Delete your Kelgramme data
Kelgramme does not create accounts: all your data (sessions, measurements, settings) is stored on your phone only.
Erase your data
Open Kelgramme, go to Settings, then tap "Erase all my data from this phone". Erasure is immediate and permanent. Uninstalling the app also deletes its data. If your phone's Google backup is turned on, a copy may remain in your Google Account: delete it in Android settings (Google, Backup). To have a message you sent to support deleted, write to us.
Premium subscription
Cancel in Google Play: Profile, Payments & subscriptions, Subscriptions. Uninstalling the app or erasing your data does not cancel the subscription. Payment data is managed by Google.
