Privacy

Last updated 16 October 2026

Short version: what you put into a tool stays on your device. We don’t have accounts, we don’t set cookies, and we can’t see your input.

Your input

Every tool runs as code inside your browser tab. Tokens, keys, files and text you enter are processed on your device and are never sent to our server or anyone else. When you close the tab, they are gone. Secrets and keys you enter are never written to storage.

What is stored in your browser

  • Theme preference (light, dark or system), if you change it.
  • Recent tools: the names of the last few tools you opened, so they can be shown on the home page. This never includes what you entered into them.
  • Offline copy of the site: your browser caches the site’s files so the tools work without a connection.

This is stored with your browser’s local storage and cache, not in cookies, and it never leaves your device. Clearing your site data removes it.

Analytics

We use a self-hosted copy of Umami to count page views and which tools are used. It does not use cookies, does not collect personal data, and respects your browser’s Do Not Track setting. Events contain the tool name and the action (for example “copied the result”), never your input. If a tool hits an unexpected error, we record the error type and page so we can fix it, but not the error message, because it could contain part of your input.

Server logs

Like any website, our web server and CDN (Cloudflare) see standard request information such as your IP address and the page requested. These logs are used only for security and to keep the site running, and are deleted after a short period.
