Privacy policy

Last updated: July 2026 · Propability (propability.co)

What we collect

• Nothing identifying for the free simulator. Simulations run in your browser or app. Our first-party analytics store a daily-rotating anonymous hash (derived from your IP address and browser signature plus a secret salt) to count unique visitors — the raw IP address and browser signature are never stored, and the hash cannot be linked back to you after the day ends.
• Waitlist: your email address and the firm/market preferences you choose to share, used only to contact you about the product.
• Share cards: the simulation parameters you chose, stored so the shared link can render. No account required and none of it identifies you.
• Accounts (Pro): email address via our authentication provider (Amazon Cognito) and subscription status via our payment processor (Stripe). We never see or store card numbers.

What we don't do

• No third-party advertising or tracking pixels.
• No selling or sharing of personal data.
• No brokerage connections and no trading data in this product today.

Retention and deletion

Raw analytics events expire automatically after 90 days. Waitlist and account data are kept until you ask us to delete them — email privacy@propability.co and we'll remove your data within 30 days.
