Frequently asked questions
What counts as a "run"?+
Each IFC upload you analyse counts as one run. Re-opening a saved analysis, exporting, or browsing history doesn't consume runs.
How does the annual discount work?+
Choosing annual billing locks in a 20% discount for the full year. You'll be invoiced once upfront. Monthly billing is available at the standard rate.
What happens to my data on the Free tier after 30 days?+
Free tier analyses are automatically deleted after 30 days. Upgrade to any paid plan for unlimited retention. Your account stays active — only old analyses are removed.
Can I upgrade mid-month?+
Yes. Upgrading mid-month is self-serve: complete checkout from Pricing and your new plan is active as soon as payment completes. Free-tier runs do not count toward your new plan's monthly quota.
Do you support purchase orders or invoicing?+
Team and Business customers can request invoice billing. Contact info@keplerworks.io with your firm details and preferred PO process.
What methodology does the Carbon agent use?+
A1–A3 product-stage embodied carbon aligned with BS EN 15978 thinking, geography-anchored factor resolution, and confidence scoring on every run. See About and the in-product methodology notes for detail.
