Pro pricing 專業版定價
Pro adds workflow, not fortune — batch charts, report export, survey reproduction packs and a 10× API quota, on top of the same verifiable kernel that powers the free tools. Time-box passes never auto-renew.
Buy inside the Pro workbench: create a free account → Account → choose a tier. Checkout by Stripe.
What Pro unlocks
- Batch charts in the workbench — run a client list, not one form at a time.
- Report export — take the computed results out as documents.
- Survey reproduction packs — the practitioner workflow: reproduce a chart's inputs and survey data later, with provenance attached.
- Offline license key — Pro keeps working without re-login; the key is verifiable offline.
- 10× API quota — present your license key as a Bearer token on the public API for the raised tier. Free tier unchanged.
Tiers
| Tier | Price | Window | Renewal |
|---|---|---|---|
| Day pass | $4.99 | 24 hours | Never — expires automatically |
| Week pass | $9.99 | 7 days | Never — expires automatically |
| Monthly | $19 / month | Until cancelled | Monthly; cancel anytime in the portal |
| Yearly | $149 / year | Until cancelled | Yearly (two months free vs monthly); cancel anytime |
A pass is the honest shape for occasional work: pay for the window you need, and it ends itself. Subscriptions are for the practitioners who run the workbench weekly — and cancelling is two clicks in the billing portal, not an obstacle course.
The free tier is a charter, not a funnel
The calculators (flying stars, Kua number, Chinese zodiac), the daily almanac, and the free API tier stay free — permanently. Nothing on this site moves behind the paywall. Pro is additive workflow for people who use it professionally.
FAQ
What does Pro add?
Workflow, not fortune: batch chart processing, report export, survey reproduction packs, an offline license key, and a 10× rate quota on the public API when the key is presented as a Bearer token.
Does paying give more accurate readings?
No — and be wary of any service that implies it does. Every chart, free or Pro, is computed by the same verifiable kernel and carries the same provenance (engine version, ruleset id, SHA-256 input digest). Pro buys workflow and convenience, never different or "better" numbers.
Does the free tier change when I pay?
No. The free calculators, the almanac, and the free API tier stay exactly as they are — the free layer is a permanent charter of this site. Paid features are additive.
What is a time-box pass?
A fixed window of Pro access: the day pass runs 24 hours, the week pass runs 7 days. They expire automatically and never auto-renew — no surprise charges. Use them for a one-off batch job or a single client report.
How do I cancel a subscription?
Self-serve: the account page in the workbench has a Manage subscription button that opens the billing portal, where you can cancel at any time. Access continues to the end of the paid period.
How do I buy?
Open the Pro workbench, create a free account, and choose a tier on the account page. Checkout is handled by Stripe. Pro activates automatically once payment is confirmed.
