These terms form a legal agreement between you and QueryCase. If you have any questions, email hello@querycase.com before you sign up.
1. Acceptance of terms
By creating a QueryCase account or using the platform in any way, you confirm that you have read, understood, and agree to be bound by these Terms of Service and our Privacy Policy.
If you do not agree, do not create an account or use the service.
2. The service
QueryCase is an online SQL learning platform operated as a trading name in the United Kingdom. The platform provides:
- A structured Learning Path of SQL mystery Cases across five detective ranks
- Investigations -- timed Cases with harder constraints for experienced users
- Sandbox Mode -- free exploration of real-world datasets with no guided structure
- A Leaderboard and public profile pages showing XP, rank and progress
- A shareable Detective Certificate for each detective rank you complete
We reserve the right to modify, add, or remove features at any time. Where changes are material, we will provide reasonable notice.
3. Accounts
Creating an account
You must be at least 13 years old to create a QueryCase account. By registering, you confirm you meet this requirement. If we discover an account belongs to someone under 13, we will terminate it and delete associated data.
Account security
You are responsible for maintaining the confidentiality of your password and for all activity that occurs under your account. Notify us immediately at hello@querycase.com if you suspect unauthorized access.
Accurate information
You agree to provide accurate and complete information when registering and to keep it up to date. QueryCase is not liable for any issues resulting from inaccurate account information you provide.
4. Plans & access
QueryCase offers two tiers of access:
- ✓Full Rookie Detective path (8 Cases)

- ✓Select Sandbox schemas
- ✓Leaderboard and public profile
- ✓Full Learning Path -- all 54 Cases
- ✓All five detective ranks to Chief

The features included in each plan may change over time. If we remove a feature that was material to your purchase, we will notify you at least 14 days in advance.
5. Billing & payment
Pro is a one-time payment processed securely via Stripe. There is no subscription, no recurring charge, and no auto-renewal. You pay once and keep access. QueryCase never sees, handles, or stores your card details.
Prices are shown in your local currency where supported (for example $17.99 USD, €16.99 EUR, or ₹1,499 INR). The exact amount and currency are confirmed at checkout before you pay.
One-time purchase
Your purchase is a single payment for permanent access. Access does not expire and will never auto-renew, so you will not be charged again.
Price changes
We may change the price of Full Access for future purchases. Any price change applies only to new purchases and does not affect access you have already bought.
Failed payments
You are only charged when payment succeeds. If your payment does not complete, Full Access is not unlocked and you can retry the purchase at any time.
6. Refunds
All sales are final, except as set out below or where you have a statutory right to a refund. Full Access is a one-time purchase that unlocks digital content immediately, so by completing your purchase you acknowledge and agree that it is generally non-refundable.
24-hour goodwill window. If you change your mind, contact us at hello@querycase.com within 24 hours of your purchase and tell us why. We may, entirely at our discretion and depending on the circumstances, issue a refund. Refunds requested after this window are not guaranteed, and any goodwill consideration does not set a precedent.
Billing errors. If you believe a charge was made in error -- for example, a duplicate payment or a billing issue on our end -- contact us and we will review and correct it.
Your statutory rights. Nothing in these terms removes or limits any non-waivable refund or cancellation rights you may have under applicable consumer law.
We recommend using the free plan to evaluate QueryCase before purchasing Full Access.
7. Account & access
Because Full Access is a one-time purchase, there is no subscription to cancel and no recurring billing to stop. Your access does not expire and you will not be charged again.
Your progress, XP, rank, and case history remain associated with your account for as long as it is open.
To delete your account and all associated data, contact hello@querycase.com. Deleting your account does not entitle you to a refund except as set out in the Refunds section above.
8. Acceptable use
You agree to use QueryCase lawfully and respectfully. The following are prohibited:
Violation of these rules may result in immediate account suspension or termination without notice or refund.
9. Intellectual property
QueryCase content
All Cases, Investigations, Sandbox schemas, datasets, copy, course structure, visual design, and software are the intellectual property of QueryCase. Nothing in these terms transfers ownership of any QueryCase content to you.
We grant you a personal, non-transferable, non-exclusive license to access and use QueryCase solely for your own personal, non-commercial learning purposes while your account is active.
Your content
Your username and any content you submit to public areas of the platform (such as your profile) remain yours. By making this content visible on QueryCase, you grant us a limited license to display it as part of the service. We will never sell your content or use it for advertising purposes.
10. Detective Certificates
Each detective rank you complete -- by passing that rank's exam, from Rookie Detective up to Chief Detective -- earns you a Detective Certificate: a digital credential you can share publicly, including on LinkedIn.
A certificate confirms that you completed the relevant rank on QueryCase. QueryCase makes no guarantee, representation, or warranty that a certificate will be recognized, valued, or accepted by any employer, institution, or third party. It is a record of your achievement on our platform, not a regulated qualification.
Certificates are personal and non-transferable. Obtaining or sharing a certificate that was not legitimately earned violates these terms and may result in account termination.
11. Availability & changes
We aim to keep QueryCase available and reliable, but we cannot guarantee uninterrupted access. The service is provided "as is" and may be subject to downtime for maintenance, updates, or reasons outside our control.
We reserve the right to modify or discontinue any part of the service at any time. For material changes that affect Full Access, we will provide at least 14 days' notice by email. In the event we discontinue the service entirely, we will provide at least 30 days' notice. Where material changes significantly reduce the core features you paid for, you may request a refund in accordance with our Refunds policy.
12. Limitation of liability
To the fullest extent permitted by UK law:
QueryCase is a learning platform. We are not liable for any employment outcomes, interview results, salary changes, or career decisions made based on your use of the platform or your Detective Certificate.
We are not liable for any indirect, incidental, special, consequential, or punitive damages -- including loss of data, loss of revenue, or loss of opportunity -- arising from your use of or inability to use the service.
Our total liability to you for any claim arising from these terms or your use of the service shall not exceed the total amount you paid to QueryCase in the 12 months preceding the claim.
Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be excluded under English law.
13. Termination
Termination by you
You may close your account at any time by contacting hello@querycase.com. Closing your account does not entitle you to a refund of a one-time Full Access purchase, except as set out in the Refunds section above.
Termination by us
We may suspend or terminate your account immediately and without notice if you violate these terms, engage in fraudulent activity, or cause harm to the platform or other users. In such cases no refund will be issued.
On termination, your license to use QueryCase ends immediately. Your personal data will be handled in accordance with our Privacy Policy.
14. Governing law
These terms are governed by and construed in accordance with the laws of England and Wales. Any disputes arising from or relating to these terms or your use of QueryCase shall be subject to the exclusive jurisdiction of the courts of England and Wales.
15. Changes to these terms
We may update these terms as the product evolves or when legal requirements change. For material changes, we will notify you by email and with a notice inside the app at least 14 days before the new terms take effect.
Continuing to use QueryCase after updated terms take effect constitutes your acceptance of the changes. If you do not agree with updated terms, you should stop using the service and close your account before they come into force.
The "last updated" date at the top of this page always reflects the most recent revision.
