Use the tools as planning aids, not guarantees.
These terms set the basic expectations for using NumberCalendar. They are written in plain language so the limits of the product are easy to understand.
Educational use
NumberCalendar provides calculators, simulations, calendars, historical-data tools, and explanatory content for educational and planning purposes. The service does not provide individualized financial, investment, tax, legal, accounting, or gambling advice.
Your inputs and decisions
You are responsible for the values and assumptions you enter and for any decisions you make using the resulting estimates. A calculator result can be mathematically correct under its assumptions and still differ substantially from what happens in real life.
No guarantee of accuracy or availability
We aim to keep formulas, pages, and external data accurate, but errors, delays, outages, incomplete history, or model limitations can occur. Features may change, move, be corrected, or be removed as the product develops.
External and historical data
Where NumberCalendar displays external data, the source and update context should be shown where appropriate. Official recorded lottery results prevail if an external provider or NumberCalendar display disagrees with the official record.
Lottery tools
Lottery generators, statistics, calendars, checkers, simulations, and backtests are informational tools. Historical frequency, gaps, hot/cold labels, community systems, or simulated outcomes do not guarantee or imply a predictive edge in an independent future drawing.
Acceptable use
Do not attempt to disrupt the service, bypass access controls, scrape the site in a way that harms availability, abuse third-party data rights, or use the product for unlawful activity.
Intellectual property
NumberCalendar’s original interface, branding, explanatory text, and software are protected by applicable intellectual-property laws. Public facts, mathematical formulas, and appropriately licensed source data remain subject to their own legal status and source terms.
Changes to these terms
These terms may be updated as the product adds accounts, paid services, external datasets, or other material capabilities. Terms reviewed: September 8, 2026.
