Our full Privacy Policy lives at https://www.calculusedge.com/privacy.Calculus Edge is committed to handling user data, including Google user data, in a transparent and limited manner. The disclosures in this section are duplicated here, in full, so that any reviewer or visitor reading this Terms of Service page can confirm how the Platform interacts with Google user data.
Calculus Edge offers Google Sign In as one optional authentication method. When you choose to sign in with Google, the Platform receives only the data attached to the standard OAuth scopes openid, email, and profile. Specifically, we receive:
sub claim)We do not request, access, store, or use any restricted or sensitive Google scopes. Calculus Edge does not access Gmail, Calendar, Drive, Contacts, Photos, YouTube, or any other Google service data. We never read, write, or otherwise interact with content stored in your Google account.
Our use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Google user data is not sold, rented, leased, shared with advertisers, or transferred to data brokers. The only third parties that receive any portion of authentication data are infrastructure providers acting as data processors on our behalf, listed in Section 7 of the Privacy Policy. Specifically:
Google user data is never shared with our artificial intelligence providers (Anthropic, OpenAI, and Google Gemini when used for AI processing), with Stripe (payment processor), with Resend (transactional email), or with any other third party. AI providers process only the study materials you choose to upload to the AI Study Guide, never your Google account profile data.
Questions, concerns, or requests regarding Google user data, privacy, or any other matter covered by this disclosure can be sent to calculusedge@gmail.com.

The full Privacy Policy with additional detail (cookies, international transfers, California and EU and UK resident rights, children's privacy, and more) is at https://www.calculusedge.com/privacy.
These Terms of Service (the "Terms") form a legally binding agreement between you ("you," the "user," or the "customer") and Calculus Edge, a sole proprietorship of Andrew Finkelstein based in the Commonwealth of Virginia, United States ("Calculus Edge," "we," "us," or "our"), governing your access to and use of the website located at https://www.calculusedge.com and our related products and services (collectively, the "Platform").
By creating an account, purchasing a product, booking a session, or otherwise accessing or using any part of the Platform, you represent that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree to these Terms, you may not use the Platform.
You also represent that you are at least 18 years of age, or that you are between the ages of 13 and 17 and have obtained the consent of a parent or legal guardian to enter into these Terms. The Platform is not directed to children under the age of 13.
Calculus Edge offers the following products and services:
We may modify, add, suspend, or discontinue any portion of the Platform at any time. Where a material change adversely affects access to a product you have already purchased, we will make reasonable efforts to give you notice and a refund or comparable substitute as required by law.
Some features of the Platform require an account. You agree to provide accurate, current, and complete information when creating an account and to keep your information current. You are responsible for maintaining the confidentiality of your credentials and for all activity that occurs under your account. Notify us immediately at calculusedge@gmail.comif you become aware of any unauthorized access. We reserve the right to suspend or terminate any account that violates these Terms or that we reasonably believe has been compromised.
You agree not to share your account credentials or to transfer your account to another person. Each account is for the sole use of the individual who created it.
All prices are listed in United States dollars. Payments are processed by Stripe, our third party payment processor. By providing payment information, you represent that you are authorized to use the payment method and you authorize us, through Stripe, to charge the amount listed at the time of purchase, including any applicable taxes and fees.
Course purchases grant lifetime access to the content as it exists at the time of purchase. Tutoring packages must be redeemed within the time window stated at the time of purchase (and absent such a stated window, within twelve months of purchase). Subscriptions to the AI Study Guide renew automatically at the end of each billing period unless cancelled before the renewal date. You may cancel a subscription at any time through your account settings or by emailing us. Cancellation takes effect at the end of the current billing period and does not entitle you to a refund of fees already paid for that period.
Refunds. Course purchases are eligible for a refund within fourteen (14) days of purchase, provided that you have not consumed more than 20 percent of the course content. Tutoring sessions that have not yet been used are refundable within fourteen (14) days of purchase, less any non recoverable processing fees. Sessions that have been booked but cancelled less than 24 hours before the scheduled start time are not refundable. Subscription fees are non refundable except where required by law. To request a refund, email calculusedge@gmail.com within the applicable window.
Tutoring sessions are scheduled through Cal.com. By booking a session, you agree to be present and prepared at the scheduled time and to participate in good faith. Sessions are non transferable to third parties without our prior written consent. Late cancellations (less than 24 hours before the scheduled start time) may forfeit the session credit at our discretion. We will use reasonable efforts to reschedule if you give us at least 24 hours of advance notice.
Tutoring is provided on a best effort, professional basis. We do not guarantee any specific grade, score, course outcome, or educational result. Educational outcomes depend on many factors outside of our control, including but not limited to student preparation, engagement, prior knowledge, study habits, course instructor and curriculum, exam conditions, and individual circumstances.
The AI Study Guide processes materials you upload using third party artificial intelligence providers (currently Anthropic and OpenAI) to generate personalized study output such as memorization items, exercises, strategies, and practice exams. You represent and warrant that you have the right to upload each item you submit and that doing so does not infringe the intellectual property rights, privacy rights, or other rights of any third party.
