SafeOpen tells you what's behind a QR code or link before you tap. Open it. Don't open it. You decide. That sticker on the parking meter, the gas pump, the bathroom door — you don't know where it goes. Could be a real menu. Could be a fake. Could be a phishing page. Could be malware. Kids especially scan first and think later. SafeOpen scans the code with your camera, shows you the destination URL, and runs a safety check on your device — looking for known phishing patterns (fake login pages, look-alike domains, urgent-action prompts, suspicious URL structure). You see a Risk Level (Low, Caution, High, Unknown) with a plain-English explanation. Then you decide whether to open. WHAT IT DOES • On-device risk scoring — your scan never leaves your phone • Camera scanner for QR codes • Paste-a-link checker for sketchy URLs from messages or email • Scan history kept locally (free for the last 10, unlimited with credits) • Optional AI page summary so you know what's there before you commit (credit packs) WHAT WE WON'T PRETEND TO DO • No third-party reputation database. We don't ping Google Safe Browsing or paid threat feeds. Verdicts are heuristic, on your device, based on URL and content patterns. Treat them as "should I be careful?" — not a guarantee. • No account. No login. No tracking. The scanner is free and uses no network. • No screenshot preview of the destination — that's a future release. CREDIT PACKS (optional — scanning is free) • Starter: 100 credits at $0.99 • Standard: 500 credits at $3.99 • Power: 2,000 credits at $9.99 1 credit = 1 AI page summary. Credits never expire. PRIVACY The scanner runs locally. No account, no email, no history kept off-device. AI summaries (when you spend a credit) fetch the page through our backend — that request is short-lived and not tied to your identity. Built by Katafract LLC. Part of the Enclave platform.
