Legal notice.
Who provides this service, how to reach a person, where it runs, and which law applies. Last updated 2026-09-13. Questions go to hello@kehai.io.
01
Who provides this service
Polish law requires the provider of a service supplied by electronic means to be identifiable directly and permanently, which is what this page is for.
The provider is a natural person conducting business activity. Polish law requires that person's name to appear here, which is why it does.
02
Reaching a person
Three addresses, all reaching the operator directly. They exist so a message arrives sorted rather than so it arrives somewhere else.
Nothing is lost by choosing the wrong one. We aim to reply within one business day. This is a target for the first human reply, not a guaranteed response or resolution deadline. Business hours are Monday to Friday, 9:00 to 17:00 Europe/Warsaw (CET/CEST), excluding Polish public holidays. Human email support is included on every plan. The Terms of Use describe support, including any separate written offer for Operator.
03
Where the service is hosted
The complete list of companies that can reach data while the service runs is on the sub-processors page.
04
Supervision and disputes
Polish law governs the agreement. The Terms of Use name the competent courts of Warsaw for disputes, subject to mandatory jurisdiction and consumer protection rules.
There is no online dispute resolution platform link on this page, which is deliberate: the European Commission's platform closed in July 2025 and pointing at it would send somebody to a door that no longer opens.
05
Copyright
The software, the written material, and the design of this site belong to the provider. The measurements a customer collects belong to that customer, and the Terms of Use say so in the clause that survives the agreement ending.
