Security & Privacy
Your clients' documents are sensitive. Here's exactly how MAO handles them.
MAO uses purpose-built document AI to process financial statements — not a general-purpose language model. Your documents are never sent to OpenAI, Anthropic, or any other AI provider.
How MAO's AI works
MAO uses a specialised document intelligence engine trained specifically on the structure of financial statements. Unlike general AI tools, it doesn't interpret or generate text — it understands the layout, logic, and conventions of accounting documents and applies precise, deterministic transformations to them.
This means the output is predictable, auditable, and consistent every time. There are no hallucinations, no guesswork, and no surprises — just accurate rollforwards based on rules that mirror how an experienced accountant would approach the task.
What makes this different from ChatGPT-style AI
Large language models (LLMs) like ChatGPT work by predicting text statistically — they can be unpredictable, and using them with sensitive documents means sending that data to a third-party server. MAO's AI is fundamentally different: it's a closed, self-contained system with no external API calls, no model inference over the internet, and no reliance on any third-party AI provider.
MAO makes zero calls to any external service. No ChatGPT. No OpenAI API. No Google, Microsoft, or Anthropic. No analytics platforms with access to document content. When your document is processed, it stays entirely within MAO's own infrastructure — and is deleted immediately after your download.
Document handling
When you upload a document, it is processed entirely in memory on our server and returned to you immediately. The original file and the output are never written to disk and never stored. Once you download your file, nothing remains on the server — no document history, no content logs, nothing.
Can it work offline or self-hosted?
Yes. Because MAO has no external AI dependencies, it can be deployed entirely within your own infrastructure — on-premise or in a private cloud. If your firm requires that data never leaves its own network, a self-hosted deployment is straightforward. Contact us to discuss options.
Authentication & access control
Every account is protected by a securely hashed password. Sessions are encrypted and expire on logout. Access is controlled at the account level — you decide who gets in.
Infrastructure
MAO is hosted on AWS infrastructure in the EU region. All traffic is encrypted in transit via HTTPS (TLS 1.2+). The application runs in an isolated environment with no persistent document storage.
