Last updated: April 29, 2026

1. Acceptance of terms

By using the Vokki app, you agree to these Terms of Use. If you do not agree to the terms, please stop using the app.

2. Service description

Vokki is a mobile application for learning German. The app includes: a library of stories with parallel text and synchronized audio, a structured German language course with exercises, word memorization trainers (translation, constructor, listening, sprint, and others), vocabulary flashcards with spaced repetition.

3. Account and trial period

You can use the app without an account — all data will be stored only on the device.

To sync progress between devices, you can sign in with Apple or Google. Upon signing in, an account is created and your learning progress is stored on the server.

You can delete your account and all server data at any time through settings.

The app may provide a free trial period from the first launch. After it ends, access to content may be limited.

4. Content and copyright

All app content (texts, audio, images) is the property of the developer or used under license. Copying, distribution, or commercial use of the content without written permission is prohibited.

5. Limitation of liability

The app is provided "as is". We do not guarantee that the app will work without interruptions or errors. We are not liable for any damages related to the use of the app.

6. Changes to terms

We reserve the right to change these Terms of Use. We will notify you of significant changes through app updates.

8. Subscriptions and payments

Vokki offers paid auto-renewable subscriptions (Starter, Pro, Ultra). The subscription term is one month and renews automatically until cancelled. Pricing is shown inside the app and on the App Store and Google Play listings.

Payments are processed by Apple App Store or Google Play. Vokki does not receive or store your payment card data. To cancel a subscription, open Settings → Apple ID → Subscriptions on iOS, or Google Play → Subscriptions on Android, and cancel before the next renewal date.

Refunds are handled by Apple or Google according to their respective policies; Vokki cannot issue refunds directly.

After cancellation, paid features become unavailable at the end of the current paid period. All learning data (progress, vocabulary, custom content) remains preserved.
