Call Sentinel is built with one principle: your calls are YOUR business.
We do not see, collect, transmit, store, or process any call data from your device. Ever.
All call blocking, filtering, and detection happens entirely on your phone. There are no servers. No cloud. No tracking.
None.
Call Sentinel does not collect personal data, call logs, phone numbers, contacts, or any user information.
The app uses Android’s built-in call screening and blocking capabilities directly on your device. Decisions are made locally and never leave your phone.
No. There is no account system, no cloud sync, and no external storage of any kind.
No. Because we never have access to any data in the first place.
Why does the app need call permissions?
Android requires these permissions for any app that wants to block or screen incoming calls. The permissions are used locally on your device only.
Can you see who calls me?
No. We have zero visibility into your calls.
Is my data sent to the internet?
No. Call Sentinel works entirely offline.
Does Call Sentinel use analytics or tracking?
No analytics. No tracking. No telemetry.
