Accounts are optional. Without signing in, workout data and settings stay on your device. If you sign in, Clerk handles authentication and Supabase stores your configuration, workout history and free-workout usage. RevenueCat and your app store handle subscription status and purchases. There are no ads or app analytics.
Your settings (selected sport, body parts, timing values), custom trainings, the current workout and your workout history are saved in the app's local storage on your device. Signed-in workout history is also uploaded to Supabase. Active workouts are not uploaded. Signing out keeps the local copies; clearing app data deletes that local copy, but does not delete your Clerk account.
Supabase stores workout start time, duration, exercise count, sports and body parts under your Clerk user ID. When you sign in, known guest history and free-workout usage from this device are merged into your account. Account history is cached separately on the device and offline changes upload when connected. Clearing history deletes your account's cloud history when sync succeeds. See Supabase's privacy policy.
If you subscribe, the app store processes your payment and RevenueCat processes purchase and subscription-status information. VOLTSET does not receive your payment-card details. Your subscription is linked to your Clerk user ID so it can be recognized on supported devices. The app stores free-workout usage on your device and, when signed in, in Supabase under your Clerk user ID. See RevenueCat's privacy policy, Google Play's terms or Apple's privacy policy.
Signing in sends authentication information to Clerk. Selected sport, per-sport body parts, timing, theme, options, shuffle preferences, custom trainings and edited built-in sports (including their names and exercise lines) are stored in Supabase under your Clerk user ID. Do not put sensitive information in custom trainings. New accounts start with your local config; returning accounts restore the cloud copy. See Clerk's privacy policy for how Clerk processes account data.
All exercises, photos and sounds are included in the Android app. Guests can use their remaining free workouts offline. Signed-in free usage requires an account usage check. Subscribers can train using an active entitlement returned by RevenueCat's SDK, including its supported cached offline status; an unverified or expired entitlement does not grant access. Login and sync require internet and contact Clerk and Supabase. Purchases, restores and subscription updates contact RevenueCat and your store.
See account and data deletion for how to request removal of your Clerk account and associated Supabase data. Account deletion does not cancel an app-store subscription.
The app keeps the screen awake during a workout. It does not request access to your location, contacts, camera, microphone or files.
VOLTSET is intended for adults. Do not create an account if you are a child.
If this policy changes, the new version will be published on this page.
