DARTASTIC PRO SOFTWARE LICENSE AGREEMENT

Effective: 20 May 2026

Licensor: Dartastic.io ("Dartastic", "Licensor", "we", "us"). Licensee: the individual or legal entity that has been granted access to the Dartastic Pro private package registry ("Licensee", "you"). Software: the Dartastic Pro Dart/Flutter library packages — including the Dartastic Pro native runtime engine — distributed via https://pub.dartastic.io, together with any documentation, configuration, data files, build artifacts, and updates Licensor makes available with them (the "Software").

By downloading, installing, depending on, or otherwise using the Software, you agree to this Agreement. If you are using the Software on behalf of an organization, you represent that you have authority to bind that organization, and "Licensee" includes that organization.

GRANT OF LICENSE

Subject to Licensee's continued compliance with this Agreement and payment of applicable fees, Licensor grants Licensee a non-exclusive, non-transferable, non-sublicensable, revocable license, during the subscription term, to:

(a) download and install the Software solely from the Dartastic Pro private package registry at https://pub.dartastic.io; (b) use the Software, in source or compiled form, internally within Licensee's organization; (c) embed the Software (in compiled or obfuscated form) into Licensee's own applications and distribute those applications to Licensee's end users, provided Licensee complies with Section 3 (Restrictions).

The Software is licensed, not sold. Licensor retains all right, title, and interest in and to the Software, including all intellectual property rights. No rights are granted by implication, estoppel, or otherwise except as expressly stated here.

SCOPE OF USE; TIERS AND CAPABILITIES

Licensee's use of the Software is limited to the seat count, tier, quotas, and other quantities specified in Licensee's active subscription, order form, or self-service checkout with Licensor (the "Order").

The Software is delivered in tier- and build-flavor-specific configurations. Features, runtime capabilities, and included services (for example, the native runtime engine, on-device PII scrubbing, crash deobfuscation, ANR and jank attribution, native-heap visibility, and Symbolizer quotas) vary by tier, build flavor, platform, and runtime configuration, as described on https://dartastic.io/pricing and in the applicable product documentation. Nothing in this Agreement guarantees that any particular feature or service is present in, or enabled for, the build delivered to Licensee. Capabilities not included in Licensee's tier are not licensed to Licensee.

RESTRICTIONS

Except as expressly permitted in Section 1, Licensee shall NOT, and shall not permit any third party to:

(a) copy, modify, fork, port, translate, or create derivative works from the Software except to the extent strictly necessary to use the Software as licensed; (b) sublicense, sell, rent, lease, lend, distribute, publish, or otherwise make the source code of the Software available to any third party, including by posting any portion of the source to a public repository, package registry, gist, paste service, model weights, or training corpus; (c) remove, alter, or obscure any copyright, trademark, license-enforcement, or other proprietary notice contained in or on the Software; (d) reverse engineer, disassemble, decompile, or otherwise attempt to derive the source code, internal design, or trade secrets of the Software — including the native runtime engine — except to the extent applicable law prohibits this restriction and Licensee has first given Licensor written notice and a reasonable opportunity to provide the interoperability information itself; (e) use the Software, or any benchmark, performance, or feature data derived from it, to design, develop, train, evaluate, market, or improve a product or service that competes with the Software or with any Dartastic offering; (f) conduct competitive benchmarking, scraping, or automated extraction of the Software, the Dartastic Pro registry, the Symbolizer, or any related service, or publish the results of any such activity, without Licensor's prior written consent; (g) bypass or attempt to bypass any authentication, license-verification, locked-binary, rate-limit, tenant-isolation, or telemetry mechanism in the Software or in the Dartastic Pro registry, or use a build provisioned for one tenant in another tenant; (h) use the Software in violation of applicable law, including export-control, sanctions, and privacy law, or in violation of the Dartastic Acceptable Use Policy.

OWNERSHIP, TRADE SECRETS, AND FEEDBACK

The Software is proprietary to Licensor. Licensee acquires no rights in the Software other than the limited license granted in Section 1.

The native runtime engine, its source code, its build configuration, and its internal algorithms constitute trade secrets of Licensor that derive independent economic value from not being generally known. Licensee acknowledges that unauthorized disclosure or use would cause irreparable harm for which monetary damages are inadequate, and that Licensor is entitled to seek injunctive relief in addition to any other remedy.

If Licensee provides Licensor with suggestions, bug reports, or other feedback ("Feedback"), Licensee grants Licensor a perpetual, irrevocable, royalty-free, worldwide license to use that Feedback for any purpose without obligation to Licensee.

CONFIDENTIALITY

The unobfuscated source code of the Software and any non-public documentation provided with it ("Confidential Information") is the confidential and trade-secret information of Licensor. Licensee shall:

(a) use Confidential Information only as needed to exercise the rights granted in Section 1; (b) protect Confidential Information with at least the same degree of care it uses for its own confidential information, and in no event less than reasonable care; (c) restrict access to Confidential Information to employees and contractors who need it to perform their duties and who are bound by written confidentiality obligations at least as protective as this Section.

