The legally binding terms for using Nebulearn
These Terms of Service (the "Terms") are a legally binding agreement between you and the operator of Nebulearn ("Nebulearn," "we," "us," or "our"). They apply to nebulearn.app, www.nebulearn.app, the Nebulearn iOS and Android apps, the Nebulearn Chrome extension, and any related websites, APIs, or features (together, the "Service").
By creating an account, clicking to accept, downloading the app or extension, or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.
If you use the Service on behalf of an organization (such as a school), you represent that you have authority to bind that organization, and "you" includes that organization.
Please also read Section 8 (AI), Section 16 (Disclaimers), and Section 17 (Limitation of liability). Those sections allocate risk and are essential to our ability to offer the Service.
Nebulearn is a study platform. It lets you create, import, generate, organize, share, and review flashcards and quizzes; use spaced-repetition and progress tracking; collaborate; and, where available, use AI features to help create or explain study materials.
We may offer free and paid plans, trials, storage add-ons, and other features. We do not promise that any particular feature will remain available, work without errors, or produce any academic result.
The Service is provided for personal study and teaching support. It is not a school, exam board, tutoring company, or professional advisory service.
You must be at least 13 years old to use the Service. This is required under the U.S. Children's Online Privacy Protection Act (COPPA) and similar laws. We do not knowingly provide the Service to children under 13.
If the law where you live requires a higher minimum age (for example, 16 in some countries in the European Economic Area), you must meet that higher age. If you are under 18 (or the age of majority where you live), you may use the Service only with the consent of a parent or legal guardian who agrees to these Terms on your behalf.
You represent that you meet these age requirements, that the information you provide is accurate, and that you have the legal capacity to enter this agreement (or that your parent or guardian does). We may suspend or delete accounts that we believe violate this section.
You may create an account with email and password, Google, or Sign in with Apple. You are responsible for your account, your credentials, and all activity under your account, whether or not you authorized it. Keep your password confidential. Notify us promptly if you believe your account has been compromised.
You must provide accurate account information (such as a valid email address) and keep it up to date. One person may not maintain multiple accounts to evade limits, bans, billing, or these Terms. We may refuse, reclaim, or require a change of usernames.
You can delete your account in Settings. Deletion is described in the Privacy Policy. Download anything you want to keep first. Deletion cannot be undone, and we are not responsible for content you fail to export.
You agree not to, and not to attempt to:
We may monitor for abuse, remove content, limit features, or suspend accounts at our discretion. We have no obligation to monitor the Service but may do so to operate, secure, and improve it, and to comply with law.
"User Content" means material you submit, upload, create, generate, or store through the Service. That includes flashcards, quizzes, folders, notes, photos, files, audio, selected webpage text, chat messages to the study tutor, profile information, and similar material.
You retain whatever ownership rights you already have in your User Content. These Terms do not transfer ownership of your original materials to us.
You grant Nebulearn a worldwide, non-exclusive, royalty-free license to host, store, process, transmit, display, reproduce, modify (for formatting, thumbnails, and technical operation), and otherwise use User Content solely as needed to operate, maintain, secure, and improve the Service, provide support, prevent abuse, and comply with law. That includes sending User Content to our AI and infrastructure providers (currently Google) when you use a feature that requires it. If you publish or share content, the license also includes making it available to the people you share with, and to the public if you publish it. This license does not let us use your private User Content to train our own machine-learning models.
You represent that you have all rights needed to submit User Content and to grant this license, and that your User Content does not infringe others' rights or violate law. You are solely responsible for User Content, including its accuracy, legality, and whether you are allowed to upload it (for example, copyrighted textbooks, lecture slides, or other people's notes).
We do not claim ownership of AI outputs generated for you, to the extent the law allows anyone to own them. Ownership of AI outputs is often legally uncertain. We do not warrant that outputs are unique, copyrightable, or non-infringing. Similar outputs may be generated for other users. You are responsible for how you use those outputs.
Folders can be private, shared with specific users, or published for others to browse and copy. Public profiles may show your username, avatar, bio, country, stats, and published decks. Likes, view counts, and similar activity may be visible.
If you publish or share content, other users may view, copy, export, and keep copies. Unpublishing or deleting later does not remove copies that others already made. Do not publish content you are not willing to make public.
We may remove, hide, or restrict public or shared content that we believe violates these Terms, law, or our operational needs, without liability to you.
Nebulearn uses third-party generative AI — currently Google's paid Gemini Developer API (Gemini models accessed with our server API key, not the consumer Gemini app) — to provide features such as question and flashcard generation, autofill, chat, audio transcription, distractors, the study tutor, and similar tools. Some image-occlusion processing may run on our servers (for example OCR) rather than Gemini.
When you use an AI feature, you instruct us to send the material needed for that request to Google. That can include text you paste or upload, files (such as PDFs and images), webpage text or snips captured by the extension, flashcard and quiz content, explanations, study stats, chat history, and photos attached to cards. Google processes that material under Google's Gemini API terms and privacy practices, which we do not control and which can change. We do not use your User Content to train our own machine-learning models.
