These Terms of Use (“Terms”) govern your use of the TextbookAI mobile application (“App”) operated by Daniel Alblas (“we,” “us,” or “our”). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.
TextbookAI is an AI-powered study tool that allows users to upload PDF documents and interact with their content through a conversational chat interface. The App uses artificial intelligence to generate responses based on the content of your uploaded documents.
You must be at least 13 years of age to use the App. If you are under 18, you must have permission from a parent or legal guardian. By using the App, you represent that you meet these requirements.
You must create an account to use the App. You may register using an email address and password or through Google Sign-In. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You agree to notify us immediately of any unauthorized use of your account.
The App offers the following subscription tiers:
Subscriptions are billed through your Apple ID account. Payment is charged at confirmation of purchase. Prices are in U.S. dollars and may vary by region.
Subscriptions automatically renew unless canceled at least 24 hours before the end of the current billing period. Your account will be charged for renewal within 24 hours prior to the end of the current period at the same rate.
You can manage or cancel your subscription at any time through your Apple ID account settings (Settings > Apple ID > Subscriptions). Cancellation takes effect at the end of the current billing period. No refunds are provided for partial billing periods.
We may change subscription prices from time to time. Price changes will take effect at the start of the next billing period following notice to you. Your continued use of the App after a price change constitutes your agreement to the new price.
You agree not to:
You retain all ownership rights to the PDF documents you upload (“User Content”). By uploading documents, you grant us a limited, non-exclusive license to process, store, and analyze your content solely for the purpose of providing the App’s services to you.
You are solely responsible for ensuring you have the right to upload and use any documents with the App. We do not claim ownership of your uploaded content and will not share your documents with other users.
We reserve the right to remove any content that violates these Terms without prior notice.
The App uses artificial intelligence to generate responses based on your uploaded documents. AI-generated responses may contain errors, omissions, or inaccuracies. Responses are provided for informational and study purposes only.
AI-generated responses do not constitute academic, legal, medical, financial, or any other form of professional advice. You should independently verify any information provided by the App before relying on it.
You are responsible for using the App in compliance with your educational institution’s academic integrity policies. The App is intended as a study aid, not a tool for academic dishonesty.
The App, including its design, features, code, and branding, is owned by us and protected by intellectual property laws. These Terms do not grant you any right to use our trademarks, logos, or branding.
Your use of the App is also governed by our Privacy Policy, which describes how we collect, use, and protect your personal information. By using the App, you consent to the practices described in the Privacy Policy.
THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ANY DEFECTS WILL BE CORRECTED.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE APP, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
OUR TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING FROM OR RELATED TO THE APP SHALL NOT EXCEED THE AMOUNT YOU PAID TO US IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM.
You agree to indemnify and hold us harmless from any claims, damages, losses, or expenses (including reasonable attorney’s fees) arising from your use of the App, your violation of these Terms, or your infringement of any third-party rights.
We may suspend or terminate your access to the App at any time, with or without cause, and with or without notice. Upon termination, your right to use the App ceases immediately. Provisions that by their nature should survive termination (including Disclaimers, Limitation of Liability, and Indemnification) shall survive.
You may delete your account at any time through the App’s settings. Upon account deletion, your uploaded documents and chat history will be permanently removed.
We may update these Terms from time to time. We will notify you of material changes by posting the updated Terms within the App or by other reasonable means. Your continued use of the App after changes are posted constitutes your acceptance of the revised Terms.
These Terms shall be governed by and construed in accordance with the laws of the United States, without regard to conflict of law principles.
