Public Offer Agreement
Version of 18 October 2026
ФОП Мостова Оксана Геннадіївна, a sole proprietor registered in Ukraine (the Provider), offers any individual or organisation (the Customer) an agreement for access to the Brainschool online learning platform on the terms below. Under articles 633 and 641 of the Civil Code of Ukraine this text is a public offer. This is a translation; where it differs, the Ukrainian version prevails.
1. Entering into the agreement
The offer is accepted — fully and without reservation — by paying for a plan. From the moment of payment the agreement is concluded in electronic form under the Law of Ukraine "On Electronic Commerce" and needs no signature on paper. Where access is paid for a child, the agreement is entered into by the child’s parent or other legal guardian.
2. Subject of the agreement
The Provider gives the Customer access to the Brainschool platform (brainschool.top) on the chosen plan for the period paid for: explanations of school topics, checked exercises, tests, exam preparation and an AI tutor within the plan’s limits. This is a supplementary educational service delivered online. The Provider is not an educational institution and issues no qualifications.
3. Plans and prices
The plans, what each includes, and their prices in hryvnia are published on the Pricing page. The price in force at the moment of payment stays fixed until the end of the period paid for. The Provider may change prices; a new price applies only to periods paid for after the change. A new student account gets a free trial — 3 days, up to 5 AI explanations a day; it needs no card and nothing is charged.
4. Payment
Payment is made online by Visa or Mastercard bank card through the monobank payment service (JSC UNIVERSAL BANK) on the site, and for schools and learning centres also by bank transfer against an invoice. A payment counts as made once the payment service confirms it or the funds reach the Provider’s account. Card details are processed by the payment service; the Provider neither receives nor stores them.
5. Access
Access opens in the Customer’s account automatically once payment is confirmed, usually immediately. There is no physical delivery: the service is provided through the website and the app. If access has not opened within 24 hours of payment, the Customer should get in touch using the details below — the Provider will open access or refund the payment.
6. Term and renewal
A subscription runs for one month or one year from the date of payment, depending on the period chosen. If the Customer turned on automatic renewal when paying, the next period is charged the same way on the day the current one ends. Renewal can be cancelled at any time from the account: access continues to the end of the period paid for, and nothing further is charged.
7. Refunds
Within 14 days of payment the Customer can have the full amount refunded, provided the plan’s paid features have not been used in that time. The conditions, procedure and timing are set out in the Refund Policy, which forms part of this agreement.
8. Rights and obligations
The Provider undertakes to provide access to the platform according to the plan paid for, to give advance notice of changes to these terms, and to process personal data as described in the Privacy Policy. The Customer undertakes to give accurate details at registration, not to share access to the account with third parties, and to follow the Terms of Use.
9. Liability
Each party is liable under the law of Ukraine. The AI tutor is a learning aid and can be wrong; the Provider does not guarantee any particular grade or exam result. The Provider is not liable for interruptions caused by circumstances outside its control, including failures of networks or service providers and force majeure. Nothing in this agreement limits the consumer rights given by the Law of Ukraine "On Consumer Protection".
10. Personal data
By paying for a plan the Customer agrees to the processing of personal data to the extent needed to perform this agreement. What is collected, why, and who can see it is described in the Privacy Policy.
11. Disputes
Disputes are settled by negotiation. A complaint can be sent to the Provider’s email address and is answered within 14 days. A dispute that cannot be settled this way is resolved under the law of Ukraine.
12. Changes to this offer
The Provider may change the terms of this offer by publishing a new version on this page with its date. A period already paid for is governed by the version in force at the moment of payment.
