How does SpamShield detect SMS scams?

SpamShield uses AI and machine learning to analyze message content, sender patterns, and common scam indicators. It checks for phishing attempts, suspicious links, urgency tactics, and impersonation patterns. The system analyzes brand mentions, government impersonation, delivery scams, lottery schemes, and other common fraud patterns, and explains why it flagged a message.

Is SpamShield free to use?

Yes, SpamShield is completely free to use. There are no hidden fees, subscriptions, registration requirements, or limits on the number of messages you can analyze. We believe everyone deserves protection from scams.

Does SpamShield store my messages?

SpamShield never asks for your name, email, or phone number, and screenshots are read in your browser rather than uploaded in normal use. We do retain submitted message text to run the analysis and improve detection, without linking it to your identity. See our Privacy Policy for what we keep and how to request deletion.

What languages does SpamShield support?

SpamShield supports English, Chinese (Traditional and Simplified), Japanese, and Korean. The AI automatically detects the language and provides analysis in the appropriate language. It's particularly effective at detecting region-specific scams in each supported language.

Can I upload screenshots instead of typing text?

Yes! SpamShield features advanced OCR (Optical Character Recognition) technology that can extract and analyze text from screenshots. Simply upload an image of the suspicious message and our AI will read the text and provide a security analysis.

What types of scams can SpamShield detect?

SpamShield can detect a wide range of scams including phishing attempts, fake bank messages, government impersonation, delivery scams, lottery/prize schemes, tech support fraud, romance scams, account verification fraud, and many other types of fraudulent messages.

How fast is the analysis?

Analysis usually completes within a few seconds. Times can vary with message length and current demand.

Do I need to create an account to use SpamShield?

No account creation is required. SpamShield works immediately without any registration, login, or personal information. Simply visit the website and start analyzing suspicious messages right away.

What should I do if SpamShield identifies a message as dangerous?

If SpamShield identifies a message as dangerous, do not click any links, respond to the message, or provide any personal information. Delete the message immediately. For persistent scams, consider reporting them to your local fraud reporting agency such as the FTC, 165 (Taiwan), or your country's equivalent fraud hotline.
