Your saved profile can help Burn Board generate more relevant workout context, forecasts, benchmark planning, and alert behavior. The purpose is to make the app more useful before class — not to create a shadow profile for unrelated uses.
Burn Board keeps separate controls for workout-intel alerts and product-update emails. That means transactional notifications and marketing updates should not be treated like the same thing.
Login/security data should stay tightly separated from product personalization and outbound messaging systems.
The long-term target is a more durable, auditable, backup-friendly app data model with fewer risky runtime artifacts acting like source-of-truth storage.
