Privacy Notice

How we handle your data

Prismark Systems / Lexicon Private Beta. Last updated June 2026.

Introduction

This privacy notice applies to the Lexicon Strategy Research Platform (SRP) from Prismark Systems, currently in Private Beta. It describes what personal data we collect, why we collect it, how it is stored and used, and what rights you have.

This is a private-beta operational privacy notice. It may be updated as the product and beta programme evolve. If material changes are made, we will update this page and notify active beta participants.

Why we use your data

We use the data we collect for specific operational purposes related to running the Private Beta:

Application review

To assess whether your workflow and research goals are a fit for the beta
To contact you about beta access or follow-up questions

Access management

To create and manage your beta user account
To authenticate your portal sessions
To control and revoke access when necessary

Feedback and product improvement

To understand how the platform works in practice
To identify bugs, confusion points, and missing features
To improve the product, documentation, and beta experience

Support and communication

To respond to support requests and technical issues
To send operational emails (application receipt, access invitations, feedback confirmations)

Security and operations

To log login events for security monitoring
To audit admin actions and system changes

Services we use

We use a small number of third-party services to run the beta. None of them are analytics or tracking services.

Supabase

Postgres database — stores application data, user profiles, feedback, and audit logs
Supabase Auth — manages beta user authentication sessions via secure JWT tokens
Hosted by Supabase (supabase.com)

Resend

Transactional email delivery — sends application confirmations, invitations, feedback receipts, and internal notifications
Resend (resend.com) delivers emails on our behalf. Email content is our responsibility.

Render

Web hosting — serves the Lexicon website and API
Render (render.com) provides the hosting infrastructure. It does not store application data.

Cookies and session data

We use only strictly necessary session cookies to manage authenticated access. We do not use tracking cookies, analytics cookies, or third-party cookies.

Portal session cookies

Set by Supabase Auth to maintain your beta user session
Contain encrypted JWT tokens with automatic expiry
Deleted when you sign out or the session expires

Admin session cookie

beta_admin_session — HMAC-signed admin session cookie
8-hour expiry by default
Used only to access the internal admin dashboard

How long we keep your data

Application data is retained while your application is under review and after the beta ends for operational record-keeping. Portal account data is retained while your account exists and for a reasonable period after access is revoked. Feedback data is retained as part of the product improvement record.

We do not currently publish specific retention periods per data category. As the product matures, we will clarify this further.

Your rights

You have the right to request access to, correction of, or deletion of your personal data. You may also ask questions about how we handle your data.

To exercise any of these rights, contact us at:

Beta and research-software note

Lexicon is Private Beta research software. It is not financial advice, not a signal service, not a broker, and not a profit system. Any backtest output should be treated as historical research for review.

By applying for or participating in the beta, you acknowledge that the product is being validated and that features, data handling, and this privacy notice may evolve.
