Privacy policy.

No accounts or personal submissions

WTF Evals does not ask for your name, email address, or other personal details. There are no accounts, sign-up forms, or message forms. We do not receive or retain the text you enter in the exercise.

What you type in the exercise

The eval exercise processes your entries in your browser. The page loads the bundled example files, then runs the checks locally. Its code does not submit your edited cases or results to a server, store them in a site account, or include them in analytics. You do not need an account to use it.

Copy places the displayed command on your device's clipboard. Downloads save JSON cases or the runnable ZIP kit to your device. Edited cases are not saved by the site when you reload; download them to keep your changes. Your browser or operating system may retain page state, clipboard contents, or downloaded files under its own settings. Please do not enter secrets or confidential personal data.

Hosting and security

Cloudflare delivers this website and helps protect it from abuse. When you request a page, Cloudflare processes connection and request information such as your IP address, the requested URL, and browser information to deliver and secure the service. Security features may use cookies where needed.

Cloudflare's handling of this information is described in its privacy policy. The website does not ask you to supply your name, location, or email to read a guide or use the exercise.

Audience and performance measurement

We use Cloudflare Web Analytics to understand page visits and loading performance. Its reports include aggregate visits, pageviews, referring sites, approximate country, browser and device categories, and performance measurements.

Cloudflare describes this service as cookie-free and says it does not track individuals across websites. The measurement code receives page and performance information; we do not send your edited cases, evaluation results, clipboard contents or downloaded files to it. Learn more in Cloudflare's Web Analytics documentation.

Advertising and cookies

Advertising is not currently active on WTF Evals. The homepage loads Google's consent code to provide regional privacy messages. No ad placements are active, and the site does not request advertising. Choosing a privacy option does not turn advertising on.

Google's consent code can receive information about your browser and visit, store your privacy choices, and detect ad blockers for reporting. The code is not loaded on this privacy page, the exercise, or the other supporting pages.

Use Privacy choices on the homepage to reopen the European consent message where it applies. Where Google's US privacy message applies, use its Do Not Sell or Share My Personal Information link. Available controls depend on your region and Google's message availability. If the controls cannot load, advertising remains disabled.

We are preparing to use Google AdSense. If advertising is activated, Google and other advertising vendors may use cookies or similar technologies to serve and measure ads. Personalized advertising can be based on prior visits to this and other websites. We will update this policy to describe the active configuration before enabling ad requests.

You can learn how Google uses information on partner sites at Google's partner-site privacy explanation, manage Google's personalized advertising at My Ad Center, or review participating vendors' choices at YourAdChoices. These external choices do not replace any consent control required on this site.

Your browser and files

You control the files you download. You can clear your clipboard, delete downloaded files, and manage cookies and site storage through your browser. Clearing site storage does not delete downloaded files.

External links and changes

Linked papers, documentation, and other websites have their own privacy practices. Service providers may process information in different countries under their applicable terms and safeguards.

This policy will be updated when the site's data practices change. The date at the top identifies the latest revision.
