Privacy Policy

What GuestbookETH collects and makes public

When you connect a wallet, GuestbookETH reads the public wallet address needed to show connection status and to submit or display guestbook activity. When you sign the guestbook, your message, wallet address, transaction details, and timestamp are recorded on the Ethereum blockchain.

Do not submit personal, confidential, or sensitive information in a guestbook message. Once the transaction is confirmed, the message is public and permanent on-chain. GuestbookETH cannot edit, remove, or make that content private.

Cookies, analytics, and advertising

GuestbookETH does not currently include an analytics service, advertising network, or advertising script. It does not intentionally set analytics or advertising cookies. If analytics or advertising, including Google AdSense, is added later, this policy and the site's cookie notice will be updated to explain the relevant tracking and choices.

Third-party services

Wallet connections are handled through the wallet extension or browser wallet you choose and the site's wallet-connection software. Ethereum requests are sent through blockchain RPC infrastructure selected by the application or your wallet, and confirmed guestbook entries are stored on the Ethereum network. Those providers and the Ethereum network may receive information such as your public wallet address, transaction data, device or browser information, and IP address under their own privacy practices.

The site also loads fonts from Google Fonts. Google may receive your IP address and standard browser request information when those fonts load.

Privacy questions

For questions about this policy or privacy at GuestbookETH, please use the Contact Us page. Because blockchain records are decentralized and immutable, we cannot delete a confirmed on-chain message or transaction.
