Sproochentest privacy policy · Fly Infinity Studio

01Summary

Sproochentest is the one app in our catalogue that does collect personal data, because it has accounts and a subscription. We would rather state that plainly than bury it.

Signing in with Google gives us your name, email address and profile picture. A subscription gives us your purchase history through Google Play. Both exist so your progress and premium access follow you across devices.

The accent checker records your voice only while you are using it, and sends that audio to the Sproochmaschinn.lu speech service for transcription. The microphone is never used in the background.

You can delete your account and all associated data at any time. Requests are processed within 30 days.

04Information we collect

Account information: When you sign in with Google we receive your name, email address and profile picture. This identifies your account so your progress and premium status are available on any device you sign in on.
Purchase history: If you subscribe, Google Play Billing tells us that a valid subscription exists for your account. We never receive or store your card details or billing address.
Voice recordings: The accent checker records your voice while you are actively using that feature, and sends the audio to the Sproochmaschinn.lu speech service so it can be transcribed and assessed. Recording only happens while the feature is open.
Device diagnostics and log data: Standard diagnostic and log information associated with requests, used to keep the app working and to investigate faults.
Study progress: Which questions and exercises you have completed, and your practice streak, so the app can resume where you left off.

05Permissions

Microphone: Used exclusively to provide pronunciation feedback in the accent checker. The app does not record in the background and does not listen at any other time. Denying this permission leaves every other feature fully usable.
Notifications: Used for daily study reminders and motivational prompts. Optional, and you can turn them off in Android settings or in the app.
Internet and network state: Used to sign in, sync progress, stream audio and radio, generate speech, and load advertisements. Audio you have already played is cached and replays offline.

06Data sharing

We do not sell your personal data and we do not share it for advertising purposes. Data is shared only with the service providers listed in the third-party section above, and only to the extent each one needs in order to do its job — Firebase to store your account and progress, Google Play to validate a subscription, Sproochmaschinn.lu to process speech, and Google AdMob to serve advertisements in the free tier.

07Data retention and account deletion

Your account data is retained while your account exists, so your progress and premium status are preserved. You can delete it at any time:

Email us with the subject line "Delete My Account" from the address associated with your account.
We process deletion requests within 30 days of receipt.
Deletion removes your account record, study progress and premium record from our systems.
Voice recordings sent to the speech service are processed for transcription and are not retained by us.

08Consent, GDPR and regional rights

If you are in the European Economic Area, the United Kingdom or Switzerland, you have the right to access, correct, export and erase your personal data, to object to or restrict its processing, to withdraw consent, and to lodge a complaint with your national data protection authority. Luxembourg’s authority is the Commission nationale pour la protection des données (CNPD).

Withdraw or change advertising consent in the app under Settings → Privacy Settings.
Request access to or deletion of your data by email; we respond within 30 days.
Reset or delete your advertising ID from Settings → Google → Ads on your device.
Subscribe to remove advertising entirely.

09Children’s privacy

The app does not knowingly collect personally identifiable information from children under the age of 13. It is intended for adults preparing for a citizenship language examination. If you believe a child has provided us with personal information, contact us and we will delete it.

10Security

All data is sent over an encrypted connection. Authentication is handled by Firebase Authentication rather than by us storing passwords, and subscription state is validated against Google Play rather than trusted from the device. No system is perfect, but we do not hold payment details and we keep the data we do hold to the minimum the app needs.

11Your rights and choices

Use the app without an account for the features that do not require one.
Revoke the microphone permission at any time; only the accent checker depends on it.
Turn off study notifications in the app or in Android settings.
Request a copy of your data, or its deletion, by email.
Manage or cancel your subscription from the Google Play Store at any time.

12Changes to this policy

We may update this policy from time to time. Material changes will be reflected here with a new "Last updated" date. Continued use of the app after a change constitutes acceptance of the updated policy.

13Contact

If you have any questions about this privacy policy, or about how Sproochentest handles information, contact us and we will respond.
