Privacy Policy

Last updated: January 13, 2026

What This Policy Covers

This privacy policy explains how Quantal collects, uses, and protects your personal and financial information. We believe in being transparent about what we do with your data.

Information We Collect

We collect information you provide directly:

  • Account information: Email address, password (encrypted), and name
  • Financial data: Income, expenses, categories, amounts, dates, and currencies
  • Household information: Household name, member invitations, and settings
  • Preferences: Currency settings, exchange rates, and display preferences

How We Use Your Information

We use your information to:

  • Provide and improve the Quantal service
  • Generate financial insights and comparisons
  • Send you important updates about your account
  • Respond to your questions and support requests
  • Ensure security and prevent fraud

AI Insights

When you use our AI insights feature, we send limited financial data without direct identifiers (such as transaction amounts, categories, and dates) to OpenAI to generate personalized recommendations. This data is processed according to OpenAI's privacy policy. We do not share your personal identifying information (such as name, email, or account details) with OpenAI.

Data Storage and Security

Your data is stored securely using Supabase, which provides:

  • Encryption in transit and at rest
  • Row-level security (RLS) so only you and your household members can access your data
  • Regular security updates and monitoring
  • Database backups

We never sell your data. We never share it with third parties except as necessary to provide the service (like OpenAI for AI insights, which we mentioned above).

Your Rights

You have the right to:

  • Access your data at any time through your account
  • Delete your account and all associated data
  • Export your data
  • Correct any inaccurate information
  • Opt out of AI insights (just don't use that feature)

Cookies and Tracking

We use minimal cookies for authentication and session management. We don't use tracking cookies or analytics that identify you personally. We don't use third-party advertising or tracking services.

Children's Privacy

Quantal is not intended for users under 18. We don't knowingly collect information from children.

Changes to This Policy

We may update this privacy policy from time to time. We'll notify you of significant changes by updating the "Last updated" date at the top of this page. Your continued use of Quantal after changes means you accept the updated policy.