The obligations in this Section survive termination for five (5) years; provided that, with respect to information that qualifies as a trade secret, the obligations continue for as long as the information remains a trade secret under applicable law.

FEES AND TERM

Licensee shall pay all subscription fees specified in the Order. Fees are non-refundable except as expressly stated in the Order or the Dartastic Terms of Service. Failure to pay terminates the license under Section 8.

The license term begins on the Effective Date of the Order and continues for the subscription period purchased, renewing automatically unless either party cancels per the renewal terms in the Order.

UPDATES AND SUPPORT

Licensor may, but is not required to, provide updates, upgrades, bug fixes, and new versions of the Software during the term. Support, if any, is provided per the support level specified in Licensee's subscription and the Dartastic Service Level Agreement.

TERMINATION

Either party may terminate this Agreement on written notice if the other party materially breaches it and does not cure the breach within thirty (30) days of receiving notice. Licensor may also terminate immediately, without cure, if Licensee:

(a) fails to pay any fee when due; (b) breaches Section 3 (Restrictions) or Section 5 (Confidentiality); (c) becomes insolvent, files for bankruptcy, or assigns assets for the benefit of creditors; or (d) commences, or assists a third party in commencing, any patent or other intellectual- property claim against Licensor or its products alleging that the Software infringes that party's rights (patent-retaliation termination).

On termination, Licensee shall immediately stop using the Software, remove it from all Licensee systems and applications, and destroy or return all copies of Confidential Information. Sections 3, 4, 5, 9, 10, 11, 12, and 13 survive termination.

DISCLAIMER OF WARRANTIES

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, OR NON-INFRINGEMENT. LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT ANY PARTICULAR FEATURE (INCLUDING PII SCRUBBING OR CRASH DEOBFUSCATION) WILL DETECT OR HANDLE EVERY CASE. LICENSEE IS RESPONSIBLE FOR ITS OWN LEGAL AND REGULATORY COMPLIANCE.

LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL LICENSOR'S TOTAL LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT EXCEED THE FEES PAID BY LICENSEE TO LICENSOR IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE LIABILITY. LICENSOR WILL NOT BE LIABLE FOR ANY LOST PROFITS, LOST REVENUE, LOST DATA, LOSS OF GOODWILL, OR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES, EVEN IF LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THESE LIMITATIONS APPLY REGARDLESS OF THE THEORY OF LIABILITY AND ARE A FUNDAMENTAL BASIS OF THE BARGAIN.

INDEMNIFICATION BY LICENSEE

Licensee will defend, indemnify, and hold harmless Licensor and its members, officers, and agents from and against any third-party claim, and any resulting loss, arising out of (a) Licensee's applications or products, (b) Licensee's data or end-user content, (c) Licensee's use of the Software in violation of this Agreement or applicable law, or (d) Licensee's combination of the Software with other products or services not provided by Licensor.

DISPUTE RESOLUTION; ARBITRATION; CLASS WAIVER

The parties will first attempt in good faith to resolve any dispute through informal negotiation, and then through non-binding mediation, within thirty (30) days of written notice of the dispute. Any dispute not resolved through mediation shall be finally resolved by binding arbitration administered under the Commercial Arbitration Rules of a recognized arbitral body, seated in Sheridan County, Wyoming, before a single arbitrator, in English. Judgment on the award may be entered in any court of competent jurisdiction.

EACH PARTY WAIVES ANY RIGHT TO PARTICIPATE IN A CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION. Either party may seek injunctive or other equitable relief in the state or federal courts located in Sheridan County, Wyoming for actual or threatened infringement or misuse of intellectual property or Confidential Information, and each party consents to the personal jurisdiction of those courts for that purpose. In any proceeding to enforce this Agreement, the prevailing party is entitled to recover its reasonable attorneys' fees and costs.

GOVERNING LAW AND VENUE

This Agreement is governed by the laws of the State of Wyoming, without regard to its conflict-of-laws principles, and excluding the U.N. Convention on Contracts for the International Sale of Goods. Subject to Section 12, exclusive venue lies in the state and federal courts located in Sheridan County, Wyoming.

GENERAL

This Agreement is the entire agreement between the parties about the Software and supersedes all prior or contemporaneous agreements. Failure to enforce any provision is not a waiver. If any provision is held unenforceable, the remainder remains in effect. Licensee may not assign this Agreement without Licensor's prior written consent; Licensor may assign freely, including in connection with a merger, acquisition, or sale of assets. Notices must be in writing to the email or address listed in Licensee's subscription record or, for Licensor, to legal@dartastic.io.
