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

Are decimals and negatives included?
Yes — values like -3.5 and 0.25 are extracted with their sign and point.
What about thousand separators?
Comma-grouped figures such as 1,250,000 are matched as one number.
Do Arabic-Indic digits work?
Matching covers Western 0-9; convert ٠-٩ first if your source uses them.
Does any data leave the page?
No — scanning happens locally and the list never leaves your browser.
