End User License Agreement

END USER LICENSE AGREEMENT (EULA) FOR BRAIN NAS SOFTWARE

Effective Date: February 13, 2026 Last Updated: February 13, 2026

IMPORTANT — READ CAREFULLY BEFORE USING THIS SOFTWARE.

This End User License Agreement ("Agreement" or "EULA") is a legally binding contract between you, the individual or entity installing or using the Software ("User," "you," or "your"), and Wallin Solutions ("Licensor," "we," "us," or "our"), operated by Robert Wallin. As used herein, "Wallin Solutions" refers to the business entity operated by Robert Wallin, whether structured as an enskild firma (sole proprietorship) or aktiebolag (limited company) under Swedish law.

BY INSTALLING, COPYING, OR OTHERWISE USING BRAIN NAS SOFTWARE, YOU ACKNOWLEDGE THAT YOU HAVE READ, UNDERSTOOD, AND AGREE TO BE BOUND BY THE TERMS AND CONDITIONS OF THIS AGREEMENT. IF YOU DO NOT AGREE TO THESE TERMS, DO NOT INSTALL OR USE THE SOFTWARE. UNINSTALL THE SOFTWARE IMMEDIATELY AND, IF APPLICABLE, REQUEST A REFUND WITHIN THE WITHDRAWAL PERIOD DESCRIBED HEREIN.

This Agreement is governed by Swedish law, including but not limited to applicable provisions of the Konsumentköplag (Consumer Sales Act), Lag (2022:260) om digitalt innehåll (Digital Content Act implementing EU Directive 2019/770), and Distansavtalslag (Distance Contracts Act). Where mandatory consumer protection provisions of Swedish or European Union law apply, they shall prevail over conflicting provisions of this Agreement.

1. DEFINITIONS

1.1 "Software" means the Brain NAS operating system software, including all associated files, libraries, modules, scripts, firmware, documentation, and any Updates provided by the Licensor.

1.2 "License Key" means the unique alphanumeric code provided by the Licensor that activates the Software for a specific License Tier.

1.3 "Hardware ID" or "HWID" means the unique hardware fingerprint derived from the physical USB storage device on which the Software is installed.

1.4 "License Tier" means the specific level of functionality granted to the User, as defined in Section 3.

10. UPDATES AND MODIFICATIONS

10.1 The Licensor may, at its sole discretion, provide Updates to the Software. The Licensor is under no obligation to develop, release, or deliver any Updates. The availability of Updates does not create any entitlement to future Updates.

10.2 Updates may be delivered automatically through built-in update mechanisms. By using the Software, you consent to the automatic download and installation of Updates. If you do not wish to receive automatic Updates, you may disable this functionality in the Software settings where available, but the Licensor shall not be liable for any issues arising from the use of outdated versions.

10.3 All Updates shall be subject to the terms of this Agreement unless accompanied by a separate or updated agreement.

10.4 The Licensor reserves the right to modify, suspend, or discontinue any feature or functionality of the Software at any time, with or without notice. The Licensor shall not be liable to you or any third party for any modification, suspension, or discontinuation of the Software or any feature thereof.

11. SUPPORT

11.1 The Licensor is under no obligation to provide technical support, maintenance, training, consulting, or any other assistance in connection with the Software.

11.2 Any support that the Licensor may choose to provide is offered voluntarily and may be modified or discontinued at any time without notice or liability. The provision of support in one instance does not create an obligation to provide support in any future instance.

11.3 Community forums, documentation, or other resources that the Licensor may make available are provided for informational purposes only and without any warranty or guarantee of accuracy.

12. TERMINATION

12.1 This Agreement is effective from the date you first install or use the Software and continues until terminated.

12.2 Termination by User. You may terminate this Agreement at any time by uninstalling and ceasing all use of the Software, and by destroying or deleting all copies of the Software in your possession or control.

