Privacy and data use
Your tool input stays in the browser. Website analytics, hosting logs and optional preferences are separate from that input.
Text, files and results
Text and imported files are processed in the current tab's memory, including Web Workers. We do not intentionally send input, filenames, search/replace values or output to our server or analytics. Text is not stored in localStorage or IndexedDB. Closing or refreshing the tab clears it. Copy and download happen only when you request them; downloaded files remain on your device.
Theme preference
We store only the selected light, dark or system theme under comparetext-theme in localStorage. You can remove it through your browser's site-data controls. Blocking storage does not prevent the tools from working.
Google Analytics
The production website uses Google Analytics 4 to understand visits and tool usage. Events include page views, successful operations, sample use and successful copies, with tool, language and fixed operation settings. Google may use cookies or identifiers and process browser/device, referral and usage information. These statistics do not include your tool text. Google handles this information under its privacy policies.
Your choices
You can control or delete cookies and site data in your browser, use tracking protection or Google's Analytics opt-out browser add-on. Blocking analytics does not disable the tools. See the links below for Google's data-use explanation and opt-out add-on.
Hosting and external services
Hosting and Cloudflare may process ordinary access logs such as IP address, requested URL and time to deliver and protect the website. Contact links open email or Telegram, which follow their own policies. Browser extensions and your clipboard or downloaded files are outside this site's memory-only workflow.
Advertising and updates
This release does not load advertising code. If advertising is introduced, we will update these disclosures and configure the applicable consent controls before serving it. For questions about this policy, use the contact links below. Updated 16 September 2026.
