License/Framework
DartNative Framework License

The terms you accept when subscribing to the framework. Two headlines: your shipped apps never stop working — if your subscription ends, apps you already shipped stay licensed to run for their users (Continuity for Shipped Applications, Section 2c) — and the Sunset Commitment: if DartNative is ever discontinued, we are obliged — as is any future owner — to release the source publicly.

DARTNATIVE FRAMEWORK LICENSE

1. DEFINITIONS
   "Licensor" means DartNative / Presence Network Inc.
   "Software" means the DartNative framework, including its source code,
   binaries, and tooling, which are the exclusive property of Licensor.
   "Licensee" means the holder of a valid license token obtained through
   https://dartpub.dev.
   "First-Party Plugins" means Licensor's plugins distributed through
   https://dartpub.dev.

2. LICENSE GRANT
   A valid license token grants Licensee a limited, non-exclusive,
   non-transferable, non-sublicensable right to:
   (a) use the Software to build and deploy applications;
   (b) access the Software via the DartNative private package registry while
       the subscription is active; and
   (c) Continuity for Shipped Applications: applications built and
       distributed to end users under a valid subscription remain licensed
       to run for those end users after the subscription expires. Expiry
       ends the rights in (a) and (b); it never ends the right of an
       already-distributed application to keep running. This continuity
       does not apply where the license token is revoked for breach of this
       license or for fraud.

3. RESTRICTIONS
   Licensee may not:
   (a) copy, modify, distribute, sublicense, or create derivative works of
       the Software;
   (b) reverse-engineer, decompile, or disassemble the Software;
   (c) remove or obscure any proprietary notices;
   (d) share license tokens with third parties; or
   (e) develop, build, or deploy applications with the Software after
       subscription expiry or token revocation. This does not limit the
       Continuity for Shipped Applications in Section 2(c).

4. SUNSET COMMITMENT
   4.1 Discontinuation. The Software shall be deemed "Discontinued" upon the
       earlier of: (a) Licensor's formal public announcement that the
       Software has reached end-of-life; or (b) the expiration of a
       continuous period of twelve (12) months during which Licensor has
       published no update to the Software — no fixes, improvements, or new
       features — and has made no public statement of continued maintenance.
   4.2 Source Release. Within ninety (90) days of Discontinuation, Licensor
       shall publish the then-current source code of the Software — together
       with the First-Party Plugins — under the BSD 3-Clause License. This
       obligation does not extend to: (i) third-party components, which
       remain governed by their own licenses; (ii) Licensor's trademarks; or
       (iii) Licensor's license-enforcement infrastructure, credentials, and
       signing keys.
   4.3 Survival; Benefit. This Sunset Commitment is binding upon Licensor
       and its successors and assigns, survives any sale, merger, or other
       transfer of the Software or of Licensor, and is made for the benefit
       of each Licensee holding a valid license at the time of
       Discontinuation, each of whom may rely upon and enforce it.

5. THIRD-PARTY COMPONENTS
   The Software includes open-source components, principally: Zero —
   Licensor's fork of Flutter Zero (https://github.com/knopp/flutter_zero,
   created by Matej Knopp), which patches the Flutter SDK
   (https://github.com/flutter/flutter) — together with the Dart SDK
   (https://github.com/dart-lang/sdk; the Dart VM and runtime are embedded
   in every application binary), Yoga (https://github.com/facebook/yoga),
   FlexLayout (https://github.com/layoutBox/FlexLayout), and Skia
   (https://skia.org). These components are not covered by this license:
   each remains governed by its own license (BSD 3-Clause or MIT), whose
   copyright notices and full terms are reproduced in the accompanying
   THIRD_PARTY_NOTICES file — the authoritative inventory of third-party
   components.

6. WARRANTY DISCLAIMER
   THE SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND. IN NO
   EVENT SHALL THE LICENSOR BE LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER
   LIABILITY ARISING FROM USE OF THE SOFTWARE.

7. GENERAL PROVISIONS
   7.1 Governing Law; Venue. This license is governed by the laws of the
       State of Wyoming, United States, without regard to its
       conflict-of-laws principles. The state and federal courts located in
       Wyoming have exclusive jurisdiction over any dispute arising out of
       or relating to this license, and the parties consent to their
       jurisdiction and venue.
   7.2 Severability. If any provision of this license is held
       unenforceable, the remaining provisions remain in full force, and the
       unenforceable provision shall be reformed to the minimum extent
       necessary to make it enforceable.
   7.3 Successors; Assigns. This license binds and benefits the parties'
       permitted successors and assigns.