12.3 Termination by Licensor for Cause. The Licensor may terminate this Agreement if the Licensor has reasonable belief that:

(a) You have materially breached any term or condition of this Agreement and have failed to cure such breach within fourteen (14) days of receiving written notice thereof;

(b) You are using the Software for any unlawful purpose, including but not limited to distribution of illegal content, circumvention of copyright protections, or facilitation of criminal activity;

(c) You have engaged in fraud, misrepresentation, or abuse in connection with the License Key, Hardware ID, or the licensing system;

(d) You have attempted to circumvent, disable, or tamper with any license enforcement, hardware binding, or copy protection mechanism in the Software; or

(e) You have distributed, sublicensed, resold, or made the Software or License Key available to unauthorized third parties.

For the purposes of this Section, "reasonable belief" means that the Licensor has identified facts, circumstances, or technical indicators that would lead a reasonable person to conclude that the specified conduct has occurred. The Licensor is not required to prove the conduct to any particular evidentiary standard before exercising its termination rights under this Section.

12.4 Notice and Cure. Except in cases of fraud (Section 12.3(c)) or license circumvention (Section 12.3(d)), the Licensor shall provide you with written notice specifying the grounds for termination and a fourteen (14) day period to cure the breach. If you cure the breach within this period, the Agreement shall continue in full force and effect. In cases of fraud or license circumvention, termination may take effect immediately upon notice.

12.5 Effects of Termination. Upon termination:

(a) All rights granted to you under this Agreement shall immediately cease;

(b) You shall immediately cease all use of the Software;

(d) Any License Key associated with your license shall be deactivated;

(e) Your User Data remains your property. Before or during the termination notice period, you are responsible for retrieving your User Data from your storage devices. The Licensor has no access to your User Data and cannot assist with data retrieval.

12.6 Refund on Licensor-Initiated Termination. If the Licensor terminates this Agreement under Section 12.3 for any reason other than fraud (12.3(c)) or license circumvention (12.3(d)), you shall be entitled to a pro-rata refund of the license fee paid, calculated based on the time elapsed since purchase relative to a notional five (5) year license period. No refund shall be issued in cases of fraud or license circumvention.

12.7 License Degradation. If the Software has been successfully validated against the Licensor's license server at least once, the license shall remain fully valid regardless of subsequent network connectivity. Network failures alone will never trigger degradation of a previously-validated license; only an explicit server-confirmed revocation (Section 12.3) can deactivate such a license. For licenses that have never been successfully validated online (e.g., a newly activated license on a NAS without internet access), if the Software is unable to contact the Licensor's license server for thirty (30) consecutive days, the Software will temporarily revert to the free tier (2 disk limit). During this degradation period:

(a) All User Data remains accessible and intact on all storage devices;

(b) Data on disks exceeding the free tier limit is accessible in read-only mode — you may read, copy, and back up your data but cannot write new data to those disks;

(c) Full functionality at your purchased License Tier is restored automatically upon a successful license validation check;

(d) This degradation is a temporary technical safeguard against license abuse and does not constitute a termination of this Agreement or a forfeiture of your license rights;

(e) The thirty (30) day grace period is designed to account for temporary server outages, scheduled maintenance, and other interruptions. The Licensor shall not be liable for any degradation of service caused by unavailability of the license validation server, whether due to server downtime, maintenance, cyberattacks on the Licensor's infrastructure, internet outages, DNS failures, or any other cause beyond the Licensor's reasonable control. Such events are also subject to the Force Majeure provisions of Section 16.

12.8 Dissolution of Licensor. In the event that Wallin Solutions ceases to operate as a business entity, is dissolved, enters into bankruptcy or insolvency proceedings, or otherwise permanently discontinues its business activities (a "Dissolution Event"):

(a) The license granted under this Agreement shall automatically convert to a perpetual, irrevocable, royalty-free license to use the Software at the License Tier active at the time of the Dissolution Event. This perpetual license shall be validated solely by the Ed25519 digital signature embedded in the License Key and shall not require any server communication, online validation, or periodic check. The license degradation mechanism described in Section 12.7 shall cease to apply.

