Terms
This is a minimal v1 policy describing the current state of mahir_data. It isn't legal advice, and it will be revised as the product grows.
mahir_data is a SQL interview-practice site with a free tutorial and a question bank, themed around companies with a real presence in Southeast Asia. All data is synthetic and generated for practice; no question reproduces a real interview question, and none contains any company's actual data.
Company and product names are trademarks of their respective owners, used here only to describe the subject matter of the practice material. mahir_data is not affiliated with, endorsed by, or sponsored by any company named on this site.
Creating an account lets us track your progress through the tutorial and question bank. You're responsible for keeping your account credentials secure.
The Basic plan is available as a recurring monthly or annual subscription billed via Stripe. You can cancel at any time; your plan reverts to free at the end of the current billing period.
The Interview Sprint is a single one-time charge granting 90 days of Basic access. It does not auto-renew and there is nothing to cancel — your plan reverts to free automatically when the 90 days are up.
If a plan isn't useful to you, email within 14 days of the charge and you'll get a refund — handled directly, not through an automated flow.
The AI coach feature is subject to fair-use monthly limits and an overall daily cap across all users, to keep the service available and prevent abuse.
The service is provided as-is, without warranty of any kind, including around interview outcomes. Practicing here doesn't guarantee results in a real interview.
