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

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.
