Professional, local-first calendar with Tamil mode support.
Most modern calendar applications rely heavily on cloud servers. Every event you create, every meeting you schedule, and every note you attach is sent to a remote server database (like AWS or Google Cloud). This creates significant privacy and security implications.
This calendar is built on a Local-First Architecture. This means the primary, authoritative database for your events is stored entirely inside your physical device, not on a server.
To achieve this, the tool uses IndexedDB, a low-level API provided by all modern browsers for client-side storage of significant amounts of structured data.
Unlike cookies or localStorage (which are limited to a few megabytes of text), IndexedDB is a fully-featured, indexed NoSQL database living directly in your browser. This is what allows you to store thousands of calendar events locally without ever triggering a loading spinner or requiring an internet connection.
Because the database is physically located on the exact same machine rendering the UI, latency drops from hundreds of milliseconds (server round-trip) to virtually zero. Data reads and writes happen instantly, creating an incredibly fluid user experience.
In a Local-First Architecture, where is the primary, authoritative source of your data stored?
