Why your files stay with you
Your device does the work
Each tool runs as a program inside your browser. There’s no server that sees your files and no account that stores them.
Other servers are blocked
This site’s security policy forbids connections to any other address. You can check in your browser’s network tab.
Works offline too
Once opened, the tools keep working without internet. Try it in flight mode, or install the site as an app.
