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

How is density calculated?
Density = occurrences ÷ total words × 100, per word. Case is ignored so 'Seo' and 'seo' count as one keyword.
Why filter by length?
Short words like 'the' and 'and' dominate raw counts; a minimum length lets you focus on real keywords.
Is there a recommended density?
No hard rule — density is a diagnostic. Our tool reports the number honestly rather than suggesting a target.
Private?
Fully — analysis runs locally in your tab; your text never leaves the browser.
