PLIRO END USER LICENSE AGREEMENT Version 1.0 - 16 September 2026; applies on express acceptance for its stated scope PLEASE READ THIS AGREEMENT. IT EXPLAINS WHAT YOU MAY DO WITH PLIRO, INCLUDING THE UNUSUALLY FRIENDLY PERMISSION TO SHARE THE FREE LEARNER EDITION. This End User License Agreement ("Agreement") is between you and Logicos, a sole proprietorship also trading as Logicos Software, registered with the Dutch Chamber of Commerce under number 97161705 ("Logicos", "we", "us", or "our"). You accept this version when you expressly agree to it for a new licence, order, trial or additional rights identified in the offer. The date alone, installing an update or receiving this file does not replace an earlier accepted agreement. Existing grants, including commercial permissions and updates covered by an earlier agreement, are preserved. Acceptance for new rights does not require surrendering those grants. Keep the earlier agreement and licence records. If you cannot legally accept, a parent, guardian or other person with the necessary legal authority must do so for you. A teacher's role alone does not establish that authority. 1. WHAT THIS AGREEMENT COVERS "Pliro" or the "Software" means the Pliro IDE, command-line tools, compiler, interpreter, bundled runtime and libraries, examples, documentation, and updates supplied by Logicos. "Learner" means the Pliro learning edition made available without a purchase. Free means no licence fee; it does not mean that copyrights, trademarks, security controls, or this Agreement disappear in a puff of smoke. "Paid Features" means Classroom, Creator Pro, or other functionality supplied under a paid order, subscription, or entitlement. "Project Content" means source code, text, artwork, sounds, data, and other material that you or your learners create or import into Pliro. "Generated Application" means an application or executable produced from Project Content using Pliro. 2. YOUR RIGHT TO USE PLIRO Subject to this Agreement and preserved earlier grants, Logicos gives you a limited, non-exclusive, worldwide, non-transferable licence to install and use Pliro on devices you own or control within your valid entitlements and limits. Learner permits learning, personal and noncommercial creation and sharing. Learner is free and has no scheduled trial expiry. Supported native exports for the host operating-system family and explicit Raspberry Pi targets are included with mandatory Pliro branding. Other supported cross-OS targets need Creator Pro. CPU, runtime and toolchain support remain separate requirements. A Pro trial permits noncommercial evaluation of the available Pro tools and supported targets during the stated server-authoritative trial period. Trial exports always retain Pliro branding. A trial requires no payment card and does not automatically become a paid subscription. Trial activation and its deadline must be explicitly shown; installing this software does not start a trial. Only an active paid Creator Pro licence grants new commercial use of Pliro under this version. Commercial use includes client work, creating or maintaining business/internal applications, and authoring for sales, advertising revenue or other monetized distribution. Paid Pro may remove Pliro product branding through supported export options. Never remove required third-party notices. Availability of Pro tools alone, including a trial, is not evidence of a paid licence. Classroom permits its authorised teaching and institutional workflows, including paid teaching. Educational use is distinct from commercial application authoring; Classroom alone does not grant Pro, unbranded exports or commercial app development. A teacher's Pro licence does not extend to every learner. Institutions need the appropriate licences for people using the tools. You may make reasonable backups and deploy the official software within these limits and Section 3. The matching version 1.0 Learner agreement controls the free Learner scope where it replaces this general agreement. The version 1.0 Pro trial and paid Creator Pro supplements explain their respective scope. Future features and unsupported platforms are not promised by these terms. 3. PLEASE SHARE LEARNER You may copy and redistribute the official Learner installer to anyone, anywhere, provided every copy is complete, unmodified, digitally signed by Logicos, and supplied free of any licence or access charge. Put it on a school network, a library server, a classroom image, or a USB stick with a heroic educational destiny. Send it to friends, family, pupils, clubs, and that one cousin who keeps asking what a variable is. Please do. Computers do not learn programming by staring at each other. Yes, this licence really says so. When redistributing Learner, you must: a. include this Agreement and all copyright and third-party notices; b. keep the original Logicos digital signature intact; c. make clear that Pliro comes from Logicos and that you are not Logicos; d. not charge for the Software, a Learner entitlement, or an activation key; e. not add advertising, tracking, malware, unwanted software, or misleading claims; and f. not claim that Paid Features, support, certification, or an affiliation with Logicos is included unless Logicos agreed to it in writing. You may wrap the unmodified installer in an internal school or organisation deployment package if the original installer and signature remain intact and the package is not publicly offered as a modified Pliro product. Public mirrors should carry the original signed installer. Logicos may ask a redistributor to remove an obsolete or unsafe version when a security update is available. This permission covers only the official Learner installer. It grants no source code rights, trademark ownership, Paid Features, licence keys, or permission to distribute altered Pliro binaries. 