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 Community, the free-of-charge tier of the Avalonia developer tooling, comprising a subset of Avalonia's development tools designated by Avalonia UI as "essential features." Avalonia Community does not include the complete tooling feature set available in Avalonia Plus, the UI Components available in Avalonia Pro, or any of the support services included in Avalonia Enterprise.

"Commercial Use" means any use of the Software to develop commercial products (products distributed or made available for a fee, or used as part of the Customer's business activity) or to provide paid services. Creation of audiovisual content, where the use of the Software is only demonstrated by the Customer for educational or other non-commercial purposes, is not considered Commercial Use, even if the content itself is made available for a fee or profit.

"Non-Commercial Use" means any use that does not fall under the definition of Commercial Use.

2. Customer Eligibility

2.1 Individuals Only

The Avalonia Community licence is available only to natural persons. The Customer must be at least 13 years old and must not be a corporation, company, partnership, association, or other entity or organisation. An organisation may not obtain, fund, or direct the use of an Avalonia Community licence on behalf of its employees, contractors, or any other individuals.

2.2 Ongoing Eligibility

The Customer must continue to meet the eligibility criteria throughout the term of this licence. If the Customer ceases to qualify (for example, by using the Software for Commercial Use or by allowing an organisation to fund or direct their use), the Customer must either upgrade to a paid licence tier or cease all use of the Software.

3. Licence Grant

3.1 Grant of Community Licence

Subject to the Customer meeting and continuing to meet the eligibility criteria in Section 2, and subject to compliance with the restrictions in this Schedule and the Master Terms, Avalonia UI grants to the Customer free of charge 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 of the licence. Concurrent use by more than one individual is prohibited.

3.2 Non-Commercial Use Only

The licence granted under this Schedule is limited to Non-Commercial Use. The Customer shall not use the Software in a manner that would constitute Commercial Use. This is the trade-off for the licence being provided free of charge.

3.3 Essential Tooling Only

The Community licence covers a subset of Avalonia's developer tooling designated by Avalonia UI as "essential features." It does not include the complete tooling feature set (available in Avalonia Plus and above) or any UI Components (available in Avalonia Pro and above). Avalonia UI may, in its sole discretion, modify the features designated as essential from time to time.

3.4 No Perpetual Rights

The Community licence does not confer any perpetual rights. Upon expiry or termination of the Subscription Period, the Customer's right to use the Software ceases. There are no fallback version rights.

4. Subscription Period and Renewal

4.1 Subscription Period

The licence is granted for a period of one (1) year from the date of activation. The Software will cease to function at the end of the Subscription Period unless renewed.

4.2 Manual Renewal

Renewal is not automatic. The Customer must submit a renewal request through their Avalonia Account at least fourteen (14) days prior to the end of the current Subscription Period. Avalonia UI reserves the right to decline renewal at its sole discretion.

4.3 No Vested Rights

The Customer acknowledges that the Community licence is provided as a goodwill offering and that Avalonia UI may modify or discontinue the Community programme at any time with reasonable notice. The Customer has no vested right to continued free access.

5. Activation and Access

5.1 Avalonia Account Required

The Customer must create and maintain an Avalonia Account to activate and access the Software. There are no offline activation codes or offline licence keys available for the Community tier.

5.2 Periodic Verification

The Software will periodically connect to Avalonia UI's servers to verify the Customer's right to use the Software and to confirm compliance with the terms of this Schedule. An active internet connection is required for continued use.

6. Data Collection and Compliance Monitoring

6.1 Mandatory Telemetry

As a condition of the Community licence, the Customer agrees that the Software will collect and transmit telemetry data to Avalonia UI in its default mode, including usage data and detailed interaction data. This telemetry is used to understand usage patterns, improve the Software, and verify compliance with the Community licence restrictions.

6.2 No Opt-Out

Unlike paid licence tiers, the Community licence does not include the option to disable telemetry. The Customer acknowledges and accepts this as a condition of the free-of-charge licence.

6.3 Compliance Monitoring

Avalonia UI uses automated systems to monitor compliance with the use restrictions set out in Section 3 of this Schedule. Any compliance issues detected by automated systems are reviewed by a person before any action is taken against the Customer's account.

6.4 Data Scope

Avalonia UI does not collect source code, application code, or proprietary business data through telemetry. For full details on data collection and processing, refer to Avalonia UI's Privacy Policy at https://avaloniaui.net/legal-center/privacy-policy.

