IMPORTANT PRISMARING DISCLOSURES:
• Ring readings are held on your phone only until they are uploaded, encrypted with a key kept in the device's secure keystore, excluded from backups, and deleted from the phone as soon as the upload succeeds.
• Ring readings are transmitted securely (TLS 1.3) to our servers solely for generating personalized health insights correlated with your genetic profile.
• The app uses Bluetooth while it is open. It keeps the connection on in the background only to finish something already in progress: a workout or a vitals check that you started (at most 60 minutes for a workout, about 2.5 minutes for a vitals check), so the ring's readings keep recording with the phone locked or in your pocket; or a sync of the ring that began while the app was open, which takes a few seconds. The connection closes as soon as that ends. The app never starts a connection, a sync or a scan for rings in the background. When a sync finishes after you have left the app, the iOS app can show a notification with how many readings were uploaded (never the readings themselves); it is created on your device and not sent through any push service.
• While a workout or a vitals check runs, the iOS app can show it on the Lock Screen and in the Dynamic Island (a Live Activity) with your current heart rate and readings; while a ring sync runs, the same place shows its progress and how many readings were uploaded. It is displayed on your device only, updated by the app itself, and not sent through any push service. You can turn Live Activities off in iOS Settings → LifePrisma.
• Ring data is NOT used for advertising, marketing, or data mining, is NOT sold or shared with third parties for those purposes, is NOT used to determine insurance eligibility, coverage, or pricing, and is NOT shared with data brokers.
• You may unpair the ring at any time from the app; upon account deletion, all ring-derived data is permanently deleted from our servers.
