pyspssio ships the IBM licence, redistribution list, and third-party notices inside its installed distribution, normally under pyspssio/spssio/license/. Those materials are authoritative. They are not relicensed by this repository's Apache-2.0 licence.
OpenStatSpec requires the exact openstatspec-pyspssio release declared in pyproject.toml; it has no alternate SPSS engine. This repository does not vendor or alter the IBM binaries. Anyone who distributes an application bundle containing the installed engine must review and comply with the IBM materials supplied with that engine. In particular, the IBM redistribution conditions require object-code-only distribution as part of the distributor's application, preservation of notices, restrictions on use and onward distribution, and end-user terms that protect IBM at least as much as the IBM agreement. They also include other conditions, including support, indemnity, and trademark restrictions.
Do not remove the pyspssio licence directory or notices from a bundled installation. Do not describe IBM or its trademarks as endorsing OpenStatSpec.
This is a factual third-party notice, not legal advice. A party preparing a binary or application distribution should have its own legal review of the exact LA_en, REDIST, and notices files installed with the selected pyspssio release.
