Politique de confidentialité
Dernière mise à jour : 18 mars 2026 · Version 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. Zo simpel is het.
Qui nous sommes
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.
Ce que nous collectons
Infos de compte
Ton nom et ton email quand tu t'inscris aux applis, aux transcriptions, à l'entraînement par email ou à l'évaluation. C'est tout. Pas de numéro de téléphone, pas d'adresse, pas de pointure.
Infos de paiement
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).
Données d'utilisation
Nous suivons ta progression (XP, séries, exercices terminés) pour que tu puisses voir le chemin parcouru. Nous utilisons aussi des analyses de base (pages vues, clics) via Google Analytics et Microsoft Clarity pour comprendre quelles pages sont utiles.
Entrées de journal (Dagboek)
Si tu utilises le Dagboek, tes entrées sont stockées pour que tu puisses les relire plus tard. Elles t'appartiennent. Nous ne les lisons pas, ne les partageons pas et ne les utilisons pas au-delà de la fourniture du service.
Cookies
Nous utilisons un cookie de préférence de langue (df-locale) and essential session cookies, plus our own first-party cookies that remember how you first found us and which ad you clicked, if any (df_ft, df_lc, df_anon), so we know which pages help people. We also count page visits ourselves, on our own server and never shared, whatever you choose in the cookie banner. If you visit from the EU, the EEA, the UK or Switzerland, Google Analytics, Microsoft Clarity and ad measurement cookies are only set when you choose "Accept all" in the cookie banner. Elsewhere they are on by default. With "Necessary only" those tools run without cookies. Wherever you are, you can change your choice anytime under "Cookie settings" at the bottom of every page.
Enregistrements vocaux
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.
Contenu traité par 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.
Comment nous utilisons tes données
- 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.

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.
Des questions ?
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.
