Real humans, real response times. We treat support as part of the product — not a queue you get lost in.
Use whichever channel fits the urgency. All three land in the same inbox.
For modelling questions, replication issues, vintage diffs, or anything else. Include your run hash and a brief description — we'll dig in.

Quick answers to the questions we hear most. Email us if yours isn't here.
For Researcher subscribers: under 24 hours on business days, almost always within a few hours during European working time. For Institutional and Customisation: under 4 hours. We track every ticket against this SLA and report on it in your monthly summary.
The same person who wrote the solver answers your modelling questions. There is no “tier 1” ticket-shuffling layer. If your question is about Klein/Sims gensys, calibration, or a fan-chart edge case, the reply comes from someone who can debug it at the matrix level.
The most useful things are: (a) your run hash — the six-character vintage identifier — if you have one, (b) the model class and country, (c) what you expected vs. what you got, and (d) any error message or screenshot. The hash lets us reproduce your run exactly on our side.
Payments are handled by Paddle as our Merchant of Record. For billing, invoice, VAT, or refund questions, contact Paddle directly through the link in your receipt email, or write to us and we'll route it. Paddle's policy is documented at paddle.com/legal.

Monday to Friday, Indian-Ocean time (GMT+4). Saturday is covered for Institutional and Customisation tiers on a best-effort basis. We do not cover Sunday except for Customisation SLAs.
