Privacy Notice
DiffText Pro is designed with privacy as a core principle. All text comparison is performed locally in your browser using JavaScript. We do not store, transmit, or have access to your text data. Comparison history is saved using IndexedDB (browser storage) on your device only. When you use the "Share" feature, your text is encoded in the URL for easy sharing, so be mindful when sharing sensitive content via this method. We support this free tool through non-intrusive display advertising.
