SHA-256 Verified

Never lose your
security deposit again.

Proof stamps every photo with cryptographic hashes, GPS coordinates, and timestamps the moment you capture it. Uneditable. Unchallengeable. Court-ready.

How it works

Three steps. Bulletproof documentation.

01

Capture

Open the camera. Take a photo. Behind the scenes, Proof records the timestamp, GPS location, and computes a SHA-256 hash of the raw image bytes before anything touches a server.

02

Organize

Tag photos by room. Review your project gallery with every piece of metadata visible. Living room, kitchen, front door, that weird stain that was already there when you moved in.

03

Export

One tap generates a professional PDF evidence package. Cover page, timestamped photos, GPS maps, hash verification, and a plain-English explanation of what it all means. Hand it to your landlord or a judge.

🔒

SHA-256 Digital Fingerprint

Every photo gets a cryptographic hash computed on your device before upload. Any alteration, even a single pixel, produces a completely different hash. Your photos are provably unmodified.

📍

GPS + Reverse Geocoding

Latitude, longitude, and a human-readable address captured with every shot. "742 Evergreen Terrace, Springfield, IL" not just "39.7817, -89.6501."

🕑

Precision Timestamps

UTC and local timezone recorded to the second. No ambiguity about when a photo was taken. Metadata that holds up in court.

📄

Court-Ready PDFs

Professional evidence packages with cover pages, photo metadata tables, GPS map pins, and hash verification sections. Designed to be understood by landlords, mediators, and judges.

The difference

Photos are opinions.
Proof is evidence.

Anyone can take a photo. Anyone can edit one too. Timestamps in file metadata are trivial to fake. EXIF data can be stripped or rewritten in seconds.

Proof creates a chain of custody for your photos. The SHA-256 hash is computed on the raw bytes at the moment of capture, on your device. It travels with the image forever. If the image changes, the hash won't match. Period.

Without Proof "I took this photo when I moved in"
With Proof "This image was captured at 742 Evergreen Terrace on May 18, 2026 at 3:42 PM. Hash: a7f3b2...verified."

Your apartment tells a story.
Make sure you control the narrative.

Proof exists because renters deserve better than "my word against theirs." Every photo you take with Proof becomes a piece of verifiable evidence that no landlord can dispute and no court can dismiss.
