Broker call transcripts and AI data leakage: what a recorded client call gives away in ChatGPT or Claude.

Many brokerages now record client calls and transcribe them so that the file shows what was said. A transcript is the most candid document in the file: clients talk about their jobs, their nerves, their families and their money in their own words, and the broker talks through the advice. Staff paste transcripts into ChatGPT or Claude to produce file notes and action lists. This page marks every item in a routine broker and client call transcript that the National Consumer Credit Protection Act and the Privacy Act bear on, and shows how the same transcript becomes a file note on Ermos inside the brokerage.

The broker and client call transcript

Produced after a recorded client call. ASIC’s RG 273.165 expects records of relevant conversations with the consumer and RG 273.167 lists audio recordings and file notes of conversations among the forms of record, so the recording and the transcript can be part of the evidence that the best interests duty was met.

What leaves the brokerage

  1. 1
    The speakers

    Three named people, recorded. Everything said below is attributed to them. Privacy Act guide.

  2. 2
    Income in the clients’ words

    Base pay, overtime and a spouse’s salary, spoken aloud. Financial information the broker asks about because section 117 requires reasonable inquiries into the consumer’s financial situation. Privacy Act guide.

  3. 3
    A job worry about a named employer

    A client’s fear about his employer’s tender and about colleagues who left. Said in confidence to get the loan right, and damaging if repeated. Privacy Act guide.

  4. 4
    A late payment and the explanation

    The credit history point and the client’s account of it. Credit information, which Part IIIA of the Privacy Act regulates when it comes from a credit report. Privacy Act guide.

  5. 5
    A family gift and a request for secrecy

    The donor, the amount, where it came from and an instruction not to contact a relative. A third person’s finances and a family confidence. Privacy Act guide.

  6. 6
    A private family plan

    A statement about trying for a child and the working hours that would follow, and a spouse’s wish to keep it off the form. Family plans of this kind are private personal information. They would be health information only if they disclosed something about a person’s health or a health service. Patient data guide.

  7. 7
    The spoken consents

    The broker’s request, and the clients’ answers, about recording and credit checks. The evidence of what the clients agreed to, which does not on its face reach an AI provider. Privacy Act guide.

  8. 8
    The broker’s advice and a promise

    The statement about lender policy, the card closure and a commitment to check policy before lodging. The advice that section 158LA covers, and the sentence a later complaint may turn on.

  9. 9
    Identity confirmations spoken aloud

    A date of birth and a home address read into the record. Identity verification data, now in a transcript. Privacy Act guide.

What happens in Frontier Models (ChatGPT, Claude)

  • The whole document is transmitted to the provider’s servers. On personal plans the user cannot choose where it is stored or processed, and for the major providers that has generally meant outside Australia, under that country’s legal process. Some business plans offer storage in Australia, but the provider still receives the content.
  • On consumer tiers, prompts can be retained and used to train future models.
  • The provider’s staff and systems can reach the content under the provider’s own policies.
  • Once sent, the brokerage no longer controls it. Retention and deletion happen on the provider’s terms.

The same document on Ermos

Ermos Dominion

The document is drafted on a unit in your office, from your own templates and the client file. Every marked item stays on the unit, which keeps working with the internet switched off. Nothing in it is transmitted to an AI provider, so there is no disclosure to analyse: the confidentiality work is the same as for your file server.

Ermos Edge

Your documents, the index and your access boundaries stay on your own instance in an Australian data centre. When a staff member asks for this draft, only their question and the excerpts they are permitted to see go to a named Australian provider, who is contractually barred from keeping the content or training any model on it. Nothing is processed outside Australia.

Common questions

Do ChatGPT and Claude use the information in a broker and client call transcript?
A transcript pasted in goes to the AI company's servers and is processed there to produce a reply. As at October 2026, whether a conversation on a personal plan (ChatGPT Free, Plus or Pro; Claude Free, Pro or Max) can be used to train the models depends on a setting each user controls. Business plans (ChatGPT Business and Enterprise, Claude Team and Enterprise) and the developer APIs sit under commercial terms, and OpenAI and Anthropic each say they do not train on that content by default (OpenAI, Anthropic). On either product, the thumbs up and thumbs down buttons can send a whole conversation back for training. This one holds a date of birth and a home address read aloud, a job worry about a named employer, a family gift and a private plan about working hours.
Is it safe to paste a broker and client call transcript into ChatGPT or Claude?
No, because people say things on a call that never reach the form. The Office of the Australian Information Commissioner (OAIC) recommends in its guidance on commercially available AI products that organisations do not enter personal information, and particularly sensitive information, into publicly available generative AI tools, because of the significant and complex privacy risks. Daniel's worry about his employer's lost tender, Sophie's request that her mother not be emailed about the gift and a family plan are all in the clients' own words. The spoken consents covered recording and credit checks, which does not on its face reach an AI provider.
Is it safe to use an AI note-taker or meeting recorder for a broker and client call?
Not until the brokerage knows where the recording is stored, whether the vendor trains a model on it and who can review it. Recording and transcription tools send the audio or transcript to the tool's vendor, so each of those questions needs an answer first. The OAIC's guidance also tells organisations to review carefully the terms and settings that will apply to their use of any AI product. A call with Daniel and Sophie also holds spoken consents and a family plan that one client did not want on the form.
How can a mortgage brokerage use AI for a broker and client call transcript without sending it to ChatGPT or Claude?
Ermos is built so the document stays under your control. On the Dominion AI unit it is drafted inside your office and none of it is sent to an AI provider. On Ermos Edge your documents and index stay on your own instance in an Australian data centre, and only the question and the excerpts the user is permitted to see go to a named Australian provider that is contractually barred from keeping them or training any model on them. A summary or file note is drafted from the transcript on the client file and the brokerage's own template. The broker checks it against the recording and signs it.
Is a call recording a record the brokerage should keep?
ASIC's RG 273.167 lists audio recordings and file notes of conversations among the forms of record a mortgage broker may keep, and RG 273.165 expects records of relevant conversations with the consumer. It is guidance rather than law, and the length of retention depends on factors such as the loan term. The recording is part of the evidence if the advice is questioned.
Does the accuracy of a transcript matter?
Yes. APP 10.2 requires an APP entity to take reasonable steps to ensure that personal information it uses or discloses is accurate, up to date, complete and relevant for the purpose. An automated transcript can mishear a figure or a name. A file note built on it should be checked against the audio before the brokerage relies on it.
Does the best interests duty extend to what is said on the phone?
The duty in section 158LA or 158LE applies to the credit assistance, which includes advice given orally. RG 273 notes that contemporaneous records help a broker show how it acted. What the broker said about lender policy, structure and risk on the call is part of the assistance, which is why the transcript matters.
