To stop an AI finance app from accessing your bank accounts, revoke its connection in your bank’s connected-app or third-party access controls, then disconnect it in the app and any named data-sharing provider. If you also want old records erased, make a separate deletion request: disconnecting usually stops future sharing but does not necessarily delete data already collected.
What to do first
Use the bank’s own website or mobile app—not a link in an unexpected message—and sign in. Find the connected-app or third-party access controls. Menu labels differ by institution; try “Connected apps,” “Linked apps,” “Third-party access,” or “Security and privacy.” Note the finance app’s name and any intermediary named during setup, such as Plaid.
- Review the active connection at your bank. Check which app is listed and which accounts or data it can access.
- Revoke or narrow access. Remove the connection, or deselect accounts if the bank offers account-level choices. Save or capture the confirmation.
- Disconnect inside the finance app. Look under its account, bank connection, privacy, or security settings and use its disconnect control if available.
- Check the named data-sharing provider. If the setup identified a provider such as Plaid, use its consumer portal to review or disconnect the link as well.
- Request deletion separately if you want stored data removed. Ask the finance app—and, when relevant, the provider—to delete information already collected. Keep the confirmation.
- Verify the result. Check that the bank’s connected-app list and the app or provider no longer show an active connection. Continue reviewing statements and promptly report any transaction you do not recognize to your bank.
The Consumer Financial Protection Bureau (CFPB) advises that deleting an app does not stop data sharing, and changing your bank password may not end a service’s access. Use connection-management controls instead. See the CFPB’s guidance on sharing financial data.

Where to revoke a bank connection
At the bank
Start with the bank because its controls may let you remove a particular app’s authorization or limit which accounts it can reach. Chase’s documented route is Security Center, under linked apps and websites; menu names and availability can change, and this is a Chase-specific example, not a universal path.

Chase announced a Data Security Center on September 25, 2026, with controls to view apps, manage permissions and access duration, select eligible linked accounts, and unlink apps. The announcement describes a phased rollout, so the feature may not yet appear for every customer. Check Chase’s announcement and your current account interface.
At the finance app or data-sharing provider
The app may offer its own disconnect option. If a provider was named while you linked the account, check that provider’s controls too. Plaid says consumers can disconnect an account from an app through Plaid Portal. If that route does not work, Plaid directs consumers to its privacy request form. Provider procedures differ, so follow the current instructions for the provider shown in your connection flow.

Disconnecting is not the same as deleting data
Revoking a connection is about stopping future access or sharing. It does not necessarily erase bank information the app or provider has already received. Plaid distinguishes disconnecting an account from removing financial data from its systems; its Plaid Portal information describes managing access and separately removing data. The CFPB also recommends asking the service to delete collected data where applicable.

If deletion matters, make a distinct request to each relevant company and retain its response. A bank-side revocation, an app-side disconnect, and a data-deletion request address different things; do not assume that completing one completes the others.

What to check before approving a new connection
Before you authorize a finance app, read the consent screen and the app’s current privacy disclosures. The CFPB recommends understanding what data is requested, how it will be used or shared, and how to stop access or request deletion. Chase’s documented consent flow includes account selection and a summary of the account details to be shared.
- Which specific accounts and categories of information will be shared?
- How will the app use the information, and can it share it with other parties?
- How often will it access data, and for how long will authorization remain active?
- Does the requested permission allow payments or transfers, or only data access?
- How can you revoke the authorization and ask for previously collected data to be deleted?
Do not infer from an “AI” label that an app trains models on your bank data. Check the app’s current terms and privacy notice for its actual use, retention, onward-sharing, and model-training practices; the bank-linking guidance cited here does not establish a special revocation method for AI-branded apps.

What the revocation rule says—and what it does not
The CFPB regulation at 12 CFR § 1033.331 describes a reasonable method for revoking third-party authorization. It says a data provider that receives a revocation request through its method must revoke access and notify the third party in a timely manner. This provision should not be read as saying every bank, app, or connection is necessarily covered, or that a particular menu or interface is required.

If you still see access or an unfamiliar transaction
- If the connection remains listed, contact the bank through its official website or the number on your card and ask how to revoke that specific third-party authorization.
- If the bank no longer lists access but the app or provider still shows a link, contact that company and request written confirmation of disconnection.
- If your goal is data erasure, state explicitly that you are requesting deletion of previously collected financial data, not only disconnection.
- If a statement contains a transaction you do not recognize, contact your financial institution promptly and follow its dispute or fraud-reporting process.
