Your data
Where are my workouts?
They are stored in the app’s private storage on your iPhone. Sinew has no sign-in or developer-operated sync service. Your iOS device backup may include app data if backup is enabled.
How do I delete my workouts?
Open Settings in Sinew, then under Your data choose Delete all workouts. This removes workouts and routines from the app. Deleting the app removes its remaining local data from that device. Any CSV files you exported or device backups you made are separate.
Sinew Pro
How do I restore a purchase?
Open the Sinew Pro screen and tap Restore purchase. Use the Apple Account that made the purchase and connect to the internet so Apple can verify it.
Why are plans unavailable?
Sinew could not load products from the App Store. Check your connection and tap Try again on the Sinew Pro screen. Workout logging remains available.
CSV import and export
How do I move my training history?
With Sinew Pro, open Settings → Your data → Import & export. Sinew recognizes CSV exports from Strong, Hevy, and FitNotes. You can also export your Sinew workouts as CSV and choose where to save or share the file.
