This policy explains how to request help or a refund for a YooKassa purchase in Brainy: Trivia & Logic. Refunds for purchases billed by Google Play must be requested through Google Play or its support process.
Contact us if a confirmed YooKassa payment did not deliver the item, delivered the wrong item, was duplicated, or if another legal basis for a refund applies. A refund is not automatic: the seller first verifies the payment, delivery, entitlement use and any previous refund with YooKassa and the Brainy ledger.
Email maxdev@appyapp.org and include:
Do not send a password, full bank card number, card security code, raw Google Play purchase token or receipt signature.
We acknowledge support requests within 3 business days and aim to complete the review within 10 business days, unless the provider, bank, dispute or law requires more time. If approved, the refund is initiated through YooKassa to the supported original payment method. Bank settlement time is outside our control.
Where the digital item has already been fully consumed or used, refund eligibility may be limited except where applicable law requires otherwise. A technical delivery failure is first resolved by safely restoring the purchased entitlement when possible. No decision in this policy limits mandatory consumer rights.
YooKassa seller: Individual Entrepreneur Maksim Sergeevich Kochergin, Taxpayer ID 664605614840, Primary State Registration Number 317665800010998. Support: /support.
