Privacy Policy

Last updated: October 2026

1. 100% Client-Side Processing Guarantee

PureTTS is engineered with a strict privacy-first architecture. Any text you enter or audio you synthesize is processed entirely within your browser's local memory using WebAssembly and WebGPU. Your text and audio are never transmitted to, saved on, or analyzed by any external server.

2. Cookies and Third-Party Advertising

To keep this tool 100% free with no subscriptions or character limits, we may display third-party advertisements (such as Google AdSense).

• Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to our site and/or other sites on the Internet.
• Users may opt out of personalized advertising by visiting Google Ads Settings.

3. Local Storage and Model Caching

This website uses standard browser Cache Storage API (Cache / OPFS) to store public neural model weights locally on your device. This allows subsequent speech conversions to execute instantly and work offline without re-downloading files.
