Information We Collect
02When you use Budget King, we collect the following categories of data to enable core app functionality. All financial data is entered by you — we never access your bank accounts or payment systems.

03We use the information we collect for the following purposes and nothing beyond:
- Authenticate your identity via Google Sign-In and maintain your session securely

- Enable you to manage shops, categories, and recurring transactions
- Send you budget alerts and notifications you configure within the app
- Improve app performance, fix bugs, and develop new features based on usage patterns
- Ensure the security and integrity of your account and our services
Data Storage
04Your data is securely stored using Supabase, an open-source cloud database platform built on PostgreSQL. Supabase servers are hosted on AWS infrastructure, which comply with industry-leading security and compliance standards including SOC 2 and GDPR.

Data Sharing
05We take your privacy seriously. We do not sell, trade, or rent your personal information to any third party. Your data may be shared only in these limited circumstances:
- Supabase — as our infrastructure provider for database storage and authentication
- Legal obligations — if required by law, court order, or government authority
- Safety & security — to protect the rights, property, or safety of Budget King, its users, or the public
Data Security
06We implement robust technical and organisational measures to protect your information against unauthorised access, loss, destruction, or alteration.
- Authentication is handled exclusively via Google Sign-In OAuth 2.0 — we never store your Google password
- Supabase Row-Level Security (RLS) ensures each user can only access their own data
- All communications between the app and Supabase are encrypted via HTTPS/TLS
- We regularly review and update our security practices to stay ahead of emerging threats
- App access is tied to your Google account — enabling Google's two-factor authentication provides an additional layer of protection
