Privacy Policy

1. Overview

This policy describes how the Lingly app handles your data. Lingly has no server of its own. We collect nothing about you, store nothing about you, and see neither your learning progress nor the texts you write. There is no advertising, there are no analytics tools, there is no tracking, and nothing is passed on to third parties.

3. What data arises

Account data: an anonymous user identifier from Apple, your name and your email address – provided you sign in using „Sign in with Apple“ and choose to share these details.

Learning data: which lessons you have completed, which words and grammar notes are due and when, your XP, your streak, results from the placement test and the final tests, and the texts you write in the writing exercises.

Settings: course direction, daily goal, reminder time, sound, speech rate and feedback.

Microphone: only during a speaking exercise, and only while you are recording.

4. Where the data is held

All of it stays in the app on your device. The course content – words, grammar, conversations, reading texts – is part of the app and never leaves it. Lingly needs no internet connection in order to teach you.

5. Sync via iCloud

If you are signed in to iCloud, the app syncs your learning progress between your own devices. That data resides in your private iCloud database under your Apple ID, not with us. Apple is responsible for storing it, and Apple’s privacy terms apply. We have no access to it and can neither view nor restore your data. Only your progress is synced, not the course content.

6. Sign in with Apple

If you sign in with Apple, the app receives an anonymous identifier, your name and – if you permit it – an email address. Apple offers you the option of hiding your real address. These details remain on your device and in your iCloud and are not transmitted to us. The legal basis is your consent under Art. 6(1)(a) GDPR. You may withdraw it at any time by signing out or deleting your account.

7. Microphone and speech recognition

Speaking exercises require the microphone, and only while recording. Recordings are not stored and are not sent to us. Recognition is handled by Apple: if your device can recognise speech on its own, everything stays local – the app explicitly requests this wherever it is possible. If your device cannot, the recording is transmitted to Apple for recognition, and Apple’s terms then apply. Speaking exercises can be switched off entirely in Settings under „Sound & Feedback“.

8. Notifications

Lingly can remind you at two points: once a day at the time you set, and once when freshly learned material is due for its first review. Both notifications are scheduled on the device and triggered there. They run through no server, contain no data about you, and can be switched off in Settings.

9. Purchases and subscription

Lingly Pro is handled through the App Store. Payment data goes exclusively to Apple; we see neither your payment method nor your billing address. All the app learns from Apple is whether a valid subscription exists – no name, no number, no amount. Apple’s terms apply to payment processing.

10. No analytics, no advertising

Lingly contains no analytics tools, no advertising networks and no third-party libraries that collect data. There are no usage statistics, no crash reports to us, and no tracking across app or website boundaries. We do not know whether you use the app.

11. Retention and deletion

Your data remains for as long as you use the app. Under Profile → Reset data you delete your learning progress. Under Profile → Delete account you additionally remove your sign-in and your texts – from your iCloud as well, and therefore from your other devices. Neither can be undone, not even by us, because we hold no copy. If you delete the app, the iCloud state is kept until you next install it.

12. Your rights

You have the right of access, rectification, erasure, restriction of processing, data portability and objection (Art. 15 to 21 GDPR). Since we hold no data about you, the fastest route runs through your device and your Apple ID. For anything further you can reach us at info@lufystudios.de.

13. Right to lodge a complaint

You may lodge a complaint with a data protection supervisory authority. The authority responsible for us is:

Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen
(State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia)
Postfach 20 04 44
40102 Düsseldorf, Germany
Phone: +49 211 38424-0

14. Children

Lingly is not directed at children under 13, or under the minimum age that applies in your country. We do not knowingly collect data from children below that threshold.

15. Security

We rely on the security mechanisms of the platform: device encryption in iOS, „Sign in with Apple“, the private iCloud database and the permission system of the operating system. The app brings no encryption of its own and transmits nothing to servers of ours. No form of storage is completely secure, but keeping data on the device limits the risk considerably compared with a service in the cloud.

16. Changes

This policy may change, for instance when the app gains new features. The date above is then updated.
