Effective and owner-reviewed: 14 September 2026. The Market Master owner has reviewed this policy against the services currently operating or technically activation-gated.

Educational and informational service
Market Master is an independent financial education and market-information portal. It is not a broker, trading venue, investment adviser, portfolio manager, personalized trading-signal service, custodian, exchange, or transaction-execution service. It does not accept deposits, hold client assets, connect to brokerage accounts, or place orders.
Content, research, market data, comparisons, tools, simulations, saved decision workflows, and AI-assisted features provide general educational information—not personalized investment, financial, trading, legal, accounting, or tax advice. If paid memberships are introduced later, payment would purchase access to information and workflow features, not advice, account management, investment performance, or a financial outcome.
Readers must verify material information independently and seek appropriately qualified professional advice when their circumstances require it.
Current services and provider roles
- Marketstack · active
- Supplies end-of-day market prices, history, volume, instrument metadata, and provider status. Requests are made and cached by the Market Master server; the provider API key is not exposed to visitors. Current displays are delayed and are not a real-time trading feed.
- OpenAI API · active
- Supports the research assistant, earnings workspace, market-move explanations, and clearly labelled AI commentary. Only the prompt and context required for the requested feature are sent. Public AI-generated text is identified as AI-generated and states whether human review occurred.
- WordPress and membership · free access active
- WordPress operates publishing, accounts, authentication, and saved service records. No paid subscription checkout is currently offered and no recurring payment is accepted. Paid Memberships Pro and Stripe are installed or prepared only for a possible later launch; their activation requires a separate legal, pricing, withdrawal, billing, and technical review.
- Email and form security · active
- FluentSMTP routes transactional email through the configured Market Master mailbox service. Cloudflare Turnstile protects public forms from automated abuse and processes the limited technical signals required to perform that check.
- Consent, analytics, and commercial features
- CookieAdmin Pro provides prior-consent controls and Google Consent Mode signals. Google Site Kit may load Google Analytics only after the applicable consent choice. Advertising and affiliate programs are not treated as active merely because supporting software or draft content exists. Any future activation requires updated notices, consent controls where applicable, and a clear disclosure beside each commercial link or placement.
Market and investment risk
Investing and trading involve risk, including possible loss of principal. Past performance does not guarantee future results. Products, protections, eligibility, tax treatment, and risks vary by provider and jurisdiction.
Marketstack data limitations
Current market displays use Marketstack end-of-day data. They are delayed, not a real-time trading feed, and may contain gaps, corrections, raw or adjusted values, ETF proxies, or unavailable fields. Source and session dates remain visible. Provider data must not be treated as an exchange-verified execution price.
OpenAI and automated-content disclosure
Research assistance, earnings analysis, market-move explanations, and Morning Brief commentary may be produced with the OpenAI API. AI output can be inaccurate, incomplete, or misleading. Public AI text is visibly labelled, cited where the workflow requires sources, and states when no human review occurred. Automated safeguards and moderation reduce risk but do not guarantee accuracy.
Calculators and models
Calculators and scenarios illustrate mathematical relationships using user inputs and visible assumptions. Straight-line returns, probability ranges, valuations, correlations, and stress cases are not forecasts, target prices, or promises of performance.
Commercial relationships
Advertising, memberships, and affiliate relationships may support the service. They are labeled and do not determine editorial conclusions, rankings, or research outcomes.
Sponsored and paid content
Material supplied or funded by a third party is labelled “Sponsored,” “Advertisement,” or another plain-language equivalent before a reader engages with it. Sponsorship does not remove the need for evidence, risk disclosure, and correction. A sponsor may not purchase an undisclosed editorial conclusion or present promotional copy as independent research.
