Two ways to unlock more
Ultra removes every wall for good. Credit bundles top up Sprint Coins if you would rather pay as you go. Access and coins are granted by hand for now, a reply to your email is all it takes.
Ultra
Unlocks every hint and solution in QueryLab, removes ads, and removes all credit friction. Pay once, keep it.
Email for Ultra accessCredit bundles
Top up Sprint Coins to spend on hints and solutions, without committing to Ultra.
Payment methods
Access and coins are granted manually for now and take a reply, usually the same day. No payment inputs of any kind exist in this phase. Zero payment data is collected or stored.
What is coming
A hosted checkout is next, card and UPI data will live with the payment provider only and never touch our servers. Until then, every unlock here goes through the same reviewed path an automated purchase will use later, so going live is wiring, not rework.