Under Google's current Gemini API Additional Terms for Paid Services, Google states that it does not use prompts (including files and system instructions) or generated responses from paid API usage to improve Google products. Google may still log prompts and responses for a limited time to detect abuse, enforce its policies, and meet legal requirements, and may process data in countries where Google operates. If Google's terms change, or if API usage were ever billed as unpaid quota, Google's then-current terms would control. We intend to keep AI features on paid Gemini API usage.
AI output is unreliable. Models can invent facts, misread your materials, skip important details, give outdated or biased answers, and produce content that looks confident but is wrong. AI does not understand your course, syllabus, or exam the way a qualified human does.
You agree that:
To the maximum extent permitted by law, Nebulearn has no responsibility or liability for AI errors, omissions, hallucinations, bias, downtime, safety filters, lost generations, or any consequence of your relying on AI output.
The Service is a self-study aid. It does not provide educational credit, tutoring contracts, exam preparation guarantees, medical advice, legal advice, or professional advice of any kind. Spaced-repetition scheduling, ELO-style ratings, streaks, mastery estimates, and similar metrics are approximations only. They are not proof of knowledge and are not a substitute for your own judgment or your instructors.
We do not warrant that using Nebulearn will improve your grades, help you pass an exam, get you into a program, or produce any particular learning outcome. You are solely responsible for your academic integrity and for complying with your school's rules on AI and study aids.
The Service — including software, design, trademarks, official Nebulearn decks, documentation, and branding — is owned by us or our licensors. We grant you a limited, revocable, non-exclusive, non-transferable license to use the Service for your personal or internal educational use in accordance with these Terms. No other license is granted.
If you send ideas, suggestions, or feedback, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use them without restriction or compensation.
We may offer a free plan and paid plans (currently including Premium and Platinum) billed monthly or yearly, plus optional add-ons such as storage boosts. Features, limits, and prices can change. Displayed prices may exclude applicable taxes.
Eligible users may receive a free trial (currently 14 days where offered). Unless you cancel before the trial ends, the paid subscription begins and you will be charged. We may limit trial eligibility (for example, one trial per person or payment method).
Paid subscriptions automatically renew until you cancel. Cancel anytime from account settings (web/Stripe) or from your Apple or Google subscription management (mobile). Cancellation takes effect at the end of the current paid period unless the store or applicable law says otherwise. You keep paid features until then. We do not provide prorated refunds except where required by law or by Apple or Google.
For App Store purchases: payment will be charged to your Apple ID account at confirmation of purchase. The subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period, at the price shown at purchase. Manage or turn off auto-renewal in Settings → Apple ID → Subscriptions. Any unused portion of a free trial period will be forfeited if you purchase a subscription. Restore previous purchases with the Restore control on the paywall.
Web purchases are processed by Stripe. iOS and Android in-app purchases are processed by Apple or Google through RevenueCat. We do not receive or store full payment card numbers.
Except where required by law or by Apple's or Google's refund rules, fees are non-refundable, including unused time, unused AI credits, and accidental purchases. For App Store or Google Play purchases, you must request refunds from Apple or Google; we cannot process those refunds ourselves. Statutory cooling-off or consumer-cancellation rights (for example in the EU/UK or under certain Canadian provincial laws) apply where they cannot be waived.
If a payment fails, is reversed, or is charged back, we may suspend paid features. You remain responsible for amounts owed and for any fees we reasonably incur because of a chargeback you are not entitled to.
If you download the iOS or Android app, Apple's or Google's terms also apply. In a conflict about how store billing works, the store's terms control that billing relationship. Additional Apple-required terms are in Section 24.
The Chrome extension can read page content you choose to capture (such as selected text or a screen snip) and send it to Nebulearn, including to AI features. It may also store local preferences and authentication tokens in browser storage. You are responsible for not capturing confidential, illegal, or infringing material from websites you visit. Some sites prohibit scraping or copying; you must respect those rules and applicable law.
The Service depends on third parties, including Google (sign-in, paid Gemini Developer API, Analytics, ads, reCAPTCHA), Apple, Stripe, RevenueCat, Amazon Web Services, MongoDB Atlas, hosting providers, Formspree (contact form), and others listed in the Privacy Policy. Their terms and privacy policies apply to their processing. We are not responsible for third-party outages, errors, security incidents, policy changes, or content.
Links to third-party sites are provided for convenience only. We do not endorse and are not responsible for those sites.
We provide the Service as is and as available. We do not guarantee uptime, backup completeness, or that data will never be lost. You should export important materials.
We may change, suspend, or discontinue any part of the Service, including AI models, plan limits, and pricing. We may perform maintenance that causes downtime. We may offer experimental or beta features that can be unstable or withdrawn.
