Terms of Service

Terms for using Nebulearn

Last updated September 6, 2025

These terms govern your use of Nebulearn, the AI-powered flashcard and spaced repetition study platform available at nebulearn.app. Nebulearn lets students generate AI flashcards from notes, PDFs, images, and audio, then study with FSRS, SM-2, or Leitner spaced repetition. By creating an account or using the service you agree to these terms in full. See also our Privacy Policy and pricing page.

What is Nebulearn?

Nebulearn is an AI-native, spaced-repetition learning platform that helps you create quizzes, flashcards, and study materials. You can generate questions from your content using AI, study with spaced repetition, and track your learning progress. By using our service, you agree to these terms.

Account Requirements

You must be at least 13 years old to use Nebulearn, as required by COPPA (Children's Online Privacy Protection Act). You need to provide accurate information when creating your account and keep your login credentials secure. Each person may only have one account.

How to Use Nebulearn

Please use Nebulearn responsibly and legally. Don't upload copyrighted content without permission, illegal material, or content that could harm others. Don't harass other users, attempt to break our service, or use it for cheating. Academic integrity matters — use Nebulearn as a study tool, not to complete assignments for you.

Your Content and Privacy

You own all the study materials you create on Nebulearn. We need permission to store, process, and display your content to provide our service, but we never share your personal study materials with others. We may use anonymized, aggregated data to improve Nebulearn, but your individual content remains private. You can export or delete your content anytime.

AI-Generated Content

Important: Nebulearn uses fine-tuned LLMs to generate questions and content. AI can make mistakes, provide inaccurate information, or misinterpret your materials. Always verify AI-generated content before using it for important academic work. Use AI content as a study aid and starting point, not as an authoritative source.

Premium Plans and Billing

Nebulearn offers free and premium plans. Premium subscriptions automatically renew monthly or yearly depending on your choice. You can cancel your subscription anytime from your account settings — cancellation takes effect at the end of your current billing period. All sales are final and no refunds are provided, except where required by law. The free tier remains available with basic features.

Service Changes and Updates

We continuously improve Nebulearn and may update features, pricing, or these terms. We'll notify you of significant changes via email or in-app notifications. Continued use of Nebulearn after changes means you accept the updates. We may temporarily suspend service for maintenance or updates.

Third-Party Services

Nebulearn uses various services to operate: Google Gemini API for AI features, Stripe for payment processing, and cloud hosting services. These providers have their own privacy policies and terms. We don't control third-party services and aren't responsible for their actions or policies.

Account Termination

We may suspend or terminate accounts that violate these terms, engage in illegal activities, or abuse our service. You can delete your account anytime from your settings — this permanently removes all your data. Download any content you want to keep before deleting your account, as this action cannot be undone.
