Tracking spending

Fix a miscategorized expense (and teach Vault)

Correct a category once and Vault's on-device model learns it for next time.

Updated 2026-06-14

Vault guesses categories automatically, and it gets smarter the more you use it. When a category is wrong, fixing it takes a tap and quietly trains the app to your habits.

  1. 1

    Open the expense

    Tap the transaction with the wrong category.

  2. 2

    Change the category

    Tap the category and choose the right one.

  3. 3

    Save

    Your correction is saved and applied right away.

Your corrections teach Vault

Vault uses an on-device machine-learning model that learns from your corrections. Fix a merchant once and similar transactions are more likely to land in the right category next time.

Learning stays on your phone

The category model lives and retrains on your device. Your corrections, merchants, and amounts are never sent anywhere to improve it.
