Our approach
to security & privacy

From protecting sensitive model data to safeguarding your work, security is built into how Formuly operates, with controls that are continuously tested and improved.

Your data, under your control

Your Excel workbooks stay on your computer by default. Formuly works primarily with model structure rather than sensitive financial inputs, and storing workbook versions with Formuly is entirely optional.
AI with clear boundaries

Formuly uses AI to assist with modeling, not to take unrestricted control of your work. Data shared for AI processing is limited, outputs are checked before use, and your information is never used to train AI models.

Your workbooks, protected

The integrity of your financial model matters as much as the confidentiality of its data. Formuly applies safeguards to AI-generated formulas and workbook changes, helping protect the calculations and structures you rely on.
Secure access, familiar sign-in

Formuly uses your organization’s existing Microsoft work accounts, including multi-factor authentication and established access policies. No separate passwords, and no unnecessary access to your organization’s information.

Secure infrastructure, built to be accountable

Formuly’s cloud services run on Microsoft Azure in Australia, with encryption, controlled access, monitoring, and recovery measures in place. Changes to our infrastructure and software are reviewed and tested before release.
Security that’s tested, not just promised

We don’t rely on checklists alone. From vulnerability assessments to testing access controls and reviewing code changes, we actively challenge our security measures to confirm they work as intended.

Have questions?

Answers to common questions about how Formuly protects your models, handles sensitive data, and meets your organization’s security requirements.

Where is my data stored?

Your workbooks stay on your own computers. Formuly's cloud services run on Microsoft Azure in Australia East, replicated to Australia Southeast, and keep a structural description of your model: the names, units, and timing of its line items. Whole workbook files are stored with Formuly only if you turn on workbook versions, which is off by default.

Is my model data used to train AI?

No. Formuly doesn't allow your content to be used to train AI models unless you expressly agree. The language model behind Formuly is provided by Anthropic, which keeps no request content and doesn't train on it.

Can Formuly access or modify my existing Excel workbooks?

Formuly works inside Excel, on the workbook you have open. When it suggests a change, you see exactly what will change, and why, before you accept it. Your workbook files stay on your machine unless you turn on workbook versions.

How does Formuly manage user access and authentication?

You sign in with your existing Microsoft work account. Your analysts join as Microsoft Entra guests and authenticate against your own directory, under your multi-factor authentication and access policies. There are no separate passwords to manage.

How does Formuly protect sensitive deal information?

Your input assumptions stay in your workbook. The numbers in your cells are masked before any request reaches Formuly's AI services, so the language model works from your model's structure: its labels, layout, units, and formulas. Data is encrypted in transit and at rest.
