Privacy Policy

Last Updated: May 19, 2026

This Privacy Policy explains how Per Diem, LLC ("Per Diem," "we," "our," or "us") collects, uses, and shares personal information when you use the Per Diem mobile app, our website, and related support and account services (together, the "Services").

Per Diem is a personal finance and FIRE planning app. Our core service depends on handling sensitive financial information, so we aim to explain our data practices in plain language.

1. Scope

This Privacy Policy applies to information we process through the Services. It does not apply to websites, apps, or services that we do not control, even if they are linked from Per Diem.

2. Information We Collect

We collect the following categories of information:

  • Account and profile information. Name, email address, sign-in method, household setup details, and profile inputs such as birth year, filing status, risk tolerance, retirement assumptions, and household planning details.
  • Financial data. Account balances, account types, transactions, holdings, liabilities, income data, budgets, assets, goals, and FIRE planning outputs.
  • Subscription and billing status. Subscription entitlement status, renewal and expiration dates, and related account identifiers returned by our subscription infrastructure. We do not receive your full payment card number from Apple.
  • Device, usage, and diagnostics information. App version, operating system, device identifiers, push notification tokens, log data, crash information, performance data, and support diagnostics.
  • Support communications. Information you send when you contact support, including your message content and attachments you choose to provide.
  • Ask AI and connector content. If you choose to use Ask AI or connect Per Diem to a third-party AI assistant such as ChatGPT, Claude, or Grok, we collect your prompts where applicable, the responses returned to you, and the specific financial context retrieved to answer your question.

3. How We Collect Information

We collect information in the following ways:

  • Directly from you. For example, when you create an account, complete onboarding, edit budgets, add assets, contact support, or ask a question in Ask AI.
  • From connected financial accounts. When you connect an account, we receive financial data from the aggregation services and financial institutions you choose to use with Per Diem.
  • Automatically through the app and website. We receive technical and diagnostic information needed to operate, secure, and improve the Services.
  • From service providers. For example, authentication, subscription, observability, and infrastructure providers may return account, billing, or diagnostic information that helps us operate the Services.

4. How We Use Information

We use personal information to:

  • Provide the Per Diem app and your household workspace.
  • Import, organize, and display financial data you choose to connect.
  • Generate budgets, net worth summaries, account views, and FIRE planning outputs.
  • Process subscriptions and maintain premium access.
  • Authenticate users, prevent fraud, secure accounts, and investigate abuse.
  • Send transactional and service communications, including security notices.
  • Respond to support requests and troubleshoot product issues.
  • Maintain logs, detect crashes, and improve reliability and performance.
  • Provide Ask AI or a third-party AI connector when you choose to use it and have granted the required permission.
  • Comply with legal obligations and enforce our Terms of Service.

5. How We Share Information

We do not sell your personal information. We share personal information only as needed to operate the Services, at your direction, or when required by law.

Categories of third parties we may share data with include:

  • Authentication and database providers. We use Supabase for account authentication and managed database infrastructure.
  • Financial aggregation providers. We use providers such as Plaid and SnapTrade to connect and sync financial accounts that you choose to link.
  • Subscription infrastructure providers. We use RevenueCat to manage subscription status and entitlement state.
  • Infrastructure, security, and observability providers. We use service providers to host the Services, detect errors, monitor performance, and keep the product secure.
  • AI providers and connectors. If you choose to use Ask AI or connect Per Diem to a third-party AI assistant and grant permission, we share the data described in Section 6 with the AI provider or connector you selected.
  • Legal and business transfers. We may disclose information if required by law, to protect rights and safety, or in connection with a merger, financing, acquisition, or sale of assets.

We require service providers that process personal information for us to use it only for the services they provide to Per Diem and under contractual confidentiality, security, and data protection obligations.

6. Ask AI and Third-Party AI Providers and Connectors

Ask AI and third-party AI connectors are optional. They are not used automatically. Before Per Diem sends personal or financial data to a third-party AI provider or connector, the app presents a disclosure and asks for your permission.

When you choose to use Ask AI or a third-party AI connector, Per Diem may send:

  • Your Ask AI prompts and follow-up questions, where applicable.
  • Relevant financial context needed to answer your question, which may include balances, transactions, budget categories, income, holdings, and FIRE plan outputs.
  • The provider you selected in Integrations.

The third-party AI providers and connectors supported by Per Diem currently include:

  • OpenAI, L.L.C. (including ChatGPT connector access)
  • Google LLC (Gemini)
  • Anthropic, PBC (Claude)
  • X.AI LLC (Grok connector access)
  • Groq, Inc.

If you change AI providers in the app or connect a new third-party AI assistant, Per Diem asks for permission again before sending data to the new provider or connector.

7. Retention

We retain personal information for as long as necessary to provide the Services, maintain your account, comply with legal obligations, resolve disputes, and enforce our agreements. Retention periods vary based on the type of information and applicable legal requirements.

8. Your Choices

  • You can disconnect financial accounts from within the app.
  • You can withdraw Ask AI permission in Integrations.
  • You can revoke third-party AI connector access from Integrations or from the connected assistant's settings or account controls.
  • You can disable push notifications in your device settings.
  • You can delete your household from within the app settings.
  • You may contact us to request access to, correction of, or deletion of information, subject to legal and operational requirements.

9. Security

We use administrative, technical, and organizational measures designed to protect personal information. No security system is perfect, and we cannot guarantee absolute security.

10. Children's Privacy

Per Diem is intended for adults and is not directed to children under 18. We do not knowingly collect personal information from children under 18.

11. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will post the updated version here and update the "Last Updated" date.
