Question 1

Can I upgrade later?

Accepted Answer

Yes – upgrades are flexible on two axes . You can switch to a higher plan (e.g. Sprachkurs → Sprachkurs + AI Pro ) and/or to a longer duration (e.g. 3 → 12 months) at any time. You only pay the price difference between your current bundle and the new one. Your progress, XP and vocabulary stay intact, and the upgrade activates immediately.

Question 2

Can I downgrade to a shorter plan?

Accepted Answer

No, downgrades are not available. Once you purchase a plan, you have access for the full duration. However, you can always learn at your own pace—there's no requirement to finish within the time frame. If you complete the course early, you'll still have access until your plan expires, giving you time to review and practice.

Question 3

What if I don't finish within my chosen duration?

Accepted Answer

No problem. If you need more time, upgrade to a longer duration within the same plan and pay only the price difference. After expiry you can also repurchase any bundle – your progress, XP and vocabulary are saved permanently and reattach automatically.

Question 4

Is this a subscription or one-time payment?

Accepted Answer

It's a one-time payment . You pay once and get full access to all 5 modules (72 units) for your chosen duration (3, 6 or 12 months). There are no recurring charges, no hidden fees, and no automatic renewals. After your access period ends, you can choose to repurchase if you want to continue learning.

Question 5

Do all plans include the same features?

Accepted Answer

No – and that's intentional. The four plans (Sprachkurs, AI Chat Standalone, Sprachkurs + AI, Sprachkurs + AI Pro) differ deliberately in what's included. Pick the bundle that fits how you want to learn:

Question 6

Can I get a refund?

Accepted Answer

I offer a 14-day money-back guarantee . If you're not satisfied within the first 14 days, contact me for a full refund—no questions asked. After 14 days, refunds are not available.

Question 7

What happens after my plan expires?

Accepted Answer

After your plan expires, you'll lose access to the course content, but your progress is saved permanently . If you repurchase any plan later, you'll pick up exactly where you left off—all completed units, XP, badges, and vocabulary progress will be restored.
