Refunds

The 14-day refund

Within 14 days of a purchase, you can get a full refund of that purchase if none of your purchased credits have been used. Partner and referral credits you used do not count against this.

How to ask

Write to support@stud.com from the email address on your STUD account, with the purchase date and the pack. We reply within two business days.

An approved refund goes back to the original payment method through Stripe; banks usually post it within 5 to 10 business days. The credits from that purchase, including its bonus credits, leave your balance.

Runs that do not pass

A run's credits are spent when the run starts. A failed check is not refunded: you get the names of the checks that failed, with hints, and for a play your own AI produces, your AI can revise and submit again, up to 5 checked submissions within 7 days.

The credits for a run return to your balance only if STUD is at fault: its checker is unavailable, it cannot check the work on the inputs the run started with before any submission has been checked, or it cannot compute a play it computes itself (including when it does not deliver within 72 hours). That return is automatic. There is nothing to ask for.

Free credits

Partner, referral, and promotional credits are free and are not refundable.

After 14 days

Purchased credits never expire, so they stay in your balance for later runs. If you think something went wrong with a payment or a run, write to us anyway; we read every request.

Disputes

Please write to us before disputing a payment with your bank; most problems are faster to fix directly. If you do dispute a payment, the credits from it are removed from your balance.

If the law where you live gives you more than this page does, we follow the law.
