Privacy & data use

What your browser stores

Your browser stores preferences such as the color theme and sound setting, personal bests, cleared Skyline Run levels, and recent Room Rush themes and product IDs. These help remember your choices and vary future rounds. You can remove them by clearing this site's data in your browser; doing so also resets those preferences and progress.

What a live AI game sends

Live AI play sends the information needed for the game to our servers and Jev. In Room Rush, this includes your room choice, written brief and round context. Recent product IDs help avoid repeating finds. Skyline Run sends game state for upcoming route decisions; its local practice mode does not request Jev decisions.

If you choose to generate a room image, your brief, selected product descriptions and available product reference images are sent through Vercel AI Gateway to the image provider. This happens when you request the image, not merely when you open the page.

In Thing Finder, a search sends your written description and the fixed object catalog through our server to Jev. This happens after a pause in typing, when you press Enter, or when you select an example. Simply opening the page or dragging objects does not send a Jev request. Search descriptions are not sent as analytics event data.

Results and their storage

Room Rush receipts and their generated images have a 48-hour validity period from receipt creation. The receipt store schedules deletion of those records after that period. This does not describe how long an upstream provider keeps its own records.

The public leaderboard is stored separately. It contains a run ID, room type, product count, elapsed time and completion time, without your written brief. Leaderboard entries are not covered by the receipt's 48-hour expiry.

Usage measurement and service providers

We use Google Analytics 4 to understand page visits, language choices and game events such as starts, finishes, durations and errors. Our game-event fields are restricted to allowed values; written briefs, Thing Finder search descriptions and generated images are not sent as game-event data. Google signals and ad personalization signals are disabled in our analytics configuration. Google Analytics may use cookies and browser or device information.

Cloudflare hosts the site and its game services. Hosting, analytics and AI providers may process connection information and service logs under their own policies. Opening an external product link takes you to that site's own data practices. Provider privacy information is linked below.

Questions and data requests

Contact CrazyJev about privacy, your results, or a deletion request. Include the game and approximate time of your visit so we can investigate. Clearing browser data does not remove server-side records. We will explain what we can identify and handle; there is no automatic deletion tool on this site.
