Privacy Policy

When you sign in with Google, Cronos receives basic account details from Google such as your verified email address and display name so we can create and recognize your session.

If you subscribe, billing providers such as Stripe process payment details. Cronos receives subscription status, plan, and related billing metadata needed to unlock features—not your full card number.

Product usage may include account identifiers, plan quotas, strategy runs you save on the server, and technical logs needed to operate and secure the service.

We use account and billing information to authenticate you, apply plan entitlements, process payments or refunds through our providers, and communicate about your account.

We use research and portfolio inputs you provide to run historical simulations, portfolio replay, and related product features you request.

We may use aggregated or de-identified operational signals to keep the service reliable. Cronos is a research and simulation product, not a brokerage.

Some portfolio accounts, drafts, and related workspace state are stored in your browser (for example local storage) so you can continue work on that device.

Signed-in features may also store account, membership, and strategy-run data on Cronos servers so they remain available across sessions.

Clearing browser data removes local-only state. Server-stored account data remains associated with your signed-in identity until deleted or otherwise handled under these practices.

We share information with service providers that help us operate Cronos, including authentication (Google) and billing (Stripe), under their respective terms and our configuration of those services.

We do not sell your personal information. We may disclose information if required by law or to protect the security and integrity of the service.

Market chains, quotes, and portfolio marks shown in Cronos are historical research inputs used for simulation and replay.

They are not live brokerage executions, investment advice, or a guarantee of future results.

We retain account and billing records as long as needed to provide the service, meet legal obligations, and resolve disputes.

You can sign out at any time, manage billing through the Stripe customer portal when available, and clear local browser storage on your device.

This page describes current product practices in plain language. It is not legal advice, and details may change as the product evolves.
