Privacy policy
Last updated: 11 October 2026
HeySpeak is an app for learning English vocabulary. This page explains what data we process, why, and what your rights are. The data controller is Julien Petit, reachable at support@heyspeak.me.
In short
- You can use the app without creating an account.
- We don't sell your data and we show no ads.
- Your voice recordings are transcribed, then not kept.
- You can delete your account from inside the app at any time.
The data we process
| Data | Why | Legal basis |
|---|---|---|
| A random device identifier | To save your progress without an account. | Providing the service |
| Your progress: words seen, levels, answers, streak | To schedule your reviews and sync your devices. | Providing the service |
| Email address and password (hashed), if you create an account | To sign you in and restore your progress on another device. | Providing the service |
| Your voice, when you answer out loud | To turn it into text and check your answer. The audio is not kept after transcription. | Providing the service |
| Sentences you type or say (for example "Ma journée") | To build vocabulary cards from your sentence. | Providing the service |
| Subscription status and purchase history | To unlock Premium. We never see your card details: Apple or Google handles payment. | Performing the contract |
| Usage data: screens opened, sessions, device model, app version | To understand what works and fix bugs. | Legitimate interest |
Service providers
We share only what each service needs:
- Cloudflare: delivering pictures and audio.
- AssemblyAI and Groq: voice transcription and sentence processing (United States).
- Microsoft Azure: text-to-speech for words (no personal data sent).
- RevenueCat, Apple and Google: subscription management.
- PostHog (servers in the European Union): usage analytics.
- Expo: app updates.
Where data leaves the European Union, the transfer relies on the European Commission's Standard Contractual Clauses or the Data Privacy Framework.
How long we keep it
We keep your progress and account for as long as you use the app. If you delete your account, this data is erased within 30 days. Usage data is kept for 24 months at most.
Children
HeySpeak is not meant for children under 13 and does not knowingly collect personal data from them. If you believe a child has sent us data, write to us and we will delete it.
Your rights
You can access, correct, delete or export your data, object to its processing or restrict it. To delete your account: Profile → Account → Delete my account and my data in the app. For anything else, write to support@heyspeak.me; we answer within one month.
You can also complain to your data protection authority; in France, the CNIL (cnil.fr).
Changes
If we change this policy in a meaningful way, we will tell you in the app. The date at the top of this page shows the last update.
