Local Processing

All software developed by STZ LABS (CSV Converter, XML Translator, Lyrics, Suite) is designed to process data locally on your machine. We do not send your files, contacts, or XMLs to proprietary servers.

STZ AI Chat Optimizer Extension

The STZ AI Chat Optimizer extension is designed to improve usability and interface clarity in long chats while running locally in the user's browser.

• The extension uses browser local storage only to save user preferences, such as visible amount, hiding mode, enabled sites, and language/interface settings.
• It acts on the visual interface of supported pages to hide or collapse older messages and make long conversations easier to navigate.
• Conversation content is not sent to STZ LABS servers.
• STZ LABS does not sell or share the user's personal data with third parties through this extension.
• Optional external links, such as the support page, are opened only when the user clicks them.

Third-Party APIs

Some tools use external services to function:

• Google Gemini API: In Game XML Translator, if you choose to use automatic translation, the text is sent directly from your computer to Google's servers. Your API Key is stored locally only.
• LRCLIB: STZ Lyrics queries the public LRCLIB database to display lyrics.

Site Analytics

This site uses Vercel Analytics and Vercel Speed Insights to measure visits and real loading performance. Neither uses cookies or creates a permanent identifier: each visitor is turned into a scrambled code derived from request data (such as IP and browser), and that code changes every 24 hours, which prevents following the same person across days or across sites. There is no profiling, advertising, or data selling. The processing relies on the legitimate interest of understanding site usage and keeping it fast, and it happens on Vercel servers abroad. To opt out, a tracker blocker or the browser's Do Not Track signal is enough.
