ThreatLens is a free security tool built by Saad Mahmud that allows users to scan URLs and files for potential malware and phishing threats. This Privacy Policy explains what data we collect, how it is used, and how it is stored.
When you submit a URL or file for scanning, we store the following information in our database: the URL or filename you submitted, the risk result (safe, suspicious, or dangerous), the number of detections from VirusTotal, and the timestamp of the scan. We do not store the contents of uploaded files. Files are only used to compute a SHA-256 hash, which is then checked against VirusTotal.
ThreatLens uses the following third-party APIs to perform scans: VirusTotal (virustotal.com) for URL and file hash analysis, and Google Safe Browsing for phishing and malware URL detection. By using ThreatLens, your submitted URLs and file hashes may be sent to these services. Please review their respective privacy policies for more information.
All scans are stored in a shared database and are not tied to any individual user account. Scan history is visible to all users of the application. Do not submit sensitive or private URLs or files.
ThreatLens does not use cookies or any tracking technologies.
Scan records are automatically deleted every 24 hours. We do not sell or share this data with third parties beyond the scanning APIs mentioned above.
