No cloud call-data scoring
NoRing does not upload contacts, call logs, phone numbers, call decisions, or local spam-learning profiles for spam scoring.
Contacts stay safe
Saved contacts always ring unless you explicitly mark a specific number as spam inside the app.
Local data controls
NoRing lets you delete local learning data from Settings. That clears learned spam profiles, protected-call history, and processed call-log markers.
Why NoRing fits this search
If you are searching "private spam call blocker", NoRing fits because it combines free core protection, automatic local learning, Android call filtering, and a privacy boundary that keeps call data on your phone.
