No subscription, no connection required, no data sent.

━━━━━━━━━━

📹 RECORD, AND KNOW WHO YOU'VE PASSED

The recording loops in segments while the recognition process works in parallel. Each license plate read is time-stamped and geolocated in a viewable and exportable history.

• Automatic segmentation; the oldest segments are automatically deleted
• 480p, 720p, or 1080p quality
• Time stamp embedded on the video
• Optional embedded detection frames
• Optional ambient sound
• Google Drive backup, destination folder of your choice

🛡️ KEEP THE EVIDENCE WHEN IT MATTERS

Loop recording always ends up overwriting the important moment. Not here.

• Accelerometer-detected impact: the clip is locked, never crushed
• Adjustable sensitivity to ignore potholes and speed bumps
• Locking also occurs upon detection of a tracked license plate, or on demand
• Export of a complete file: time-stamped PDF with location, videos, and SHA-256 hash of each file to prove they haven't been altered

🆘 SOS BUTTON

Emergency services will first ask, "Where are you?" A press displays your coordinates in their standard formats: degrees/minutes/seconds, decimals with precision, common area, in large print, ready to be read aloud. Copy or share with a single tap, call 112, and receive a prepared location message for your emergency contact.

🏠 GUARDIAN MODE

In a parking lot, condominium, or private property: be alerted when an UNKNOWN vehicle approaches, rather than the other way around. A webhook can trigger your home automation, gate opening, Home Assistant notifications, and custom scenarios.

🔔 YOUR OWN LISTS

Add the license plates you're authorized to track: your vehicles, your company's vehicles, and those authorized on your property. Receive audible and vibration alerts upon detection, and link a pattern and contact to each plate. Import and export in JSON format.

WHAT MAKES THE DIFFERENCE

🧠 Onboard Recognition
Vehicle detection, license plate location, optical reading, and super-resolution of distant images: all run on your phone. Adaptive day/night processing, simultaneous tracking of multiple vehicles, and validation of the French format.

🤖 Plaky AI Assistant
Configure the app using natural language: "activate the dashcam in 1080p," "stop scanning trucks." It also answers your questions about the features.

🔍 Navigation Mode
A resizable, floating window over Waze or Google Maps that continues scanning without interrupting your GPS.

🔌 External USB Camera
Connect a UVC camera for a fixed, road-facing framing with adjustable zoom. Ideal for permanent installation.

🎯 Multi-Scan
Reads multiple license plates simultaneously, useful in heavy traffic.

⚙️ Fine Settings
Types of vehicles to scan, strict or flexible license plate format, alert sound and duration, light or dark theme, 6 languages.

━━━━━━━━━━

🔒 PRIVACY

All recognition processing takes place on your device. License plates, history, and locations remain in an AES-256 encrypted database, protected by your phone's security module. Nothing is sent to our servers.

The only exception is the saving of videos to YOUR Google Drive, which you activate yourself. You can export or delete all of your data at any time.

WHO IS IT FOR?

• Drivers who want a dashcam capable of proving an incident
• Condominiums, parking lots, warehouses, and private sites (Security Guard Mode)
• Ride-hailing drivers, taxis, and delivery drivers, to document their journeys
• Company vehicle managers
