Privacy & Local Game Progress

The site has no account registration, checkout, newsletter or first-party visitor analytics at launch. Calculator entries remain in your browser and are not sent by the tools to our server.

Return Challenge saves unlocked levels and your best round score in browser-local storage. Clearing this site’s browser data removes that progress. It does not create a global leaderboard or identify you.

The hosting service processes ordinary web requests to deliver pages. Product images load from Amazon’s image servers; following affiliate or manufacturer links opens a third-party site with its own privacy practices.

Do not enter personal or sensitive information into the tools. Future changes to measurement or storage will require an updated privacy explanation.
