Perennos
Perennos is the name used on this website. Our work is built and maintained in the Cayman Islands. Website and service enquiries: talktome@perennos.com. The website address is perennos.com.
A client's written agreement must identify the actual contracting supplier and its formal notice address. This page does not represent “Perennos” as the registered name of an incorporated company or publish an unverified company number, trade licence number, registered office or regulated-professional status.
Names and artwork
Perennos, Perennos Tempo, UMBRA and n4mu are names used for the respective brands and projects. The Perennos P insignia and wordmark identify Perennos. This notice does not assert that any of these marks is registered, establish their legal proprietor or grant permission to suggest an endorsement.
Third-party names and marks belong to their respective owners. Referring to a compatible product does not mean its owner has sponsored, certified or approved Perennos. Permission to use software does not automatically include permission to use its brand artwork.
Perennos Tempo: current and earlier licences
The reviewed source notice states that, from 6 November 2026, Perennos-authored core files are offered under PolyForm Shield License 1.0.0. It permits use, modification and distribution for permitted purposes, with a restriction on providing competing products as defined in that licence. This is a source-available licence, not an unrestricted open-source licence. Read the full licence before using or redistributing the applicable version.
The notice also states that material published before that change, including release v1.0.0, was offered under Apache License 2.0. Recipients of those copies retain the applicable Apache-2.0 terms. A later website notice does not withdraw permissions already granted for an earlier copy. Always check the licence shipped with the exact version; a package may contain several separately licensed parts.
The current core notice includes:
Required Notice: Copyright 2026 Perennos (https://perennos.com)
Licensor Line of Business: Perennos Tempo, a local AI agent harness with routing, workflows, fleet tools and companion apps (https://perennos.com/tempo)
These are software licence notices, not verification of a corporate registration or a statement that a particular product version is publicly downloadable.
Third-party open-source notices
The reviewed core's NOTICE.md identifies these separate licence obligations:
| Material | Notice to preserve |
|---|---|
| Included Sev inference source | Its upstream MIT licence and copyright notice |
| Bundled Windows CPython runtime and Tcl/Tk components, where that installer includes them | Python Software Foundation and the other upstream notices supplied with the runtime |
| Archivo, Instrument Serif, JetBrains Mono and Bodoni Moda font files included in the apps | Their copyright notices and SIL Open Font License 1.1 texts |
| Included three.js 0.170.0 files | Their MIT licence and copyright notice |
| Other Python and Rust dependencies actually distributed | Each dependency's own licence, copyright and any required notices, for the exact package |
Some model, tokenizer or runtime files are optional downloads rather than bundled material. Their publishers' terms must be checked separately; the Perennos licence does not license someone else's weights, datasets, source, outputs or trademarks. A compatible integration is not proof that its licence permits every use.
This page is a readable summary, not the complete notice bundle for every installer. Each distribution must include the licence and required notice texts applicable to its exact contents. Ask talktome@perennos.com, identifying the version and download, for the relevant bundle. Publishing this page does not mean we have completed a full dependency or redistribution audit.