You retain ownership of the original materials you upload. You grant Calculus Edge a worldwide, non exclusive, royalty free license to host, store, transmit, process, and display your uploaded content, and to create derivative outputs from it, solely for the purpose of providing the AI Study Guide to you and operating, securing, and improving the Platform. This license terminates with respect to your uploaded content when you delete it from the Platform or close your account, except for residual copies that may persist in our backups for the retention period described in our Privacy Policy.
Generated study output is provided to assist your learning. It may contain inaccuracies, omissions, or errors, and should not be relied upon as the sole source of truth. You are responsible for verifying the accuracy of any generated content before relying on it in academic, professional, or other consequential settings. We expressly disclaim any responsibility for the accuracy of AI generated output. Use of the AI Study Guide for academic dishonesty, exam cheating, or violation of your institution's academic integrity policies is prohibited and may result in termination of your account.
All course videos, written course materials, branding, logos, the Platform's design and user interface, prompts, the AI Study Guide methodology, and all related intellectual property are the exclusive property of Calculus Edge and are protected by United States and international copyright, trademark, and other intellectual property laws.
Upon purchase, you receive a limited, personal, non exclusive, non transferable, non sublicensable, revocable license to access and view the purchased course content for your own personal and non commercial educational use. You may not reproduce, distribute, modify, publicly display, publicly perform, transmit, scrape, download (other than through tools we provide), record, screenshot, sell, resell, or create derivative works of any course content or other Platform materials without our prior express written consent.
Any feedback, suggestions, or ideas you provide to us regarding the Platform may be used by us without compensation to you and without any obligation to you.
You agree that you will not, and will not permit any third party to:
We may, at our sole discretion and without liability, suspend or terminate access for any user we reasonably believe has violated this section.
The Platform integrates with or links to third party services, including Stripe (payments), Supabase (hosting), Anthropic and OpenAI (AI), Cal.com (scheduling), Vercel (hosting), Resend (email), and Google (sign in). These services are operated by their respective providers under their own terms and privacy policies, which you should review. We are not responsible for the acts, omissions, content, or practices of any third party service. Your use of a third party service is subject to its terms.
THE PLATFORM IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS, WITHOUT ANY WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, CALCULUS EDGE DISCLAIMS ALL WARRANTIES, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON INFRINGEMENT, AND ANY WARRANTIES ARISING FROM A COURSE OF DEALING, USAGE, OR TRADE PRACTICE.
WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT THE PLATFORM WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR FREE, THAT THE INFORMATION OR CONTENT (INCLUDING AI GENERATED OUTPUT) ON THE PLATFORM IS ACCURATE, COMPLETE, OR RELIABLE, THAT THE PLATFORM WILL MEET YOUR REQUIREMENTS OR EXPECTATIONS, OR THAT ANY DEFECT WILL BE CORRECTED. EDUCATIONAL OUTCOMES INCLUDING GRADES, TEST SCORES, ADMISSION RESULTS, AND CAREER OUTCOMES DEPEND ON FACTORS OUTSIDE OF OUR CONTROL AND ARE NEVER GUARANTEED.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THESE EXCLUSIONS MAY NOT APPLY TO YOU. IN SUCH JURISDICTIONS, OUR WARRANTIES ARE LIMITED TO THE MINIMUM EXTENT PERMITTED BY APPLICABLE LAW.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL CALCULUS EDGE, ITS OPERATOR, OR ITS SERVICE PROVIDERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION LOSS OF PROFITS, REVENUE, DATA, GOODWILL, ACADEMIC STANDING, EMPLOYMENT, OR OPPORTUNITY, ARISING OUT OF OR RELATING TO YOUR ACCESS TO OR USE OF (OR INABILITY TO ACCESS OR USE) THE PLATFORM, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS OR THE PLATFORM, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STATUTE, OR OTHERWISE, SHALL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNT YOU PAID TO CALCULUS EDGE IN THE SIX MONTH PERIOD PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED UNITED STATES DOLLARS (USD 100).
THESE LIMITATIONS APPLY EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE. SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OR EXCLUSION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO SOME OF THESE LIMITATIONS MAY NOT APPLY TO YOU. IN SUCH JURISDICTIONS, OUR LIABILITY IS LIMITED TO THE MINIMUM EXTENT PERMITTED BY APPLICABLE LAW.
You agree to defend, indemnify, and hold harmless Calculus Edge and Andrew Finkelstein, and our respective officers, employees, contractors, agents, and licensors (collectively, the "Indemnified Parties"), from and against any and all claims, demands, suits, proceedings, losses, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to (a) your access to or use of the Platform; (b) your violation of these Terms; (c) your violation of any applicable law, regulation, or third party right (including any intellectual property right, privacy right, or right of publicity); (d) any content you upload, post, or transmit through the Platform; or (e) any dispute between you and a third party arising out of your use of the Platform. We reserve the right, at our own expense, to assume the exclusive defense and control of any matter subject to indemnification by you, in which case you agree to cooperate with our defense.
