How it works
Evidence that holds up under scrutiny.
Three things happen the instant you tap the shutter — and they can't be undone, faked, or backdated.
- 01
Location is read on-device
Latitude, longitude, accuracy, altitude, and timestamp are captured at the moment of shutter — not added later.
- 02
Image is hashed
A SHA-256 fingerprint is generated from the original frame. Any later edit changes the hash and is detectable.
- 03
Bound into one record
Photo, metadata, and hash are stored together as a self-contained proof — exportable as a verifiable PDF.
Features
Built for the field, not the office.
Designed around how field crews actually work — fast capture, no friction, no dependency on connectivity or accounts.
Tamper-proof by default
Every photo gets a SHA-256 hash at the moment of capture. Edits are detectable.
Works offline
Capture, stamp, and queue evidence on remote sites. Sync when you choose to.
Private by default
No accounts, no analytics, no mandatory cloud. Your data stays on your device.
One-tap export
Generate verifiable PDF reports per job, ready for clients, insurers, or auditors.
