Privacy policy.

Last updated: May 2026

The short version

We don't ask you for personal information. Every conversion happens in your browser — your text never reaches our server because we don't have a server that processes text. We use Google Analytics for aggregate page-view counts; nothing about your text or your conversions is sent anywhere.

What stays on your device

  • The text you type. All case conversion runs in JavaScript in your browser. We never see what you converted.
  • The files you upload. File upload reads the file with the browser's FileReader API and converts it locally. The file never leaves your device.
  • Your settings. Mode preferences, style-guide choice, theme, diff/explain toggles — all saved in your browser's local storage.
  • Custom proper nouns. If you add personal terms to the dictionary in a future version, they stay on your device.

What our hosting can see

Standard web logs — your IP address, browser type, the URL you visited, and a timestamp — are kept by our static-file host for a few days for security and operational purposes. We don't query these for marketing or profiling.

Third-party services we use

Google Analytics

We use GA to count page views and understand which sections of the site are used. Google receives your IP, a cookie identifier, browser info, and the pages you visit. We use a 14-month retention. See Google's privacy policy. Opt out at Google Analytics Opt-out.

Fonts

Typefaces (Fraunces, Geist, JetBrains Mono) are self-hosted from our own server. No request is made to Google Fonts or any other third-party font service, so no font-related data is shared with anyone.

Ad networks

If we display banner ads via Google AdSense or another network, those networks may use cookies to serve and measure ads. They act as independent data controllers. See how Google uses ads data and opt out at Google Ads Settings.

Browser extension

The Transform Case browser extension (Chrome, Edge, Brave) follows the same principle as the website: your text is processed locally and never transmitted anywhere.

  • Text you select and convert. Read only at the moment you trigger a conversion via the right-click menu, popup, or keyboard shortcut. Never logged, stored, or transmitted — including to us.
  • Your style preference and custom terms. Saved using the browser's storage API, entirely on your device. We have no access to this data and it is never sent to any server.
  • The clipboard. Used only to copy a conversion result when the selected text is on a read-only part of a page and can't be replaced in place. Nothing is read from your clipboard — only written to it, and only as a direct result of your own action.

The extension requests four permissions — contextMenus (the right-click menu), storage (saving your preferences locally), activeTab (acting on the tab you're using, only when you trigger it), and clipboardWrite (copying results as described above). It does not sell or transfer any data to third parties, and does not use data for any purpose beyond the conversion feature itself.
