Privacy: your text never leaves your browser

Every Toolflect Text Tool is 100% client-side. The moment you type or paste text, it is analyzed by JavaScript running inside this browser tab. Your text is never sent to our servers, never stored in a database, and never shared with any third party or AI service.

  • No uploads, no accounts, no sign-up
  • No cookies or tracking of your text
  • Works offline once the page has loaded
  • Close the tab and your text is gone from memory

You can even verify it yourself: open your browser's developer tools, switch to the Network tab, and type into the tool — the only requests you will ever see are this page's own static files (HTML, CSS, JavaScript). Nothing you type is ever transmitted.

Frequently asked questions

Does it validate while formatting?
Yes — invalid JSON produces a clear inline error instead of garbage output.
Can I change the indentation?
Switch between 2 spaces, 4 spaces or a tab from the Indent control.
Are non-ASCII values preserved?
Absolutely — Arabic text and emoji pass through unchanged.
Does anything get uploaded?
No — formatting happens entirely inside your browser.
