Privacy Policy

Effective Date: May 1, 2026

1. Overview

FourPart is committed to protecting the privacy of the Advisors and their clients who interact with our platform. This Privacy Policy describes how we collect, use, store, and protect information when you use FourPart at fourpart.io.

FourPart is a B2B platform. Our primary users are professional Advisors. We are not a consumer-facing service.

2. Information We Collect

Account Information

  • Name, email address, and professional details provided during account registration.
  • Subscription and billing information (payment processing handled by Stripe — we do not store card numbers).

Client Financial Data

  • Trial balance files, accounting exports, and financial data uploaded by Advisors on behalf of their clients.
  • Analysis outputs, projections, scenario models, and override adjustments generated through the Platform.
  • Historical financial period data used to improve calculation accuracy for that same client.

Usage and Technical Data

  • Log data including IP address, browser type, pages visited, and actions taken within the Platform.
  • Event data such as analysis runs, file uploads, exports, and login activity, retained for security and audit purposes.

3. How We Use Your Information

We use collected information solely to:

  • Provide, operate, and improve the FourPart Platform.
  • Process billing and manage subscriptions.
  • Apply historical financial data to improve the accuracy of calculations and projections for that same client (first-party functional use only — not shared model training).
  • Maintain security and audit logs to detect unauthorized access.
  • Communicate with Advisors about their accounts, updates, and policy changes.

We do not sell, rent, or share your data or your clients' data with third parties for marketing, advertising, or any commercial purpose. We do not use Client Data to train shared AI or machine learning models.

4. Data Storage and Security

Client Data is stored on secured cloud infrastructure. We implement industry-standard safeguards including:

  • Encrypted data transmission (HTTPS/TLS).
  • Access controls limiting data access to authenticated account holders.
  • Audit logging of key data access and modification events.
  • Session management controls including automatic session expiration.

While we take reasonable precautions, no system is completely secure. We cannot guarantee absolute security of data transmitted over the internet.

5. Data Retention

  • Active accounts: Client Data is retained for the duration of the subscription.
  • Upon cancellation: Client Data is retained for 90 days to allow data export, after which it is permanently deleted.
  • Audit logs: Event logs and access records may be retained for up to 3 years for security and compliance purposes.

Advisors may request deletion of specific client data at any time by contacting admin@fourpart.io.

6. Third-Party Services

FourPart uses the following third-party services, each governed by their own privacy practices:

  • Stripe — payment processing. FourPart does not store payment card data.
  • Vercel — frontend hosting and delivery.
  • Railway — backend infrastructure and database hosting.
  • AWS S3 — file storage.
  • Clerk / NextAuth — authentication and session management.

We do not authorize these providers to use your data for their own purposes beyond the service they provide to us.

7. AI Features and Data Use

FourPart incorporates AI-assisted contextual narratives that appear alongside financial metrics. These narratives are generated to support advisor-client educational discussions and are not personalized financial advice.

The time-series intelligence features in FourPart analyze a client's own historical period data to develop more accurate calculations specific to that client's financial patterns. This is a functional computation performed on that client's data only — it is not used for cross-client benchmarking or to train shared AI models.

FourPart may maintain a proprietary library of intercompany account name patterns used for consolidation logic, derived from anonymized structural observations — not from specific client financial figures.

8. California Residents (CCPA Notice)

FourPart is a B2B platform serving professional Advisors. To the extent California's Consumer Privacy Act (CCPA) applies:

  • We do not sell personal information.
  • California residents may request disclosure of data collected, request deletion, and opt out of any sale (which we do not engage in).
  • To exercise any CCPA rights, contact admin@fourpart.io.

9. Multi-State Operations

FourPart may process financial data belonging to clients located in multiple U.S. states. We maintain consistent data handling practices across all jurisdictions. Advisors are responsible for ensuring their use of FourPart complies with applicable state laws governing the data of their clients.

10. Children's Privacy

FourPart is not directed at individuals under 18. We do not knowingly collect data from minors.

11. Changes to This Privacy Policy

Material changes will be communicated to registered Advisors via email at least 14 days before taking effect. The effective date at the top of this policy will reflect the most recent revision.