You may terminate these Terms at any time by closing your account. We may suspend or terminate your account and access to the Platform at any time, with or without notice, for any reason, including without limitation a breach of these Terms, suspected fraud, or non payment. Upon termination, your right to access the Platform ceases immediately. Sections that by their nature should survive termination will survive, including Sections 6 (license to uploaded content), 7 (intellectual property), 10 (disclaimer), 11 (limitation of liability), 12 (indemnification), 14 (dispute resolution), and 15 (governing law).
Informal resolution. Before filing any claim, you agree to first contact us at calculusedge@gmail.com and attempt in good faith to resolve the dispute informally for at least sixty (60) days.
Binding arbitration.If informal resolution fails, any dispute, claim, or controversy arising out of or relating to these Terms or the Platform, whether based in contract, tort, statute, fraud, misrepresentation, or any other legal theory, will be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules then in effect, except as modified by this Section. The arbitration will be conducted in the English language. The seat of arbitration will be Williamsburg, Virginia, or such other location as the parties mutually agree, and may be conducted virtually where practicable. The arbitrator's decision will be final and binding, and judgment on the award may be entered in any court of competent jurisdiction.
Class action waiver.YOU AND CALCULUS EDGE AGREE THAT EACH PARTY MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, REPRESENTATIVE, COLLECTIVE, OR PRIVATE ATTORNEY GENERAL ACTION OR PROCEEDING. UNLESS YOU AND CALCULUS EDGE BOTH AGREE OTHERWISE IN WRITING, NO ARBITRATOR OR JUDGE MAY CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS OR OTHERWISE PRESIDE OVER ANY FORM OF A CLASS OR REPRESENTATIVE PROCEEDING. THE ARBITRATOR MAY AWARD RELIEF (INCLUDING MONETARY, INJUNCTIVE, AND DECLARATORY RELIEF) ONLY IN FAVOR OF THE INDIVIDUAL PARTY SEEKING RELIEF AND ONLY TO THE EXTENT NECESSARY TO PROVIDE RELIEF NECESSITATED BY THAT PARTY'S INDIVIDUAL CLAIM.
Exceptions.Notwithstanding the foregoing, either party may bring an individual action in small claims court for any dispute within that court's jurisdiction, and either party may seek injunctive or equitable relief in court for the alleged infringement or other misuse of intellectual property rights.
Opt out. You may opt out of the arbitration agreement and class action waiver in this Section 14 by sending a written notice to calculusedge@gmail.com within thirty (30) days of first accepting these Terms. The notice must include your name, address, and a clear statement that you wish to opt out of arbitration. Opting out of this Section 14 will not affect any other provision of these Terms.
These Terms and any dispute arising out of or relating to them or the Platform shall be governed by and construed in accordance with the laws of the Commonwealth of Virginia, United States, without regard to its conflict of laws rules. Subject to Section 14 (arbitration), the parties agree to the exclusive personal jurisdiction and venue of the state and federal courts located in Williamsburg, Virginia for any matter that is not subject to arbitration. The United Nations Convention on Contracts for the International Sale of Goods does not apply to these Terms.
We will not be liable for any failure or delay in performance to the extent caused by circumstances beyond our reasonable control, including without limitation acts of God, natural disasters, fire, flood, earthquake, severe weather, pandemic, epidemic, war, terrorism, civil unrest, government action, labor disputes, internet or telecommunications outages, denial of service attacks, power failures, or failures of third party providers.
We reserve the right to modify these Terms at any time. We will indicate the date of the most recent revision at the top of this page. When we make a material change, we will use reasonable efforts to notify you, such as by posting a notice on the Platform or by sending an email to the address associated with your account. Your continued use of the Platform after the effective date of a revision constitutes your acceptance of the revised Terms. If you do not agree to the revised Terms, your sole remedy is to stop using the Platform.
We may give notice by posting on the Platform or by sending email to the address associated with your account. You may give notice to us by emailing calculusedge@gmail.com. Notice is effective on the date sent for electronic notice and on the date posted for Platform notices.
You may not assign or transfer these Terms or any of your rights or obligations under them, in whole or in part, without our prior written consent. Any purported assignment in violation of this Section is void. We may assign or transfer these Terms, in whole or in part, without restriction. Subject to the foregoing, these Terms will bind and inure to the benefit of the parties and their respective successors and permitted assigns.
If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, that provision shall be modified to the minimum extent necessary to make it valid, legal, and enforceable, or, if it cannot be so modified, severed from these Terms, and the remaining provisions shall remain in full force and effect. No failure or delay by either party in exercising any right under these Terms shall constitute a waiver of that right.
These Terms, together with our Privacy Policy and any other terms incorporated by reference, constitute the entire agreement between you and Calculus Edge regarding your use of the Platform and supersede all prior agreements, understandings, and communications, whether written or oral, regarding the subject matter.
