Additional Use Grant:

1. Permitted production use
You may make production use of the Licensed Work:
(a) as an individual for personal purposes, not on behalf of an organization;
(b) for the internal purposes of a nonprofit organization, including a nonprofit
    school, other than a government organization;
(c) for the internal educational and administrative purposes of a
    government-operated public school, including use by its own students and
    staff, or by a government-operated public university for its own purposes
    or to provide a hosted service to anyone as permitted by paragraph 4; or
(d) for the internal purposes of a for-profit organization, including a
    for-profit school, provided that no more than five distinct natural persons
    make production use on its behalf during any rolling 30-day period,
    subject to the grace period below.

Government organizations other than the public schools and universities
described in (c) are not granted production-use permission by this grant.

2. Counting production users
For paragraph 1(d), count all distinct people making production use on behalf
of the organization, including employees and contractors, across all accounts,
installations, and deployments. Use through Excel worksheet functions, notebook
actions, shared accounts, APIs, or other interfaces counts. Count each person
once per organization during a rolling 30-day period; the count is not limited
to simultaneous connections or administrators. People making only
non-production use do not count toward this production-use threshold.

3. Sixty-day grace period
A for-profit organization that first exceeds five production users may
continue its internal production use for 60 consecutive calendar days from
the date it first exceeds that threshold. After that period, it must obtain a
separate commercial license or bring its use within the five-user rolling
30-day limit before continuing production use under this grant. The grace
period is available once per organization; it does not restart when the user
count falls and rises again, on a new installation, or on a new version.
This grace period applies only to exceeding the five-user threshold. It does
not grant permission for otherwise excluded government or hosted-service use.

4. Hosted services
Except for the public-university exception below, this grant does not permit
providing the Licensed Work's functionality as a
hosted service to third parties, whether for a fee or without charge,
regardless of the provider's size, user count, or nonprofit status. Such
production use requires a separate commercial license.
Public-university exception: A government-operated public university may host
and provide the Licensed Work's functionality to anyone, including its own
students and staff, outside individuals, and outside organizations, without a
commercial license and without a user-count limit. Anyone may make production
use through that university-hosted service without a commercial license under
this grant, regardless of their affiliation or organization type. This
exception covers the university's hosting and use through that service; it
does not exempt independently operated deployments of outside organizations.
Other qualifying schools and nonprofit universities may provide access to
their own students and staff for internal educational and administrative
purposes. Their hosting for outside organizations remains subject to the
hosted-service restriction.
Hosting on cloud infrastructure for an organization's own internal use does
not by itself constitute a hosted service to third parties.

5. Scope
These conditions apply only to the additional permission for production use.
They do not restrict non-production evaluation, development, testing, or any
other rights granted by the standard Terms below.

Change Date: For each specific version of the Licensed Work, the fourth
anniversary of its first publicly available distribution under this License.

Change License: MIT License, reproduced in LICENSE-MIT.