(b) All obligations of the Licensor under this Agreement — including but not limited to the obligation to provide Updates, maintain the license validation server, process hardware transfers, or provide any form of support — shall cease permanently and irrevocably upon the Dissolution Event.

(c) No refunds shall be due for licenses purchased prior to the Dissolution Event. The conversion to a perpetual license under Section 12.8(a) constitutes full and final satisfaction of the Licensor's obligations with respect to the license.

(d) Any claims by the User arising under this Agreement must be asserted within six (6) months of the effective date of the Dissolution Event. Claims not asserted within this period shall be deemed waived and forever barred, to the maximum extent permitted by applicable law.

(e) Upon the expiry of the claims period in Section 12.8(d), the User and the Licensor (including its owner(s), whether operating as enskild firma or aktiebolag) shall be mutually and irrevocably released from all obligations, liabilities, and claims arising under or in connection with this Agreement, the Software, or the use thereof.

(f) The Licensor shall use reasonable efforts, prior to or upon a Dissolution Event, to release a Software update that removes the periodic license validation requirement, enabling all licensed installations to continue operating at their purchased License Tier without any server dependency. However, the failure to release such an update shall not affect the validity of the perpetual license granted under Section 12.8(a), which takes effect automatically by operation of this Agreement.

Nothing in this Section 12.8 shall limit the User's rights under mandatory provisions of applicable consumer protection law (including Konsumentköplagen and Lag (2022:260) om digitalt innehåll) or applicable insolvency law.

12.9 Survival. Sections 6, 7, 8, 9, 12.6, 12.8, 14, 15, 16, 17, and 20 shall survive termination of this Agreement.

13. MODIFICATION OF TERMS

13.1 The Licensor reserves the right to modify, amend, or replace this Agreement at any time. Updated terms will be posted on the Licensor's website (brainos.wallinsolutions.se) and may also be communicated through the Software.

13.2 Your continued use of the Software after the posting of modified terms constitutes your acceptance of the modified terms. If you do not agree to the modified terms, your sole remedy is to cease using the Software.

13.3 Material changes to this Agreement will be communicated with at least thirty (30) days' notice before taking effect. Non-material changes may take effect immediately upon posting.

13.4 Where mandatory provisions of applicable law require your affirmative consent to material changes, such provisions shall prevail.

14. GOVERNING LAW AND DISPUTE RESOLUTION

14.1 This Agreement shall be governed by and construed in accordance with the laws of Sweden, without regard to its conflict of law principles.

14.2 Any dispute, controversy, or claim arising out of or in connection with this Agreement, or the breach, termination, or invalidity thereof, shall be subject to the exclusive jurisdiction of Stockholms tingsrätt (Stockholm District Court) as the court of first instance.

14.3 Notwithstanding Section 14.2, if you are a consumer resident in the European Union or European Economic Area, you retain the right to bring proceedings in the courts of your country of residence in accordance with mandatory provisions of applicable law, including Regulation (EU) No 1215/2012 (Brussels I Recast).

14.4 If you are a consumer resident in the European Union, you may also submit disputes to the European Commission's Online Dispute Resolution (ODR) platform at https://ec.europa.eu/consumers/odr/.

14.5 Nothing in this Agreement shall prevent the Licensor from seeking injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property rights.

15. SEVERABILITY

15.1 If any provision of this Agreement is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such provision shall be modified to the minimum extent necessary to make it valid, legal, and enforceable while preserving the original intent of the parties. If such modification is not possible, the provision shall be severed from this Agreement.

15.2 The invalidity or unenforceability of any provision shall not affect the validity or enforceability of the remaining provisions of this Agreement, which shall continue in full force and effect.

15.3 Where a provision is held invalid as to its scope or breadth, it shall remain valid to the maximum scope or breadth permitted by applicable law.

