About this app

Lucent is a 66-tool intelligence and privacy kit for your phone. There is no account, no Lucent server and no API key. Every lookup goes straight to a public source or never leaves the device.

LOOK UP ANYTHING PUBLIC

IP Intelligence, DNS Toolkit, IP to host, Domain WHOIS, Domain Links, ASN and BGP, HTTP Inspector, TLS and certificate inspector, Site Status, Subdomain Finder, Site Contacts, Username Footprint.

Resolve an address, read a domain's records or trace who owns a network. Domain Links finds the domains one is tied to through shared certificates, nameservers and addresses. Site Status settles whether a site is down for everyone or only for you. Username Footprint checks a handle against 100 public sites.

CHECK IT BEFORE YOU TRUST IT

Message Inspector reads a pasted text or email on the device: where each link really goes and whether its payment details pass their own checksums. Threat Lookup unmasks a link and rates its risk, and QR Safety Scanner checks a scanned code before anything opens. Sample Match compares two faces or two voices on the device. Email Header Analyser traces every hop and gives the SPF, DKIM and DMARC verdict. APK Inspector verifies an installer's signature. Phone Intelligence returns a number's carrier, line type and region offline.

KNOW THE THREAT LANDSCAPE

Security Feed carries the day's reporting from eight publications beside the catalogue of actively exploited CVEs. Malware Index is an offline reference of more than 990 malware families, their aliases, groups and techniques.

SEE YOUR OWN FOOTPRINT

Check an email against known breaches and its public Gravatar profile. See what a stranger finds on your GitHub, and what a website reads from your device. File Metadata reads every byte of metadata in photos, video, audio, documents, PDFs and archives, then strips it, and verifies Content Credentials (C2PA). Device Integrity checks for root and an unlocked bootloader by hardware key attestation.

MEASURE THE WORLD AROUND YOU

Wi-Fi analyser, Bluetooth scanner, cellular signal, GNSS satellites, NFC reader and writer, network scanner, port scanner, traceroute, speed test, DNS control, network diagnostics, EMF meter, light meter, compass, sound level meter, vibration meter, an ultrasonic tone monitor and a diagnostics suite that audits every sensor against its driver and physics.

Tracker Watch shows whether a Bluetooth item finder is travelling with you. Capture Reader reads a packet capture into its connections. Geotag Camera stamps place, time, weather and sensor readings into a photograph or recording. LAN Remote, IR Remote and Bluetooth Remote turn the phone into a remote for televisions, media players and computers.

OFFLINE UTILITIES

Hashing, encoding, JWT decoding, IPv4 and IPv6 subnet maths, password strength, passphrase generation, MAC vendor lookup across the IEEE registry, OpenPGP key generation and signing, and a 473-code reference across 17 protocols. Document Check finds text left under a redaction box and earlier revisions. File Encryptor locks any file with AES-256 behind a passphrase only you hold. Code Lab runs shell, JavaScript and Lua scripts on the device.

WHAT MAKES IT DIFFERENT

There is no Lucent server. Nothing you look up is logged, retained or profiled by Lucent, because there is nowhere to put it. Settings lists every public source the app can reach, tool by tool, and what each is asked.

Lucent reports infrastructure and reputation. It will not resolve a person to a name, a face or a home. A source that is rate-limited or unreachable is reported as inconclusive, never guessed.

ABOUT PERMISSIONS

Each permission is requested only when you open the tool that needs it. The signal tools ask for location because that is how Android gates radio scanning; Geotag Camera and Tracker Watch also read the phone's own position. Lucent never locates anyone else. Scan only networks and devices you own or are authorised to test.
