About this app

Track every rep, set, and personal record, and get AI-generated workout plans built around your goals.

Kosher is a gym tracker built on one principle: your workout data belongs to you, not us. No account. No cloud. No tracking. Every session, exercise, and personal record is stored locally on your device and never leaves it, and backed up to your Google Drive.

GENUINELY PRIVATE
──────────────────────────────

Most fitness apps require an account. Kosher does not. We cannot see your workouts. We do not track your sessions, your body measurements, or how you use the app. There is no server to breach. No data is transmitted in the background.

Your data lives on your phone. Uninstalling the app deletes it permanently. That is the only way it leaves your device.
