Corrections and clarifications published by NYX LIMITED. This compact page does not maintain a second hand-edited transcription of the licence: the exact app-supplied PDF is linked below.

This is the compact legal site. It keeps Nyx AI’s legal documents publicly available alongside the full product site. These are point-in-time app-supplied copies; the dated notices above state the current position, and the document bundled with your installed build governs that build.

This legal page is published at nyxai.uk and, for continuity, at nyxionapp.uk; both addresses serve the same documents, and the latter is kept so existing legal links keep working. The update service at updates.nyxionapp.uk is a separate address and does not move.

The PDF linked here is the exact document supplied with the public app corpus. The version that legally governs your copy is the one included with that version of the application; if versions differ, the in-app version prevails.

Getting Nyx AI, and the scope of this page. This site publishes Nyx AI’s legal documents; the full product site follows. Nyx AI is published on the Microsoft Store, and this website offers no direct download of its own. References in the exact EULA to Setup or portable copies govern a copy obtained outside the Store. The linked Threat Model is the unaltered app copy and carries its own review stamp of v1.5.484 against a current release of v1.5.493; no gate, tier or egress path changed between them, and the Security Policy and Threat Model linked here are point-in-time app-supplied copies. No sandbox is 100%.

Corrections shipped in app version 1.5.493. Wordings that earlier notices on this page flagged have now been corrected in the app and in the documents published here. Prefer-local routing is described as a preference with cloud fallback rather than an egress block, and the nonexistent “local-only” routing mode is gone. Ollama Cloud models are classified as off-device everywhere, including the privacy sanitizer and the model labels. The Threat Model and Security Policy restate two limits a documentation revision had trimmed: one approval for repository-controlled execution covers that workspace for the rest of the session, and a recorded permission whose object Windows reports as absent does not block sandboxed execution. The documents on this page are the staged 1.5.493 versions. Distribution channels can update on different schedules; the copy bundled with your installed build governs that build. Recorded 21 August 2026.

Ollama Cloud classification: corrected in 1.5.493. An earlier notice on this page warned that a supported Ollama Cloud model whose name ends -cloud could be labelled local and skip the model-text sanitizer even though its prompts leave this PC. That is fixed in app version 1.5.493. Both the :cloud and -cloud tag forms now resolve through the same off-device test, so the model is labelled remote and its text is scrubbed before it leaves the machine. Builds earlier than 1.5.493 still carry the old behaviour, so treat every Ollama Cloud option there as off-device. Recorded 21 August 2026.

.nyx/rules.md is not generally unreadable. Brokered file and search tools do not expose that control file, and recognized direct model-authored shell-write forms are refused. A literal shell read or copy-from command can still read it when such a command is allowed, and its rules can be supplied to the model as instructions. This is not an operating-system read-denial guarantee. Recorded 20 August 2026.

Inventory provenance. The third-party and commercial-audit files linked here are the exact versions carried by the locally staged, signed app version 1.5.493 package. The third-party summary also uses older browser wording: Nyx AI first tries a usable installed or cached Chrome, Edge or Chromium engine. Chrome Headless Shell may be downloaded only if none launches, or when you explicitly choose the download action, after approval in a native Windows dialog.
