NexaSign
Copyright (c) 2026 NexaStack and NexaSign contributors

This product includes software developed at Documenso, Inc.

NexaSign is a German-focused fork of Documenso (https://github.com/documenso/documenso),
and the majority of the code in this repository originates from that upstream
project. All original Documenso copyrights are retained.

The NexaSign fork adds:

  * German localisation beyond the upstream Lingui translations
  * A public templates hub (Vorlagen/) with 11 German contract templates
  * An AV-Vertrag (GDPR Art. 28) generator (PHP + WeasyPrint)
  * An X-Rechnung / ZUGFeRD (EN 16931) generator with local auto-extraction
  * A GoBD compliance hub with retention-cron, WORM-enforcement and export CLI
  * An independent AGPL re-implementation of the Documenso Enterprise Edition
    package (packages/ee/) — see packages/ee/LICENSE and packages/ee/FEATURES
    for what was replaced and why
  * NexaSign branding (logo, wordmark, colour tokens, meta tags)

All original components retain their upstream licenses:

  * The core Documenso application code is licensed under AGPL-3.0-or-later
    (see LICENSE in this repository root — unchanged from upstream).
  * packages/ee/ in the upstream is licensed under the "Documenso Commercial
    License". In NexaSign it has been REPLACED with an AGPL-3.0-or-later
    re-implementation. No Commercial-licensed code from upstream ships in
    this fork.
  * Third-party dependencies retain their respective licenses; see
    package-lock.json and each dependency for details.

Attribution requirements:

  * AGPL-3.0 Section 5(a) — notices of modification: fulfilled by
    CHANGELOG.nexafile.md.
  * AGPL-3.0 Section 5(b) — preserve "Appropriate Legal Notices" in
    user-interactive code: the footer link in the Remix app
    ("NexaSign — ein Open-Source-Projekt von NexaStack") and the footer
    on the public Vorlagen/GoBD pages point to the project's origin.
  * AGPL-3.0 Section 13 — source offer for network interaction: the
    complete source is available at the NexaFile git repository
    (see README.nexafile.md for the URL).

Documenso branding:

  * "Documenso" is the trademark of Documenso, Inc. NexaSign neither claims
    ownership of nor affiliation with Documenso, Inc.
  * User-facing strings that were previously "Documenso" have been changed
    to "NexaSign" in the normal course of rebranding a fork. Strings and
    files that identify Documenso as the origin/author of the upstream
    code (this NOTICE, README.nexafile.md, CHANGELOG.nexafile.md, meta
    tags, packages/ee/LICENSE) intentionally preserve the "Documenso"
    attribution.
