Privacy Policy
Last updated: September 26, 2026
Jev Playground is an independent interactive website. This policy explains what happens when you visit the site or submit text to one of its Jev tools. It does not describe the separate products linked from our explanatory pages.
Using the Jev tools
When you run a tool, the input you submit is sent to Jev Playground's server and then to its configured model provider so the tool can return a result. The primary route uses TypeSafe Direct; a recoverable failure may use Vercel AI Gateway as a fallback. The submitted material can include your text, questions, choices, or other fields shown in that tool. Editing a local display setting does not by itself submit another model request.
Do not submit passwords, API keys, private correspondence, or other sensitive material. The public demos do not require you to provide your own Jev key. Provider-side processing is governed by the applicable TypeSafe privacy policy and, when the fallback is used, Vercel privacy policy.
Site access and security
The site is hosted on Vercel. Requests can involve technical data such as IP address, browser and device information, requested URL, and timestamps. Hosting and security systems use this information to deliver the site, diagnose failures, and apply abuse protection and rate limits. Jev Playground does not provide visitor accounts for these public tools.
Advertising and Google AdSense
If advertising is enabled on Jev Playground, third-party vendors, including Google, may use cookies and similar technologies to serve ads based on your visits to this site or other websites. Google and its partners may use information about those visits to provide personalized ads. Third parties may place or read cookies in your browser, or use web beacons, IP addresses, and other identifiers to collect information as a result of ad serving on this site.
You can manage or opt out of personalized Google advertising in Google Ads Settings. Learn more about how Google uses information from sites that use its services. Your browser may also offer controls for cookies. These choices do not prevent all technical data processing needed to deliver a page.
Changes to this policy
We will update this page and its date when the site's data practices materially change. Review this page for the current description before submitting material to a tool.
