> Do AI converters train on your files? Where terms allow it, how to opt out, and what that means for the account numbers in a bank statement.
Do AI converters train on your files? Some can, and the only reliable answer is in each site's terms and privacy policy. Look for wording that lets the company use uploads to improve its services or models, check for an opt-out, and avoid sites that stay silent. A bank statement is the wrong file to test vague terms with.

## What does training on your files mean for an AI converter?

Training on your files means an AI converter keeps the documents you upload, or the text pulled from them, and uses that data to build or tune the models it runs on. Your statement stops being a one-time job and becomes material the company works with long after your conversion is done.

### Conversion and training are different uses

Reading your file to produce a spreadsheet is the service you asked for. Every converter has to do that. Training is a second use: the company keeps a copy and feeds it, or labelled parts of it, into future versions of its software. One ends when you download your result. The other can last as long as the company keeps its training data.

### What training can involve

Training a document model often needs examples marked up by people, so staff or contractors may look at uploaded pages to label where the dates and amounts sit. It can also involve storing extracted text in datasets that are copied between systems. Neither is sinister in itself, but both mean more people and more systems touch your statement.

### Why companies want your files

Real documents are valuable. A converter that has seen thousands of statement layouts reads new ones better. That gives every converter a reason to want uploads, and a reason to write terms that allow it. Knowing that incentive exists is the first step in reading the terms with the right questions.

## Terms of service phrases that allow AI training on uploads

The terms of service phrases that allow AI training on uploads are rarely the words "we train on your files". They are broader: a licence over your content, permission to use it to improve services, or a promise that only "de-identified" data is kept. The table below translates the common ones.

The wording in the first column is a typical example of the pattern, not a quote from any particular site.

| Typical phrase | What it can allow | What to do |
| --- | --- | --- |
| "We use content you provide to improve our services" | Keeping uploads to tune or train models | Look for an opt-out, or pick another site |
| "You grant us a worldwide, royalty-free licence to your content" | Broad reuse beyond your conversion | Read what the licence is for; treat as a warning |
| "We may use de-identified or aggregated data" | Keeping text with names stripped, but amounts and merchants intact | Ask how they de-identify a statement |
| "Uploaded files are deleted after processing" | Usually no training on the file itself | Check whether extracted text or logs are deleted too |
| "We share data with service providers, including AI providers" | Sending your file to another company's model | Find out whether that provider may train on it |
| No mention of uploaded files at all | Unknown | Assume the file may be kept |

### Where to find the wording

Check the privacy policy, the terms of service and any separate "AI" or "data use" page. Search each one for the words "train", "improve", "model", "licence" and "content". It takes five minutes. If none of the three pages mentions uploaded documents, the company has not committed to anything.

### Reviews rarely cover this

Most reviews talk about accuracy and price, not data use. [How to read bank statement converter reviews](/blog/bank-statement-converter-reviews) explains which review sources are worth trusting, but the terms are still the primary document for this question.

## How do you opt out of AI converter training?

You opt out of AI converter training through a setting in your account, a written request to the company, or a paid or business plan whose terms exclude training. Not every converter offers any of these. If there is no opt-out and the terms allow training, the only reliable opt-out is not uploading.

### Look for a setting first

Some services put a data-use or "help improve our models" switch in account settings. If one exists, turn it off before your first upload, because an opt-out usually applies to future files, not files already used.

### Ask in writing

If there is no setting, email the company and ask three things: whether uploaded files or extracted text are ever used to train or improve models, whether you can opt out, and whether that applies to files already uploaded. Keep the reply. A company that answers clearly is giving you something you can hold it to.

### Business plans and the employer question

Some companies offer stricter data terms on business plans than on free or personal ones. If you are converting a statement at work, the employer's rules may decide this for you. [Converting a bank statement on a work computer](/blog/convert-bank-statement-on-a-work-computer) covers what to check before you do.

## AI converter terms that change after you upload

AI converter terms can change after you upload, and a company could try to widen how it uses data it already holds. The US Federal Trade Commission has warned that quietly changing terms to allow new uses, including AI training, can be unfair or deceptive. That warning protects you only if you notice the change.

### What the FTC said

In a February 2024 post on its technology blog, [the FTC wrote that quietly changing terms of service could be unfair or deceptive](https://www.ftc.gov/policy/advocacy-research/tech-at-ftc/2024/02/ai-other-companies-quietly-changing-your-terms-service-could-be-unfair-or-deceptive). It said a company that collected data under one set of privacy promises cannot simply go back on them through a retroactive change to its terms or privacy policy. The post names AI training as one of the uses behind such changes.

### What that means for you

The safest position is that your file was never kept in the first place. A converter that deletes your statement after you download the result has nothing to apply new terms to. A converter that keeps a history of your files does. When you get an email about updated terms from a site you used, read the section on content or data, not just the subject line.

## Account numbers in AI training data: the bank statement risk

The bank statement risk from AI training is that your account details, name and spending end up in a dataset you cannot see or recall. A trained model is unlikely to repeat a stranger's account number on request, but the training data itself is a store of real statements, and stores can leak.

### Where the exposure is

The risk is less about the model and more about the copies made to build it. Training sets get moved between teams, shared with labelling contractors and backed up. Each step is another place your statement lives, governed by policies you never read. If a dataset is exposed in a breach, every statement in it is exposed together.

### What redaction can do

Removing your address and account number before uploading cuts the most sensitive fields out of anything a converter keeps. It does not hide your transactions. [Who can see your uploaded files at a converter](/blog/who-can-see-my-uploaded-files) covers the staff and subprocessors that may touch a file, whether or not it is used for training.

### Documents with more at stake

Some statements carry more than your own data. A joint account shows a spouse's or partner's name and spending. Statements gathered for a visa or residence application are often joint, too. If you are preparing [joint bank statements for an immigration application](/blog/joint-bank-statements-for-immigration), the other person's privacy is in your hands as well, which is a reason to choose the strictest site you can find.

## AI converter mistake: a general chatbot used for statement conversion

A common AI converter mistake is pasting a statement into a general chatbot and asking it to make a table. It can work, but the chat app's terms decide whether your conversation is kept and used, and those terms were written for chat, not for financial documents. Its output also needs careful checking.

### Why it is a different risk

A chat history keeps the whole statement in your account, next to everything else you have asked. Depending on the service and your settings, conversations may be reviewed or used to improve models. Check the chat service's data settings before you paste anything, using the same phrase list from the table above.

### Accuracy is a second problem

A general chatbot can drop rows, merge two transactions or change a digit without warning. A converter built for statements can at least be checked against the statement's opening and closing balances. Whatever tool you use, add up the rows and compare them with the totals on the statement.

### A short decision rule

Use a tool whose terms say uploads are deleted and not used for training. If you cannot find that sentence, convert on your own computer instead. The FAQ at [CheapBankConvert](/) says statements are encrypted in transit and at rest and deleted once you have downloaded your file, which answers the deletion half of that rule; it says nothing about training either way, so ask. It is in early access, so check the homepage for its current status.
