Privacy Policy

Your privacy matters

Last updated: February 2026. This policy explains how Kvantfin collects, uses, stores, and protects your information.

Information we collect

We collect information you provide directly, such as your email address and display name when you create an account. We also collect usage data automatically, including pages visited, features used, and device information (browser type, operating system).

  • Account data -- email, display name, and authentication credentials.
  • Usage data -- watchlists, followed stocks, prompts submitted to the AI engine, and interaction patterns.
  • Device and log data -- IP address, browser type, pages visited, and timestamps.

How we use your information

  • To provide, maintain, and improve the Kvantfin platform.
  • To generate AI-powered market analysis and watchlist syntheses.
  • To personalise your experience (e.g. followed stocks, watchlists).
  • To send service-related communications.
  • To detect and prevent fraud, abuse, or security incidents.
  • To comply with legal obligations.

Data sharing and third parties

We do not sell your personal data. We share data only with service providers that help us operate the platform:

  • Authentication providers (e.g. Supabase).
  • AI model providers for generating analyses (prompts are processed server-side).
  • Analytics providers (PostHog), if you consent to analytics cookies.
  • Cloud infrastructure providers for hosting and storage.

Data retention

We retain your account data for as long as your account is active. Usage data and generated analyses are retained for up to 12 months. You can request deletion of your data at any time by contacting us or using the account deletion feature in Settings.

Your rights

Depending on your jurisdiction, you may have the right to access, correct, delete, or export your personal data. You may also withdraw consent for optional data processing (such as analytics) at any time. To exercise your rights, contact us at the address below.
