什麼是 arc ？

arc is a privacy-first budgeting app where your data lives on your own server, protected by end-to-end encryption and biometric lock. Snap a receipt or type "coffee $5.50", and arc's AI creates the transaction and picks the category. arc enables envelope budgeting — allocate funds to categories, track spending in real time, and carry over unspent amounts. arc also lets you auto-log Apple Pay transactions or capture bank SMS alerts via Shortcuts, Tasker, or Zapier — no manual entry needed.
