ULDA License Overview

ULDA is distributed under a dual-license model:

  1. ULDA-NC-1.0 (Non-Commercial License) — for personal, research, or educational use.
  2. ULDA Commercial License — for paid, hosted, or large-scale applications.

If your use case exceeds the limits of Personal Hosting or involves any commercial activity,
please contact admin@0am.ch for a commercial license.

0. Definitions

  • “Software” — the source code, object code, libraries, build scripts, documentation, examples, and any files/packages bearing this license header, including (without limitation) the ULDA Sign library, “ULDA approach” code, and the client SDKs (including the @zeroam/ulda npm package).
  • “Modified Work” — a derivative or collective work based on or including the Software.
  • “Non-Commercial Purpose” — use that (a) is not directed to commercial advantage or monetary compensation, and (b) is not offered as paid or large-scale hosting/service to third parties.
  • “Commercial Use” — any use by or for an organization (including internal use), integration into a paid product/service, hosting beyond Personal Hosting limits, or monetization (including advertising, sponsorships, or donations tied to hosting or functionality).
  • “Personal Hosting” — non-commercial demo/educational hosting subject to both aggregate limits: fewer than 1,000 unique external users per month and fewer than 25,000 requests per month, with no fees, ads, sponsorships, or donations connected to such hosting. Exceeding either limit constitutes Commercial Use.

  3. Anti-Circumvention — Sharding, multi-accounts, multiple deployments, or proxies to bypass limits are forbidden; load is aggregated across all related instances.
  4. No commercial look-alikes — You may not commercially use a work reproducing the Software’s functionality or interfaces if based on or adapted from the Software.
  5. License continuity — You may not change or relicense ULDA code. Modified Works must retain this license for all ULDA components.
