Effective Date: 2026.07.23.
These Terms of Service ("Terms") are a legally binding agreement between you ("User", "you") and Marton Greber ("Company", "we", "us", "our"). They govern your access to and use of any mobile software applications that we develop and publish (each, an "App", and collectively, the "Apps") and any related websites, products, or services (together with the Apps, the "Service"). By downloading, installing, or using any part of the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.
Your use of an App is also subject to the terms and usage rules of the platform from which you obtained it (the "Store"). For Apps obtained through Apple’s App Store, Apple’s Standard Licensed Application End User License Agreement ("Standard EULA") applies unless a valid custom end-user license agreement is provided through Apple. For Apps obtained through Google Play, your use of Google Play is also subject to the Google Play Terms of Service. These Terms supplement the applicable Store terms and, where applicable, the Standard EULA. If these Terms conflict with mandatory Store terms or the Standard EULA, those terms control to the extent of the conflict.
You must be legally capable of entering into these Terms. If you are under the age of legal majority where you live, you may use the Service only with the permission and supervision of a parent or legal guardian who agrees to these Terms on your behalf.
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download, install, and use the Apps on devices you own or control for your personal, non-commercial use, as permitted by the applicable Store usage rules. Where enabled by the Store, an App may also be accessed through Family Sharing or similar Store-provided functionality. You agree not to:
Unless an App expressly states otherwise, information you enter into an App, such as SQL queries, exercise answers, progress, or preferences, remains on your device. We do not claim ownership of these inputs.
Some features may let you copy information to the clipboard, open an external website, or share information using your device’s share controls. Information from these optional copy and share features is provided to an external service only when you choose to provide or share it. Your use of that external service, including any artificial-intelligence service, is governed by the external provider’s own terms and privacy policy.
Certain features of our Apps may require an in-app purchase or subscription through the applicable Store, such as the Apple App Store or Google Play Store. The product, subscription period, current price, included features, and any introductory offer or free trial are displayed before you confirm a purchase.
Payments are charged to your Store account when you confirm the purchase. Auto-renewable subscriptions renew for the displayed subscription period unless you cancel them through your Store account settings before the renewal deadline specified by the Store. The Store may charge your account shortly before the current subscription period ends. Deleting an App does not cancel a subscription.
You can manage or cancel a subscription through your Apple Account or Google Play account settings. Cancellation takes effect at the end of the current paid period unless the Store states otherwise, and you will continue to have access to the subscribed features until then. Where offered, an unused portion of a free trial may be forfeited when you purchase a subscription, subject to applicable Store rules.
Eligible purchases can be restored using the Restore Purchases option provided in the App. Billing, cancellation, price changes, refunds, and payment disputes are handled by the applicable Store under its rules. Nothing in these Terms limits refund or cancellation rights that cannot legally be waived.
The Service, including all content, graphics, code, and software, is owned by the Company or its licensors and is protected by intellectual-property laws. All trademarks, service marks, and logos are the property of their respective owners.
The Service may contain links to or integrate with third-party websites or services, including Store services, subscription-management providers, sharing tools, and optional external artificial-intelligence services. We do not control those services. Your use of them is subject to their terms and privacy policies. To the extent permitted by law, we are not responsible for the availability, content, or independent practices of third-party services.
We may suspend or terminate your access to the Service if you materially violate these Terms, misuse the Service, or if suspension is reasonably necessary to protect the Service, other users, or comply with law. Where reasonably practical, we will provide notice. Termination of access does not automatically cancel a Store subscription; subscriptions must be managed through the applicable Store. Any rights that must survive termination by their nature or under applicable law will continue to apply.
To the fullest extent permitted by law, the Service is provided on an "AS IS" and "AS AVAILABLE" basis, without warranties of any kind, whether express, implied, or statutory, including warranties of merchantability, satisfactory quality, fitness for a particular purpose, and non-infringement. We do not guarantee that the Service will be uninterrupted, secure, or error-free. Nothing in these Terms excludes warranties, remedies, or consumer rights that cannot legally be excluded.
To the fullest extent permitted by law, the Company and its affiliates, directors, employees, and agents shall not be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, data, use, goodwill, or other intangible losses arising out of or in connection with the Service. To the fullest extent permitted by law, our aggregate liability will not exceed the greater of (a) the total amount you paid us for the Service in the twelve (12) months preceding the claim or (b) USD 50.
Nothing in these Terms limits or excludes liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, gross negligence or willful misconduct where applicable, or any other liability or consumer remedy that cannot legally be limited or excluded.
To the extent permitted by applicable law, you agree to indemnify the Company against third-party claims, damages, and reasonable costs arising directly from your unlawful use of the Service, your material violation of these Terms, or your infringement of another person’s rights. This section does not apply to the extent a claim results from our own acts or omissions and does not limit rights that cannot legally be waived.
These Terms are governed by the laws of Hungary, without regard to conflict-of-law principles. If you are a consumer, this choice of law does not deprive you of mandatory protections provided by the laws of your country of residence, and you may bring a claim in any court available to you under applicable consumer law. Where the Standard EULA applies, its governing-law and jurisdiction provisions also apply as stated there.
We may update these Terms to reflect changes to the Service, Store requirements, or applicable law. We will post the revised Terms and update the Effective Date above. Where required by law, we will provide reasonable notice of material changes. Changes apply prospectively from their effective date and do not reduce rights already acquired through a completed purchase or subscription period.
