Terms of Use

These Terms of Use (“Terms”) govern your access to and use of the ICU Playground website, applications, and related online tools for ICU MessageFormat, ICU syntax, plural rules, validation, examples, converters, and i18n / l10n workflows (collectively, the “Service”). By using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Description of the Service

The Service provides educational and developer-oriented utilities to experiment with and validate ICU-style messages. Outputs are generated for convenience and learning; you are responsible for verifying correctness before use in production systems, apps, or legal or safety-critical contexts.

2. Eligibility

You must be able to form a binding contract in your jurisdiction. If you use the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

3. Acceptable use

You agree not to:

• Use the Service in violation of any applicable law or regulation.
• Attempt to disrupt, overload, or attack the Service or underlying infrastructure.
• Probe, scan, or test vulnerabilities without authorization.
• Circumvent security, access controls, or usage limits.
• Use automated means to scrape or harvest data in a way that harms the Service or other users.
• Upload or process unlawful, infringing, or malicious content through the tools.
• Misrepresent your identity or affiliation.

4. Accounts

The Service may be offered without registration. If we introduce accounts in the future, additional terms may apply. You are responsible for safeguarding credentials you receive.

5. Intellectual property

The Service, including its design, text, graphics, logos, and original code (excluding third-party libraries), is owned by us or our licensors and protected by intellectual property laws. You receive a limited, non-exclusive, non-transferable license to use the Service for personal or internal business purposes in accordance with these Terms.

You retain rights to content you create using the tools (such as ICU strings you author). You grant us a non-exclusive license to process such content only as needed to operate the Service, unless a feature explicitly states otherwise.

6. Third-party services and open standards

The Service may reference or interoperate with third-party technologies, specifications, or documentation (for example Unicode ICU concepts, browser Intl APIs, or framework file formats). Third parties are not responsible for this Service. Their terms and licenses govern their own products.

7. Advertisements

The Service may display third-party advertisements. Advertisers are responsible for their ads. Your dealings with advertisers are solely between you and the advertiser.

8. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS, OR THAT ICU OUTPUTS, CONVERTED STRINGS, OR VALIDATION RESULTS ARE COMPLETE OR SUITABLE FOR YOUR USE CASE.

9. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE OR OUR AFFILIATES, DIRECTORS, EMPLOYEES, OR SUPPLIERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR BUSINESS OPPORTUNITIES, ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE CLAIM (TYPICALLY ZERO FOR FREE USE) OR (B) ONE HUNDRED U.S. DOLLARS (USD $100).

Some jurisdictions do not allow certain limitations; in those cases, our liability is limited to the fullest extent permitted by law.

10. Indemnification

You will defend, indemnify, and hold harmless us and our affiliates from any claims, damages, losses, and expenses (including reasonable attorneys’ fees) arising from your use of the Service, your content, or your violation of these Terms or applicable law.

11. Suspension and termination

We may suspend or terminate access to the Service at any time, with or without notice, for any reason, including if we believe you violated these Terms or pose a risk to the Service or others.

12. Changes to the Service and Terms

We may modify or discontinue features at any time. We may update these Terms by posting a revised version and updating the “Last updated” date. Your continued use after changes become effective constitutes acceptance. If you do not agree, stop using the Service.

13. Governing law and disputes

These Terms are governed by the laws applicable to the relationship between you and the operator of this Service, excluding conflict-of-law rules where permitted. Disputes will be heard by courts of competent jurisdiction, subject to mandatory consumer protections in your country of residence where they cannot be waived.

14. Miscellaneous

• Entire agreement. These Terms constitute the entire agreement regarding the subject matter and supersede prior understandings.
• Severability. If a provision is unenforceable, the remaining provisions remain in effect.
• No waiver. Failure to enforce a provision is not a waiver.
• Assignment. You may not assign these Terms without our consent. We may assign them in connection with a merger or sale of assets.
