Scam calls. Fake delivery texts. Fraudsters pretending to be your bank.

These attacks are getting harder to spot — and one wrong tap can have serious consequences. Filtro is your personal shield against phone fraud, built for everyday people who just want to know: is this real?

— HOW IT WORKS —

When a business calls you, Filtro instantly checks whether that number belongs to a verified, legitimate company. No more guessing. No more anxiety. You see a clear badge — Verified, Unknown, or Suspicious — before you even say hello.

When you receive a text message, Filtro can analyse it directly on your device whenever you choose. It looks at the sender information, the links inside, the urgency of the language, and dozens of other signals to tell you whether the message is safe or a phishing attempt. The result appears in seconds.

— COMPLETELY PRIVATE BY DESIGN —

We built Filtro around one principle: your data is yours.

For SMS analysis, everything happens locally on your phone. Your messages are never uploaded, never sent to any server, never stored anywhere outside your device. Not a single character leaves your phone.

For call verification, only the phone number is checked. No name, identity, or contact information is transmitted

We store no personal data. We do not create a user profile. You are not the product.