16. FORCE MAJEURE

16.1 The Licensor shall not be liable for any failure or delay in performing its obligations under this Agreement to the extent that such failure or delay is caused by circumstances beyond its reasonable control, including but not limited to: acts of God, natural disasters, epidemics, pandemics, war, terrorism, civil unrest, government actions, sanctions, embargoes, labor disputes, power failures, internet outages, cyberattacks, third-party service provider failures, or failures of telecommunications infrastructure.

16.2 If a force majeure event continues for more than ninety (90) days, either party may terminate this Agreement by written notice to the other party.

17. USER RESPONSIBILITIES

17.1 You are solely responsible for:

(a) Maintaining adequate, independent, and regularly tested backups of all User Data; (b) Ensuring that your hardware meets the minimum requirements for the Software; (c) Maintaining the physical security and integrity of your storage devices and USB boot device; (d) Securing your network, systems, and accounts against unauthorized access; (e) Complying with all applicable laws and regulations in your use of the Software; (f) Evaluating the suitability of the Software for your specific needs and use case; (g) Monitoring disk health, storage capacity, and system status; (h) Maintaining a stable and adequate power supply for all connected hardware, including uninterruptible power supply (UPS) where appropriate.

17.2 The Licensor is not responsible for any damage or loss resulting from your failure to fulfill the responsibilities described in this Section 17.

17.3 Security Configuration Responsibility. The Software provides configurable security settings that you may modify through the Software's user interface. You acknowledge and agree that:

(a) You are solely responsible for any changes you make to the Software's security configuration, including but not limited to firewall rules, encryption settings, grace periods, VPN configuration, SSH access settings, password policies, and any other security-related parameters;

(b) Modifying security settings from their defaults may reduce the protection of your system and User Data against unauthorized access, data loss, or other security threats;

(c) The Licensor provides the Software with secure default settings that reflect best practices for NAS security. Any deviation from these defaults is at your own risk.

17.4 Presumption of User Modification. Where the Software's security configuration at the time of an incident differs from the default configuration as shipped by the Licensor, it shall be presumed that such changes were made by the User or at the User's direction. This presumption may be rebutted by evidence demonstrating that the configuration was altered without the User's knowledge or consent (e.g., through a verified third-party exploit). The burden of providing such evidence rests with the User.

17.5 Mandatory Security Features. The Software incorporates certain security features that are fundamental to its architecture and cannot be disabled, bypassed, or modified by the User. These mandatory features include, but are not limited to:

(a) Network Disconnection Response ("Network Panic"): If the system detects a loss of network connectivity (including disconnection of the Ethernet cable or loss of the network link), the Software will automatically initiate an immediate forced reboot. This causes all LUKS encryption keys held in RAM to be destroyed, rendering all encrypted disks inaccessible until the correct encryption credentials (PIN or password) are provided at next boot. This feature is designed to protect encrypted data in the event of physical theft, unauthorized physical access, or tampering. The reboot is forceful and immediate, and cannot be interrupted, delayed, or prevented once initiated. The grace period before reboot is configurable but defaults to three (3) seconds.

(b) Ephemeral Cache Encryption: Cache drives used for temporary or tiered storage are encrypted using keys that exist only in RAM and are never written to persistent storage. These keys are destroyed on every reboot, rendering all cached data permanently unrecoverable after any shutdown, reboot, or power loss.

(c) Encryption Architecture: Where LUKS full-disk encryption is enabled on data or parity disks, the parity protection system operates on encrypted blocks (ciphertext), not on plaintext data. Parity data therefore contains only encrypted blocks that are unreadable without the corresponding encryption key.

You acknowledge and agree that these mandatory security features are an integral and non-negotiable aspect of the Software's security-first design. The Software is fundamentally designed around the principle that data protection takes precedence over availability. The Licensor shall not be liable for any consequences arising from the normal operation of these mandatory security features, including but not limited to:

(i) Loss of access to encrypted data due to a network disconnection event or any other trigger of the Network Disconnection Response;

(ii) Loss of cached data due to reboot, power loss, shutdown, or the destruction of ephemeral encryption keys;
