2. Purchasable products and prices follow in-app display as the source of truth. Unpublished or inactive products cannot be purchased.
3. QP and entitlements are not restored after account deletion.
4. Premium and QP are separate services. QP cannot be used to pay Premium fees. Purchasing Premium does not grant QP. Expiration of a Premium period does not cause loss of QP balance or of entitlements permanently obtained with QP.

2. Premium coverage includes learning courses published as Premium, corresponding Qlinx dictionaries, a wider Qurio AI usage quota than the free plan, and other features expressly marked as Premium in the app. What you can actually use follows the in-app display at that time. We do not promise that every future course, dictionary, or feature will be included.
3. Monthly and annual plans are available. Contract period, price, currency, and purchase conditions follow the purchase confirmation screens of this app and of the Apple App Store or Google Play.
4. Unless the user stops auto-renewal, Premium automatically renews for each selected contract period.
5. Payment, subscription status, and cancellation are managed in the Store used for the purchase.
6. After cancellation, you may continue to use Premium until the current paid period ends, subject to Store terms.
7. After the valid period ends, content and features that were available only because of Premium may again become restricted. Saved learning progress is retained. Entitlements permanently obtained with QP are not lost.
8. Deleting a Qlinx account does not mean cancellation of a subscription on the Apple App Store or Google Play.

10. Disputes about refunds, cancellation, and payment follow the terms of the relevant Store and applicable law.
11. Material changes will be announced by appropriate means as required by law and each Store's requirements.

Article 10 (Qurio AI)

1. Qurio AI is an information and learning-support feature that uses generative AI. Answers may contain errors, incomplete content, or content that is not up to date.
2. For medical, legal, administrative, safety, and other important decisions, users must also confirm with specialists, public authorities, official materials, or similar sources.
3. On Premium, Qurio AI may be used with a wider monthly quota than the free plan. The quota is not a fixed number of messages. Consumption depends on the question, input and output length, features used, and other processing volume, so the same number of uses may consume different amounts.
4. When the corresponding server feature is enabled, users may be able to check current usage in the app.
5. If the monthly quota is reached, new Qurio AI use may be restricted until the next reset.
6. We may change the calculation basis of quotas that apply to future periods, depending on the AI models used, features, provider terms, service stability, and other reasonable grounds. If there is a material change, we will give notice as required by law and each Store's terms.
7. All or part of Qurio AI may be temporarily unavailable due to outages, safety, fraud prevention, or other reasonable grounds.
8. In the initial release, Qurio AI add-on quota is not offered. Unlimited use is not promised.

3. After withdrawal, profile, progress, settings, QP, entitlements, etc. are deleted or anonymized and cannot be restored.
4. Even if you re-register using the same email address or authentication credentials, it is treated as a new account; past QP, progress, and entitlements are not carried over.
5. Internal records needed for purchases, refunds, fraud prevention, or audit may be retained for legal, accounting, or fraud response purposes but are not used to restore data after re-registration.
6. Deleting a Qlinx account does not mean cancellation of a subscription on the Apple App Store or Google Play. If you want to stop future renewals, manage or cancel in the Store used for the purchase before deletion.

Article 13 (Disclaimer)

1. We do not guarantee that the Service is free of defects, fit for a particular purpose, or continuously available.
