Schedule 10A: Avalonia Pro Licence (Individual)

Version 1.0, effective as of 26 March 2026

This Product Schedule forms part of and is subject to the Avalonia UI Master Terms and Conditions. Capitalised terms not defined herein have the meanings given in the Master Terms.

1. Product-Specific Definitions

"Software" refers to Avalonia Pro, comprising the complete developer tooling suite (as included in Avalonia Plus) together with the UI Components.

"Tools" refers to the complete developer tools and applications included in Avalonia Pro, identical to those provided in Avalonia Plus.

"Components" refers to the proprietary user interface controls, libraries, and similar software components provided as part of Avalonia Pro for incorporation into Avalonia-based applications. Avalonia UI may add to or remove Components from the Avalonia Pro offering at its sole discretion, subject to Section 3.5 of this Schedule.

"Redistributable Components" means the runtime portions of the Components that may be distributed as part of the Customer's applications in compiled form, specifically: Avalonia UI runtime libraries required for rendering UI controls, and any assemblies explicitly designated as redistributable in the Software documentation.

"Perpetual Version" means the version of the Software to which the Customer has acquired perpetual rights in accordance with Section 5 of this Schedule.

"Offline Licence Key" means a Licence Key that does not require periodic online verification and permits the Customer to use the Perpetual Version without an active internet connection.

"Personal Project" means a software project in which the Customer personally owns the intellectual property rights in the resulting application, and which is not directed by, performed on behalf of, or subject to assignment of intellectual property rights to, the Customer's employer or any other organisation.

2. Customer Eligibility

2.1 Individual Customers Only

This Schedule applies only to Customers who are natural persons. Corporations, companies, partnerships, associations, and other entities or organisations must purchase under Schedule 10B (Avalonia Pro - Organisation).

2.2 Own Funds Restriction

This licence is available only to natural persons who are purchasing a subscription to the Software using their own funds. If a third party pays the subscription fees, or if the Customer expects or receives reimbursement for those fees from any third party, the grant of rights under this Schedule is void.

3. Licence Grant

3.1 Grant of Licence

Subject to payment of all applicable fees and continuous compliance with the Master Terms and this Schedule, Avalonia UI grants to the Customer a non-exclusive, non-transferable licence to install and use the Software on any number of Machines, provided that the Customer remains the sole user. Concurrent use by more than one individual is prohibited.

3.2 Tools: Unrestricted Use

The Customer may use the Tools in connection with their employment or contract work without limitation. There are no restrictions on whether the applications developed using the Tools are for personal, commercial, or employer-directed purposes, provided the Customer complies with the own-funds restriction in Section 2.2.

3.3 Components: Personal Projects Only

The Customer may integrate, use, and distribute the Components only in Personal Projects. The Customer shall not use the Components in any project where the intellectual property in the resulting application is owned by, or will be assigned to, the Customer's employer or any other organisation. If the Customer's employer wishes to use the Components, the employer must purchase an organisation-level licence under Schedule 10B (Avalonia Pro - Organisation) or Schedule 11 (Avalonia Enterprise).

3.4 Redistribution of Components

The Customer may reproduce, embed, and distribute the Redistributable Components as part of the Customer's own Personal Project applications, in executable (compiled) form only, and solely as an integral part of those applications. Distribution is permitted only as part of the application's binary or installation package, not as a standalone product or library. End-users may install and use applications incorporating the Redistributable Components without additional runtime or distribution fees.

3.5 Component Catalogue Changes

Avalonia UI may add new Components to or remove existing Components from the Avalonia Pro offering at its sole discretion. Removal of a Component does not affect the Customer's perpetual rights (if any) to versions of the Software that included that Component, but Avalonia UI has no obligation to continue developing, maintaining, or supporting removed Components.

3.6 No Source Code Access

The Avalonia Pro tier does not include access to the source code of the Components. Source code access to the Components is available only under Schedule 11 (Avalonia Enterprise).

3.7 Perpetual Rights

Perpetual rights are earned in accordance with Section 5 of this Schedule. Once acquired, the perpetual rights apply to the Perpetual Version and survive expiry of the subscription, subject to the termination provisions in the Master Terms.

4. Licence Key Restrictions

The Customer shall not share, lend, transfer, or otherwise make available their Licence Key, Offline Licence Key, or Avalonia Account credentials to any other person. Licence Keys are personal to the Customer and are bound to the Customer's Avalonia Account.

If Avalonia UI reasonably determines that a Licence Key has been shared with an unlicensed individual, Avalonia UI may revoke the Licence Key and terminate this licence in accordance with Section 8.3 of the Master Terms.

5. Subscription and Perpetual Licence Mechanics

5.1 Annual Subscription

If the Customer purchases an annual subscription:

(a) The Customer receives a perpetual, Offline Licence Key for the version of the Software current at the date of purchase, effective immediately upon payment.

(b) During the subscription period, the Customer is entitled to receive Software Updates and may use the most current version of the Software, including any new or updated Components.

(c) Upon expiry of the subscription (if not renewed), the Customer retains perpetual rights to the Perpetual Version (including the Components available at that time) but will no longer receive Software Updates or new Components.

5.2 Monthly Subscription

If the Customer purchases a monthly subscription:

(a) The licence is subscription-based (not perpetual) during the subscription period. If the subscription is cancelled or lapses before the conversion point described below, the Customer's right to use the Software terminates at the end of the then-current billing period.

(b) After twelve (12) consecutive months of uninterrupted paid subscription, the licence converts to a perpetual licence for the version of the Software (including Components) in use at the twelve-month conversion point. At that time, the Customer is entitled to an Offline Licence Key for the Perpetual Version.

(c) "Consecutive months" means twelve billing periods with no gap in payment. Avalonia UI provides a seven (7) day grace period for failed payments before the consecutive count resets.

(d) After conversion, the Customer may continue the monthly subscription to receive ongoing Software Updates and new Components, or cancel and retain perpetual rights to the Perpetual Version only.

5.3 Offline Licence Key

Once the Customer has earned perpetual rights, Avalonia UI will issue an Offline Licence Key. The Offline Licence Key permits use of the Perpetual Version without an active internet connection or Avalonia Account verification.

6. Activation and Access

6.1 Avalonia Account Required

The Customer must create and maintain an Avalonia Account to activate and access the Software. During an active subscription, the Software will periodically connect to Avalonia UI's servers to verify the Customer's subscription status.

6.2 Offline Use

The Offline Licence Key (once issued) permits offline use of the Perpetual Version only. Access to Software Updates, new Components, and the most current version of the Software requires an active subscription and periodic online verification.

7. Support and Updates

7.1 Included Support

During an active subscription, the Customer is entitled to receive Software Updates released by Avalonia UI. Support is provided via the Avalonia community channels on a best-efforts basis with no response time commitments.

7.2 Best-Effort Issue Prioritisation

Avalonia UI will make a best-effort attempt to prioritise GitHub issues logged by Avalonia Pro customers. Priority will only be given to issues that include a reproducible bug report. This is a good-faith commitment only, and Avalonia UI makes no guarantees, warranties, or binding commitments regarding response times, resolution times, or the prioritisation of any specific issue.

7.3 No Support After Lapse

If the subscription lapses and the Customer holds a Perpetual Version, the Customer may continue to use that version but will not receive Software Updates, patches, new Components, support, or issue prioritisation of any kind.

7.4 Product Support Baseline

Support is provided in accordance with Schedule 3 (Product Support), as modified by this Schedule.
