Expense Analyzer (Local-Only)

The tool lets users import bank‑statement CSV files and perform expense analysis entirely within their browser, without any data being sent to external servers. After mapping relevant columns such as date, amount, and optional category or memo fields, the application generates visual summaries including monthly spending trends, category breakdowns, and overall totals. Users can preview a few rows before analysis, export cleaned CSV data, and (in a paid tier) produce PDF reports or save custom column mappings.

Designed for individuals who prioritize financial data sovereignty, the software operates offline after the initial page load and requires no accounts, logins, or internet connection to function. It supports a range of banks and financial services, allowing drag‑and‑drop or manual file selection, and provides a sample dataset for exploration.

The primary audience consists of privacy‑concerned consumers and anyone needing a simple, local budgeting assistant that avoids cloud storage, advertising, or data‑broker exposure. Its distinguishing feature is the strict “zero‑trust” architecture that keeps all processing on the user’s device.
