Payment & Credits

Credit packs

All prices are in Canadian dollars: 100 credits for C$7.99; 250 for C$14.99; 500 for C$24.99; and 1,000 for C$39.99. Any applicable government taxes and the final total are shown before you confirm checkout. Your bank may apply currency conversion or other charges if you pay in a different currency.

When a credit is used

One credit is used for each new successfully processed answer sheet, including supplied sample files and camera scans of practice sheets. A PDF page counts as one sheet. A successfully recognized sheet can still need teacher review. Failed processing does not consume a credit; processing may temporarily reserve a credit until the outcome is known.

An exact repeat that the system recognizes as an already processed sheet in the same exam reuses its result without another credit. A different photo, crop or edit may count as a new sheet even if it belongs to the same student. Duplicate student IDs are checked separately and may need a teacher’s decision.

Editing a student ID, resolving review issues, changing marks, recalculating saved answers and reprocessing an existing scan through the Reprocess action do not use additional credits. Reprocessing requires a retained scan image. Public PDF downloads and printing do not consume credits.

Checkout and delivery

Credit purchases are one-time payments through Stripe when checkout is available. Nuvo Grade does not receive your full payment-card number. Credits are added after the server verifies successful payment; returning from checkout alone does not prove payment. Do not purchase again if confirmation is delayed—contact hello@nuvohubs.com with your payment reference.

Checkout may be unavailable while payment setup is incomplete. Test checkout is labelled as a test and is not a live purchase. Credits are account-specific, are not cash and cannot be transferred or redeemed for cash except where required by law.

Refunds and billing concerns

Contact hello@nuvohubs.com if you were charged incorrectly, did not receive purchased credits or want to request a refund of unused paid credits. Include your account email and payment reference, but never send a card number or password. Refund requests are reviewed individually; mandatory consumer rights are not restricted by this policy.

Used credits are generally not refunded merely because the result required review or an exam was deleted. Billing mistakes and service failures will be investigated. Any approved refund is normally returned to the original payment method, and the corresponding unused credits are removed. Bank processing times vary.

Price changes

We may change prices for future purchases. Changes do not reduce credits already granted or purchased. Credits do not expire. Any service discontinuation will be handled as described in the Terms of Service and applicable law.
