Data Source Policy
Tool Nova provides free browser-based calculators, converters, games, and public-data utilities. Some tools calculate results entirely in the browser, while other tools use public APIs or open data providers to show informational results.
How data is used
Tools that rely on public data may use sources such as weather APIs, NASA APIs, OpenStreetMap-related services, public library data, sports data, vehicle safety data, earthquake feeds, and other open information services. When a tool uses an external source, the page should describe the source, expected limitations, and whether results may be delayed or cached.
Many calculators and text utilities do not send user input to a server. They run directly in the browser and produce results from formulas, conversions, or local text processing.
Accuracy and limitations
Tool Nova tools are provided for general information, education, planning, and convenience. Results may not always reflect the latest official updates, and external APIs can be unavailable, delayed, rate-limited, or changed without notice.
Financial, health, safety, legal, weather, travel, space, sports, and emergency-related tools should not be treated as professional advice. Always verify important decisions with official sources or qualified professionals.
