Privacy & saved data

Short version: your code stays on your device unless you press an AI button.

Tools run in your browser

Formatting, minifying, validating, converting, diffing, regex testing, Base64/URL/JWT decoding and UUID generation all run in JavaScript inside the page. The text you paste is not sent to a server.

What is saved on your device

To stop a refresh from losing your work, each tool remembers its last input and a few settings (indent size, SQL dialect, diff view) in your browser’s localStorage, under keys starting with cc:. It never leaves your device and there are no accounts.

AI features

A few buttons — Fix with AI on formatter pages and Explain / Write it on the regex tester — send the relevant text (capped at 6,000 characters) to our server, which forwards it through Vercel AI Gateway to an OpenAI model to produce the answer. This happens only when you click. We don’t store the text or the answer. Don’t send secrets, credentials or personal data to an AI feature.

Analytics

We use Ahrefs Web Analytics to count page views. It does not use cookies and does not see what you type into the tools.

Hosting

The site is hosted on Vercel, which keeps standard server logs (such as IP address and requested URL) for security and operations.
