Acceptance of these terms
By accessing or using RunHTML, you confirm that you have read, understood, and agreed to follow these terms. If you do not agree with any part, stop accessing the website or using the relevant features.
Service scope
RunHTML provides online HTML editing, CSS preview, JavaScript testing, code copying, HTML download, and time-limited sharing. Normal previews use a browser-generated Blob URL and open in a new tab. The features available on the current page control the service scope.
Code and shared content
You are responsible for the HTML code you enter, edit, copy, download, or share. Normal editing does not automatically upload code. After you click Share and confirm, the code is sent to the server and stored under a random token for 1 hour. Expired shared content is deleted automatically.
You must have the copyright, authorization, license, or other lawful basis needed to submit your code. Do not use RunHTML to infringe another person’s copyright, trademark, privacy, or other rights.
Prohibited uses
Do not use RunHTML to create, distribute, or promote unlawful, fraudulent, malicious, infringing, harassing, hateful, pornographic, violent, terrorist, self-harm, drug-related, or other non-compliant content. Do not upload malware, use pages for phishing or attacks, exploit vulnerabilities, or bypass security controls.
The sharing feature performs a content-safety review before creating a link. RunHTML may refuse to create a share link, delete shared content, or limit related requests when content fails review, cannot be confirmed as safe, or violates these rules.
Safety review and third-party services
Before a sharing review, the system removes scripts, styles, tags, comments, and other non-page text from the HTML, then submits up to 2,000 characters of page text to a content-safety service. Third-party availability and handling are governed by that provider’s terms and privacy policy.
Results, backups, and availability
Preview results depend on your HTML, browser capabilities, external resources, and device environment. External fonts, scripts, or network requests may be affected by browser security rules, cross-origin restrictions, or third-party availability. Copy or download important code as your own backup.
We work to keep the service stable, but we do not guarantee that the website, previews, sharing, third-party resources, or any feature will remain available, error-free, or fit for a particular purpose.
Changes and termination
We may add, modify, suspend, or discontinue a feature for technical, operational, security, or legal reasons. We may also change code-size limits, sharing duration, review rules, or page notices. You may stop using RunHTML at any time and clear your local browser draft.
Disclaimer and limitation of liability
To the maximum extent permitted by law, RunHTML provides the service as is and makes no promise about the accuracy, completeness, continuous availability, fitness for a particular purpose, or compatibility of code execution results. You decide whether to use preview and sharing results based on your own risk assessment.
We are not responsible beyond what applicable law requires for code loss, execution failure, interrupted sharing, or indirect loss caused by networks, browsers, devices, code, external resources, user actions, or unforeseeable events.
Updates and contact
We may update these terms as the service or applicable laws change. Continued use of RunHTML after updated content is published means that you accept the revised terms. If you have questions about the service scope, code handling, or these terms, contact us:
