Use the model without surrendering the model inputs

Browser model inputs

The values entered into the browser models are calculated on your device and are not included in the workbook-request payload or analytics events. Do not enter brokerage credentials, account numbers, tax identifiers, personal records or confidential forecasts into a public browser tool.

Workbook delivery

When you request a workbook, we store your name, email address, requested asset and version, request time, source page, consent-text version, attribution parameters, a one-way hash of the requesting network address, and limited browser information used for abuse prevention. We use this information to deliver the requested file, record delivery status, prevent repeated abuse and answer a delivery request.

Marketing consent is separate

Workbook delivery does not subscribe you to marketing. The marketing checkbox is optional and unchecked. If you select it, the address is recorded as pending confirmation and must complete a separate confirmation step before marketing begins. A later withdrawal is recorded in the suppression history.

Analytics

When configured, analytics may record page views and aggregate interaction events such as a model recalculation or workbook request. Model inputs are excluded from event payloads.

Retention and requests

Delivery and consent records are retained only for operational, consent-evidence, security and legal needs. Reply to the workbook delivery email to request access, correction or deletion where applicable. Some minimal suppression or transaction evidence may be retained when required to honor an opt-out or legal obligation.

Security boundary

Workbook files are unlocked only after a valid delivery request. The service returns a short-lived download link and, when inbox delivery is available, may also send the workbook by email. The public pages do not expose permanent workbook-file URLs. No web form can make email perfectly risk-free; use a non-sensitive address and inspect attachments before opening them.
