This page describes the current technical behavior of marcel.tools and does not promise features that are not operated.
Tool work content
JSON, Base64 text, UUID output, and analyzed text are processed in your browser. They are not transmitted, logged, or persisted.
Local storage
The browser stores only the selected appearance and stable tool IDs for favorites and recently opened tools. No tool input or result is stored.
Browser capabilities
Clipboard access happens only after an explicit click. UUID generation uses Web Crypto locally. There are no analytics, advertising, or tracking scripts.
Website delivery
The hosting provider necessarily processes HTTP connection data such as IP address, time, requested route, and browser identifier when delivering the site.
