Política de privacidad

Última actualización: March 20, 2026

STT.ai ("nosotros", "nosotros" o "nuestro") está comprometido a proteger su privacidad. Esta Política de privacidad explica qué información recopilamos, cómo la usamos y qué opciones tiene. Al usar STT.ai, acepta las prácticas descritas en esta política.

1. Información que recopilamos

Información de la cuenta

When you create an account, we collect your email address and, optionally, your name. If you sign in through a third-party provider (e.g., Google), we receive basic profile information from that provider.

Información de pago

When you purchase credits or subscriptions, payment is processed by our third-party payment providers (Stripe, Square). We do not store your full credit card number. We retain transaction records (amount, date, and payment method type) for accounting purposes.

Archivos de audio

When you upload audio for transcription, your files are sent to our GPU server for processing and deleted immediately after transcription is complete. We do not permanently store your audio files. Audio is transmitted over HTTPS (TLS 1.3) and processed in memory.

When you provide a URL for transcription (e.g., a YouTube or podcast link), the audio may be temporarily downloaded to disk on our server using yt-dlp before processing. These temporary files are deleted immediately after transcription is complete. The URL you provide is not stored after processing.

Transcripciones

Generated transcripts are stored in your account so you can access them later. If you enable client-side encryption, the transcript is encrypted in your browser before being saved to our servers — we cannot read the stored version. Note: during processing, the server handles the transcript in plaintext before returning it to your browser for encryption. You may delete your transcripts at any time.

Datos de uso

We collect basic usage information such as pages visited, features used, transcription requests made, timestamps, browser type, and IP address. This helps us improve the Service and diagnose issues.

2. Encriptación de Cero Conocimientos

STT.ai offers an optional client-side encryption mode for stored transcripts. When enabled, your transcript is encrypted in your browser using AES-256-GCM with a key derived from your password before being saved to our servers. We never have access to your encryption keys, and cannot read or recover encrypted transcripts. Note: audio must be sent unencrypted to our GPU for transcription — the encryption protects the stored transcript, not the processing step. For more details, visit our Security page.

3. Cómo usamos su información

We use collected information to:

• Provide, maintain, and improve the Service.
• Process transactions and manage your account.
• Send transactional emails (receipts, account notifications, security alerts).
• Monitor for abuse and enforce our Términos de servicio.
• Analyze aggregate usage trends to improve performance and features.

6. Contribuciones del laboratorio de voz

STT.ai offers an optional Voice Lab program where you can contribute audio samples to help improve open-source speech recognition models. Participation is entirely voluntary and opt-in. Contributed audio is licensed under CC-BY-SA and may be included in publicly available datasets used to train open-source models. You can withdraw from the Voice Lab at any time through your account settings. Contributions made prior to withdrawal that have already been incorporated into released datasets may not be removable.

7. Gestión de datos API

If you use the STT.ai API, the same privacy protections apply. Audio submitted via the API is processed and deleted immediately. API request metadata (timestamps, endpoints, response codes) is logged for rate limiting and debugging purposes and is retained for up to 90 days.

8. Retención y supresión de datos

We retain different types of data for different periods:

• Audio files: Deleted immediately after transcription is complete. This includes both uploaded files and files temporarily downloaded from URLs.
• Transcripts: Stored until you delete them or until your account is deleted.
• Account data: Retained while your account is active. After account deletion, personal information is removed within 30 days, except where retention is required by law.
• Usage and analytics data: Anonymized after 90 days.
• Payment records: Retained as required by applicable tax and financial regulations.

You may delete your account at any time through your account settings or by emailing hello@stt.ai. When you delete your account, we remove your personal information and transcripts within 30 days, except where retention is required by law.
