Search for a net worth tracker and nearly every result has the same onboarding flow: "Connect your bank." Behind that button sits an aggregator such as Plaid or Finicity, and behind the aggregator sits a permanent, centralized copy of your transaction history that you can never fully claw back.

This article is about the other option — a net worth tracker without bank linking — how it works, what you give up, and why many people switch to it deliberately rather than out of privacy anxiety.

What "connect your bank" actually connects

When you link an account through Plaid, you hand your bank credentials to a third party that logs into your bank as you. The aggregator then:

• Pulls balances and transactions on a recurring schedule, forever.
• Stores them in its own infrastructure, mirrored again into each app you connected.
• Becomes a party to breach notifications you have no relationship with.

You cannot revoke access per-app cleanly, retention after deletion is policy-dependent, and the whole chain works only as long as the aggregator's screen-scraping or API access keeps functioning. None of this is hidden — it is simply normalized.

The no-Plaid alternative in one picture

A tracker without bank linking flips the direction of data flow:

| | Bank-linked tracker | No-Plaid tracker | |---|---|---| | Balances enter via | Aggregator sync | You type them | | Primary data store | Vendor cloud | Your browser | | Credentials exposed | Bank login to a third party | None | | Breach blast radius | Every linked user | Your device only | | Works offline | No | Yes |

You remain the integration layer — typically a five-minute weekly ritual of opening your brokerages and banks and updating the numbers. For most portfolios that is a handful of accounts.

What you genuinely lose (and gain)

You lose: automatic transaction categorization, real-time balance refresh, and spending insights computed server-side over years of history.

You gain: the habit. This is not a consolation prize. Manual entry forces you to look at every account weekly — which is precisely how people discover a forgotten subscription, a creeping fee, or a drifted allocation months earlier than an alert would have surfaced it. If you want to operationalize that habit, our 30-minute subscription audit turns it into a checklist.

You also gain: an answer to "what happens if the company shuts down?" that does not involve hoping someone migrates a database. A local-first tracker stores your data in your own browser, encrypted with a key derived from your master password — the vendor going away changes nothing about your ability to keep using or exporting your vault. The design details are in how your vault is encrypted.

How to pick a no-Plaid tracker

The "no bank link" label alone does not guarantee privacy. Check:

1. Where the data lives. It should be your device — for web apps, the browser's IndexedDB, encrypted before it is written.
2. Whether export is first-class. You should be able to leave with your data at any moment, in a format you control.
3. What the network tab shows. A truly local tracker makes no requests carrying your balances after sign-in. Verify it yourself.
4. Whether tracking is actually pleasant. Manual entry with a clunky UI dies in two weeks. Look for quick-add flows, keyboard support, and dashboards that make the weekly ritual feel worth it.

The bottom line

Bank-linked convenience is a real product, and for some people the trade is worth it. But it is a trade — permanent credential exposure and centralized storage in exchange for automation — and it is presented as a default rather than a choice.

If you would rather own the trade-off, LocalVault was built for it: net worth and subscription tracking, no bank linkage, AES-GCM encryption in your browser, and zero upload. See how it works — the free tier covers most personal portfolios.
