Privacy Policy

Effective September 17, 2026

Efficiency Strength Training, LLC operates BAR MATH. This policy explains what information the app processes, why it is used, and the choices available to you.

Information we collect

Most training progress and settings remain on your device. If you choose to submit a leaderboard score, we collect the display name you provide, an app-generated client identifier, score and accuracy information, game mode, difficulty, and submission time.

Our service also processes network information and stores a short-lived, one-way hashed network identifier to prevent abuse and enforce rate limits. We do not use this information to identify you or for advertising.

How we use information

We use collected information only to operate leaderboards, show your ranking, maintain app functionality, protect the service, diagnose problems, and prevent fraud or abuse. We do not sell personal information or use it to track you across apps or websites.

Public leaderboard information

A submitted display name and score may be visible to other BAR MATH users. Do not use your full legal name or include contact or other sensitive information in your display name.

Service providers and retention

We use hosting and database providers to run the app. They process information on our behalf to provide those services. Leaderboard records are retained while needed to operate the leaderboard. Security rate-limit records are temporary. Local progress can be removed by clearing the app's data or deleting the app.

Children

BAR MATH is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact us so we can review and delete it where appropriate.

Your choices

Leaderboard submission is optional. You may use the app without submitting a display name or score. To request access to or deletion of leaderboard information associated with you, contact us using the information below and include the display name involved.

We may update this policy as the app changes. The effective date above will be updated when revisions are published.
