Purpose and scope
Wenbu offers traditional symbolic calculators, learning material and optional AI reflection. It does not guarantee future events or provide medical, legal, investment or psychotherapy services.
You remain responsible for real-world decisions. Do not use a chart to determine another person’s eligibility for employment, credit, education or other high-impact opportunities, or as evidence for an accusation.
Respect information and service limits
Only submit information you are entitled to use. Obtain permission before submitting another person’s details and omit unnecessary names, contact information and sensitive data.
Do not bypass limits, exhaust shared AI allowances, attack the service or use it to infringe others’ rights. Public API and MCP access are subject to reasonable-use limits that may change with load or maintenance.
Cost and availability
Charts, casts, draws and the local journal are currently free. AI readings and Agent conversations have published allowances. There are no current subscriptions or paid result unlocks. Service availability depends on maintenance, network conditions and model access. Free use does not include unlimited calls or guaranteed predictions.
Calculations and saved records do not use the AI allowance. Calculations still need a network connection. Export local records to keep your own backup.
