Your Data, Your Rules: AI That Works Without Sending Data Anywhere

Here’s a question we hear from businesses evaluating expense tools: “Where does my data go?”

It’s a fair question. When an expense tool says “AI-powered,” that usually means your transaction data is being sent to an external service for processing. For some businesses – especially those in regulated industries, handling client financials, or simply privacy-conscious – that’s a dealbreaker.

We built a solution that gives you full control.

The AI Data Sharing Toggle

Every company account now has a simple setting: AI Data Sharing. It’s on by default (so existing workflows aren’t disrupted), but any company admin can turn it off with a single click.

For personal Pro accounts, the toggle is on the Profile page. For business accounts, it’s in Company Settings.

When you turn it off, here’s exactly what changes:

And here’s what stays exactly the same: CSV import, manual entry, report generation, expense claims, project allocation, tax calculations, currency conversion, data export – everything. The AI toggle only affects whether data leaves your account for external processing.

Pattern Matching: The AI You Already Have

Here’s what most people don’t realize: the majority of auto-categorization doesn’t use external AI at all. It uses pattern matching – a system that learns entirely from your own transaction history.

When you categorize a charge from Starbucks as “Coffee,” the system remembers. Next time a Starbucks charge appears, it matches the vendor name, checks the amount range, considers how recently you made a similar categorization, and suggests “Coffee” with high confidence. No external call needed.

The pattern matcher uses six signals to score each match:

• Description match – exact, merchant-level, or fuzzy text matching
• Historical frequency – how often you’ve categorized this vendor into each category
• Amount fit – does the amount match the typical range for this category?
• Transaction type – debit vs credit consistency
• Account preference – same bank account as previous matches
• Recurring detection – subscription-like patterns (consistent amounts, regular intervals)

After a month or two of use, pattern matching handles 80-90% of categorizations on its own. The external AI is really just a fallback for vendors you’ve never seen before.

What This Means in Practice

Turn off AI data sharing and use the Auto-Categorize button. It still works. It still suggests categories. The button label changes from “AI Auto-Categorize” to “Auto-Categorize.” The suggestion modal says “Pattern Match” instead of “AI Recommends.” The category dropdown shows “(Best Match)” instead of “(AI Pick).”

The functionality is the same. The data stays local.

For new vendors with no history, the system will say “No matching pattern found” and let you select a category manually. That one manual selection becomes the pattern for next time. The system builds its knowledge from your choices, not from an external model.

Privacy by Design

We believe expense data is sensitive. Transaction descriptions reveal where you eat, where you shop, what services you use, and how much you spend. Receipt images can contain vendor addresses, partial card numbers, and line item details.

When AI data sharing is enabled, we’re transparent about what gets sent:

• Transaction categorization: descriptions and amounts go to OpenAI
• Receipt scanning: receipt images go to OpenAI’s vision API

We never send your name, email, password, account balances, or financial totals. OpenAI’s API policy states that API inputs aren’t used to train their models.

But “we don’t misuse your data” is a weaker promise than “your data never leaves.” The toggle gives you the stronger option.

Who Should Turn It Off?

Most users won’t need to. The AI features are useful and the data handling is responsible. But consider disabling AI data sharing if:

• Your company has data residency requirements
• You handle client financial data subject to confidentiality agreements
• Your industry has regulatory constraints on third-party data processing
• You simply prefer that financial data stays within your account

The toggle is there whenever you need it. No judgment, no reduced functionality, no upsell to get the “private” version. It’s a checkbox.

The Best of Both Worlds

You shouldn’t have to choose between smart automation and data privacy. Pattern matching gives you intelligent categorization that improves with every transaction – built entirely from your own history, running entirely within your account.

And when you do want the full AI experience – receipt scanning, new-vendor categorization, the whole package – it’s one toggle away.

Your data. Your rules.
