Terms of Service

1. Acceptance

By downloading, accessing, or using the Klartakt app ("the App"), you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the App. Apple's own Licensed Application End User License Agreement also applies in addition to these Terms.

2. The service

Klartakt provides German-language learning features, including spaced-repetition flashcards, grammar lessons, a dictionary, exam-vocabulary tracks, an AI conversation partner, and classroom/social features. We may add, change, or remove features over time.

3. Your account, and use by younger learners

• You must provide accurate information and keep your credentials secure. You are responsible for activity under your account.
• To create your own account you must be at least 16, the age of digital consent in Germany (GDPR Art. 8).
• Younger learners are welcome. Children under 16 may use Klartakt under the account and supervision of a parent, legal guardian, or teacher — for example as a member of a class created by their teacher. That adult is responsible for accepting these Terms, for any consent required under applicable data-protection law, and for supervising the child's use of the app (including the AI conversation feature and the social/classroom features).
• Klartakt is not designed or marketed as a service directed at children, and we do not knowingly allow children under 16 to register their own accounts.

4. Licence to use the App

We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the App and its content for your own personal, non-commercial language learning. This licence does not transfer any ownership to you.

5. Things you may NOT do

You agree not to:

• copy, distribute, publicly display, sell, rent, sublicense, or otherwise exploit the App or its content;
• scrape, bulk-export, harvest, or extract the vocabulary/grammar catalogue or any substantial part of it, by manual or automated means;
• use the App or its content to train, fine-tune, or ground any AI / machine-learning model or dataset;
• reverse engineer, decompile, or disassemble the App, except where such restriction is prohibited by law;
• circumvent usage limits, entitlements, or security measures;
• upload unlawful, infringing, harmful, or abusive content; or
• misuse the classroom or social features (harassment, impersonation, or sharing others' data without permission).

6. Subscriptions and payments

• Klartakt offers a free tier and an optional Pro subscription (currently $3.99/month, $29.99/year, or $69.99 one-time "lifetime" — prices may vary by region and over time).
• Who you are buying from. All purchases are made as in-app purchases through the Apple App Store (and Google Play once launched). For these purchases Apple is the seller/merchant of record — in the EU, Apple Distribution International Ltd., Ireland. The purchase contract is therefore concluded between you and Apple and is governed by Apple's Media Services Terms and Conditions. We never receive or process your payment details.
• Cancellation, refunds and your right of withdrawal. Because Apple is the seller, cancellations, refunds and any statutory right of withdrawal are handled by Apple through your app-store account, under Apple's terms and applicable consumer law. Subscriptions auto-renew unless cancelled at least 24 hours before the current period ends. Your statutory consumer rights against Apple are not affected by these Terms.
• The "lifetime" option grants access for the lifetime of the product/service, not a personal lifetime guarantee.
• Purchases by minors. If you are under 18, you may only make a purchase with the permission of a parent or legal guardian. Apple's Family Sharing / "Ask to Buy" controls can be used to manage this.

7. User-generated content

You retain ownership of content you create (e.g. custom cards). You grant us a licence to host, store, sync, and display it as needed to operate the service. You are responsible for the legality of content you upload and must have the rights to it.

8. Our intellectual property

The App, its source code, content catalogue, audio, designs, the "Klartakt" name, and the logo are owned by Maryam Rabiee and protected by law. Nothing here grants you rights to our trademarks.

9. Exam names and third parties

10. Third-party content

The App uses third-party components under their own licences (e.g. dictionary data from Wiktionary under CC BY-SA with attribution; fonts under the SIL Open Font Licence; licensed animation assets). Your use of those is also subject to their terms.

11. Availability, disclaimers

The App is provided "as is" and "as available". We do not warrant that it will be uninterrupted or error-free, or that particular learning outcomes or exam results will be achieved. Statutory warranty rights for consumers remain unaffected.

12. Limitation of liability

We are liable without limitation for damages caused intentionally or by gross negligence, and for injury to life, body, or health. For slight negligence we are liable only for breach of a material contractual obligation, and limited to the foreseeable damage typical for this type of contract. Liability under the German Product Liability Act remains unaffected.

13. Suspension and termination

We may suspend or terminate access for breach of these Terms. You may stop using the App and delete your account at any time (Settings → Account).

14. Changes to these Terms

We may update these Terms; the updated version will be posted here with a new effective date, and we will notify you of material changes where required.

15. Governing law and disputes

These Terms are governed by the laws of the Federal Republic of Germany, without prejudice to mandatory consumer-protection rules in your country of residence. The European Commission provides an online dispute-resolution platform at ec.europa.eu/consumers/odr. We are neither willing nor obliged to participate in dispute-resolution proceedings before a consumer arbitration board.
