Questions about text tools

Does my data get uploaded anywhere?
Every tool in this category runs its processing in your browser using ordinary JavaScript. Your input is not sent to a server, and it is not written to storage when you leave the page.
Can I use these tools on a phone?
Yes. The layouts adapt to narrow screens, editors stack vertically instead of side by side, and copy buttons stay reachable without horizontal scrolling.
