StuFlex

Terms of Service

Last updated October 26, 2026

These terms are an agreement between you and Rehaan Irfan, who runs StuFlex (“StuFlex”, “we”, “us”) from the State of Washington, USA. By creating an account or using StuFlex, you agree to them. If you don’t agree, please don’t use StuFlex.

Who can use StuFlex

StuFlex is for students aged 13 and older. If you’re under 18, a parent or guardian must agree to these terms before you use StuFlex, and you confirm that they have when you sign up. A parent or guardian who agrees, or who pays for the plan, is also responsible for payment. We don’t knowingly allow anyone under 13 to use StuFlex; if we learn that someone under 13 has an account, we delete it.

Your account

Give true details when you sign up, including your date of birth. Keep your password private, don’t share your account, and let us know if you think someone else has used it. You’re responsible for what happens in your account. You can delete your account at any time from your Account page once any plan has ended.

The free problem and the plans

  • Your first problem is free. After that, you can choose StuFlex at $10 per month or StuFlex Plus at $20 per month, plus any tax added at checkout. StuFlex Plus has larger monthly, daily and voice allowances.
  • You can switch plans from My plan → Manage billing, and Stripe shows the new price before you confirm. Moving up to StuFlex Plus starts right away, and you’re charged the difference for the rest of the billing month. Moving down to StuFlex starts at your next billing month.
  • The plan renews automatically every month until you cancel, and each month is charged to your payment method on file. You agree to this when you tick the renewal box before checkout.
  • You can cancel at any time from My plan → Manage billing, or at link.com. You keep access until the end of the month you’ve paid for, and you won’t be charged again.
  • Each plan includes a monthly allowance of lessons and natural voice, which refills when your plan renews. My plan shows how much is left. Once the voice allowance is used, Ollie switches to your browser’s built-in voice; once the lesson allowance is used, lessons pause until renewal. There is also a daily limit, which pauses lessons until the next day (UTC) if it’s reached.
  • If the price changes, we’ll email you at least 7 days and no more than 30 days before the change, and it won’t apply until your next billing month. You can cancel before then.

Who you’re buying from

Payments are processed by Stripe and sold through Link, Stripe’s checkout service, which acts as the seller of record. Your receipts come from Link, and charges appear on your statement as “LINK.COM* STUFLEX”. Refunds follow our Refund Policy.

Ollie is an AI

Ollie is an artificial intelligence. Ollie can make mistakes, including in math, so check important answers yourself. StuFlex is a study aid, not a replacement for your teacher, and it doesn’t give professional (for example legal, medical or financial) advice.

Not for emergencies

StuFlex isn’t a crisis or counselling service. If you or someone you know is in danger or thinking about self-harm, call or text 988 (the Suicide & Crisis Lifeline in the US) or call 911, and talk to a trusted adult.

Use StuFlex to learn

StuFlex is built to help you understand math. Follow your school’s rules on homework, tests and AI tools, and don’t hand in Ollie’s work as your own where that isn’t allowed.

Things you may not do

  • Use StuFlex to harass anyone or to create anything unlawful or harmful.
  • Upload other people’s personal information, or anything you don’t have the right to share.
  • Scrape, copy or resell StuFlex, or use it to build a competing service.
  • Try to get around the allowances, access controls or security, or overload the service.

We may suspend or close accounts that break these rules.

Your content

You keep ownership of the questions, photos and work you add. You let us store and process them only to run StuFlex for you, as described in our Privacy Policy.

Ending your account

  • You can stop using StuFlex at any time. Cancel your plan from My plan → Manage billing, and delete your account from your Account page once the plan has ended.
  • We may suspend or close your account, with or without notice, if you break these terms, if we have to by law, or to protect students, other users or StuFlex. If we close an account for any other reason, or stop offering StuFlex altogether, we’ll tell you at least 30 days ahead where we can and refund the unused part of any month you’ve already paid for.
  • When an account ends, your right to use StuFlex ends too, and we delete your data as described in our Privacy Policy. The sections on warranties, liability, indemnification, disputes and the law that applies still apply afterwards.

Disclaimer of warranties

We work hard to keep StuFlex accurate and available, but STUFLEX IS PROVIDED “AS IS” AND “AS AVAILABLE”. AS FAR AS THE LAW ALLOWS, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY AND NON-INFRINGEMENT. We don’t promise that StuFlex will be uninterrupted, secure or error-free, that Ollie’s answers will be correct, or that using StuFlex will improve your grades.

Limitation of liability

AS FAR AS THE LAW ALLOWS, WE ARE NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST GRADES, PROFITS, DATA OR OPPORTUNITIES, ARISING FROM YOUR USE OF STUFLEX, EVEN IF WE WERE TOLD THEY WERE POSSIBLE. OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO STUFLEX IS LIMITED TO THE GREATER OF THE AMOUNTS PAID FOR YOUR STUFLEX PLAN IN THE 12 MONTHS BEFORE THE CLAIM, OR US$50. These limits don’t apply to liability that the law doesn’t allow to be limited, such as for fraud, or for death or personal injury caused by negligence.

Indemnification

You agree to defend and indemnify us, and hold us harmless, against third-party claims, and the reasonable costs and legal fees that come from them, arising from content you add to StuFlex, your breaking these terms, or your breaking the law or someone else’s rights. This doesn’t cover claims caused by our own fault. We’ll tell you about any such claim and let you take part in how it’s handled. If you’re under 18, the parent or guardian who agreed to these terms for you accepts this on your behalf.

Changes to these terms

We may update these terms. If a change is significant, we’ll tell you in the app or by email before it takes effect. If you keep using StuFlex after that, the new terms apply.

Governing law

These terms, and any dispute about them or about StuFlex, are governed by the laws of the State of Washington, USA, and applicable US federal law, without regard to conflict-of-law rules.

Dispute resolution

If something goes wrong, please contact us at rehaan_irfan@outlook.com first and tell us what happened. We’ll both try in good faith to sort it out informally within 30 days. If we can’t, either of us may take the dispute to the state or federal courts in King County, Washington, which have exclusive jurisdiction, unless consumer law where you live gives you the right to bring it locally. Either of us may also bring an individual claim in small claims court if it qualifies.

General

If any part of these terms can’t be enforced, the rest still applies. If we don’t enforce a right straight away, we haven’t given it up. You can’t transfer your account or these terms to someone else; we may transfer them if StuFlex is sold or reorganised, and we’ll tell you if that happens. These terms, with our Privacy Policy and Refund Policy, are the whole agreement between you and us about StuFlex. Questions? Contact us at rehaan_irfan@outlook.com.
