The problem

Scam messages arrive when you are busy and worried: a parcel on hold, a bank code, a son writing from a new number. Many checkers ask you to send the message to their servers, and the people who most need help, often older parents, do not know who to ask. Being fooled also brings shame, so people stay quiet.

How Red Flag (Scam Checker) works

What you get

Private by design

Everything runs in this browser on your device. The message you paste is never uploaded, no blacklist is looked up and no link is opened. Red Flag only goes online when you type a Pro key, and then only the key is checked. Your history (Pro) is kept on this device and is not encrypted, so clearing site data or losing the device without a backup file loses it. Links to official reporting sites are plain links that open only when you tap them. The 💬 Feedback button sends only the text you type in it (with the app name and your language), and only when you tap Send.

Free vs Pro

Pro · $1 once
A private history of your checks, kept only on this device, and share cards with no 1usd.life mark. $1 once.

FAQ

Is Red Flag free?

Yes. Checking messages and links, the online-friend questions and the phone checklist are free, with no limit, in 15 languages. Pro is $1 once, not a subscription, with a 7-day refund.

Does a low score mean a message is safe?

No. Red Flag only looks for common patterns on your device. A new scam, a new web address or unusual wording can score 0. When money, a code or a password is involved, check with the real person or company yourself.

Is my message sent anywhere?

No. The check runs in your browser. Nothing you paste is uploaded, and Red Flag does not open or fetch the links in it.

Why does it not look links up on a blacklist?

Looking a link up would mean sending it to a server. Red Flag stays private, so it checks the shape of the address on your device instead. That means a brand-new dangerous site can slip through.

Can Red Flag tell if my phone has spyware?

No. The phone checklist is a guide you follow yourself. It cannot see inside your phone or detect spyware.

Does it replace my bank or the police?

No. If you lost money or feel unsafe, contact your bank and local authorities right away. Red Flag only shows links to official reporting sites for you to open yourself.
