Privacy Policy

Last updated: March 30, 2026

At TTS Free by AITYTECH, we take your privacy seriously. This policy explains how our service handles your data.

Summary

We don't collect, store, or sell your personal data. Our service is designed with privacy as a core principle.

Text-to-Speech

• Your text is sent to Microsoft's Edge TTS service for speech synthesis. We act as a proxy and do not store, log, or cache your text on our servers.
• The generated audio is returned directly to your browser and is not saved on our servers.
• Microsoft's own privacy policies apply to the text processing. Please refer to Microsoft's Privacy Statement for details.

Audio Tools (Trimmer, Converter, Noise Reduction, Speech-to-Text)

• All audio processing happens entirely in your browser using WebAssembly, GPU acceleration, and Web Audio API.
• Your audio files are never uploaded to any server. They stay on your device at all times.
• AI models (like Whisper for speech-to-text) are downloaded to your browser and run locally. The model files are cached in your browser's storage.

Cookies & Local Storage

• We use browser localStorage to save your preferences (dark mode, last-used voice, language settings). This data never leaves your device.
• We do not use tracking cookies or third-party analytics services.
• AI model files may be cached in your browser's IndexedDB for faster subsequent loads.

Third-Party Services

• Microsoft Edge TTS - Used for text-to-speech synthesis. Text is sent to Microsoft's servers.
• Hugging Face CDN - Used to download Whisper AI models for local speech-to-text processing.
• jsDelivr CDN - Used to serve open-source JavaScript libraries (Alpine.js, Tailwind CSS, FFmpeg.wasm).
• Cloudflare - Our hosting provider. Standard Cloudflare analytics may apply.

Data Retention

We retain no user data. There are no accounts, no databases of user content, and no server-side logs of your text or audio. Your browser's local storage and cache are the only places where any data persists, and you can clear them at any time.

Children's Privacy

Our service is available to users of all ages. We do not knowingly collect any personal information from anyone, including children.

Changes to This Policy

We may update this policy from time to time. Changes will be reflected on this page with an updated date.
