Terms of Service
Last updated: November 11, 2026
1. Who we are
Ntrino Mentor (“Ntrino Mentor,” “we,” “us”) is operated by Ntrino LLC. By creating an account or using the service, you agree to these Terms.
2. What Ntrino Mentor is
Ntrino Mentor is an AI study mentor that combines explanations, worked examples, guided questions, practice, and remembered progress. Its learning estimates and study summaries are educational aids, not validated measures of attainment. It does not replace a teacher or provide professional, medical, legal, or mental-health advice.
3. Who can use it
You must be 18 or older to create an account and use Ntrino Mentor. Your account is for you alone; don't share it. You are responsible for the accuracy of the information you provide, including your date of birth. If we learn that an account belongs to someone under 18, we will close it and delete its information.
4. Your account
Keep your password confidential and your contact details current. You are responsible for activity under your account. Tell us promptly if you suspect unauthorized use.
5. Free trial, billing, cancellation, and refunds
Paid plans are billed monthly or yearly, as you choose, per account, at the price shown when you choose your plan. New accounts start with a 7-day free trial (longer with a creator's or club's code, as the sign-up page shows; codes can't be combined): you add a payment method when the trial begins and aren't charged until it ends. After that, your plan renews each month or each year, as you chose, until you cancel. For a yearly plan, we email you a reminder before each renewal. You can switch a monthly plan to yearly from your account: you're charged the yearly price at once, less the unused part of your month (during the free trial, the yearly price is charged when the trial ends). Refund policy: you can cancel anytime from your account. Your plan stays active until the end of the period you've already paid for, and you won't be charged again. If you cancel during the free trial, you won't be charged at all. We don't give refunds or credits for partial billing periods or unused time, except where the law requires it. If you believe you were charged by mistake, email support@ntrino.ai within 30 days of the charge and we'll review it and refund any charge made in error. Payments on the website are processed by Stripe; we never store full card numbers. Plans started in the Ntrino Mentor Android app are sold and billed by Google Play: Google Play shows the price and any free trial before you confirm, you cancel or change that plan in Google Play, and Google Play's terms and refund policies apply to it. The free trial is once per account, whether you start your plan on the website or in the app. A plan is managed where you bought it: how you pay for a website plan is changed on the website (you can also cancel or resume it in the app), and a Google Play plan is changed or canceled in Google Play, even on the website. If you start plans in both places, each is billed separately until you cancel it. If you delete your account, any plan is canceled at once and you won't be charged again; we don't refund the unused part of the period, except where the law requires it.
5a. Invites (give a month, get a month)
Members with a website plan can invite others with their own link. When someone who signed up through your invite makes their first website payment, you each get one month's price as credit, which comes off your next website payment. Credit has no cash value, can't be transferred or exchanged, and can't be given to a plan billed by Google Play. One member can earn a limited number of free months a year. We may withhold or remove credit gained by abuse, such as inviting yourself with another account. If you sign up through an invite, the member who invited you is told when they earn their free month (we don't tell them your name). We may change or end invites at any time; credit already given stays.
6. Acceptable use
Don't use Ntrino Mentor to break the law, to harm others, to attempt to extract complete graded answers in order to misrepresent them as your own where prohibited, or to misuse, probe, or disrupt the service. We may suspend accounts that violate these Terms.
7. AI limitations
Ntrino Mentor's responses are generated by AI and may be inaccurate or incomplete. Always verify important information. We are not liable for decisions made in reliance on AI output.
8. Safety monitoring
Automated screening may flag conversations for staff review and show crisis resources. It can miss or misclassify concerns, and does not guarantee detection, a response, or emergency assistance. Flagged conversations are excluded from study summaries. More detail is in our Privacy Policy.
9. Intellectual property
The service, its content, and its branding belong to us or our licensors. You keep ownership of the content you submit, and grant us the limited rights needed to operate and improve the service.
10. Disclaimers and liability
The service is provided “as is” without warranties of any kind. To the maximum extent permitted by law, our total liability is limited to the amount you paid us in the 12 months before the claim.
11. Changes and termination
We may update these Terms or the service; material changes will be posted here. You may stop using Ntrino Mentor at any time, and we may suspend or end accounts that violate these Terms.
