Last updated: February 26, 2026

At Mona Cash, we take your privacy seriously. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our personal finance management platform.

1. Information We Collect

When you create an account, we collect:

  • Email address
  • Authentication provider information (Google, GitHub, X)
  • Account creation date

1.2 Financial Data

When you use our service, you may provide:

  • Account names and balances
  • Transaction records (amounts, dates, descriptions)
  • Budget configurations
  • Wishlist items and savings goals

1.3 Usage Data

We automatically collect certain information about your device and usage of the Service, including IP address, browser type, pages visited, and time spent on the platform. This data helps us improve the Service.

2. How We Use Your Information

We use the information we collect to:

  • Generate financial reports and insights
  • Improve and personalize user experience
  • Communicate with you about service updates
  • Prevent fraud and ensure security

3. Data Storage and Security

3.1 Data Storage

Your data is stored securely using Supabase (PostgreSQL), which provides industry-standard encryption at rest and in transit. We implement Row Level Security (RLS) to ensure your data is only accessible by you.

3.2 Security Measures

We employ appropriate technical and organizational measures to protect your data, including encryption, secure authentication, and regular security assessments. However, no method of transmission over the Internet is 100% secure.

4. AI and Data Processing

For Pro users who opt into AI-powered features (such as intelligent bill import), transaction descriptions may be sent to third-party AI services for categorization. We never send complete financial details (amounts, dates, account balances) to AI services. You can choose to use local rule-based categorization instead at any time.

5. Data Sharing and Disclosure

We do not sell, trade, or otherwise transfer your personal information to third parties except in the following circumstances:
