Core Innovation¶

🧮 Daily Average Cost¶

An item costing ¥1000 used for 1000 days costs only ¥1/day. An item costing ¥100 used only once costs ¥100/day.

Cheap ≠ economical. Expensive ≠ wasteful. DailyCost Vault independently calculates the daily average cost for every item — across In Use, Sold, and Retired states — making "money-burning" assets visible at a glance.

📥 Smart Import from 3 Platforms¶

Drag and drop JD.com, Taobao, and Steam order CSVs. Dual parser (Rust backend + TypeScript frontend), auto platform detection, invalid order filtering, emoji matching, multi-item merge. Batch preload deduplication — tens of thousands of records imported in seconds.

🔒 Fully Local Data¶

SQLite database with local persistence, zero server dependency. Your spending data never leaves your device. No user accounts, no cloud sync, no telemetry. Export backups anytime.
