Política de Privacidad

Última actualización: 18 de marzo de 2026 · Versión 1.1

Hey, Rick here. Privacy policies are usually boring walls of legal text. I'll keep this as human as possible. The short version: your data is yours. We only collect what we need to make Dutch Fluency work for you, and we never sell it. Así de simple.

Quiénes somos

Dutch Fluency is a language learning platform created by Rick (that's me) based in Bangkok, Thailand. We provide podcasts, interactive apps, coaching, and reading materials for people learning Dutch. Our website is dutchfluency.com and our dashboard lives at dashboard.dutchfluency.com.

Qué recopilamos

Información de la cuenta

Tu nombre y correo electrónico cuando te registras en las apps, transcripciones, entrenamiento por correo o la evaluación. Eso es todo. Sin número de teléfono, dirección ni talla de zapato.

Información de pago

Handled entirely by Stripe. We never see or store your card details. Stripe is PCI-DSS compliant (fancy way of saying: they take security seriously).

Datos de uso

Seguimos tu progreso (XP, rachas, ejercicios completados) para que puedas ver cuánto has avanzado. También usamos analíticas básicas (vistas de página, clics) a través de Google Analytics y Microsoft Clarity para entender qué páginas son útiles.

Entradas del diario (Dagboek)

Si usas el Dagboek, tus entradas se almacenan para que puedas revisarlas después. Son tuyas. No las leemos, compartimos ni usamos para nada más que proporcionarte el servicio.

Cookies

Usamos una cookie de preferencia de idioma (df-locale) and essential session cookies. No tracking cookies, no ad cookies, no creepy follow-you-around-the-internet cookies.

Grabaciones de voz

If you use pronunciation practice (Fluency Tulip, speaking challenges), we record your audio. This is sent to OpenAI Whisper for transcription and Claude AI (Anthropic) for feedback. Voice data may be considered biometric data under GDPR Article 9 — we only process it with your explicit consent, which you can withdraw anytime.

Contenido procesado por IA

Your writing (Dagboek entries, challenge submissions) and conversations with our AI tutor are processed by Claude AI (Anthropic) to give you personalized feedback. Your "Jouw Podcast" intake data is used to generate custom episodes. We send only the minimum data needed — never your email, password, or payment info.

Cómo usamos tus datos

  • 1. To provide the service (apps, podcasts, transcripts, coaching)
  • 2. To send you things you signed up for (email training, assessment results)
  • 3. To improve Dutch Fluency (understanding which apps people actually use)
  • 4. To process payments (via Stripe)

We never sell your data. We never share it with advertisers. We never use it to train AI models. Full stop.

Usamos estos servicios de confianza para operar Dutch Fluency:

  • Anthropic (Claude AI) — writing feedback, speaking analysis, AI conversations (USA)
  • OpenAI (Whisper) — speech-to-text transcription for voice exercises (USA)
  • ElevenLabs — text-to-speech audio generation for podcasts and lessons (USA)

Base legal (RGPD)

Para los amantes de lo legal: aquí te explicamos por qué procesamos tus datos:

  • Contrato (Art. 6(1)(b)) — providing the learning platform, processing payments
  • Consentimiento (Art. 6(1)(a)) — AI-powered feedback, personalized content, email notifications
  • Consentimiento explícito (Art. 9(2)(a)) — voice recording processing (biometric data)
  • Interés legítimo (Art. 6(1)(f)) — account security, fraud prevention, service improvement

Tus derechos

Según el RGPD, siempre puedes:

  • Access your data (Art. 15) — download it from your dashboard Settings, or ask us
  • Correct your data (Art. 16) — wrong email? Name change? Just tell us
  • Delete your data (Art. 17) — delete your account in Settings, or email us. We'll wipe everything within 30 days
  • Export your data (Art. 20) — download a JSON export from your dashboard Settings
  • Retirar el consentimiento (Art. 7(3)) — revoke voice recording or AI processing consent anytime in Settings
  • Cancelar suscripción from emails — every email has an unsubscribe link

We respond to all data requests within 30 days. You can also lodge a complaint with the Autoriteit Persoonsgegevens (Dutch Data Protection Authority) at autoriteitpersoonsgegevens.nl.

Seguridad de los datos

Nos tomamos la seguridad muy en serio:

  • Todas las conexiones cifradas con HTTPS (TLS)
  • Contraseñas cifradas con bcrypt (12 rondas de sal)
  • Contenido sensible (diarios, conversaciones, transcripciones de voz) cifrado en reposo con AES-256-GCM
  • Control de acceso basado en roles para todos los sistemas internos
  • Límite de velocidad y protección CAPTCHA contra abusos
  • Escaneo de seguridad automatizado en cada cambio de código
  • Datos personales redactados automáticamente de los registros de aplicación

Retención de datos

We keep your data as long as you have an account. If you cancel your subscription, your account and data remain so you can come back anytime. If you want everything deleted, email us and we'll wipe it within 30 days.

Children

Dutch Fluency is designed for adults learning Dutch. We don't knowingly collect data from anyone under 16. If you're a parent and think your child signed up, reach out and we'll remove their data.

Changes

If we update this policy, we'll post the changes here. No sneaky edits. For major changes, we'll send an email.

¿Preguntas?

Privacy stuff can feel abstract. If you have any questions about your data, just email me directly at [email protected]. I'll reply personally. Geen probleem.
