Purchase terms / Edition 1.0
What your purchase includes.
Backend Drills is operated under the SlickNext trade name. Customer support: support@slicknext.com. Updated October 6, 2026.
Product and price
The full Backend Drills edition is a one-time $29 USD purchase for one person's authenticated online access to 200 fictional backend scenarios, 600 decisions, supplied explanations, a printable companion field guide, and a 14-day foundations plan. There is no recurring subscription.
Future editions, ongoing content additions, coaching, certification, hiring outcomes, or perpetual availability are not promised. Do not rely on the purchase as a lifetime-access guarantee.
Account and access
Use a modern browser with JavaScript and internet access. Paid access follows the account used for checkout. Learning progress and notes remain in that browser and do not sync between devices. You may use the edition on your own devices; redistribution, resale, account sharing, or publishing paid content is not included.
Stripe processes payment. Access is granted only after payment is verified by the application. A checkout return page by itself does not unlock the product. If access is missing, sign in to the same account and use Recover purchase, then contact support if needed.
Refund requests and disputes
If you believe a purchase was made in error, the product was materially unavailable, or another issue warrants a refund, contact support@slicknext.com as soon as practical with the purchase email, approximate date, and receipt or order reference. Do not send card details, passwords, or verification codes.
Refund requests are reviewed in good faith and are subject to applicable law and the circumstances of the purchase. No automatic refund window is promised by these terms. If Stripe confirms a partial or full refund or a payment dispute, access associated with that payment may be disabled.
Educational scope
The scenarios are fictional educational exercises. Illustrative code is not executed. Scores and explanations are learning feedback, not professional advice, certification, hiring predictions, or guarantees of interview or employment results.
Privacy and providers
Clerk provides account authentication, Stripe processes payments, and Cloudflare hosts the application and access database. See the Privacy page for more detail.
Support
For purchase, access, or account-support questions, email support@slicknext.com. These terms apply to the current online edition and may be updated for future purchases when the product or business changes.
