Legal Terms

This Privacy Policy explains how Leroy collects, uses, shares, and protects information when you visit the site, create an account, subscribe, use research tools, request exports, play public games, submit feature requests, or contact us.

If you do not agree with this policy, do not use Leroy.

• Account information, such as your name, email address, login credentials, account settings, access tier, and session information.
• Billing and subscription information, such as plan, purchase history, subscription status, invoices, billing contact details, tax details, and Stripe customer identifiers. Stripe processes payment-card details; Leroy does not store full card numbers.
• Product activity, such as simulations requested, research views opened, paper experiments configured, export requests, game attempts, feature requests, votes, support messages, and administrative audit events.
• Technical information, such as IP address, browser type, device type, approximate location derived from network data, pages viewed, referring pages, timestamps, and diagnostics.
• Communications you send to us, including email, support requests, feedback, and legal requests.

Do not submit brokerage credentials, Social Security numbers, government identification numbers, bank-login credentials, health information, or other sensitive personal information unless Leroy expressly asks for it through a secure product workflow.

Leroy uses Google Analytics to understand aggregate site usage, traffic sources, page performance, and product-interest patterns. We also use Meta Ads and Reddit Ads for campaign measurement, conversion tracking, and marketing effectiveness. Each provider may receive information about visits, devices, browsers, events, and conversions when its tools are active. Google describes how it handles information in the Google Privacy Policy. You can also review Google's Google Analytics opt-out browser add-on.

Leroy may use essential cookies or similar storage for authentication, session security, preferences, fraud prevention, checkout, and service operation. Stripe may set cookies or collect device information when checkout, billing, or subscription management is used. Meta and Reddit may set advertising or measurement cookies, pixels, or similar technologies. We also use Sentry for error, performance, and security monitoring; Sentry may receive technical diagnostic data such as browser, device, request, and error information, but it is not used by Leroy to serve advertising.

Stripe is used for checkout, payments, subscription management, billing, fraud prevention, tax support, receipts, and payment dispute handling. Stripe may collect and process payment, billing, device, transaction, and fraud-prevention information under its own terms and privacy practices. Review the Stripe Privacy Policy and Stripe Privacy Center.

Sentry helps us detect, diagnose, and investigate application errors, performance problems, and security issues. Sentry may process technical information associated with an event, such as a timestamp, URL, browser or device details, request metadata, stack traces, and identifiers needed to correlate an incident. Review the Sentry Privacy Policy.

• Provide, operate, secure, maintain, and improve Leroy.
• Create and manage accounts, authentication sessions, subscriptions, billing, upgrades, and access tiers.
• Run simulations, research views, paper experiments, model comparisons, exports, feature requests, and product analytics.
• Measure site performance and public marketing effectiveness with Google Analytics, Meta Ads, and Reddit Ads.
• Detect, prevent, investigate, and respond to abuse, fraud, security incidents, policy violations, or technical failures.
• Communicate with you about your account, purchases, service updates, support, legal notices, and administrative messages.
• Comply with legal, tax, accounting, security, and regulatory obligations.

We do not sell personal information for money. We do not use third-party advertising networks on the site. We may share information with:

• Stripe, for checkout, billing, subscription management, tax, fraud prevention, receipts, and disputes.
• Google Analytics, for aggregate usage measurement and analytics.
• Meta Ads and Reddit Ads, for campaign measurement, conversion tracking, and marketing effectiveness.
• Sentry, for error, performance, and security monitoring.
• Infrastructure, hosting, database, security, email-delivery, logging, diagnostics, and operational service providers that help run Leroy under appropriate confidentiality and security obligations.
• Professional advisers, legal authorities, or other parties when reasonably necessary to comply with law, enforce terms, protect rights, prevent harm, or complete a business transfer.

We keep information for as long as needed to provide the service, maintain accurate records, comply with legal and accounting obligations, resolve disputes, enforce agreements, prevent abuse, and preserve security. We may retain de-identified, aggregated, or non-personal research and analytics data.

You may contact legal@getleroy.com to request access, correction, deletion, export, or restriction of personal information, or to object to certain processing. We may need to verify your identity before acting on a request. Some information may be retained where required for security, billing, tax, legal, dispute, or operational reasons.

You can manage billing through Stripe-powered account tools when available. You can also use browser settings to limit cookies, though disabling essential cookies may break login, checkout, or product functionality.

We use reasonable administrative, technical, and organizational safeguards intended to protect information. No internet service, database, or transmission method is perfectly secure, and we cannot guarantee absolute security.

You are responsible for using a strong password, keeping your account credentials confidential, and promptly notifying us if you believe your account has been compromised.

Leroy is not intended for children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact legal@getleroy.com.

Leroy is operated from the United States. If you use the service from outside the United States, your information may be transferred to, stored in, or processed in the United States and other countries where our service providers operate.

We may update this Privacy Policy as the product, laws, or operations change. The updated version will be posted on this page with a new “Last updated” date. Material changes may also be communicated through the site or account email when appropriate.
