NaviRing makes calls from OTT apps ring on your Bluetooth watch. The app has no Internet permission, no account, and no third-party analytics or ad SDKs. Data is processed on your phone and is not sent to us or anyone else.
| Data | Purpose | Where and how long |
|---|---|---|
| Incoming-call notifications from OTT apps you enable (caller name, call state, answer/decline buttons) | Detect calls, show the name on the watch, forward answer/decline from the watch | Memory only, during the call. Other notifications and message content are ignored immediately, never read or stored |
| Caller name and app name (e.g. "Zalo · Minh Anh") | Let the watch look up the name over Bluetooth | Stored in a separate on-device account named "NaviRing" (Contacts) with a 16-digit placeholder number that cannot be dialed. Deletable anytime under "Saved caller names". This account is never synced to the internet |
| Your contacts | Not used. The app only creates, reads and deletes entries it created itself | — |
| Caller name and call ID of apps that send their own calls to the watch (such as Messenger) | Create a temporary name card so the watch shows the name for these calls | On device only, in the "NaviRing" account; the temporary card is deleted a few seconds after the call ends |
| Watch Bluetooth address and name | Link the watch so the app starts when it connects | On device until uninstall |
| Technical log (event codes, times, OTT app package, error codes) | Troubleshooting | On device, up to 300 lines; no names, numbers or content. Leaves the phone only if you tap "Share" |
| Settings (enabled OTT apps, on-duty state) | Remember your choices | On device |
utm_source=naviring) for install statistics; no personal data is included.| Permission | Reason |
|---|---|
| Notification access | Detect incoming-call notifications from OTT apps |
| Contacts (read/write) | Save caller names so the watch shows them; without it the watch shows a number |
| Manage own calls (MANAGE_OWN_CALLS) | Create a call on the phone so the watch rings; no cellular call, no charges |
| Companion device (watch) | Start automatically when the watch connects |
| Manage ongoing calls (granted with the watch role) | Detect when an OTT app already sends its own call to the watch, to avoid a duplicate; read the caller name and call ID that app provides only to create a temporary name card. That call is not controlled |
Turn off "Ring my watch for app calls", disable individual OTT apps, delete saved names, revoke permissions in Android Settings, or uninstall the app (Android removes the NaviRing account and saved names).
The app is not directed at children under 13 and does not knowingly process children's data.
