Terms of Service

By creating an account or using Dexico (the "Service"), you agree to these Terms of Service and to our Privacy Policy. If you do not agree, please do not use the Service.

Dexico is built for secondary school students, including IB, AP, IGCSE and college-prep students.

• If you are under 18, you confirm that a parent or guardian has reviewed and agreed to these terms on your behalf.
• If you are under 13, you may only use Dexico with a parent's or guardian's consent.

You are responsible for keeping your login details secure and for all activity under your account. Accounts are personal, so please don't share yours. If you suspect someone else has accessed your account, email us straight away at info@dexico.org.

You agree not to misuse the Service. This includes:

• attempting to hack, reverse engineer, disrupt or overload the platform
• trying to manipulate the AI tutors into ignoring their rules, or trying to extract their instructions
• scraping or copying Dexico's questions, simulations or other content with automated tools
• submitting harmful, abusive or unlawful content
• using Dexico to cheat on exams or coursework where your school or exam board prohibits it

Dexico's tutors are AI characters inspired by famous scientists, such as Newton and Euler. They are AI, and their personalities are for fun and engagement. Historical stories they tell may be simplified or playful.

Dexico uses AI to generate explanations, solutions, feedback and simulations. AI can make mistakes, and its answers may sometimes be incorrect or incomplete. Use Dexico as a study companion, and check important facts against your textbook, syllabus or teacher. Dexico does not provide medical, legal, financial or other professional advice.

Dexico is a practice and learning tool. It is not used for official grades, admissions or placement decisions, and teachers stay in control of any marks.

Our tutors can remember short notes about your learning so they can help you better across sessions. You can see and delete these notes in Settings, or ask any tutor to forget something. The Privacy Policy explains what is and isn't remembered.

Dexico's software, simulations, questions and other content are owned by Dexico and its licensors. You may use them only for your own personal study.

You keep ownership of the content you create, such as notes and essays. By using the Service, you give us a limited licence to store, process and display your content so we can run the Service for you. This licence ends when you delete the content or your account, except for copies we must keep by law.

If you send us feedback or suggestions, we may use them to improve Dexico without owing you anything.

Some features require a paid subscription. Prices, billing cycles and cancellation terms are shown at checkout. Subscriptions renew automatically unless you cancel before the renewal date. Cancelling stops future charges, and you keep access until the end of the period you've paid for. Refunds are handled as described at checkout and as required by law.

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. You can also write to us at info@dexico.org about any order.

Dexico is operated by Ansuman Mullick, the seller of the Dexico service. Paddle.com resells it to you as Merchant of Record.

You can ask for a full refund within 14 days of any payment, as set out in our Refund Policy. This adds to, and doesn't limit, any refund rights the law gives you.

A Founding School's Dexico Classroom subscription keeps the price it started with for as long as it stays subscribed.

If you use Dexico through your school, your school's agreement with us may also apply. Where it conflicts with these terms, the school agreement applies to that access.

You can stop using Dexico at any time and delete your account in Settings, under "Delete account", or by emailing info@dexico.org. We delete your data as described in our Privacy Policy.

We may suspend or close accounts that break these terms or put other users or the Service at risk. Where reasonable, we'll tell you why.

Dexico is provided "as is", without warranties of any kind. We do not guarantee that the Service will be uninterrupted, error-free or available at all times, or that it will improve any particular academic result.

To the extent permitted by law, Dexico is not liable for indirect or consequential losses arising from your use of the Service, including lost marks, grades or opportunities. Nothing in these terms limits any rights you have under consumer protection laws that cannot be excluded.

We may update these terms as Dexico evolves. If we make important changes, we'll tell you in the app or by email before they take effect, and we'll update the date at the top. If you keep using Dexico after the changes take effect, you accept the updated terms.

Dexico is operated by Ansuman Mullick. Questions about these terms? Email info@dexico.org, or write to us at Bilkent University Building 75, Çankaya, Ankara, Türkiye.
