Privacy

Rulecard is a hackathon demo on NEAR testnet. It has no accounts, no analytics and no cookies. This page says what it does keep and who your browser talks to.

What stays in your browser

When you press Play free, the app makes a practice wallet and keeps its key in your browser's local storage on this device. We never receive it. Use the app's Start over option, or clear this site's data, and it is gone. Sound and menu choices are kept there too.

What our server receives

The public address of your practice wallet, so a small amount of testnet NEAR can be sent to it. The sending service keeps your address in memory only, to avoid paying the same wallet twice.
Your IP address, held briefly in memory to limit how many practice wallets one visitor can request. It is not written to a database.

Other services your browser contacts

Google Fonts and unpkg, which serve the typeface and the icons. They see your IP address and browser details.
NEAR testnet RPC providers (FastNEAR, dRPC and the NEAR archival node), which receive the requests the app makes, including your practice wallet's public address.
Vercel, which hosts this site and keeps standard server logs.

Everything onchain is public

Transactions on NEAR testnet are public. Anything you do in a coin is visible to everyone, tied to your wallet address.
