Local call protection
Recognizes repeat unknown call patterns locally and can decline matching calls before they ring when Android call filtering allows it. Saved contacts remain unaffected by default.
NoRing
NoRing is a free Android app for blocking repeat unwanted calls and managing SMS/MMS with local, on-device protection. It helps users keep promotional or suspicious messages quiet while important communication stays available in Inbox.
Android call and SMS/MMS protection with local decisions
NoRing is a free Android app for call and SMS/MMS protection. It is built to keep repeat unwanted callers quiet and move likely promotional or suspicious texts out of the way, while leaving important communication available on the device.
The app separates protection into two independently usable pillars: Call Protection and SMS Protection. Call Protection uses local learning and Android incoming call filtering to act on repeat unknown call patterns, while SMS Protection works as a full SMS/MMS app with Inbox, Quieted, search, compose, reply, and sender controls.
NoRing is designed around a local privacy boundary. Decisions happen on the phone, and the site says calls, contacts, numbers, SMS/MMS content, metadata, rules, and learning profiles are not uploaded for protection. SMS Protection requires NoRing to be the default SMS app, and RCS is not currently supported.
The product is available free, with optional NoRing Plus that removes ads while active but does not unlock stronger protection. Free users may see restrained ads on eligible safe screens, and no account is required for core use.
Core features
SMS/MMS message sorting
Keeps confident promotions and suspicious messages quiet while letting important alerts, personal messages, and uncertain conversations stay in Inbox.
Local SMS app workflows
Lets you browse a local Inbox and Quieted timeline, search messages, compose and reply, and review message context without uploading content for protection.
Sender rules control
Sender Rules let you change how a sender is handled, including always notify, mute, keep only important alerts, keep marketing quiet, or block.
Local history import
Imports and indexes existing SMS/MMS history locally so past conversations remain available after setup.
Private on-device decisions
Keeps call logs, contacts, phone numbers, message metadata, rules, and learning profiles on the phone; protection decisions do not rely on cloud or cross-user scoring.
Common use cases
Reduce repeat spam calls
Use Call Protection to keep repeat unknown callers from ringing when they match your own rejected or very short call patterns. This is aimed at users who want quieter phones without depending on a shared caller-ID database.
Filter promotional and suspicious texts
Use SMS Protection to move confident promotions and suspicious texts into Quieted while letting alerts, personal messages, and uncertain threads remain in Inbox. This fits people who want important messages to stay visible without a separate filtering app.
Manage message handling by sender
Use the local Inbox and Quieted timeline to review messages, search history, reply, compose new messages, and correct how a sender is handled with Sender Rules. This is useful when you need control after setup, not just automatic filtering.
Cover calls and messages together
Enable both pillars when you want one Android app to cover unwanted calls and SMS/MMS in a single local-first workflow. The product is set up in steps and can be expanded from one pillar to both later.
Stay local and account-free
Choose NoRing if you want protection without signing in and without uploading communication data for protection. The app is positioned for users who prefer private, on-device decisions over cloud scoring.
