policy

1. Privacy-First Design Philosophy

Expense Tracker is built with a fundamental commitment to privacy. Unlike most financial applications, we believe your financial data should remain completely under your control. This privacy policy explains how we protect your information and why our approach is different.

2. Data Collection and Storage

2.1 What We Don't Collect

We do not collect or store any of the following:

• Personal financial information (expenses, income, budgets)
• Email addresses, names, or personal identifiers
• Bank account details or payment information
• Location data or device identifiers
• Usage analytics or behavioral tracking

2.2 What We Store Locally

All your financial data is stored exclusively on your device using:

3. No Account Required

Expense Tracker eliminates the biggest privacy risk in financial applications: the account system. By removing the requirement for accounts, we:

• Eliminate the need to store personal identifiers
• Remove the risk of data breaches from centralized servers
• Ensure complete anonymity in your financial tracking
• Give you full control over your data lifecycle

4. Offline-First Architecture

4.1 Local Processing

All financial calculations, analytics, and data processing happen locally on your device. This includes:

• Budget calculations and spending summaries
• Category breakdowns and financial reports

• Maintain data ownership rights

5.2 Import Capabilities

Data import is entirely user-initiated and processed locally. We never have access to imported financial data.

6. Payment Processing

6.1 Third-Party Payment Processing

Premium upgrades are processed through Razorpay, a secure third-party payment processor. We:

• Do not store payment information on our servers

• Use secure tokenized payment processing
• Comply with PCI DSS standards through Razorpay

6.2 Minimal Transaction Data

The only payment-related data we might process is:

• Payment confirmation status (for premium activation)

• No personal or financial details are stored

7. Cookies and Tracking

7.1 No Tracking Cookies

Expense Tracker does not use:

• Analytics tracking cookies

• Behavioral profiling technologies

7.2 Essential Technical Storage

The only browser storage we use is for:

• Offline caching (service worker)

8. Security Measures

8.1 Client-Side Security

9. Third-Party Services

9.1 Limited Third-Party Integration

We minimize third-party services to:

• No social media integration

9.2 Service Provider Privacy

When using third-party services, we ensure:

• No personal financial data is shared
• Privacy policies are reviewed and compliant
• Data processing agreements are in place
• Minimum necessary data is shared

10. Data Retention and Deletion

10.1 User-Controlled Data Lifecycle

Since all data is stored locally, you have complete control over:

• When to delete individual transactions
• When to clear all application data
• When to export and delete data
• Application uninstallation (removes all data)

10.2 No Server-Side Retention

We do not retain any of your financial data on servers, ensuring complete privacy by design.

11. Children's Privacy

Expense Tracker does not knowingly collect personal information from children under 13. Since we don't collect personal information anyway, this is naturally enforced by our privacy-first architecture.

12. International Data Transfers

Since all data is stored locally on your device, there are no international data transfers. Your financial data remains within your jurisdiction and control.

13. Your Privacy Rights

13.1 Complete Data Control

With Expense Tracker, you have:

• Right to access all your data (it's already on your device)
• Right to modify any transaction or entry
• Right to delete any or all data instantly
• Right to export your data in standard formats
• Right to uninstall and remove all data

13.2 No Data Requests Needed

Unlike traditional services, you don't need to request data access or deletion - you already have complete control.

14. Changes to This Privacy Policy

We may update this privacy policy to reflect changes in our practices or for legal and regulatory reasons. Any changes will be posted on this page with an updated revision date. Significant changes will be highlighted in the application.

15. Contact Information
