Privacy Policy

JWorld Games (games.jworld.dev) requires no account registration and does not collect personal information such as your name, email address, or phone number.

Local Browser Storage

Your game progress (high scores, coins, upgrades, and preferences) is stored exclusively in your browser's localStorage on your device. Clearing your browser site data resets this local progress.

Anonymous Gameplay Telemetry

To balance difficulty and improve gameplay, starting or finishing a run sends anonymous gameplay metrics (game title, survival time, enemies defeated, stage, character, Daily Run flag, language, referrer domain, and a random per-browser token) to our Cloudflare worker. No names, contact details, or IP addresses are stored.

Web Analytics & Advertising

We use cookie-free Cloudflare Web Analytics to measure aggregate traffic. Game guide pages may display Google AdSense advertisements, which may use cookies to serve relevant ads. You can manage personalized ad preferences at Google Ad Settings.
