Oktopus1. Scope
These terms of use apply to the Oktopus app and all of its features. By tapping “Agree” you accept them. Without agreeing you cannot use the app.
2. What Oktopus is
Oktopus is an independent practice program for German exams from A1 to C2 and for special exams (integration, nursing, medicine, university). All tasks are our own exercises in the format of these exams; the exam patterns carry no names, and Oktopus has no connection with any examination body. Oktopus is not an official exam or an examination body and does not issue certificates. Results in the app are estimates for practice; passing the real exam is not guaranteed. The exam radar is based on our own analysis of practice material, not on official statistics.
3. Your account
You need an account to use the app. Your details must be accurate and you must keep your login secret; the account is for you alone. You must be at least 16 years old or have the consent of your parents. You can delete your account in the app at any time.
4. AI features
Some features use artificial intelligence (Google Cloud AI services), such as grading writing and speaking or generated exercises. Results may contain mistakes and do not replace an official assessment. Your texts and recordings are sent to the AI service for this. Speaking recordings are deleted automatically after a fixed period (currently 30 days); you can delete them yourself earlier. The voices of the listening texts are generated by AI and are not recordings of real people.
5. Plans, credits and purchases
The FREE plan costs nothing and shows ads. Subscriptions (such as PLUS) remove the ads and include credits for AI features. Credit packs can only be bought with PLUS or higher. Purchases go through the App Store or Google Play; their terms apply, and that is where you renew or cancel subscriptions. How many credits an AI feature uses is not fixed: for features charged by use (such as gradings, conversations and the assistant) it depends on the size of the request (length of the text or recording, length of the answer, exam level). The app shows the price before running a feature; for features charged by use, a maximum is held, never more is charged, and the rest goes back to your balance. Credit prices may change when the costs of the AI services change. A plan's monthly credits expire at the next renewal; purchased credits do not expire while the account exists. Credits have no cash value and cannot be transferred. Your statutory rights remain unaffected.
6. Dictionary
The dictionary is free on every plan. Its entries come from Wiktionary and are licensed under CC BY-SA 4.0. Where no Arabic translation was available, it was machine-made and is marked as such. We do not guarantee that entries are complete or correct.
7. Rules of use
Use Oktopus for your own learning only. You may not manipulate the app or extract its content automatically, resell or publish content, upload unlawful or offensive content, or share your account with others. If you break these rules we may suspend the account.
8. Rights to the content
The tasks, recordings, texts and design of the app belong to us or our licensors. You may use them in the app for your own learning. The dictionary data is licensed under CC BY-SA 4.0.
9. Liability
We are fully liable for intent and gross negligence and for injury to life, body or health. For slight negligence we are liable only for breaches of essential obligations and only for foreseeable, typical damage. We aim to keep the app available at all times but cannot guarantee it.
10. Changes
We may change these terms, for example when features or laws change. For material changes the app will ask for your consent again.
11. Final provisions
German law applies. Mandatory consumer protection rules of the country you live in remain unaffected. If a provision is invalid, the others remain valid. The German version is binding; the Arabic and English versions are for understanding only.
