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. Visit counting (see the note at the foot of this page) is separate from your text and never receives it.

  • No uploads, no accounts, no sign-up
  • Your text is processed locally in your browser and never stored.
  • 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 — no request ever carries your text. You will also see the Google Analytics request that counts the visit; it carries a page view and never anything you typed, and no cookie or identifier is stored until you accept analytics.

Frequently asked questions

Why do emoji use two escapes?
Characters beyond U+FFFF are represented in JavaScript as surrogate pairs, so the encoder emits both halves — exactly what a literal would contain.
Is printable ASCII preserved?
Yes — letters, digits and common punctuation stay readable; only non-ASCII and control characters are escaped.
Is this valid JavaScript?
Yes — the output can be pasted directly into a string literal.
Does escaping leave the browser?
No — encoding runs entirely locally.
