Privacy Policy

1. Zero Audio or Text Collection

The core principle of Crematic is absolute local execution:

• Zero Cloud Inference: Your text prompts and synthesized voice audio are processed entirely inside your local browser via a dedicated Web Worker and the Web Audio API.
• No Audio Storage: Neither your text inputs nor your generated WAV files are ever transmitted to, recorded by, or stored on our servers.
• No Model Training: We do not capture or utilize your inputs or audio for training machine learning models.

2. Local Storage & Browser Caching

Crematic uses standard client-side browser storage mechanisms solely to improve application performance:

• Browser Cache Storage: When neural voice model files are fetched from the CDN, the browser caches the model weights locally so future visits load without re-downloading.
• Preferences (localStorage): The keys crematic-voice and crematic-draft are stored locally on your device to remember your settings and draft. You can clear this anytime through your browser settings.

3. Server Logging & Hosting Infrastructure

When you load the web application, the hosting infrastructure (such as Vercel, Cloudflare, or our web host) automatically logs standard HTTP access metrics necessary for security, performance, and DDoS prevention:

• Internet Protocol (IP) address
• Browser type and version (User-Agent)
• Referring website addresses and access timestamps

These server logs are used strictly for technical security and operational uptime, never linked to personal identities.

4. Third-Party CDNs & External Resources

During initialization, your browser fetches open-weight model artifacts from Hugging Face's Content Delivery Network. Hugging Face handles those static file requests subject to their own privacy policy.

5. Global Privacy Rights (GDPR, CCPA / CPRA)

Because Crematic does not collect or store personal profiles, email addresses, or user content on server databases, we do not sell, rent, or trade your personal information. Under the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), your data rights are naturally protected by our zero-knowledge, on-device architecture.

6. Children's Online Privacy Protection (COPPA)

Crematic is not intended for or directed toward children under the age of 13. We do not knowingly collect or solicit any personal data from children.

7. Process Memory & Security Isolation

The application enforces cross-origin isolation policies (COOP and COEP credentialless headers) to safeguard browser process memory and ensure sandboxed, private Web Worker execution.
