What is Aeterna?

Why Aeterna?

Privacy First: Your financial data belongs to you. No cloud sync, no data mining, no third-party access. Everything stays on your device. We believe financial privacy is a fundamental right, not a premium feature.

Indian Rupee Support: Full en_IN locale support with proper ₹ currency formatting and Indian numbering system (lakhs, crores). Built specifically for the Indian market with local financial conventions in mind.

Offline-First: Works completely offline. No internet connection needed for any core feature. Your data never needs to leave your device unless you choose to back it up.

Multi-Platform: Available on Android, iOS, Web, Windows, Linux, and macOS — built with Flutter for a native experience on every platform. Your data stays in sync across devices through optional Google Drive backup.

Future Planning: Project your finances year-by-year with salary growth, investment allocation, and compounding calculations — up to 100 years into the future.
