An OpenClaw assistant in your environment
Deployment of a server, communication channel, model and selected capabilities. The proposed solution identifies providers, data flows, regions and operating costs.
Account control
Server and API accounts can be held directly by the client so access and charges remain transparent.
Documented data flows
Before launch, the design identifies what reaches hosting, messaging, model and integration providers.
Extensible workflows
Search, files, reminders and business integrations are added within the agreed scope.
Defined support
Updates, monitoring and response targets belong in a separate service scope.

Frequently asked questions
Where is assistant data processed?
It depends on the configuration. The server can be located in the EU, while messaging, model APIs, search and other integrations must be assessed separately. These flows are documented before launch.
Do model providers use data for training?
Terms differ by provider, product, plan and settings. The solution design therefore identifies approved services, accounts, retention rules and available contractual safeguards.
Do users need technical knowledge?
Day-to-day use can happen through a familiar messaging channel. The client still appoints someone responsible for access, integration approval and security decisions.
What is included in support?
The quotation or service agreement defines its exact scope, response targets, updates and limitations.
