# iolinki Commercial License ## Overview This document outlines the commercial licensing options for **iolinki**, an IO-Link Device protocol stack. ## Scope for new quotes The product-family scope below applies to new quotes using version 2026-10-01-product-family-v2. Rights already granted or separately agreed remain governed by their accepted agreement; this scope does not reduce those rights. ## License Tiers ### Single Developer License **Price**: €1,399 (One-time, Royalty-Free) **Includes**: - Full source code access - One agreed, named product family; unlimited manufactured units and customers within that family - 1 year of updates and bug fixes - Email support (48h response time) - License holder: one named individual; one developer seat - Two onboarding hours: build/setup assistance, MCU/PHY wiring and callback review, and a written bring-up checklist - Larger ports quoted separately **Ideal for**: Independent developers, startups, small product lines --- ### Team License **Price**: €4,699 (One-time, Royalty-Free) **Includes**: - The same source code, documentation and reference release as Single Developer - One agreed, named product family; unlimited manufactured units and customers within that family - 1 year of updates and bug fixes - License holder: the named legal company; up to 5 authorized developers - Seats may be reassigned when engineers change - Contractors working on the licensee company's projects count within those 5 authorized developers; subsidiary rights require a separate quote - Priority email support (24h response time) - Quarterly technical reviews - Up to 8 total scoped integration hours (replaces the Single onboarding allowance; not 2 + 8 hours) - Agree the board, compiler, PHY and validation tasks before scheduling; larger ports quoted separately **Ideal for**: Engineering teams, consultancies, mid-size manufacturers --- ### Enterprise License **Price**: Custom (Site-wide, Royalty-Free) **Includes**: - Team source, documentation and support benefits; broader product scope by agreement - Multiple product families, subsidiary rights and broader SDK redistribution by custom quote - Unlimited developer seats (single site) - Dedicated support channel - Custom feature development (negotiable) - On-site training options - Extended warranty and SLA **Ideal for**: OEMs, large manufacturers, multi-product deployments --- ## Product-family scope A product family is the named commercial product range recorded in the agreed quote, including variants, successors and hardware revisions within that range. Manufactured-unit counts, customer counts and variants within the family are unlimited and royalty-free. An unrelated product line needs a separate license. Changing MCU or PHY within the agreed family does not invalidate the license or require a new license; porting and hardware validation are separately scoped and quoted. Enterprise quotes cover multiple families, subsidiaries or broader SDK redistribution as explicitly agreed. ## Package and assistance scope Both tiers receive the same usable source, documentation and reference release. Reference build evidence and remaining validation limits are published separately; included assistance does not promise a completed port, supplied hardware, physical validation or conformity certification. Reproducible product bug corrections do not consume the custom porting assistance allowance. Single is held by the named individual, not by an employer or other legal entity. Employer-project use, transfer rights, upgrade credit, assistance booking windows and any additional renewal coverage must be agreed in the quote. Team is held by the named legal company; subsidiary and other separate-entity rights require a separate quote. ## When do I need this commercial license? iolinki is dual-licensed. You may always use it **free of charge under the GPLv3** (see the LICENSE file) — including in production — **provided you comply with the GPLv3**, i.e. any work you distribute that incorporates iolinki is also licensed under the GPLv3 (source available). A **commercial license is required only if you distribute a closed-source or otherwise proprietary product** that incorporates iolinki and therefore cannot meet the GPLv3 copyleft obligations. It grants the same code under proprietary terms, with no copyleft requirement. ## Purchase Process 1. **Contact**: Email andrii@shylenko.com with your requirements 2. **Quote**: Receive a formal quote within 48 hours 3. **Agreement**: Sign the license agreement 4. **Payment**: One-time payment via wire transfer or invoice 5. **Delivery**: Receive license key and commercial support access ## Frequently Asked Questions **Q: What happens after the 1-year update period?** A: You retain perpetual rights to use the version you licensed.
