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

Why does Base64 matter for non-English text?
Classic btoa() breaks on characters outside Latin-1. This encoder goes through UTF-8 bytes first, so Arabic, Cyrillic and emoji survive intact.
What is the = padding?
Base64 pads incomplete byte groups with = signs — output stays standard and interoperable.
Can it encode binary files?
This tool is text-oriented; feed it pasted text content and it encodes exactly those characters.
Is anything uploaded?
Never — encoding happens entirely inside your browser tab.
