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.
