712 Tools is a static website. The tools on this site run entirely in your browser using JavaScript APIs like JSON.parse, RegExp, and atob. Any data you paste — JSON, regex patterns, tokens, URLs, CSS, HTML, cron expressions — stays on your device.

We do not upload your data to a server. We do not store it in a database. We do not read it. The site has no backend at all.

The site may load standard analytics or ad scripts to keep the tools free — those services may collect anonymous usage data (page views, referrers, device type) as they normally do. They do not have access to the contents you paste into the tools themselves.

Your theme preference is stored in localStorage on your device. Nothing else is stored client-side.