7. Support

7.1 Community Forum Only

Support is provided solely via the Avalonia community channels on a best-efforts basis with no response time commitments. The Community tier does not include email support, Customer Portal support, or any form of priority issue handling.

8. Additional Restrictions

In addition to the restrictions in Section 4 of the Master Terms:

The Customer shall not share their Avalonia Account credentials or any activation data with any other person.

8.2 Termination for Suspected Misuse

If Avalonia UI reasonably believes that (a) the Customer's use of the Software is unauthorised or fraudulent, (b) information provided by the Customer in connection with this Schedule is incomplete, inaccurate, or unverifiable, or (c) the Customer has breached Section 3 (Licence Grant) or Section 6 (Data Collection and Compliance Monitoring), Avalonia UI may terminate this licence on seven (7) days' written notice to the Customer. During this notice period, Avalonia UI may immediately suspend the Customer's access to the Software. The Customer may object to the termination in writing during the notice period and must provide any information Avalonia UI reasonably requests.

9. Unauthorised Use by Organisations

9.1 Prohibited Organisational Use

The Community licence is not available to organisations, and no organisation may procure, direct, fund, reimburse, or otherwise facilitate the use of one or more Community licences by its employees, contractors, or agents in lieu of purchasing the appropriate paid licence tier. Any such use constitutes a material breach of this Agreement.

9.2 Deemed Organisational Use

Use of the Software shall be deemed to be on behalf of an organisation if any of the following conditions are met, regardless of whether the organisation formally authorised, directed, or had knowledge of the use:

(a) the Software is installed on, or accessed from, equipment owned, leased, or provided by the organisation;

(b) the Software is used over a network owned or operated by the organisation;

(c) the Software is used to develop, debug, test, build, or package an application or component that is owned by, commissioned by, or performed for the benefit of the organisation; or

(d) the individual using the Software is, at the time of use, an employee, contractor, or agent of the organisation and the use occurs in the course of that individual's duties or engagement with the organisation.

The organisation may rebut this presumption only by demonstrating, with clear and convincing evidence, that it had an effective policy in place prohibiting the use of Community-licensed software, that the policy was actively enforced, and that the individual acted in direct contravention of that policy without the knowledge of management.

9.3 Vicarious Liability

An organisation is liable under this Section 9 for the acts and omissions of its employees, contractors, and agents performed in the course of their duties or engagement, whether or not the organisation specifically authorised or had knowledge of those acts or omissions.

9.4 Liquidated Damages

If Avalonia UI determines that an organisation has used, or directed the use of, Community licences in breach of this Section 9 (whether directly under Section 9.1 or by operation of Section 9.2), that organisation shall pay to Avalonia UI, as liquidated damages and not as a penalty, an amount equal to:

(a) the Avalonia Enterprise per-Named-User list price in effect at the time the breach is discovered, multiplied by the number of individuals who used the Software under Community licences on behalf of the organisation, multiplied by the number of twelve-month periods (or part thereof) during which the unauthorised use occurred; plus

(b) a surcharge of 200% of the amount calculated under paragraph (a).

The parties agree that this amount represents a genuine pre-estimate of the loss that Avalonia UI would suffer as a result of such unauthorised use, taking into account the difficulty of detecting such breaches, the administrative costs of enforcement, and the broader harm to Avalonia UI's licensing model. The liquidated damages are payable in addition to, and not in substitution for, any other rights or remedies available to Avalonia UI under this Agreement or at law.

9.5 Audit and Cooperation

Where Avalonia UI reasonably suspects that an organisation is using, or has used, Community licences in breach of this Section 9, Avalonia UI may require the organisation and any individuals involved to cooperate with a compliance investigation, including providing records of use, employment or engagement status, and the identity of the organisation on whose behalf the Software was used. Failure to cooperate shall entitle Avalonia UI to estimate the scope of the breach based on available information.

10. Liability Cap Override

Notwithstanding Section 7.2 of the Master Terms, Avalonia UI's total cumulative liability for all claims arising under or relating to this Schedule shall not exceed one Euro (€1). For the avoidance of doubt, this cap applies only to Avalonia UI's liability to the Customer and does not limit the Customer's or any organisation's liability under Section 9 (Unauthorised Use by Organisations).
