How It Works
How does Cashuary work?
Sign in with Google, connect your bank via Plaid, and you're done. Cashuary creates a dedicated calendar in your Google Calendar and syncs your transactions there as all-day events — automatically, in the background. You never need to open the Cashuary app again.
What shows up in my calendar?
Each transaction appears as an all-day event on the day it was authorized. You'll see the merchant name and amount. In daily summary mode, all transactions for a day are rolled into one event with a full breakdown when you tap it.
Do I need to manually refresh or sync anything?
No. Cashuary receives instant notifications from your bank via Plaid webhooks. New transactions appear in your calendar within minutes of being authorized — no manual refresh, no scheduled polls.
What are per-transaction and daily summary modes?
Per-transaction mode (the default) creates one calendar event per purchase. Daily summary mode rolls everything into a single event per day — useful if you want less calendar noise. You can switch between them at any time.
Can I connect multiple banks?
Yes. You can connect multiple bank accounts and assign each to a different calendar — for example, your work card to a "Work Expenses" calendar and your personal card to a separate one.
Security & Privacy
Can Cashuary move money or make transactions?
No. Plaid's connection is strictly read-only. Cashuary can see your transaction history and balances — nothing else. It cannot initiate transfers, make payments, or modify your accounts in any way.
How do you access my bank data?
Through Plaid, the same infrastructure used by Venmo, Robinhood, and thousands of other financial apps. Plaid handles the bank login directly — Cashuary never sees your banking username or password. Plaid gives us a read-only access token, which we use only to fetch transaction data.
How is my data protected?
Your Plaid and Google tokens are encrypted at rest using AES-256-GCM, an industry-standard encryption algorithm. Each token is encrypted with a unique initialization vector, so even if the database were exposed, the tokens would be unreadable without the encryption key.
Do you store my transaction data?
No. Raw transaction data is never written to Cashuary's database. We store only a cryptographic hash of each transaction ID — enough to detect duplicates and prevent double-posting, but not enough to reconstruct what you spent or where.
Your Data
What data does Cashuary actually store?
Your Google account ID (to identify you), encrypted access tokens for Plaid and Google (to fetch transactions and write calendar events), account metadata like the last four digits of your card, and transaction ID hashes for deduplication. No merchant names, no amounts, no balances — those go directly from Plaid to your Google Calendar.
What happens if I delete my account?
Everything is deleted: your user record, all connected bank items, account metadata, and transaction hashes. Your Cashuary calendar is removed from Google Calendar. Plaid access is revoked immediately so the read-only connection is terminated.
Does Cashuary sell my data?
No. Your data is used only to power your own calendar sync. It is not sold, shared with advertisers, or used for analytics. See our full Terms of Service.
Account & Setup
How long does setup take?
About two minutes. Sign in with Google (one click), connect your bank through Plaid (30 seconds), and transactions start appearing in your calendar automatically.
Does Cashuary work on mobile?
Yes. The syncing happens in the background — there's nothing to open. Your spending appears in the Google Calendar app on your phone just like any other event. The Cashuary setup app works in any mobile browser if you need to manage your connections.
What if my bank connection breaks?
Cashuary will show a "Reconnect" prompt in the app if your bank connection expires or is revoked. Clicking it walks you through the Plaid reconnection flow. Syncing resumes automatically once reconnected.
