Disclaimers

• Mast is not an official government service.
• Flag guidance can vary by country, state, agency, and local jurisdiction.
• Official proclamations, notices, or local policies should be treated as the final source of truth.
• AI summaries, date extraction, and calendar placement can be wrong and should be verified through the source button.

Mast collects and summarizes flag status information to make it easier to understand. It does not issue flag orders, interpret government authority, or replace official notices from the President, governors, agencies, courts, schools, military commands, municipalities, or other public bodies.

If you are responsible for a public building, school, business, municipal office, or formal ceremony, verify the current order with the relevant official source before acting.

Mast may use AI to summarize public flag orders and standardize event titles, descriptions, and date ranges. This can make orders easier to read, but it can also omit details, misunderstand context, or choose a date range that needs correction.

The AI summarized badge is a transparency notice, not a guarantee of accuracy. Use the source button for the official order or notice.

Mast refreshes source data on a schedule and displays the latest time that data was pulled. A source can be delayed, unavailable, blocked, changed without notice, or formatted in a way that an automated parser cannot fully read.

When Mast marks data as stale or a state source as degraded, it means the app may be showing cached or incomplete information. Treat that as a prompt to open the official source link.

State-level pipelines are connected source by source. Some states have clear current-status pages, while others publish news posts, bulletins, or archived orders that require interpretation. Stale or degraded state data may show cached notices alongside country-level or federal information.

Local orders, agency-specific orders, campus policies, tribal government notices, private property rules, and facility-specific instructions may not be included.

Calendar and timeline entries are based on known date ranges from official sources and recurring federal observances. They may omit newly issued orders, corrected orders, extended orders, or orders that were published in a format Mast cannot parse.

Dates are displayed for convenience and may not capture every local timing detail, such as sunrise, sunset, noon rules, time zones, or facility-specific instructions.

Multi-day orders are especially dependent on the source wording. Mast may show a continuing event across a calendar window even when the official source uses language tied to one ceremony, burial, observance, or publication date.

Browser, email, and SMS alerts are convenience notices. They may be delayed, blocked, missed, duplicated, or delivered after a source has changed. Morning updates are intended to send only when Mast knows of a flag order for the selected location, but they should not be treated as proof that no other order exists.

The Mast API is provided for convenience and automation. Do not use it as the sole authority for legal compliance, emergency operations, government ceremonies, public safety workflows, or other high-stakes decisions.

API responses can change as sources are added, parsers improve, and government sites update their publishing formats.

If you display Mast API data in another product, dashboard, sign, or workflow, include appropriate source context and do not remove warnings about stale, degraded, cached, or unofficial data.

Mast provides general informational content about flag status and etiquette. It is not legal advice, policy advice, or an official interpretation of the U.S. Flag Code or any state, local, agency, or institutional rule.
