The Platform enables paying subscribers to upload documents (e.g., PDFs) and generate interactive quizzes using artificial‑intelligence technology to help them learn and memorise the documents' content. The Service is provided online; no physical goods are shipped.
At DataRiver OÜ, we are committed to delivering a valuable and effective learning experience through our AI-powered quiz generation platform. This policy outlines our guidelines regarding refunds and dispute resolutions.
Our services are subscription-based and commence immediately upon purchase. Due to the nature of our digital services and the computational resources involved, we generally do not offer refunds once a subscription period has started.
However, we understand that exceptional circumstances may arise. If you believe you were charged in error or are experiencing technical issues that prevent you from using the service effectively, please contact us within 7 days of the charge. We will review your case and may issue a full or partial refund at our discretion.
To request a refund, please email us at [email protected] with the following details:
If you have concerns or disputes regarding a charge, we encourage you to contact us directly before initiating a chargeback. Most issues can be resolved promptly through our support team.
In the event of a dispute, we are committed to resolving the matter amicably and fairly. We reserve the right to suspend accounts that file unfounded or fraudulent disputes.
We aim to respond to all inquiries within 2 business days.
All trademarks, logos, software, and other intellectual property on the Platform are owned by the Company or its licensors. You may not copy, modify, distribute, sell, or lease any part of the Service or included software.
Your personal data is processed in accordance with our Privacy Notice and in compliance with the EU General Data Protection Regulation (GDPR). We act as a data controller for Account data and as a data processor for Content you upload. A Data Processing Agreement (DPA) is available upon request.
You agree not to:
The Service is provided “as is” and “as available” without warranties of any kind. We do not warrant that the Service will be uninterrupted, error‑free, or meet your expectations. Some jurisdictions do not allow exclusion of implied warranties; the above exclusion may not apply to you.
To the maximum extent permitted by law, our total liability arising out of or relating to these Terms or the Service will not exceed the amount you paid to us in the 12 months preceding the event giving rise to the claim. We are not liable for indirect, incidental, special, or consequential damages.
You agree to indemnify and hold us harmless from any claims, damages, or expenses (including legal fees) arising from your breach of these Terms or misuse of the Service.
We may suspend or terminate your Account immediately upon notice if you breach these Terms, misuse the Service, or if required by law. Upon termination, your right to use the Service ends immediately, and Sections 10–18 survive.
We may update these Terms from time to time. We will notify you by email or via the Platform at least 14 days before changes take effect. Continued use of the Service after the effective date constitutes acceptance of the revised Terms.
