Get in touch

For help, bug reports, or privacy questions, email abeckerman007@gmail.com.

For a bug report, include the problem title, what happened, your iPhone model, iOS version, and SQLGym version from Settings. Use only fictional data in query examples. Never send passwords or sensitive personal information.

Practicing offline

The practice datasets and SQL engine are included in the app. You can run queries without an internet connection or an account.

Your progress

Drafts, attempts, solved problems, and streaks are stored on your iPhone. They do not sync across devices. Deleting the app can erase your progress; avoid reinstalling as a troubleshooting step unless you are comfortable losing that data.

Query errors

Check the table and column names against the problem’s schema. Queries must be read-only analytical queries. Queries that exceed the time or result limits stop so you can revise and try again.
