The Finthy browser extension exists for exactly three banks, all in Mexico:
- Banamex
- Banorte
- HSBC México
No other bank uses it. In the United States and Canada banks connect through Plaid instead; everywhere else, including every other Mexican bank, accounts are added and kept up to date by hand.
What it actually does
It reads transactions from your bank’s own website while you are signed in there, in your own browser. It does not hold your bank credentials and it does not log in for you. Finthy’s own description of it is the honest one: it “automatically captures transactions when you log into your bank’s website”.
This is not a background sync. Nothing arrives while you are away from your bank’s site. You decide how often your transactions update by how often you visit and run it.
Install it
The simplest route starts inside Finthy, because it puts you in the right place afterwards.
- Go to Banks and choose Add Bank, then Mexico.
- On Select a Mexican bank to connect, find Banamex, Banorte or HSBC México. Each shows “Syncs via browser extension” and a blue Chrome Extension badge.
- Click that badge. Finthy opens the setup with an Install from Chrome Web Store button. The extension is published on the Chrome Web Store and verified by Google.
- If you already have it, the same screen offers Extension Already Installed? and Open Bank Website, so you can skip straight to a sync.
Run a sync
- Visit your bank. Go to your bank’s website and log in as usual.
- Activate the extension. Click the Finthy extension icon and follow the prompts to sync your data.
- View it in Finthy. Your transactions appear in your Finthy dashboard within moments.
Repeat whenever you want fresh transactions.
What it needs
- Chrome, or another Chromium browser that installs Chrome Web Store extensions.
- A desktop browser. The extension cannot run in a mobile browser, so these three banks cannot be synced from a phone. You can still add transactions or import a statement from a phone.
- To be signed into your bank at the moment you run it.
Privacy
Your login credentials are never stored or shared, and the extension only reads transaction data. It does not move money, change anything at your bank, or read other pages.
Good to know
- It does not replace manual entry; it saves you typing. Anything it brings in behaves like a manual transaction, so you can edit every field afterwards, including the category.
- If you also import statements for the same account, Finthy compares the date, amount, description and running balance, and leaves an apparent repeat out of the import rather than creating a second copy. You can still choose to import it.
- If the bank redesigns its site, a sync can stop working until the extension is updated. The free route is always open: add the accounts by hand and import a statement.
- The free plan allows 2 bank connections and 4 visible accounts, and the extension does not change that.
