SQLlearn
Terms of Use
These terms cover SQLlearn, also called SQL Learn, provided by Duvdex LLC, including test and store builds. They supplement the license and purchase terms of the store where you obtained the app; they do not replace them.
1. Learning and eligibility
SQLlearn provides practice lessons, sample datasets, query execution and progress tracking. Practice runs on your device. Lessons and results may contain errors and are not a professional certification or a guarantee of employment or a particular learning outcome. Check code before using it with real systems or data.
Follow the eligibility requirements of your store and applicable law. Where parental permission is required, a parent or guardian must authorize use and purchases. The app does not automatically verify age.
2. Optional Pro purchase
The optional Pro unlock is a one-time purchase, not an auto-renewing subscription. Its price, included content and applicable taxes are shown by your store before you confirm. No purchase is required to use the included free content.
Apple or Google processes payment, and RevenueCat validates access. Use Restore Purchases with the appropriate store account when available. A purchase does not promise transfer between different stores. Refunds follow your store's rules and applicable law. Removing the app does not itself refund a purchase. Do not send passwords or payment-card details to support.
3. Responsible use and content
Use the app and its materials only as permitted by your store license and applicable law. Do not interfere with the service, defeat purchase controls, or access another person's information. Submit or use only code and data you are authorized to use. These terms do not transfer ownership of your original practice code to Duvdex.
4. Privacy and local records
Data handling is explained in the Privacy Policy. Local progress can be lost when device storage is cleared or the app is removed. Store purchase records and operating-system backups are managed separately. Keep any practice work you need outside the app.
5. Availability and your rights
Features and test builds can be unavailable or change. We do not promise uninterrupted operation or error-free lessons. Nothing in these terms excludes warranties, refunds, remedies or other rights that applicable law does not allow us to exclude. Apple's standard app license continues to apply where your Apple purchase is subject to it.
6. Contact and updates
Contact Duvdex LLC at support@duvdex.com. Updated terms will be dated. We will provide notice of material changes as required by applicable law before applying them.
