One Windows machine where go-mapi is installed and authenticated against your Google Workspace tenant. If a person has go-mapi on a desktop and a laptop, that is two seats. Per-user (rather than per-device) licensing is on the v2 backlog.

Standalone: data never leaves your machine. go-mapi is a local bridge; nothing is transmitted to a server we operate.

Managed: choose your data region at signup — EU, US, or Worldwide. The control-plane metadata (config, audit logs, fleet state) is stored in the region you pick. Mail content itself never leaves the user's machine in either tier.

Yes. Managed billing is month-to-month or annual; you can cancel at any renewal point and keep your access until the end of the current period. Pilot customers may have a separate written agreement — see "What does 'pilot' mean for me?" below.

Annual subscriptions are refundable pro-rata for the unused portion if you cancel within the first 30 days. Monthly subscriptions are not refunded for the current month. Pilot terms may differ — pilot customers receive concrete written terms before any payment is taken.

Managed is currently in pilot. Pilot customers work with us directly to shape the product — you get the published price, a direct line to engineering, and influence over the roadmap, in exchange for tolerating early-stage rough edges. Pilot status ends when we exit pilot publicly; current pilot customers transition to standard Managed at their renewal with no price change unless agreed in writing.
