A subscription to the Elementarium finite element workspace, described on the pricing page and governed by the terms of service. Payments are processed by Stripe. Prices, plan limits and cancellation terms are as published at the time you subscribe.

Supervisory authorities

Trade licensing — the competent municipal trade licensing office for the registered seat above.
Consumer protection — Česká obchodní inspekce (Czech Trade Inspection Authority), coi.cz.
Data protection — Úřad pro ochranu osobních údajů, uoou.gov.cz.

Consumer disputes

If you are a consumer and we cannot settle a complaint between us, you may bring the matter to Česká obchodní inspekce, which is the competent body for out-of-court resolution of consumer disputes in the Czech Republic — adr.coi.cz. We are not bound to, and do not currently participate in, any other alternative dispute resolution scheme.

In practice, writing to us first is faster than either route. We would rather fix the problem than argue about it.
