SpamBlock: Call & SMS Blocker

SpamBlock combines SMS and MMS messaging with call rules and optional security tools.

SMS AND MMS MESSAGING
Choose SpamBlock as your default SMS app in Android to receive, read and send messages. Basic messaging does not require Premium.
• Read and reply to SMS in a conversation view.
• Send MMS with text and photos; tap incoming MMS to download through your carrier network.
• View or save MMS attachments.
• Follow sending, sent and failed states. View delivery status when your carrier supplies a delivery report.
• Choose a sending SIM on supported devices. SMS/MMS charges and mobile data requirements depend on your carrier.

OPTIONAL MESSAGE RISK ANALYSIS
With Premium and your consent, suspicious links and scam patterns in messages are evaluated on your device. Risk labels are assessments, not guarantees that a message is safe. Basic SMS/MMS messaging remains available when Premium ends.

CALL RULES AND PROTECTION
Manage individual numbers and prefixes such as 0850* with rules. Use safe lists, contact exceptions, a contacts-only mode and focus mode to control incoming calls. An explicitly blocked number or active focus mode may override contact exceptions.
Call protection uses Android’s separate caller ID and spam screening role. Choosing a default SMS app does not grant that role or call history access. Call protection and additional security features depend on your Premium plan; availability can vary by device and Android version.

WEB PROTECTION
Web protection uses Android VpnService for local DNS-based domain filtering. Domain lookups are sent to external DNS resolvers such as Cloudflare and Google. Coverage depends on browser and network settings; detection of every harmful site is not guaranteed.

COMMUNITY AND FAMILY
Optional community reports and family pairing are available. Family alerts can transmit the relevant number and event reason through Firebase to paired family members. These features depend on your plan and chosen settings.

YOUR DATA AND CONTROL
• Automatic message risk analysis runs on the device. Message history and contacts are not uploaded in bulk.
• Reports you explicitly submit may send the selected number, message text and description for review through Firebase.
• Optional community and family features use their disclosed cloud data flows.
• Sending SMS/MMS shares messages and attachments with your carrier and recipients.
• Personal data is not sold. Read the privacy policy for details.
• You can change your default messaging app in Android settings; SpamBlock then stops accessing messages.