We may update these Terms. We will change the "Last updated" date and, for material changes, we may provide additional notice (for example email or an in-app message). If you continue using the Service after the updated Terms take effect, you accept them. If you do not agree, stop using the Service and delete your account.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE AND ALL CONTENT (INCLUDING AI-GENERATED CONTENT) ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. THAT INCLUDES IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, ACCURACY, AND NON-INFRINGEMENT.
WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, ERROR-FREE, OR FREE OF HARMFUL COMPONENTS; THAT DATA WILL NOT BE LOST; THAT AI OUTPUT OR STUDY MATERIALS WILL BE ACCURATE, COMPLETE, OR APPROPRIATE FOR YOUR COURSE; OR THAT DEFECTS WILL BE CORRECTED.
YOU USE THE SERVICE AND RELY ON ANY CONTENT AT YOUR SOLE RISK.
Some places do not allow certain warranty disclaimers. In those places, we disclaim warranties only to the fullest extent the law allows. If you are a consumer, you may have non-excludable statutory guarantees (for example under Canadian provincial consumer law, Quebec's Consumer Protection Act, EU/UK consumer law, or the Australian Consumer Law). Those rights are not excluded.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEBULEARN AND ITS OPERATORS, OWNERS, AFFILIATES, LICENSORS, AND SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, BUSINESS, OR ANTICIPATED SAVINGS, EVEN IF WE WERE ADVISED THAT SUCH DAMAGES WERE POSSIBLE.
WITHOUT LIMITING THE ABOVE, WE ARE NOT LIABLE FOR DAMAGES ARISING OUT OF OR RELATED TO:
TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE OR THESE TERMS, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR OTHERWISE, WILL NOT EXCEED THE GREATER OF (A) CAD $50 OR (B) THE AMOUNTS YOU PAID TO US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE CLAIM. IF YOU HAVE ONLY USED THE FREE PLAN AND PAID US NOTHING, OUR TOTAL LIABILITY IS LIMITED TO CAD $50.
THESE LIMITATIONS ARE A FUNDAMENTAL PART OF THE BARGAIN AND APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE.
What we cannot disclaim. Nothing in these Terms excludes or limits liability that cannot be excluded under applicable law, including liability for fraud or fraudulent misrepresentation, or for death or personal injury caused by negligence where such exclusion is prohibited. If you are a consumer, nothing limits your non-waivable statutory rights. If a court finds a limitation unenforceable as to you, it will be modified to the minimum extent needed to make it enforceable.
To the maximum extent permitted by law, you will defend, indemnify, and hold harmless Nebulearn and its operators, owners, affiliates, and suppliers from any claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to: (a) your User Content; (b) your use of the Service, including AI features; (c) your violation of these Terms or of law; (d) your infringement of someone else's rights; or (e) disputes between you and another user, school, or third party. We may assume exclusive defense of any matter, and you will cooperate. This section does not apply to the extent a claim is caused by our willful misconduct or to the extent indemnification is prohibited for consumers in your jurisdiction.
You may stop using the Service and delete your account at any time. We may suspend or terminate access immediately if we believe you violated these Terms, create risk or legal exposure, fail to pay, or if we discontinue the Service.
On termination, your license ends. We may delete your data as described in the Privacy Policy. Sections that by their nature should survive (including 5–10, 14–24, and the AI, disclaimer, liability, and indemnity sections) will survive.
If you believe content on the Service infringes your copyright, email nebulearn.app@gmail.com with: a description of the work; the URL or location of the allegedly infringing material; your contact information; a statement that you have a good-faith belief the use is not authorized; a statement under penalty of perjury that your notice is accurate and that you are the owner or authorized to act; and your physical or electronic signature.
We may remove content and, in appropriate circumstances, terminate repeat infringers. If your content was removed and you believe that was a mistake, you may send a counter-notice to the same address with the information the law requires.
These Terms are governed by the laws of Canada and of the Canadian province or territory in which the operator of Nebulearn is established, without regard to conflict-of-law rules, except that the UN Convention on Contracts for the International Sale of Goods does not apply.
Subject to the consumer-rights paragraph below, the courts of that province or territory will have exclusive jurisdiction over disputes, except that we may seek injunctive or equivalent relief in any jurisdiction to protect our intellectual property or the Service.
If you are a consumer, you may bring claims in your home courts where mandatory law gives you that right (including in Quebec under the Consumer Protection Act, and in the EEA/UK under consumer protection law). Nothing in these Terms requires you to waive a non-waivable right to participate in a class or representative proceeding where such a waiver is prohibited.
You and we will try to resolve disputes informally first by emailing nebulearn.app@gmail.com. You agree to describe the issue in good faith so we have a chance to resolve it.
Questions about these Terms: email us. For privacy-specific requests, see the Privacy Policy.

If you use the Service as an iOS app obtained from Apple, the following terms apply and control if they conflict with the rest of these Terms solely as required by Apple:
