Privacy
Nothing leaves your devices. This page says the same thing in more words.
What Plinth stores
Your sessions, sets, routines, exercise names, notes and settings. They live on your iPhone and, if iCloud is on, in your own iCloud account, so your Watch and iPad see them too.
What Plinth does not do
It collects no analytics, uses no advertising identifiers, and contains no third-party code that sends data anywhere. We cannot see your data: there is no account to attach it to and no server to send it to. Crash reports reach us only through Apple's opt-in system.
Apple Health
If you allow it, Plinth writes finished sessions to Health as strength-training workouts and reads your body weight. Plinth does not store or send Health data anywhere else. You can turn off either permission in the Health app at any time.
Import and export
Plinth reads imported files on your device and uploads them nowhere. Export makes CSV and JSON files that you own. If you send us a file to help fix the importer, we use it only for that and then delete it.
Purchases
The App Store handles subscriptions and the lifetime purchase. We receive no payment details and no personal information from a purchase.
Changes and contact
If this policy changes, the date below changes too. Questions: privacy@liftplinth.com.
