Ocular

The application provides a self‑hosted budgeting tool that lets users track expenses and allocations across months and years. It stores data locally on the server, offering a privacy‑focused alternative to cloud services. Users can import annual plans from Google Sheets and export their data as JSON, while a dashboard presents statistics, charts, and a Sankey diagram for visual analysis.

The interface supports light and dark themes, works as a Progressive Web App, and includes keyboard navigation for power users. Multi‑language and multi‑currency support make it usable in many regions, and a privacy mode masks sensitive information when used in public places. Customizable financial years and the ability to carry over budgets simplify multi‑year planning.

User management is handled through the app and a command‑line interface, and the system allows inline expression evaluation for quick calculations. The software is released under the MIT license, is open‑source, and can be deployed via Docker in seconds.
