NikPak - END USER LICENCE AGREEMENT (EULA) ========================================== NikPak (c) 2026 Nicolas Choukroun. All rights reserved. Distributed and licensed by Nikkoid LLC ("Nikkoid"). Web site and licences: https://nikpak.nikkoid.com/buy.php NikPak is distributed as SHAREWARE. By installing, copying or using NikPak you accept this licence. If you do not accept it, delete NikPak. 1. OWNERSHIP NikPak (the program nikpak and nikpak.exe, its graphical interface, its documentation and the .nik archive format specification) is the property of Nicolas Choukroun and is distributed and licensed by Nikkoid LLC. You receive a right to use it, not ownership. All rights not expressly granted here are reserved. 2. FREE USE BY INDIVIDUALS A private individual may use the unregistered (evaluation) copy of NikPak free of charge, without time limit, for personal and non-commercial purposes. The program shows a reminder that asks you to register. Registering with a personal licence (USD 19) removes the reminder and supports development. 2a. UNNIK IS FREEWARE unNik (unNik.exe), the archive browser and extractor included in the NikPak package, is free for everyone - individuals, companies and organisations - with no registration and no time limit. The licence fees in sections 2 to 4 apply to NikPak (nikpak and nikpak.exe), which creates archives, not to unNik. Sections 1 and 5 to 11 also apply to unNik; it may be distributed on its own under the conditions of section 5. 3. USE BY COMPANIES AND ORGANISATIONS Companies, self-employed professionals, public administrations, associations, schools and every other organisation, and any commercial use, need one company licence per seat. Prices per seat (USD): 1-9 seats 19, 10-24 seats 15, 25-49 seats 12, 50-99 seats 9, 100-199 seats 7, 200-499 seats 6, 500 seats and more 5. A seat is one computer on which NikPak is installed or one user who uses it, whichever count is higher. Organisations may evaluate NikPak free of charge for 40 days. After this period they must buy licences or stop using NikPak. 4. REGISTERED VERSION A licence key is issued for a name and an e-mail address and is personal to its holder (the person, or the organisation for a company licence). - Personal licence: the holder may use NikPak on all the computers they personally own or use. - Company licence: the organisation may use NikPak on the number of seats shown in the licence. The licence key must not be published, shared outside its holder, sold or given away. A key that is published may be revoked in future versions. A licence is valid for the version purchased and, unless stated otherwise at purchase, for all later 1.x versions. 5. DISTRIBUTION You may copy and distribute the unregistered evaluation copy freely, for example on shareware and download sites, CD/DVD compilations and magazines, provided that: a) the package is distributed complete and unmodified, with this LICENSE.txt and THIRD-PARTY-NOTICES.txt; b) no licence key, key file (nikpak.key, license.txt), key generator, patch or crack is added to it; c) no fee is charged for NikPak itself (a reasonable fee for the media or the distribution service is allowed); d) NikPak is not presented as your own product, and it is not bundled with software that installs itself without the user's clear consent (adware, toolbars and the like). Nikkoid may withdraw this permission from any distributor. 6. RESTRICTIONS You may not modify, translate, decompile or disassemble NikPak, except where the law expressly allows it despite this restriction (for example to obtain the information needed for interoperability). You may not remove or bypass the registration check or the reminder, or distribute modified copies. 7. YOUR ARCHIVES Archives (.nik files) created with NikPak belong to you. No fee or royalty is due for creating, distributing or selling .nik archives, whether NikPak is registered or not. 8. ENCRYPTION NikPak contains strong encryption (Argon2id, XChaCha20-Poly1305). You are responsible for complying with the export and use laws of your country. A lost password cannot be recovered by Nikkoid or anyone else. 9. NO WARRANTY NikPak is provided "AS IS", without warranty of any kind, express or implied, including fitness for a particular purpose. Keep backups of important data. To the extent permitted by law, Nikkoid is not liable for any loss of data, profit or other damage resulting from the use or the inability to use NikPak. Nothing in this licence limits rights that consumers have under mandatory law. 10. THIRD-PARTY COMPONENTS NikPak contains open-source components (zstd, liblzma, preflate-rs, egui and others) used under their own licences. Their notices are in THIRD-PARTY-NOTICES.txt. Those licences apply to those components only. 11. TERMINATION AND LAW This licence ends automatically if you break its terms; you must then delete every copy of NikPak. This licence is governed by French law. Nikkoid LLC - https://nikpak.nikkoid.com
