FAQ
Plain answers, institutional posture.
Can I cite KEYSTONE. in my own publications?
Open: short, non-commercial excerpts with attribution. Data: no public citation — internal use. Professional: non-commercial citation with attribution across the catalogue. Single purchase: perpetual licence with commercial citation in the buyer's own professional deliverables. Every figure carries a traceable source line.
Why should I trust reconciled figures over the raw sources?
We don't replace raw sources - we expose the seams between them. When UN Comtrade and Eurostat disagree on a bilateral flow, both series remain visible and our bridge is documented.
How often do indicators update?
Monthly for trade data. Annually for annual-series dashboards and existing outlooks, with new outlooks released as they are completed. Every dataset carries a "last updated" stamp matching its source release date.
Do you cover minerals beyond natural stone?
Yes - from industrial minerals (feldspars, limestones, clays, metals…) to ornamental stone. Natural stone is the specialisation with deepest producer-level resolution.
Can I cancel or downgrade at any time?
Yes. Data and Professional billing stops at the next cycle. On the Professional annual plan and single purchases, downloaded PDFs may be kept for internal use after the subscription ends; on the Professional monthly plan reading is in the viewer, without download.
Can I try KEYSTONE. before subscribing?
The Open plan is permanent and free — it includes the world-stone and world-mineral export dashboards plus the UK Macroeconomic Outlook 2026–2030 as a full-text sample. Upgrade to Data for the full dashboard library, or to Professional when the data starts driving decisions.