4. YOUR PROJECTS BELONG TO YOU As between you and Logicos, you retain all rights in your Project Content. Pliro does not acquire ownership because you edit, run, save, or build your work with it. You are responsible for rights to material you import and for how you use or publish your project. You may use, copy, modify and share your Project Content. Use of Pliro itself for authoring or rebuilding remains subject to Section 2. Applications lawfully made under paid Pro for commercial distribution may be sold and otherwise distributed without royalties to Logicos, including after that paid term ends. Learner and trial output may be shared only for the noncommercial purposes allowed by their applicable agreement, unless preserved earlier grants apply. To commercially release work evaluated in a trial, obtain paid Pro and rebuild under that paid licence before release. A later purchase does not retrospectively make trial authoring paid or remove branding from an existing binary. Logicos grants the runtime redistribution rights necessary for these permitted applications. Generated Applications have no Pliro product-licence check, do not require their users to buy or activate Pliro, and continue running independently of the author's later subscription. Runtime independence does not create a commercial permission that was never granted. Third-party component licences remain applicable. Earlier lawful artifact and distribution rights are preserved. 5. PAID FEATURES AND EXPIRY Paid Features may be used only while the relevant entitlement is valid and within its stated limits. Order terms control prices, billing periods, renewal, and purchased quantities. An order that conflicts with this Agreement controls only the specific commercial term it addresses. When a paid entitlement expires, Pliro may stop paid run, build, deployment, or collaboration actions and return to Learner functionality. Expiry does not transfer ownership of Project Content to Logicos, revoke rights already granted for Generated Applications, or authorise Pliro to damage or encrypt your files. Pliro should keep the documented save, export, and recovery paths available for work already open during a licensing problem. After paid-Pro expiry, further commercial authoring, maintenance or rebuilding with Pliro needs an appropriate active paid licence, except for preserved earlier grants. Existing permitted commercial applications may continue to be used and distributed. After a trial ends, free Learner requires its own valid entitlement; source files remain yours. There is no automatic charge or paid conversion. 6. LICENCE AND SECURITY SERVICES Pliro may contact Logicos services to activate, validate, refresh, deactivate, or recover an entitlement and to check for updates. An entitlement may be bound to a device and may allow bounded offline use. You must not share a private licence key publicly or use one outside its purchased limits. Automatic update checks can be disabled in Pliro settings. Some updates may be important for security or compatibility. Nothing in this Agreement reduces any mandatory right to receive updates or remedies for non-conforming digital content. 7. PRIVACY Pliro processes personal data only as described in the applicable privacy notice. The current Logicos Software Privacy Policy is available at https://logicos.software/privacy, and privacy questions may be sent to privacy@logicos.software. Project Content stays under your control unless you choose a feature that transmits or shares it. Schools and other organisations are responsible for required notices, permissions, supervision, and a lawful basis when using online or Classroom features with learners. A product entitlement is not permission for secret monitoring. Separate data-processing terms may apply where Logicos processes personal data on behalf of an organisation. 8. RESTRICTIONS Except where this Agreement or mandatory law permits it, you must not: a. alter, translate, or distribute modified Software binaries; b. remove or conceal copyright, attribution, licence, or security notices; c. bypass activation, entitlement, safety, sandbox, or capability controls; d. sell, rent, sublicense, publish, or pool licence keys or Paid Features; e. use Pliro or its services to distribute malware, violate another person's rights, unlawfully access systems, or break applicable law; f. interfere with or overload Logicos activation, update, or other services; or g. use Logicos names or logos in a way that suggests endorsement or ownership. You may observe, study, test, back up, correct errors in, or obtain interoperability information from the Software to the extent expressly allowed to a lawful acquirer by mandatory law. This Agreement does not restrict rights that cannot lawfully be restricted, including applicable rights under laws implementing Directive 2009/24/EC. 9. THIRD-PARTY COMPONENTS Pliro includes third-party and open-source components. Their notices and licences are available in the Software's acknowledgements or accompanying files. A third-party licence controls that component where it grants rights or imposes conditions different from this Agreement. This Agreement does not take away rights granted directly by an open-source licence. 