You may use the WAVE Accessibility Tool online web service or browser extensions to help you determine the accessibility of web content. You must first obtain WebAIM's permission if you want to sell WAVE reports or data (e.g. number of WAVE errors, error listings, etc.) derived directly from WAVE, or if you want to modify, copy, license, or create derivative works from WAVE. Furthermore, you may not use WAVE in any manner that could damage, disable, overburden, or impair WAVE reporting services. In other words, excluding API usage, you may not use WAVE in an automated manner or author web spiders or bots that will send URLs or code to WAVE for processing, or automatically save WAVE reports without permission. Additionally, inappropriate content may be flagged and blacklisted from WAVE. WAVE use is closely monitored and abuse will result in permanent IP or content blocking.
This service is being provided "as is", without any express or implied warranty.

Additionally, WebAIM does not guarantee that use of this service will ensure the accessibility of your web content or that your web content will comply with any specific web accessibility standard or law. You understand and agree that you download and/or use the WAVE service and/or browser extensions at your own discretion and risk and that you will be solely responsible for any damages to your computer system or loss of data that results from the download or use of WAVE.

The WAVE server stores certain non-identifying information about users and WAVE online service reports. URLs submitted to the WAVE server are stored and available only to WebAIM staff. Files and code uploaded to the WAVE server are temporarily stored. Cookies are used to track distinct user sessions, maintain user history, and generally improve the WAVE experience. WAVE functions with client cookies disabled, but clients with cookies disabled are limited in the number of WAVE reports they can process. Information about files, URLs, or any other information regarding individual WAVE reports will never be sold, distributed, or made publicly available. When using the WAVE browser extensions, no information about WAVE reports or the content evaluated is sent to WebAIM. If you are at all concerned about security or privacy, the WAVE browser extensions provide a secure and private method for evaluating your web content.
