How AI2Fin protects your data
Security, privacy & compliance
2Fin handles sensitive banking and tax data. Security and privacy are engineered into every layer — from encryption and runtime self-protection to strict per-user data isolation and data minimisation. Here is how your data stays protected, in plain terms.
How your data is protected
Security at 2Fin is a continuous program, not a checkbox. Here is what protects your data — and how that protection is verified.
Your data is encrypted in transit and at rest
Everything you send to 2Fin travels over TLS-encrypted connections, and your financial data is encrypted at rest with AES-256. Backups are encrypted too. Encryption isn’t a setting to switch on — it is the default state of your data on the platform.
Your bank login never reaches 2Fin
2Fin never sees or stores your banking credentials. Bank connections run through dedicated connection providers that you authorise directly, and only read-only transaction data flows back to the platform. 2Fin can categorise and analyse your spending — it can never move money, initiate a payment, or make a transfer on your behalf.
Intelligence that respects your privacy
Categorisation works from a minimised, identifier-stripped view of your data — the rows involved are processed and not retained, and Fin does not train models on your data. In the desktop app, on any plan, you can bring your own provider key, so intelligence requests go straight from your machine to your provider.
Your billing is handled by specialists
When you subscribe to 2Fin, card billing is processed by a PCI-DSS Level 1 provider — the highest level of card-security certification. Your full card number is never seen by, or stored on, 2Fin’s servers.
Your data belongs to you
You can export your data at any time, and you can ask 2Fin to delete it. Once you do, it is removed on a defined timeline — including from backups as they cycle out. Your data is yours; 2Fin is the custodian while you use the product.
Your sessions are protected
Sign-in uses industry-standard OpenID Connect / OAuth 2.0 with multi-factor authentication. Sessions can be revoked at any time, and signing out invalidates your session on the server — not just in your browser.
Security is tested continuously — not once a year
2Fin runs continuous automated security testing — static analysis and dependency scanning — alongside runtime application self-protection (RASP). Internal security reviews identify and remediate issues as they are found. Independent third-party penetration testing and formal certification are actively progressing as 2Fin grows. In keeping with responsible disclosure, findings are handled privately and a summary is available to qualifying partners on request.
Rather hold the keys yourself?
Everything above protects your data on the platform. The other option is for it never to arrive: the desktop app keeps your records in a folder on your own machine, and a self-hosted build runs on infrastructure you operate. Both are claims you can test rather than take on trust.
Certifications & assurance
2Fin’s program status, stated honestly.
Automated static-analysis and dependency scanning run continuously, alongside runtime application self-protection (RASP) and internal security reviews with remediation.
Built to global privacy standards — the GDPR and other applicable data-protection laws.
Independent certification such as SOC 2, and third-party penetration testing, are actively progressing as 2Fin grows.
2Fin’s providers are independently certified (SOC 2, ISO 27001 and PCI-DSS among them). Certification evidence is shared with partners and enterprise customers under NDA.
Privacy & data handling
2Fin works with specialist, independently certified providers — each an industry leader in its craft, chosen as the best partner for one specific job, and given only the minimum data that job needs. Where data is used for intelligent categorisation, its direct identifiers are stripped before it leaves. 2Fin is a global platform, built to serve customers wherever they are — everyone is welcome.
2Fin practises data minimisation throughout. Any limited processing by its providers happens under Data Processing Agreements, with Standard Contractual Clauses applied to international transfers, and on pseudonymised data wherever possible.
The categories of providers 2Fin relies on, the regions involved, and its international-transfer safeguards are set out in the Privacy Policy. For a detailed, current list of sub-processors with their certifications and agreements, contact privacy@ai2fin.com.
Common questions
Is my financial data safe with 2Fin?
Yes. Your data is encrypted in transit and at rest (AES-256), protected by continuous automated security testing and runtime self-protection, and isolated per user. 2Fin never stores your banking credentials and can never move money.
Does 2Fin store my bank login or move my money?
No. Bank connections run through dedicated connection providers that you authorise directly. 2Fin receives only read-only transaction data and has no ability to initiate payments or transfers.
Does 2Fin use my data to train models?
No — Fin does not train models on your data. Categorisation requests carry a minimised, identifier-stripped view of the rows involved, are processed by enterprise model providers, and are not retained. In the desktop app, on any plan, you can bring your own provider key, so those requests go straight from your machine to your provider. And if you would rather intelligence requests never involve Fin at all, the desktop app runs 100% locally with every connection switchable.
Where is my data stored, and who is it shared with?
Your data is hosted with independently certified providers and protected by encryption, strict access controls and data minimisation. The categories of providers 2Fin relies on, the regions involved, and its international-transfer safeguards are set out in the Privacy Policy — and a detailed, current list is available on request.
Is 2Fin compliant with privacy regulations?
2Fin is built to align with the GDPR and other applicable data-protection laws — including the UK GDPR, India's DPDPA, and Australia's Privacy Act where they apply. Independent certification such as SOC 2, and third-party penetration testing, are actively progressing as 2Fin grows.
Responsible disclosure
2Fin welcomes responsible disclosure from the security community. If you believe you have found a vulnerability, please email security@ai2fin.com with enough detail to reproduce the issue.
Please allow 2Fin a reasonable opportunity to investigate and remediate before any public disclosure, and avoid accessing or modifying data that is not your own. For privacy or data-handling questions, contact privacy@ai2fin.com.