10. UPDATES, CHANGES, AND AVAILABILITY Logicos may provide fixes, security updates, and new versions. An update may add, change, or remove features where reasonably necessary, but mandatory consumer rights and rights in your Project Content remain unaffected. Logicos may discontinue future distribution or online services after reasonable notice where practicable. Discontinuation does not invalidate lawfully created Generated Applications or, by itself, revoke the Section 3 permission for an already released Learner installer. A materially changed agreement applies to an existing installation only after it is made available to you and accepted where acceptance is legally required. 11. SUPPORT AND EDUCATIONAL USE No support service or service level is included with Learner unless Logicos states otherwise. Paid support is governed by the relevant order or support terms. Pliro is an educational and software-development tool, not a substitute for appropriate adult supervision, teaching judgement, backups, or testing. Do not use Pliro or a Generated Application as the sole control for medical, emergency, transport, industrial, or other safety-critical equipment where a failure could cause death, personal injury, or serious property or environmental damage. 12. WARRANTIES AND STATUTORY RIGHTS Logicos will provide paid digital content and services in accordance with the applicable order and mandatory conformity, update, and consumer-protection law. Consumers may have statutory remedies when digital content is not supplied or does not conform. Those rights are not limited by this Agreement. Learner is supplied without a separate voluntary commercial warranty and may contain errors. To the maximum extent permitted by law, Logicos disclaims implied warranties that can lawfully be disclaimed. This does not exclude any guarantee, remedy, or liability that applicable law makes mandatory. 13. LIABILITY Nothing in this Agreement excludes or limits liability for fraud, wilful misconduct, death or personal injury caused by negligence where not legally excludable, or any other liability or consumer remedy that cannot lawfully be excluded or limited. For consumers, Logicos' liability is governed by applicable mandatory law. For users acting in trade or business, to the maximum extent permitted by law: (a) neither party is liable for indirect or consequential loss, lost profit, lost revenue, or loss of anticipated savings; and (b) Logicos' aggregate liability relating to Pliro in any twelve-month period is limited to the fees paid for Pliro in that period, or EUR 100 if no fee was paid. These business limitations do not apply where liability cannot legally be limited. Each party must take reasonable steps to limit avoidable loss. You remain responsible for appropriate backups of Project Content. 14. TERMINATION This Agreement continues while you use Pliro. You may end it at any time by uninstalling the Software and stopping its use and redistribution. Logicos may terminate your licence for a material breach not remedied within fourteen days after notice, or immediately for deliberate licence circumvention, malicious distribution, or unlawful use creating material risk. On termination you must stop using and distributing Pliro and remove your copies, except where mandatory law permits retention. Termination affects only the person or organisation in breach. It does not cancel lawful copies already received by others, transfer ownership of Project Content, or revoke distribution rights for Generated Applications created before termination. Sections intended by their nature to survive will survive. 15. GOVERNING LAW AND DISPUTES This Agreement is governed by Dutch law. For consumers, this choice does not remove mandatory protections under the law of their country of residence, and they may bring a claim in any court available under mandatory law. Before formal proceedings, please contact us and allow thirty days to try to resolve the issue informally. This does not shorten a legal limitation period or prevent urgent relief. For business users, the competent courts in the Netherlands have exclusive jurisdiction unless mandatory law requires another forum. 16. GENERAL TERMS This Agreement, applicable order terms, and incorporated third-party licences are the agreement about your use of Pliro. If one provision is unenforceable, it will be limited or removed only as far as necessary; the rest remains in effect. A failure to enforce a provision is not a waiver. You may not assign this Agreement except with Logicos' written consent or where mandatory law permits it. Logicos may assign it as part of a merger, reorganisation, or sale of the Pliro business, provided your rights are not materially reduced. The English and Dutch versions are intended to have the same meaning. If a difference cannot be reconciled, the interpretation that best preserves mandatory consumer rights and the evident purpose of the provision will apply. 17.
