Platform Methodology

Engineering

• Modern, type-safe stack with automated testing on critical calculation paths.
• Code review on every change; no direct-to-production commits on financial logic.
• Continuous deployment with automated accessibility, performance and SEO checks.

Content production

• Outlines reviewed against the financial-planning methodology.
• Drafts (including AI-assisted drafts) reviewed by a human editor.
• Citations to primary sources where regulatory or numeric facts appear.
• Dated "last updated" stamps on educational pages.

Quality assurance

• Calculator outputs spot-checked against independent reference implementations.
• Regression tests on flagship calculators before each release.
• Periodic review cycles for high-traffic and regulation-sensitive pages.

Operations

• HTTPS-only with modern TLS.
• Logged, access-controlled production environments.
• Incident response with post-mortems for material outages.

Governance

Editorial, methodology, privacy and security policies are maintained in the Trust Center and reviewed at least annually.
