Seven-day full refund
Individual annual and monthly payments may be requested for a full refund within seven calendar days of the initial or relevant renewal payment. The related access is removed when the payment provider confirms the refund.
Research packs and excluded products
A research pack is eligible for a refund only while all three credits remain unused. Once any credit is used, it is outside this voluntary refund promise. Gift annual codes and team codes are also excluded, except where mandatory law requires otherwise. Report duplicate or unauthorized payments promptly.
Canceling renewal
Canceling monthly membership stops the next charge and does not refund the current period. Normal cancellation preserves access through the paid period.
Requests and timing
Contact support from the registered email with the order date and issue. Do not send full card details. Approved refunds return to the original payment method; timing is controlled by the payment provider, card networks, and banks.
Disputes
Contact support before filing a chargeback when possible. A dispute pauses the related access and preserves order, communication, and access evidence. The payment institution makes the final dispute decision.
