Security & Privacy
Your Data is Safe With Us
We handle your financial data with the utmost care. Bank-level encryption, GDPR compliance, and strict AI data policies protect your information.
Enterprise-Grade Security
We use the same security standards as major financial institutions to protect your data.
Bank-Level Encryption
All data is encrypted with AES-256 at rest and TLS 1.3 in transit. The same standards used by major banks.
UK Data Centre (London)
Your data is stored in EU-based data centers (AWS eu-west-2, London) ensuring GDPR compliance and data sovereignty.
Secure Authentication
Industry-standard authentication with secure password hashing, session management, and optional two-factor authentication.
Row-Level Security
Every database query is automatically filtered to ensure you can only access your own company's data.
AI That Respects Your Privacy
We use AI to help categorize transactions, extract data from documents, and provide insights. Here's our commitment to you:
Never Used for Training
Your financial data is NEVER used to train AI models. Not by us, not by our AI providers.
Never Shared with Third Parties
Your data stays between you and AccountsOS. We never sell or share your data with anyone.
Processed, Not Stored
When AI processes your documents or transactions, it happens in real-time. We don't keep copies for AI use.
Minimum Data Principle
AI only receives the specific data it needs for the task at hand - nothing more.
Isolated Processing
All AI operations happen in secure, isolated environments with strict access controls.
Our AI Provider Commitment
Finn runs on Anthropic's Claude (chat) and Google's Gemini API (document and statement extraction), both on paid commercial terms under which your data is never used to train their models. All data is processed in line with GDPR requirements.
Secure Bank Statement Processing
When you upload bank statements, they're processed securely with multiple layers of protection:
- Encrypted upload
Files are encrypted during upload and storage using AES-256 encryption.
- AI processing in isolation
Statement data is extracted in secure, isolated environments and never stored by AI providers.
- No third-party sharing
Your financial data stays between you and AccountsOS. We never share it externally.
- Delete anytime
You can delete uploaded documents at any time, and the data is permanently removed.
All UK Banks Supported
Upload PDF or CSV statements from any UK bank. Our AI extracts and categorizes transactions automatically.
Barclays, Revolut, Starling, Monzo, HSBC, Lloyds, and more

finn@accounts-os.comBuilt for the agent era
AI agents are already finding AccountsOS.
That is not a problem, it is the point. AccountsOS is built AI-native: Finn runs on Claude Sonnet and Gemini, your own AI tools can plug into your books today, and when your business runs on agents, they will talk to Finn directly. You keep the dashboards. The agents get a handshake.
Finn's reasoning. The model accountants already use for advice, running your books.
Reads your receipts, statements and contracts. Vision built in.
Connect Claude to your books now. Ask your own AI about your numbers.
Your agents can talk to Finn directly. The handshake is already wired.
Your records stay in London. AI calls never train the models.
Every number above is live crawler and assistant traffic. Access to your books is scoped, sensitive actions require approval, and financial totals are computed rather than generated.
