Proofish stores puzzle progress, mistakes, completion badges and final visit times in your browser. Clearing site data removes these records. They are not synchronized across devices, and progress does not transfer automatically between website addresses (for example, proofish.pages.dev and proofish.io).

This version has no player accounts, advertising scripts or analytics. Hosting is provided by Cloudflare, which processes connection information such as IP addresses and request details to deliver and protect the site. See Cloudflare’s privacy policy.

Copying a result writes spoiler-free text to your clipboard only when you press the share button. Proofish does not read your clipboard. If you email us, your email provider and ours process the message and the contact details you choose to send; please do not send payment details or sensitive personal information.

Advertising is planned but is not active. We will update this notice and any required consent controls before enabling advertising.
